-
- . Implement recursive NLST downloads by trying to CD to each filename.
- If it works, it's a directory; if not, it's a file -- GET it. But
- that won't work with servers like wu-ftpd that don't send directory
- names. Recursion with MLSD is done.
-
- . Make syslog entries for session? Files?
-
- . Messages are printed to stdout and stderr in random fashion. We should
- either print everything to stdout, or else be systematic about when
- to use stderr.
-
- . Implement mail (MAIL, MLFL, MSOM, etc) if any servers support it.
-
- . Adapt to VMS. Big job because of its record-oriented file system.
- RMS programmer required. There are probably also some VMS TCP/IP
- product-specific wrinkles, e.g. attribute preservation in VMS-to-VMS
- transfers using special options for Multinet or other FTP servers
- (find out about STRU VMS).

- How to get the struct timeval definition so we can call select(). The
- xxTIMEH symbols are defined in ckcdeb.h, overridden in various makefile
- targets. The problem is: maybe we have already included some header file
- that defined struct timeval, and maybe we didn't. If we did, we don't want
- to include another header file that defines it again or the compilation will
- fail. If we didn't, we have to include the header file where it's defined.
- But in some cases even that won't work because of strict POSIX constraints
- or somesuch, or because this introduces other conflicts (e.g. struct tm
- multiply defined), in which case we have to define it ourselves, but this
- can work only if we didn't already encounter a definition.

-0. WHAT'S NEW
-
- The Initialization and Customization Files
- C-Kermit 8.0 now supports specification of the initialization
- file name (path) in an environment variable, CKERMIT_INI. It
- also relies far less than before on the initialization for
- functioning. See [125]Section 5 of the Unix C-Kermit
- [126]installation instructions for details. As of version
- 8.0.201, C-Kermit also executes your customization file (if you
- have one) even if the initialization file was not found.
- Previously, the customization file was executed by a TAKE
- command in the initialization file (and it still is, if an
- initialization is found).
-
- Incompatible Changes
- As always, we do our best to avoid changes that break existing
- scripts. However, C-Kermit 8.0 does include a rather pervasive
- syntax change that might alter the behavior of scripts that
- depend on the previous behavior. As described in [127]Section
- 5, C-Kermit now accepts doublequotes in most contexts where you
- previously had to use braces to group multiple words into a
- single field, or to force inclusion of leading or trailing
- blanks. Most noticeably, in C-Kermit 7.0 and earlier:
-
- echo {this is a string}
-
- would print:
-
- this is a string
-
- whereas:
-
- echo "this is a string"
-
- printed:
-
- "this is a string"
-
- In C-Kermit 8.0, both print:
-
- this is a string
-
- To force the doublequotes to be treated as part of the string,
- use either of the following forms:
-
- echo {"this is a string"}
- echo ""this is a string""
-
- Similarly, to force braces to be treated as part of the string:
-
- echo "{this is a string}"
- echo {{this is a string}}
-
- Other incompatibilities:
-
- 1. Using the SET HOST command to make HTTP connections is no
- longer supported. Instead, use the new HTTP OPEN command,
- described in [128]Section 2.2.
-
- C-Kermit 7.1 Alpha.01 (8 December 2000)
-
- Its major new features are those listed in the [129]Table of
- Contents: the FTP client, file scanning, command parsing and
- scripting improvements, S-Expressions, and support for the
- Telnet Com Port Option, plus wider availability of the
- Kerberos, SSL/TLS, and SRP security options for secure Internet
- connections.
-
- C-Kermit 7.1.199 Alpha.02 (4 January 2001)

- rename a file as indicated by the template after it has been
- sent completely.
- + FTP [136]VDIRECTORY added for getting verbose directory
- listings from TOPS-20.
- + [137]FTP TYPE TENEX added for transferring 8-bit binary files
- with PDP-10s.
- + Added [138]automatic text/binary mode switching for FTP
- [M]GET, based on filename patterns (e.g. *.zip, *.gz, *.exe
- are binary; *.txt, *.c are text).
- + [139]SET SEND I-PACKETS OFF added for coping with Kermit
- servers that do not support I packets.
- + A new option was added to [140]\fword() and \fsplit() for
- parsing comma-separated lists that might contain empty
- elements.
- + Bug fixes including:
- o {} or "" could not be used as expected to represent the
- empty string.
- o ,- on a line by itself in a macro definition caused
- subsequent statements to be skipped.
- o FTP [M]GET didn't work right if path segments were

- * SET TRANSFER CHARACTER-SET TRANSPARENT could give garbage
- translations.
- * TRANSLATE might not work on Little Endian architectures.

-
- The following bugs in C-Kermit 8.0.200 were fixed in 8.0.201:
-
- * An obscure path through the code could cause the Unix version of
- C-Kermit to dump core during its startup sequence. This happened
- to only one person, but now it's fixed.
- * When C-Kermit 8.0 is in Kermit server mode and the client says
- "get blah", where blah (on the server) is a symlink rather than a
- real file, the server unreasonably refused to send the linked-to
- file.
- * When C-Kermit is an FTP client and says "get foo/bar" (i.e. a
- filename that includes one or more path segments), it failed to
- accept the incoming file (this happened only with GET, not MGET).
- * Array references should be case insensitive but only lowercase
- array letters were accepted.
- * SHOW VARIABLES dumped core on \v(sexpression) and \v(svalue).
- * Spurious refusals of remote directory listings if the remote
- server's date was set in the past.
- * In AIX, and maybe elsewhere too, Kermit's COPY command always
- failed with "Source and destination are the same file" when the
- destination file didn't exist.
- * The VMS version of C-Kermit did not work in Batch or when SPAWN'd.
- To compound the problem, it also pretty much ignored the -B and -z
- command-line options, whose purpose is to work around such
- problems.
- * C-Kermit 8.0 could not be built on IRIX 5.x.
- * The C-Kermit 8.0 build for QNX6 said it was an "(unknown
- version)".

-2. SSH AND HTTP
-
- 2.1. SSH Connections
-
- This section does not apply to [166]Kermit 95 2.0, which has its
- own built-in SSH client, which is documented [167]SEPARATELY.
-
- On most UNIX platforms, C-Kermit can make SSH (Secure SHell)
- connection by running the external SSH command or program through its
- pseudoterminal interface. The command is:
-
- SSH text
- Tells Kermit to start the external SSH client, passing the
- given text to it on the command line. Normally the text is just
- the hostname, but it can be anything else that is acceptable to
- the ssh client. If the command succeeds, the connection is made
- and Kermit automatically enters CONNECT (terminal) mode. You
- can use the SSH command to make a connection to any host that
- has an SSH server.
-
- Kermit's SSH command gives you all the features of Kermit on an SSH
- connection: command language, file transfer, character-set
- translation, scripting, and all the rest. By default, C-Kermit invokes
- SSH with "-e none", which disables the ssh escape character and makes
- the connection transparent for purposes of file transfer. You can,
- however, change the SSH invocation to whatever else you might need (an
- explicit path, additional command-line arguments, etc) with:
-
- SET SSH COMMAND text
- Specifies the system command that Kermit's SSH command should
- use to invoke the external SSH client. Use this command to
- supply a specific path or alternative name, or to include
- different or more command-line options.
-
- In most cases, these connections work quite well. They can be scripted
- like any other connection, and file transfer goes as fast as, or
- faster than, on a regular Telnet connection. In some cases, however,
- the underlying pseudoterminal driver is a limiting factor, resulting
- in slow or failed file transfers. Sometimes you can work around such
- problems by reducing the Kermit packet length. Note that Kermit does
- not consider SSH connections to be reliable, so it does not offer to
- use streaming in Kermit protocol transfers (but you can force it with
- SET RELIABLE or SET STREAMING if you wish).
-
- The SSH command is like the TELNET command: it enters CONNECT mode
- automatically when the connection is made. Therefore, to script an SSH
- connection, use:
-
- set host /pty ssh -e none [ other-options ] host
- if fail ...
-
- to make the connection.
-
- Here's a sequence that can be used to make a connection to a given
- host using Telnet if the host accepts it, otherwise SSH:
-
- if not defined \%1 exit 1 Usage: \%0 host
- set quiet on
- set host \%1 23 /telnet
- if fail {
- set host /pty ssh -l \m(user) -e none \%1
- if fail exit 1 \%1: Telnet and SSH both fail
- echo SSH connection to \%1 successful
- } else {
- echo Telnet connection to \%1 successful
- }
-
- In SSH v2, it is possible to make an SSH connection direct to a Kermit
- server system if the host administrator has configured the SSH server
- to allow this; [168]CLICK HERE for details.
-
- Since Kermit uses external ssh client software, and since there are
- different ssh clients (and different releases of each one), the exact
- command to be used to make an SSH/Kermit connection can vary. Here is
- the command for the OpenSSH 3.0.2p1 client:
-
-set host /pipe ssh -e none [ -l username ] -T -s hostname kermit
-
- Example:
-
-set host /pipe ssh -e none -l olga -T -s hq.xyzcorp.com kermit
-
- The SSH client might or might not prompt you for a password or other
- information before it makes the connection; this depends on your SSH
- configuration (your public and private keys, your authorized hosts
- file, etc). Here's a brief synopsis of the OpenSSH client command
- syntax ("man ssh" for details):
-
- -e none
- This tells the SSH client to use no escape character. Since we
- will be transferring files across the connection, we don't want
- the connection to suddenly block because some character in the
- data.
-
- -l username
- This is the username on the remote host. You can omit the -l
- option and its argument if your local and remote usernames are
- the same. If they are different, you must supply the remote
- username.
-
- -T
- This tells the SSH client to tell the SSH server not to
- allocate a pseudoterminal. We are not making a terminal
- connection, we don't need a terminal, and in fact if a terminal
- were allocated on the remote end, the connection would not
- work.
-
- -s ... kermit
- This tells the SSH client to tell the SSH server to start the
- specified subsystem ("kermit") once the connection is made. The
- subsystem name comes after the hostname.
-
- hostname
- The IP host name or address of the desired host.
-
- You might want to include other or additional ssh command-line
- options; "man ssh" explains what they are. Here are some examples for
- the OpenSSH 3.0.2p1 client:
-
- -oClearAllForwardings yes
- -oForwardAgent no
- -oForwardX11 no
- -oFallbackToRsh no
- These ensure that a secure connection is used and that the
- connection used for file transfer is not also used for
- forwarding other things that might be specified in the
- ssh_config file.
-
- -oProtocol 2
- (i.e. SSH v2) Ensures that the negotiated protocol supports
- subsystems.
-
- Once you have an SSH connection to a Kermit server, it's just like any
- other connection to a Kermit server (and very similar to a connection
- to an FTP server). You give the client file transfer and management
- commands for the server, and the server executes them. Of course you
- can also give the client any other commands you wish.

-
- 2.2. HTTP Connections
-
- Hypertext Transfer Protocol, or HTTP, is the application protocol of
- the World Wide Web (WWW), used between Web browsers (clients) and Web
- servers. It allows a client to get files from websites, upload files
- to websites, delete files from websites, get information about website
- directories and files, and interact with server-side CGI scripts.
- C-Kermit includes an HTTP client capable of both clear-text and secure
- HTTP connections, that can do all these tasks and can be automated
- through the Kermit scripting language.
-
- Although C-Kermit 7.0 could make HTTP connections to Web servers, it
- could do so only when no other connection was open, and the procedure
- was somewhat awkward. C-Kermit 8.0 improves matters by:
-
- * Allowing an HTTP connection to be open at the same time as a
- regular SET LINE or SET HOST connection, and also at the same time
- as an FTP connection ([171]Section 3);
- * Upgrading the HTTP protocol level from 1.0 to 1.1, thus allowing
- for persistent connections, in which a series of commands can be
- sent on the same connection, rather than only one as in HTTP 1.0
- (and C-Kermit 7.0);
- * Providing for "one-shot" URL-driven HTTP operations such as GET or
- PUT.
- * Providing a distinct HTTP command-line personality.
-
- Persistent HTTP connections are managed with the following commands:
-
- HTTP [ switches ] OPEN [ security-options ] host-or-url [ port ]
- Opens a persistent connection to the specified host (IP host
- name or address) on the specified port. If any switches
- (options, listed in the next section) are included, their
- values are saved and used for all subsequent HTTP action
- commands on the same connection. If no port is specified, HTTP
- (80) is used. A Uniform Resource Locator (URL, [172]RFC 1738)
- can be given instead of a hostname (or address) and port (but
- the URL can not include a directory/file path). The security
- options are explained [173]below. The HTTP OPEN command
- replaces the C-Kermit 7.0 SET HOST hostname HTTP command, which
- no longer works with HTTP GET and related commands.
-
- HTTP CLOSE
- Closes any open HTTP connection and clears any saved switch
- values.
-
- A URL starts with a protocol name, which must be http or https in this
- case; optionally includes a username and password; and must contain a
- host name or address:
-
- protocol://[user[.password]]@host[:port][URI]
-
- HTTP is Hypertext Transfer Protocol. HTTPS is the secure (SSL/TLS)
- version of HTTP. The TCP service port is derived from the protocol
- prefix (so normally the ":port" field is omitted). Thus the URL
- protocol name specifies a default TCP service port and the URL user
- and password fields can take the place of the /USER and /PASSWORD
- switches ([174]Section 2.2.1). The optional URI is a "compact string
- of characters for identifying an abstract or physical resource"
- ([175]RFC 2396), such as a file. It must begin with a slash (/); if
- the URI is omitted, "/" is supplied. Examples:
-
- http open http://www.columbia.edu/
- Equivalent to http open www.columbia.edu or http open
- www.columbia.edu http.
-
- http open https://olga.secret@www1.xyzcorp.com/
- Equivalent to http /user:olga /pass:secret open
- www1.xyzcorp.com https.
-
- Persistence is accomplished unilaterally by C-Kermit 8.0. An HTTP 1.0
- server closes the connection after each action. Although HTTP 1.1
- allows multiple actions on the same connection, an HTTP 1.1 server
- tends to close the connection if it is idle for more than a few
- seconds, to defend itself against denial-of-service attacks. But when
- you use Kermit's HTTP OPEN command to create a connection, Kermit
- reopens it automatically (if necessary) for each HTTP action until you
- close it with HTTP CLOSE, regardless of the server's HTTP protocol
- version, or how many times it closes the connection.
-
- Firewalls can be negotiated through proxies with the following
- commands:
-
- SET TCP HTTP-PROXY [ host[:port] ]
- If a host (by hostname or IP address) is specified, Kermit uses
- it as a proxy server when attempting outgoing TCP connections
- -- not only HTTP connections, but all TCP/IP connections,
- Telnet and FTP included. This allows Kermit to adapt to the
- HTTP firewall penetration method (as opposed to other methods
- such as SOCKS4). If no hostname or ip-address is specified, any
- previously specified Proxy server is removed. If no port number
- is specified, the "http" service is used. This command must be
- given before the HTTP OPEN command if a proxy is to be used or
- canceled.
-
- HTTP [ switches ] CONNECT host[:port]
- Instructs the HTTP server to act as a proxy, establishing a
- connection to the specified host (IP hostname or address) on
- the given port (80 = HTTP by default) and to redirect all data
- transmitted between Kermit and itself to the given host for the
- life of the connection. This command is to be used only for
- debugging HTTP proxy connections. If a proxy connection is
- required, instruct Kermit to use the proxy with the SET TCP
- HTTP-PROXY command.
-
- 2.2.1. HTTP Command Switches
-
- HTTP switches, like all other switches, are optional. When HTTP
- switches are included with the HTTP OPEN command, they apply
- automatically to this and all subsequent HTTP actions (GET, PUT, ...)
- on the same connection until an HTTP CLOSE command is given. So if you
- include switches (or the equivalent URL fields, such as user and
- password) in the HTTP OPEN command, you can omit them from subsequent
- commands on the same connection. If the connection has closed since
- your last command, it is automatically reopened with the same options.
-
- If you include switches with an HTTP action command (such as GET or
- PUT), they apply only to that command.
-
- /USER:name
- To be used in case a page requires a username for access. The
- username is sent with page requests. If it is given with the
- OPEN command it is saved until needed. If a username is
- included in a URL, it overrides the username given in the
- switch. CAUTION: Username and password (and all other
- information, including credit card numbers and other material
- that you might prefer to protect from public view) are sent
- across the network in clear text on regular HTTP connections,
- but authentication is performed securely on HTTPS connections.
-
- /PASSWORD:text
- To be used in case a web page requires a password for access.
- The password is sent with page requests. If it is given with
- the OPEN command it is saved until needed. If a password is
- given in a URL, it overrides the one given here. CAUTION: (same
- as for /USER:).
-
- /AGENT:user-agent
- Identifies the client to the server. Overrides the default
- agent string, which is "C-Kermit" (for C-Kermit) or "Kermit-95"
- (for Kermit 95).
-
- /ARRAY:array-designator
- Tells Kermit to store the response headers in the given array,
- one line per element. The array need not be declared in
- advance. Example: /array:&a.
-
- /TOSCREEN
- Tells Kermit to display any response text on the screen. It
- applies independently of the output file specification; thus it
- is possible to have the server response go to the screen, a
- file, both, or neither.
-
- /HEADER:header-item(s)
- Used for specifying any optional headers to be sent with HTTP
- requests.
-
- /HEADER:tag:value
-
- To send more than one header, use braces for grouping:
-
- /HEADER:{{tag:value}{tag:value}...}
-
- For a list of valid tags and value formats see [176]RFC 2616,
- "Hypertext Transfer Protocol -- HTTP/1.1". A maximum of eight
- headers may be specified.
-
- 2.2.2. HTTP Action Commands
-
- HTTP actions can occur within a persistent connection, or they can be
- self-contained ("connectionless"). A persistent HTTP connection begins
- with an HTTP OPEN command, followed by zero or more HTTP action
- commands, and is terminated with an HTTP CLOSE command:
-
- http open www.columbia.edu
- if failure stop 1 HTTP OPEN failed: \v(http_message)
- http get kermit/index.html
- if failure stop 1 HTTP GET failed: \v(http_message)
- (more actions possible here...)
- http close
-
- A self-contained HTTP action occurs when a URL is given instead of a
- remote file name to an HTTP action command. In this case, Kermit makes
- the HTTP connection, takes the action, and then closes the connection.
- If an HTTP connection was already open, it is closed silently and
- automatically.
-
- http get http://www.columbia.edu/kermit/index.html
-
- Kermit's HTTP action commands are as follows. Switches may be included
- with any of these to override switch (or default) values given in the
- HTTP OPEN command.
-
- HTTP [ switches ] GET remote-filename [ local-filename ]
- Retrieves the named file from the server specified in the most
- recent HTTP OPEN command for which a corresponding HTTP CLOSE
- command has not been given. The filename may not include
- wildcards (HTTP protocol does not support them). If no HTTP
- OPEN command is in effect, this form of the HTTP GET command
- fails. The default local filename is the same as the remote
- name, but with any pathname stripped. For example, the command
- http get kermit/index.html stores the file in the current local
- directory as index.html. If the /HEADERS: switch is included,
- information about the file is also stored in the specified
- array (explained in [177]Section 2.2.3). All files are
- transferred in binary mode. HTTP does not provide for
- record-format or character-set conversion.
-
- HTTP [ switches ] GET url [ local-filename ]
- When HTTP GET is given a URL rather than a filename, Kermit
- opens a connection to the designated server (closing any
- previously open HTTP connection), gets the file, and then
- closes the connection. If the URL does not include a filename,
- index.html is supplied. This is the self-contained one-step
- "connectionless" method for getting a file from a Web server.
- The data is not interpreted; HTTP GET is like "lynx -source"
- rather than "lynx -dump".
-
- In the remaining HTTP action commands, the distinction between a
- remote filename and a URL are the same as in the HTTP GET command.
-
- HTTP [ switches ] HEAD remote-filename-or-url [ local-filename ]
- Like GET except without actually getting the file; instead it
- retrieves only the headers. If the /ARRAY: or /TOSCREEN switch
- is included, there is no default local output filename but you
- can still specify one. If neither of these switches is
- included, the default local filename is the same as the remote
- filename, but with any path stripped and with ".head" appended.
- The HEAD command can be used in a script with the /ARRAY:
- switch to retrieve information about the requested resource to
- determine whether the resource should actually be retrieved
- with a subsequent GET request.
-
- HTTP [ switches ] INDEX remote-directory-or-url [ local-filename ]
- Asks the server to send a listing of the files in the given
- server directory. This command is not supported by most Web
- servers. Even when it is supported, there is no standard format
- for the listing.
-
- HTTP [ switches ] POST [ /MIME-TYPE:type ] source-file
- remote-path-or-url [ result-file ]
- Sends data to a process running on the remote host; the result
- is usually an HTML file but could be anything. The data to be
- posted must be read from a local file (the source-file). If a
- result file is specified, Kermit stores the server's response
- in it.
-
- HTTP [ switches ] PUT [ MIME-TYPE:type ] local-file [
- remote-file-or-url [ result-file ] ]
- Uploads a local file to the server. Only the name of a single
- file can be given; wildcards (and group transfers) are not
- supported by HTTP protocol. If no remote filename is given, the
- file is sent with the same name as the local file, but with any
- pathname stripped.
-
- HTTP [ switches ] DELETE remote-file-or-url [ local-result-file ]
- Asks the server to delete the specified single file. If a
- result file is specified, it will contain any response data
- returned by the server.
-
- Note the limitations of HTTP protocol compared to (say) FTP or Kermit.
- There is no command for changing directories, no standard way to get
- file or directory lists, no way to transfer file groups by using
- wildcard notation, etc, and therefore no good way to (say) fetch all
- pages, descend through subdirectories, perform automatic updates, etc.
- There is no assurrance a connection will stay open and, as noted,
- there is no provision for data conversion between unlike platforms.
- The data's MIME headers can be used for postprocessing.
-
- 2.2.3. HTTP Headers
-
- Each HTTP request and response contains a set of name/value pairs
- called headers. HTTP headers are specified in [178]RFC 2616. For
- example, an HTTP GET request for /index.html on www.columbia.edu
- contains the following headers:
-
- GET /index.html HTTP/1.1
- Host: www.columbia.edu:80
- User-agent: C-Kermit 8.0
- Authorization: Basic base64-encoded-username-password
-
- These might be followed by any others specified with a /HEADERS:
- switch:
-
- Accept: image/gif, image/x-xbitmap, image/jpeg, *.*
- Accept-Encoding: gzip
- Accept-Language: en
- Accept-Charset: iso-8859-1,utf-8
- Cookie: cookie-data
-
- The server sends back a short report about the file prior to sending
- the file contents. Example:
-
- HTTP/1.1 200 OK
- Date: Fri, 24 Aug 2001 21:09:39 GMT
- Server: Apache/1.3.4 (Unix)
- Last-Modified: Mon, 06 Aug 2001 21:16:13 GMT
- ETag: "1fa137-10d7-3b6f091d"
- Accept-Ranges: bytes
- Content-Length: 4311
- Content-Type: text/html
-
- If you want to have this information available to a Kermit script you
- can use the /ARRAY switch to have Kermit put it in array, one line per
- array element. Example:
-
- set exit warning off
- http open www.columbia.edu
- if fail exit 1 Can't reach server
- http /array:&a get /index.html
- if fail exit 1 Can't get file
- echo Header lines: \fdim(&a)
- for \%i 1 \fdim(&a) 1 {
- echo \%i. \&a[\%i]
- }
-
- Note that the "Date:" item is the current date and time; the
- "Last-Modifed:" item is the file's modification date and time. An
- example showing how to use this information is presented in
- [179]Section 8.13.7.
-
- 2.2.4. Secure HTTP Connections
-
- SSL/TLS (Secure Sockets Layer / Transport Layer Security) is the
- protocol used to secure HTTP, SMTP, and other Internet applications.
- See the [180]C-Kermit Reference Section 5.4 for an introduction to
- SSL/TLS. To make a secure HTTP connection, you need:
-
- 1. A secure client (a version of C-Kermit or Kermit 95 with SSL/TLS
- security built in). Type "check ssl" at the Kermit prompt to make
- sure you have it.
- 2. A secure server to connect to.
- 3. The CA Root Certificate used to authenticate the server to the
- client. (see [181]Section 15 of the security reference for an
- introduction to certificates).
-
- And you must make a connection to the secure HTTP port: service name
- HTTPS, port number 443 (as opposed to service HTTP, port 80). You can
- also make secure connections to other ports by including the /TLS or
- /SSL switch with the HTTP OPEN command, if the host supports SSL/TLS
- on the given port:
-
- The quality of the SSL/TLS connection depends on the cipher suite.
- There are several possibilities:
-
- Anonymous cipher suite:
- If an anonymous cipher suite is negotiated, the connection is
- encrypted but there is no authentication. This connection is
- subject to a Man-In-The-Middle (MITM) attack.
-
- X.509 certificate on the server:
- When you connect to certain secure servers, an X.509
- certificate is returned. This certificate is issued to a
- special hostname, something like www1.xyzcorp.com or
- wwws.xyzcorp.com (rather than the normal www.xyzcorp.com). It
- is signed by the host's Certificate Authority (CA). If the host
- certificate is configured on the client, it can be used to
- verify the certificate received from the server. If the
- certificate it verified as authentic, a check is made to ensure
- it has not expired and it was issued to the host you were
- attempting to connect to. If you had asked to connect to (say)
- www.xyzcorp.com but were given a certificate for
- www1.xyzcorp.com, you would be prompted for permission to
- continue.
-
- If the verification succeeded, the connection would be
- encrypted with one-way (server-to-client) authentication. This
- connection is not subject to a MITM attack.
-
- If a username and password are transmitted over this
- connection, they are not subject to interception. However, the
- standard risks associated with passing the password to the host
- for verification apply; for example, if the host has been
- compromised, the password will be compromised.
-
- X.509 client certificate:
- If a connection has been established with an X.509 server
- certificate, the server can ask the client to send a
- certificate of its own. This certificate must be verified
- against a CA Root certificate. The certificate itself (or
- subject info from the certificate) is used to determine the
- authorization for the client, and if successful, the username
- and password need not be sent to the server.
-
- Kerberos 5:
- Instead of using X.509 certifcates, Kerberos 5 can be used to
- perform the authentication and key exchange. In this situation,
- there is mutual authentication between the client and server.
- The Kerberos 5 principal is used by the server to look up the
- appropriate authorization data. There is no need to send
- username and password.
-
- An HTTP connection is made with the HTTP OPEN command:
-
- HTTP [ switches ] OPEN [ { /SSL, /TLS } ] host [ port ]
- If /SSL or /TLS switches are included (these are synonyms), or
- if the service is HTTPS or the port is 443, a secure connection
- is attempted using the current authentication settings; see
- HELP SET AUTHENTICATION for details ([182]Section 6.2 of the
- security reference). If the no /SSL or /TLS switch is included
- but the port is 443 or the service is HTTPS, a secure
- connection is attempted. If an /SSL or /TLS switch is included
- but a port is not specified, an SSL/TLS connection is attempted
- on the default port (80).
-
- Certificates are covered in the separate [183]Kermit Security
- Reference for C-Kermit 8.0. You should let Kermit know to verify
- certificates with the SET AUTHENTICATION TLS command. For example:
-
- SET AUTHENTICATION TLS CRL-DIR directory
- Specifies a directory that contains certificate revocation
- files where each file is named by the hash of the certificate
- that has been revoked.
-
- SET AUTHENTICATION TLS CRL-FILE filename
- Specifies a file that contains a list of certificate
- revocations.
-
- SET AUTHENTICATION TLS VERIFY-DIR directory
- Specifies a directory that contains root CA certificate files
- used to verify the certificate chains presented by the peer.
- Each file is named by a hash of the certificate.
-
- SET AUTHENTICATION TLS VERIFY-FILE filename
- Specifies a file that contains root CA certificates to be used
- for verifying certificate chains.
-
- SET AUTHENTICATION TLS VERIFY OFF
- Tells Kermit not to require a certificate and accept any
- certificate that is presented regardless of whether it is
- valid.
-
- There are many other options; see the security document for details.
-
- Now suppose you need need to fetch the file denoted by the following
- URL:
-
- https://myuserid:mypassword@wwws.xyzcorp.com/clients/info/secret.html
-
- Once you have set up the handling of certificates as desired, you can
- use the following Kermit commands:
-
- http /user:myuserid /password:mypassword open www1.xyzcorp.com https
- if success {
- http get /clients/info/secret.html
- http close
- }
-
- As another example, let's say that you have a web form you need to
- populate with three fields: red,white and blue.
-
- <FORM ACTION="http://www.xyzcorp.com/cgi-bin/form.cgi" METHOD="POST">
- <INPUT NAME="Red">
- <INPUT NAME="White">
- <INPUT NAME="Blue">
- </FORM>
-
- You can handle this with the HTTP POST command. The data to be posted
- is stored in the local file data.txt.
-
- Red=seven stripes&White=six stripes&Blue=fifty stars
-
- and the response from the server will be stored into response.txt.
-
- http open www.xyzcorp.com http
- if success {
- http /array:c post data.txt /cgi-bin/form.cgi response.txt
- http close
- }
-
- In this scenario, the Common Gateway Interface (CGI) sends a response
- whether it succeeds or fails in a script-dependent manner. The script
- can either report success and enclose the response data; or it might
- send a 302 Found error which indicates that the "Location:" header
- should be used to determine the URL at which the data can be found.
-
- 2.2.5. HTTP Variables
-
- \v(http_code)
- The HTTP protocol code number of the most recent server reply,
- e.g. 404 for "not found".
-
- \v(http_connected)
- 1 when an HTTP connection is open, 0 when there is no HTTP
- connection.
-
- \v(http_host)
- If an HTTP connection is open, the hostname:port, e.g.
- www.columbia.edu:80; otherwise, empty.
-
- \v(http_message)
- Server error message, if any, from most recent HTTP command.
-
- \v(http_security)
- A list of the security parameters and values for the current
- connection, if any. Empty if the connection is not to a secure
- server, or there is no connection.
-
- To display all the HTTP variables at once, type SHOW VAR HTTP:
-
- C-Kermit> http open www.columbia.edu
- C-Kermit> http get lkjlkjlkjlkj
- C-Kermit> sho var http
- \v(http_code) = 404
- \v(http_connected) = 1
- \v(http_host) = www.columbia.edu:80
- \v(http_message) = Not Found
- \v(http_security) = NULL
- C-Kermit>
-
- 2.2.6. The HTTP Command-Line Personality
-
- If you invoke C-Kermit with the name "http" or "https", you can use a
- special set of HTTP-specific command-line options. You can do this by
- creating a symbolic linke "http" or "https" to the C-Kermit 8.0
- executable, or by having a separate copy of it called "http" or
- "https". Here's the usage message ("http -h"):
-
- Usage: ./http host [ options... ]
- -h This message.
- -d Debug to debug.log.
- -S Stay (issue command prompt when done).
- -Y Do not execute Kermit initialization file.
- -q Quiet (suppress most messages).
- -u name Username.
- -P password Password.
- -g pathname Get remote pathname.
- -p pathname Put remote pathname.
- -H pathname Head remote pathname.
- -l pathname Local path for -g, -p, and -H.
- -z opt[=value] Security options...
- cert=file Client certificate file
- certsok Accept all certificates
- key=file Client private key file
- secure Use SSL
- verify=n 0 = none, 1 = peer , 2 = certificate required
-
- The "host" argument is the name of a Web host, e.g. www.columbia.edu.
- The action options are -p, -g, and -H. If you give an action option,
- Kermit does the action and then exits. If you give a host without an
- action option, Kermit makes an HTTP connection to the host and then
- gives you the C-Kermit prompt. Here's a simple example that fetches a
- publicly readable Web page:
-
- http www.columbia.edu -g kermit/index.html
-
- If you need to access a website for which a username and password are
- required, you can supply them on the command line with -u and -P. If
- you include a username but omit the password, Kermit prompts you for
- it:
-
- http www.columbia.edu -u olga -p kermit/index.html -l index.html
- Password:
-
- Note that when PUT'ing files to websites, you have to supply both the
- -p (remote pathname) and -l (local path) options.
-
- If your version of Kermit is built with SSL/TLS security, you can also
- use the -z option to make secure HTTP (https) connections.
-
- Finally, as noted in [184]Section 16, you can also give a URL instead
- of a host name and options.

- 3.11. [199]Advanced FTP Protocol Features
-
- Earlier versions of C-Kermit and K95 included an FTP command, but it
- simply invoked an external FTP client. Now, by popular demand, Kermit
- includes its own built-in FTP client that offers the following
- advantages over traditional FTP clients (and its previous interface to
- them):
-
- * Any of Kermit's built-in [200]security methods can be used to
- establish and conduct secure FTP sessions with [201]FTP servers
- that support these methods. (Security modules can be subject to
- export restrictions.)
- * Kermit's FTP client uses "passive mode" by default to avoid
- blockage by firewalls and network address translators. Of course
- active mode can be chosen too when needed.
- * [202]Character sets can be translated as part of the transfer
- process even when the FTP server does not support character-set
- translation, including to/from the new Internet standard
- international character set, [203]Unicode UTF-8. This includes
- both the file's name and (for text files only) its contents.
- * All of C-Kermit's [204]file-selection mechanisms are available:
- size, date, name patterns and lists, exception lists, etc.
- * [205]Atomic file movement capabilities are provided (delete, move,
- or rename files automatically after successful transfer).
- * The correct file type, "ascii" (i.e. text) or binary, is chosen
- automatically for each file (explained in [206]Section 4), and any
- mixture of text and binary files can be sent in a single
- operation, even across platforms.
- * Update mode ("don't bother transferring files that didn't change
- since last time") and recovery (resumption of an interrupted
- transfer from the point of failure) are available in both
- directions.
- * When uploading files from UNIX to UNIX, the file's permissions can
- be preserved if desired.
- * Recursive directory-tree PUTs are supported between any two
- platforms that have tree-structured file systems. Recursive GETs
- are supported between like platforms if the server cooperates and
- between like or unlike platforms if the server supports MLSD
- ([207]Section 3.11).
- * When receiving files, all of Kermit's file collision actions are
- available: backup, update, refuse, rename, etc.
- * Multi-file transfers can be interrupted on a per-file basis,
- automatically skipping to the next file.
- * FTP sessions are [208]fully scriptable.
- * An entire FTP session (connect, login, CD, upload or download,
- logout) can be specified on the command line without using a
- script.
- * All of Kermit's logging options and formats are available to keep
- an accurate and complete record of each connection and file
- transfer, and to aid in troubleshooting.
- * All of Kermit's file-transfer display options are available
- (fullscreen, brief, CRT, serial, none).
-
- And best of all:
- * Kermit doesn't give you those annoying per-file prompts every time
- you start a multi-file transfer without remembering to give a
- "prompt" command first :-).

- _________________________________________________________________
-
- 3.1. Making and Managing FTP Connections
-
- Each copy of Kermit can have one FTP connection open at a time. FTP
- connections are independent of regular terminal connections; a
- terminal connection (serial or network via SET LINE, DIAL, SET HOST,
- TELNET, etc) may be, but need not be, open at the same time as an FTP
- connection, and terminal connections can also be closed, and new
- connections opened, without interfering with the FTP connection (and
- vice versa). Thus, for example, Kermit can have an FTP connection and
- a TELNET connection open to the same host simultaneously, using the
- TELNET connection (e.g.) to send mail or take other desired actions as
- various FTP actions complete. Of course, each copy of Kermit can do
- only one thing at a time, so it can't (for example) transfer a file
- with FTP and another file with Kermit protocol simultaneously.
-
- A Kermit FTP session can be established by [215]command-line options,
- by [216]URL, or by [217]interactive commands.
-
- 3.1.1. Kermit Command-Line Options for FTP
-
- The new command-line option '-9' (sorry, we're out of letters) can be
- used when starting C-Kermit, telling it to make an FTP connection:
-
- kermit -9 hostname
-
- or if a non-default FTP port is needed:
-
- kermit -9 hostname:port
-
- You can also specify the username on the command line with the -M ("My
- User ID") option that was already there for other connection types:
-
- kermit -9 hostname -M olga
-
- If you specify the username on the command line, Kermit uses it when
- making the connection and does not prompt you for it (but it does
- prompt you for the password if one is required).
-
- Once the connection is made, you get the regular Kermit prompt, and
- can give interactive commands such as the ones described below. When
- you give a BYE command, Kermit closes the session and exits, just as a
- regular FTP client would do. If you don't want Kermit to exit when you
- give a BYE command, include the -S ("Stay") option on the command
- line.
-
- Other Kermit command-line options that are not specific to non-FTP
- connections should affect the FTP session in the expected ways; for
- example, -i and -T force binary and text mode transfers, respectively.
-
- File transfers can not be initiated on the "kermit -9" command line;
- for that you need to use Kermit's FTP personality (next section) or
- you can use URLs ([218]Section 3.1.3).
- _________________________________________________________________
-
- 3.1.2. The FTP Command-Line Personality
-
- If you want to replace your regular FTP client with C-Kermit, you can
- make a link called "ftp" to the C-Kermit binary (or you can store a
- copy of the C-Kermit binary under the name "ftp"). When C-Kermit is
- invoked with a program name of "ftp" (or "FTP", case doesn't matter),
- it assumes the command-line personality of the regular FTP client:
-
- ftp [ options ] hostname [ port ]
-
- In this case the options are like those of a regular FTP client:
-
- -d Debug: enables debug messages and creates a debug.log file.
- -n No autologin: Kermit should not send your user ID automatically.
- -t Packet trace: accepted but is treated the same as -d.
- -v Verbose: accepted but ignored (operation is verbose by default).
- -i Not interactive: accepted but ignored.
-
- and the hostname can also be a URL (explained in [219]Section 3.1.3).
- To specify a non-default TCP port for the FTP server, include the port
- number or name after the hostname.
-
- There are also some bonus options that allow you to execute an entire
- FTP session from the shell command line, as long as you don't include
- the -n option. These are not available with regular FTP clients, and
- at least one of these options (-g) conflicts with UNIX ftp (where -g
- means "no globbing", which does not apply to Kermit), and some of them
- (like the options above) also conflict with regular Kermit
- command-line options:
-
- -m mode = "passive" (default) or "active"
- -Y Don't execute the Kermit initialization file [1]
- -q Quiet, suppresses all but error messages [1]
- -S Stay, don't exit automatically [1]
- -A Autologin anonymously [2]
- -u name Username for autologin [2] (synonym: -M [1])
- -P password Password for autologin (see cautions below) [2]
- -D directory cd after autologin [2]
- -b Binary mode [2]
- -a Text ("ascii") mode [2] (synonym: -T [1])
- -R Recursive (works with -p) [4]
- -p files Files to put (upload) after autologin [2] (synonym: -s [1])
- -g files Files to get (download) after autologin [3]
-
- [1] Same as Kermit, not available in regular FTP clients.
- [2] Conflicts with Kermit, not available in regular FTP clients.
- [3] Same as Kermit, conflicts with regular FTP clients.
- [4] Conflicts with Kermit, available in some FTP clients.
-
- Fancier options such as restart, character-set translation, filename
- collision selection, automatic move/rename/delete, etc, are not
- available from the command line; for these you can use the commands
- described in the following sections. The -R option might also work
- with -g (GET) but that depends on the server.
-
- The following security options are also available, explained in
- [220]Section 3.2:
-
- -k realm Kerberos 4 realm [4]
- -f Kerberos 5 credentials forwarding [4]
- -x autoencryption mode [4]
- -c cipher SRP cipher type [4]
- -H hash SRP encryption hash [4]
- -z option Security options [4]
-
- If you include -A or specify a name of "anonymous" or "ftp", you are
- logged in anonymously and, in the absence of -P, Kermit automatically
- supplies a password of "user@host", where "user" is your local user
- ID, and "host" is the hostname of the computer where Kermit is
- running. If you do not include -p or -g, Kermit enters command mode so
- you can type commands or execute them from a script.
-
- If you include -p or -g, Kermit attempts to transfer the specified
- files and then exits automatically at the end of the transfer unless
- you also included -S (Stay). It uses the "brief" file transfer display
- (one line per file) unless you include the -q option to suppress it.
-
- When uploading files with -p, Kermit switches automatically between
- text and binary mode for each file.
-
- When downloading, you can either specify a particular mode (text or
- binary) to be used for all the files, or you can let Kermit select the
- type for each file automatically, based on its name (see [221]Sections
- 3.5 and [222]3.6 for greater detail). In UNIX be sure to quote any
- wildcard characters to prevent the shell from expanding them, as shown
- in the examples just below. Filename collisions are handled according
- Kermit's FILE COLLISION setting (if specified in your Kermit
- customization file; otherwise the default, which is BACKUP).
-
- It should go without saying that the -P option should be used with
- caution. In addition to the well-known risks of transmitting plaintext
- passwords over the Internet, in this case the password also echos to
- the screen if you type it, and can be seen in ps and w listings that
- show the user's currently active command and command-line arguments.
- Thus command-line FTP sessions are most appropriate for secure or
- anonymous connections (those that do not require passwords).
-
- Here's an example in which you download the latest C-Kermit "tarball"
- from the Columbia University FTP archive:
-
- ftp -A kermit.columbia.edu -bg kermit/archives/ckermit.tar.gz
-
- This assumes that "ftp" is a symbolic link to C-Kermit. It logs you in
- anonymously and gets the ckermit.tar.gz file in binary mode from the
- kermit/archives directory.
-
- Here's a slightly more ambitious example that illustrates CD'ing to
- the desired server directory to get a group of files in text mode (in
- this case the C-Kermit source files):
-
- ftp -A kermit.columbia.edu -D kermit/f -ag "ck[cuw]*.[cwh]" makefile
-
- In this case we CD to the kermit/f directory so we don't have to
- include it in each file specification, and we quote the ck[cuw]*.[cwh]
- specification so the shell doesn't expand it, since we have to pass it
- as-is to the server. Note also that the quotes don't go around the
- entire file list; only around each file specification that needs to be
- quoted.
-
- Here's one more example, that uploads a debug log file in binary mode
- to the Kermit incoming directory (as we might ask you to do when
- following up on a problem report):
-
- ftp -A kermit.columbia.edu -D kermit/incoming -bp debug.log
-
- In this case the -D option is required to tell the server where to put
- the incoming file.
-
- Unless the -Y option is included, your Kermit initialization file
- (.mykermrc in UNIX, K95.INI in Windows) is executed before the command
- line options, so you can set any FTP-related preferences there, as
- described in the subsequent sections.
- _________________________________________________________________
-
- 3.1.3. The FTP URL Interpreter
-
- If Kermit is invoked with either its regular personality (as "kermit")
- or its FTP personality (as "ftp"), you can also give a URL
- (Universal Resource Locator) instead of a hostname and options,
- with or without a username and password:
- ftp ftp://user:password@host/path
- ftp ftp://user@host/path
- ftp ftp://@host/path (or ftp://:@host/path)
- ftp ftp://host/path
- kermit ftp://host/path
-
- If the FTP personality is used, the service must be "ftp". In all
- cases, a hostname or address must be included. If a user is included
- but no password, you are prompted for the password. If a path
- (filename) is included:
- * If "@" is included without a user, Kermit prompts for the username
- and password.
- * If no user and no "@" are included, "anonymous" is used.
- * GET is assumed.
-
- If no path (and no action options) are included, an interactive FTP
- session is started, as in this example:
- ftp ftp://kermit.columbia.edu
-
- If a path is included, but a username is not included, "anonymous" is
- used and an appropriate user@host password is supplied automatically.
- If authentication is successful, Kermit attempts to GET the file
- indicated by the path or, if the path is the name of a directory, it
- asks the server for a directory listing. In both cases, Kermit
- disconnects from the server and exits after the operation is complete
- (unless you have included the -S option on the command line).
-
- Here's an example that gets a listing of the Kermit directory at the
- Kermit ftp site:
- ftp ftp://kermit.columbia.edu/kermit/
-
- This example gets the top-level READ.ME file from the same directory:
- ftp ftp://kermit.columbia.edu/kermit/READ.ME
-
- Here's the same example, but requesting a text-mode transfer:
- ftp -T ftp://kermit.columbia.edu/kermit/READ.ME
- This illustrates that you can mix command-line options and URLs
- if you desire.
-
- Here's an example that logs in as a (fictitious) real user to get a
- file:
- ftp ftp://olga@ftp.xyzcorp.com/resume.txt
- The password is not included, so Kermit prompts for it.
-
- This scheme allows Kermit to be used as the FTP helper of other
- applications, such as Web browsers, with all its advantages over other
- FTP clients (especially the ones that are built in to most Web
- browsers), e.g. that it can be given wildcards, and it can pick text
- and binary mode automatically for each file.
-
- HINT: suppose somebody sends you an FTP URL in email, or you see it in
- some text. If your terminal screen supports copy/paste, copy the url,
- and then at the shell prompt type "kermit", a space, and then paste
- the URL, e.g.:
-
- $ kermit ftp://alpha.greenie.net/pub/mgetty/source/1.1/mgetty1.1.27-O
-
- "$ is the shell prompt; the part you type is underlined, the rest is
- pasted in. Kermit does the rest.
- _________________________________________________________________
-
- 3.1.4. Interactive FTP Session Establishment
-
- As you read this and the following sections, bear in mind that any
- command that can be given at the prompt can also be used in a script
- program. Kermit's script programming language is the same as its
- interactive command language. [223]CLICK HERE if you would like to
- learn a bit more about script writing.
-
- An FTP session is established with the FTP OPEN command:
-
- FTP [ OPEN ] [ { /SSL, /TLS } ] hostname [ switches ] [ port ]
- Opens an FTP connection to the given host on the given port
- and, if FTP AUTOLOGIN is ON, also logs you in to the server,
- prompting for username and password if necessary. If no port is
- specified, the regular FTP protocol port (21) is used. The OPEN
- keyword is optional (unless the hostname conflicts with one of
- the FTP command keywords, which you can list by typing "ftp
- ?").
-
- The hostname can be an IP host name, numeric IP address, or if you
- have a network directory active (SET NETWORK DIRECTORY; see Chapter 6
- of [224]Using C-Kermit), an entry name in the directory. In the latter
- case, if the given hostname matches exactly one entry, the associated
- name or address is used; if it matches more than one, Kermit cycles
- through them until one is found that can be opened; if it matches
- none, then the hostname is used as-is. If a directory is active but
- you want to bypass directory lookup, include an "=" sign at the
- beginning of the hostname, and/or use a numeric IP address.
-
- When an FTP connection is opened, the default file-transfer mode is
- set to binary if the client and server platforms are alike (e.g. both
- of them are some kind of UNIX), and to text ("ascii") if they are not
- alike. This has no particular effect for uploading since Kermit
- automatically switches between text and binary mode for each file, but
- might be important for downloading. The connection is also set to
- Stream mode and File structure. Record- or page-oriented file
- transfers are not supported by C-Kermit's FTP client.
-
- The optional FTP OPEN switches are:
-
- /ANONYMOUS
- Logs you in anonymously, automatically supplying username
- "anonymous" and user@host as the password, based on your local
- user and host names.
-
- /NOLOGIN
-
- Overrides SET FTP AUTOLOGIN ON for this connection only.
-
- /USER:name
- Uses the given username to log you in, thus avoiding the Name:
- prompt.
- Overrides SET FTP AUTOLOGIN OFF for this connection only.
-
- /PASSWORD:text
- Uses the given text as your password, thus avoiding the
- Password: prompt. This switch is not recommended for use in
- script files, which would be a security risk.
-
- /ACCOUNT:text
- Uses the given text as your account (or secondary password,
- depending on the requirements of the server; most servers do
- not require or accept an account name). If an account is not
- supplied, you are not prompted for one.
-
- /PASSIVE
- Opens the connection in passive mode. Passive mode is the
- default in Kermit's FTP client, unlike in most others, since it
- works better through firewalls. The /PASSIVE and /ACTIVE
- switches apply only to the connection that is being opened, and
- do not affect the global FTP PASSIVE-MODE setting.
-
- /ACTIVE
- Opens the connection in active mode. Use this switch if the
- server does not support passive mode, or use the command SET
- FTP PASSIVE-MODE OFF.
-
- /NOINIT
- Added in C-Kermit 8.0.201. Tells C-Kermit not to send REST,
- STRU, FEAT, and MODE commands to the server when the connection
- is opened, since these have been reported to cause confusion in
- certain servers.
-
- When a username or password is missing, a prompt is issued at the
- controlling terminal and you must type the response; the response can
- not be scripted. Use the switches to avoid prompts, or one of the
- secure authentication methods described in the next section, or see
- [225]SET FTP AUTOLOGIN and the [226]FTP USER and similar commands
- described later in this section.
-
- Examples:
-
- ftp open kermit.columbia.edu /anonymous ; Open and log in anonymously
- ftp kermit.columbia.edu /anonymous ; The OPEN keyword can be omitted
- ftp xyzcorp.com ; Open and maybe prompt for username
- ftp xyzcorp.com /user:olga ; Open and log in as olga
- ftp testing.abccorp.com 449 ; Specify a special TCP port number
- ftp testing.abccorp.com /user:olaf /password:secret 449
-
- The FTP OPEN command succeeds if a connection was opened to the server
- (even if the given username and password were not valid) and fails
- otherwise (see [227]Section 3.8 for details).
-
- When your FTP session is complete, you can terminate it as follows:
-
- FTP BYE
- Closes the FTP connection if one was open. The FTP prefix can
- be omitted if no other connection is open at the same time (see
- [228]Section 3.8 for details). If a connection log is active,
- an FTP record is written to it. If Kermit was started with the
- -9 command-line option or with its FTP command-line
- personality, and the -S (Stay) option was not given, AND there
- is no other active connection, the FTP BYE command also exits,
- just as it does on a regular FTP client. Synonyms: FTP CLOSE,
- FTP QUIT (but if the FTP prefix is omitted from QUIT, this
- becomes the regular Kermit QUIT command, which is equivalent to
- EXIT; i.e. it closes the connection and exits from Kermit).
-
- The following commands can be used to achieve greater control over the
- connection and login process:
-
- SET FTP ANONYMOUS-PASSWORD text
- Allows you to choose the password text to be sent automatically
- by Kermit when you open an FTP connection with the /ANONYMOUS
- switch.
-
- SET FTP AUTOLOGIN { ON, OFF }
- If you give this command prior to opening an FTP connection, it
- controls whether Kermit tries to log you in automatically as
- part of the connection process. Normally ON, which means the
- username and password are sent automatically (and prompted for
- if they are not yet known). When OFF, FTP OPEN connects to the
- server without logging in. OFF is equivalent to the -n
- command-line option when using Kermit's FTP command-line
- personality.
-
- FTP USER name [ password [ account ] ]
- Used to log in to an FTP server to which a connection has been
- made without autologin, or when autologin failed. If the
- password is furnished on the command line, it is used;
- otherwise you are prompted for a password. An account may also
- be furnished if required by the server; it is not required by
- Kermit and is not prompted for if omitted. Synonyms: USER, FTP
- LOGIN.
-
- FTP ACCOUNT text
- Sends an account name to a server that supports accounts. If
- the server does not support accounts, an error response occurs.
- If the server does support accounts, the account is accepted if
- it is valid and rejected if it is not. The account might be
- used for charging purposes or it might be a secondary password,
- or it might be used for any other purpose, such as an access
- password for a particular disk. Servers that support accounts
- might or might not allow or require the account to be sent
- prior to login; usually it is sent after login, if at all.
- Synonym: ACCOUNT.
-
- Example:
-
-set ftp autologin off ; One thing at a time please
-ftp xyzcorp.com ; Try to make the connection
-if fail exit 1 FTP connection failed ; Check that it was made
-ftp user olga secret ; Now log in to the server
-if fail exit 1 FTP login failed ; Check that it worked
-ftp account 103896854 ; Login OK - send account
-if fail echo WARNING - FTP ACCT failed ; Warn if problem
-... ; (have session here)
-bye ; Log out and disconnect
-
- The following commands are used to control or get information about
- the FTP connection. Any particular FTP server does not necessarily
- support all of them.
-
- FTP RESET
- Terminates a user session but leaves the connection open,
- allowing a new login via FTP USER.
-
- FTP IDLE [ number ]
- Most FTP servers automatically log you out and and disconnect
- your session if there has been no activity for a certain amount
- of time. Use this command to ask the server to set its idle
- limit to the given number of seconds. Omit the number to ask
- the server to inform you of its current idle limit.
-
- FTP STATUS [ filename ]
- Asks the FTP server to send information about the current
- session. The result is a free-format report that might include
- server identification, username and login time, FTP protocol
- settings, and file-transfer statistics. If a filename is given,
- the server is supposed to send detailed information about the
- file.
-
- FTP SYSTEM
- Asks the FTP server to identify its operating system (Listed in
- Internet Assigned Numbers, Operating System Names). Examples:
- UNIX, VMS, VM/CMS, WINDOWS-NT. Unfortunately many variations
- are allowed (e.g. LINUX-2.0, LINUX-2.2, FREEBSD, ULTRIX, etc,
- instead of UNIX; WINDOWS-NT-3, WINDOWS-NT-3.5, WINDOWS-NT-3.51,
- WINDOWS-NT-4, etc). The report might also include other
- information like "Type L8", "Type I", or "Type A", indicating
- the file-transfer mode.
-
- FTP HELP [ keyword [ keyword [ ... ] ]
- Asks the server to list the commands it supports. The response
- is usually cryptic, listing FTP command mnemonics, not the
- commands used by the client (since the server has no way of
- knowing anything about the client's user interface). For
- example, the PUT command is STOR in FTP protocol. If a keyword
- is given, which should be an FTP protocol command,
- slightly-more- detailed help is given about the corresponding
- command (if the FTP server supports this feature). Examples:
- "ftp help", "ftp help stor".
-
- FTP SITE text
- (Advanced) Sends an FTP SITE (site-specific) command. Usually
- this means that the FTP server is asked to run an external
- command with the given arguments. You might be able to find out
- what SITE commands are available by sending "ftp help site" to
- the server, but in general the availability of and response to
- SITE commands is (not surprisingly) site specific.
-
- FTP QUOTE text
- (Advanced) Sends an FTP command in FTP protocol format. Use
- this command to send commands to the server that the FTP client
- might not know about.
-
- SHOW FTP
- Lists client (Kermit) FTP settings and information. Also SHOW
- CONNECTION, SHOW COMMUNICATIONS.
-
- HELP FTP [ keyword ]
- Asks Kermit to list and describe its built-in FTP commands.
-
- HELP SET FTP [ keyword ]
- Asks Kermit to list and describe its built-in SET FTP commands.

- 3.2. Making Secure FTP Connections
-
- Also see: [233]Accessing IBM Information Exchange with Kermit.
-
- In the previous section, you can see several examples of traditional
- insecure authentication: username and password sent across the network
- in clear text. Of course this is bad practice on at least two counts:
- (1) storing passwords in files (such as script files) gives access to
- the target systems to anybody who can obtain read access to your
- scripts; and (2) sending this information over the network leaves it
- open to interception by network sniffers or compromised hosts.
-
- Because of the increasing need for security on the Internet, FTP
- servers are beginning to appear that offer secure forms of
- authentication, in which no information is sent over the network that
- would allow anyone who intercepts it to usurp your identity and gain
- your access rights.
-
- Kermit provides an equivalent form of FTP security for each type of
- IETF standard security implemented in Telnet. These include
- GSSAPI-KERBEROS5, KERBEROS4, Secure Remote Password (SRP), and
- Transport Layer Security (SSL and TLS). It does not presently include
- SSL tunneling nor any form of SSH v1 or v2. When Kermit is built with
- the necessary libraries, secure FTP connections are attempted by
- default, in which all connections are authenticated and the command
- and data channels are private.
-
- The use of authentication and encryption for FTP connections can be
- adjusted with the commands listed below, which are available only if
- your version of Kermit was built with the corresponding security
- options and libraries:
-
- SET FTP AUTHTYPE { AUTOMATIC, GSSAPI-KRB5, KERBEROS4, SRP, SSL, TLS }
- Specifies an ordered list of authentication methods to be
- attempted when AUTOAUTHENTICATION is ON. The default list is:
- GSSAPI-KRB5, SRP, KERBEROS_V4, TLS, SSL. If none of the
- selected methods are supported by the server, an insecure login
- is used as a fallback. Note, by the way, that SSL or TLS can be
- used to secure an anonymous connection.
-
- SET FTP AUTOAUTHENTICATION { ON, OFF }
- Tells whether authentication should be negotiated by the FTP
- OPEN command. Default is ON. Use SET FTP AUTOAUTHENTICATION OFF
- to force a clear-text, unencrypted connection to FTP servers
- (such as the one at the Kermit FTP site) that normally would
- try to negotiate secure authentication and encryption.
-
- SET FTP AUTOENCRYPTION { ON, OFF }
- Tells whether encryption (privacy) should be negotiated by the
- FTP OPEN command, which can happen only if secure
- authentication is also negotiated. Default is ON.
-
- SET FTP AUTOLOGIN { ON, OFF }
- Tells Kermit whether to try logging in automatically when you
- make an FTP connection, as opposed to letting you do it "by
- hand" with the FTP USER command.
-
- SET FTP COMMAND-PROTECTION-LEVEL { CLEAR, CONFIDENTIAL, PRIVATE, SAFE
- }
- Determines the level of protection applied to the command
- channel:
-
- CLEAR Data is sent in plaintext and not protected against tampering.
- CONFIDENTIAL Data is encrypted but not protected against tampering.
- PRIVATE Data is encrypted and is protected against tampering.
- SAFE Data is sent in plaintext but protected against tampering.
-
- The default is PRIVATE.
-
- SET FTP CREDENTIAL-FORWARDING { ON, OFF }
- Tells whether end-user credentials are to be forwarded to the
- server if supported by the authentication method (GSSAPI-KRB5
- only). This is often required to allow access to distributed
- file systems (e.g. AFS.)
-
- SET FTP DATA-PROTECTION-LEVEL { CLEAR, CONFIDENTIAL, PRIVATE, SAFE }
- Tells what level of protection is applied to subsequent data
- channels. The meanings of the protection-level keywords are the
- same as for SET FTP COMMAND-PROTECTION-LEVEL. The default is
- PRIVATE.
-
- SET FTP SRP CIPHER name
- Specifies the cipher to be used for encryption when SRP
- authentication is in use. The list of possible choices is
- computed based on the capabilities of the local SRP library and
- includes NONE plus zero or more of the following:
-
- BLOWFISH_ECB CAST5_ECB DES_ECB DES3_ECB
- BLOWFISH_CBC CAST5_CBC DES_CBC DES3_CBC
- BLOWFISH_CFB64 CAST5_CFB64 DES_CFB64 DES3_CFB64
- BLOWFISH_OFB64 CAST5_OFB64 DES_OFB64 DES3_OFB64
-
- The default is DES3_ECB.
-
- SET FTP SRP HASH name
- Specifies the hash to be used for data protection when SRP
- authentication is in use. The choices are MD5 and SHA. The
- default is SHA.
-
- Command-line options:
-
- -k name
- Specifies the realm to be used with Kerberos 4 authentication
- (= SET AUTH K4 REALM name).
-
- -f
- Enables forwarding of Kerberos 5 credentials to the host when
- using GSSAPI authentication (= SET AUTH K5 FORWARDABLE ON).
-
- -x
- Enables autoencryption (= SET FTP AUTOENCRYPTION ON).
-
- -c cipher
- Specifies the kind of cipher to be used for encryption with SRP
- authentication. Equivalent to SET FTP SRP CIPHER, with the same
- choices. If this option is not given, CAST5_CBC is used.
-
- -H hash
- Specifies the hash to be used for encryption with SRP
- authentication. Equivalent to SET FTP SRP HASH, with the same
- choices. If this option is not given, SHA is used.
-
- -z debug
- Turns on SSL/TLS debugging.
-
- -z secure
- Requires secure connection.
-
- -z certsok
- Says to accept all certificates without checking validity.
-
- -z verify=n
- Sets certificate verification mode to the given number, n:
- 0 = no verification
- 1 = verify certificate if presented
- 2 = require verification of certificate
-
- -z cert=filename
- Specifies a file containing a client certificate to be
- presented to the FTP server.
-
- -z key=filename
- Specifies a file containing a private key matching the client
- certificate.
-
- -z !krb4
- (nokrb4) Disables the use of Kerberos 4.
-
- -z !gss
- -z nogss
- Disables the use of GSSAPI - Kerberos 5.
-
- -z !srp
- -z nosrp
- Disables use of SRP.
-
- -z !ssl
- -z nossl
- Disables the use of SSL.
-
- -z !tls
- -z notls
- Disables the use of TLS.
-
- Caution: If your FTP connection is secured via AUTH TLS, it is not
- possible to interrupt a file transfer. This is a limitation of all
- known FTP servers that support AUTH TLS.
-
- Note that when using certain security methods, such as SSL or TLS, you
- may be prompted to confirm or verify certain actions or conditions,
- for example, whether to accept self-signed certificates. This can
- interfere with unattended operation of scripts; see [234]Section 3.10.

-
- 3.3. Setting FTP Preferences FTP preferences can be set globally and
- persistently with the commands in the following sections; many of
- these can also be overridden on a per-command basis with switches that
- have the same name.
-
- 3.3.1. Logs, Messages, and Other Feedback
-
- You can control the amount of feedback received from your FTP session
- with the commands in this section. First, you can create a log of your
- FTP transfers with the following commands:
-
- SET TRANSACTION-LOG { VERBOSE, FTP, BRIEF }
- Selects the log format. VERBOSE is the default, and is
- described in [239]the manual. FTP chooses a WU-FTPD format, the
- same as is used by the popular FTP server. BRIEF creates
- per-file records in comma-separated-list format. For greater
- detail, see [240]Section 4.17 of the [241]C-Kermit 7.0 Update
- Notes.
-
- LOG TRANSACTIONS filename
- Records FTP (or Kermit, or any other protocol) uploads and
- downloads in the given file using the format selected by the
- most recent SET TRANSACTION-LOG command, if any, or else the
- default format.
-
- FTP screen messages and displays are controlled by the following
- commands:
-
- SET TRANSFER DISPLAY { FULLSCREEN, CRT, SERIAL, BRIEF, NONE, OFF }
- FTP transfers use Kermit's normal file-transfer display styles.
- Use this command to choose the desired format; the default on
- most platforms is FULLSCREEN. The display is automatically
- disabled if Kermit is running in the background or in batch.
- BRIEF is always used for command-line initiated transfers
- (unless suppressed by -q). While a file-transfer is in
- progress, you can interrupt it in the normal Kermit way by
- typing one of the following keys or key combinations:
- X - Cancel current file but go on to the next one (if any).
- Z - Cancel the entire transfer. Ctrl-L or Ctrl-W - Refresh
- the file-transfer display (if any).
-
- SET FTP DISPLAY { FULLSCREEN, CRT, SERIAL, BRIEF, NONE, OFF }
- Like SET TRANSFER DISPLAY, but applies only to FTP connections,
- and does not affect Kermit- or other protocol file transfers.
-
- SET QUIET { ON, OFF }
- This command applies to Kermit in general, not just FTP. OFF by
- default; when ON, it surpresses most messages from most
- commands as well as the file-transfer display.
-
- SET FTP PROGRESS-MESSAGES { ON, OFF }
- Tells whether Kermit should print locally-generated feedback
- messages for each non-file-transfer command. ON by default.
-
- SET FTP VERBOSE-MODE { ON, OFF }
- Tells whether to display all responses from the FTP server. OFF
- by default. This shows all responses to all commands, except
- when the file-transfer display is active, and unless you have
- SET QUIET ON. When OFF, responses are shown only for commands
- such as FTP PWD whose purpose is to display a response.
-
- SET FTP DEBUG { ON, OFF }
- Tells whether local client debugging information should be
- displayed. OFF by default. When ON, the commands that are sent
- to the server are shown, as well as its responses (even if
- VERBOSE-MODE is OFF), plus additional informational messages
- are printed regarding the progress of secure operations. Also,
- the temporary file created by the [242]MGET command is not
- deleted so you can see what's in it.
-
- Set all of these to OFF when silent running is desired.
-
- 3.3.2. Operational Preferences
-
- FTP DISABLE new-protocol-feature-name
- FTP ENABLE new-protocol-feature-name
- Explained in [243]Section 3.11.
-
- SET FTP AUTOLOGIN { ON, OFF }
- If you give this command prior to opening an FTP connection, it
- controls whether Kermit tries to log you in automatically as
- part of the connection process. Normally ON, which means the
- username and password are sent automatically (and prompted for
- if they are not yet known). When OFF, FTP OPEN connects to the
- server without logging in. OFF is equivalent to the -n
- command-line option when using Kermit's FTP command-line
- personality. See [244]Section 3.1.4 for usage.
-
- SET FTP PASSIVE-MODE { ON, OFF }
- ON by default, to avoid random TCP port assignment for data
- connections, which can prevent FTP protocol from working
- through firewalls and network address translators (for more on
- these topics, see the [245]Kermit security reference. Set to
- OFF in case the FTP server does not support passive mode, or in
- case the client has problems with it (it has been observed, for
- example, that when using passive mode, the SCO XENIX 2.3.4
- TCP/IP stack hangs in the connect() call forever). Synonyms:
- PASSIVE [ ON ], PASSIVE OFF, PASV [ ON ], PASV OFF.
-
- SET FTP SEND-PORT-COMMANDS { ON, OFF }
- This command determines whether the FTP client sends a new PORT
- command to the server when accepting incoming data connections
- (as when not using passive mode.) When PASSIVE-MODE is OFF and
- SET SEND-PORT is OFF, the port that was originally specified is
- reused. This is the default behavior for normal FTP clients but
- it is not compatible with many firewalls.
-
- SET FTP CHARACTER-SET-TRANSLATION { ON, OFF }
- Whether to translate character sets when transferring files
- with FTP (explained in [246]Section 3.7). OFF by default.
-
- SET FTP SERVER-CHARACTER-SET name
- Tells Kermit the character set used by the FTP server, UTF-8 by
- default ([247]Section 3.7).
-
- SET FTP SERVER-TIME-OFFSET delta-time
- Tells Kermit to apply the given [248]delta time to file
- timestamps provided by the server for its files; for use when
- (for example) the server does not have its timezone set
- correctly.
-
- SET FTP ERROR-ACTION { PROCEED, QUIT }
- When transferring a group of files with FTP, and an error
- occurs with one of the files, Kermit normally goes on the next
- file. Use SET FTP ERROR-ACTION to QUIT to make Kermit stop the
- transfer immediately and fail if an error occurs with any
- single file in the group. Example: you have given Kermit a list
- of files to send, and one of the files can not be found, or
- read permission is denied. Note that cancelling a file by
- typing 'X' during transfer is not considered an error (if you
- want to cancel the entire transfer, type 'Z' or Ctrl-C).
-
- SET FTP PERMISSIONS { AUTO, ON, OFF }
- When uploading files with PUT or MPUT, this tells whether
- Kermit should send each file's permissions. The default is OFF,
- which means not to send permissions, in which case the uploaded
- file's permissions are set by the FTP server according to its
- own criteria. ON means to send them, AUTO means to send them
- only if the client (Kermit) and server are on like platforms
- (e.g. both UNIX). This command has no effect when downloading,
- since the FTP protocol does not include a way for the server to
- inform the client of a file's permissions. Also see [249]FTP
- PUT /PERMISSIONS. Note that setting permissions after uploading
- is likely to work (correctly or at all) only when the client
- and server platforms are alike (e.g. both of them are some form
- of UNIX). Also note that Windows files don't have permissions.
- Also see [250]FTP CHMOD.
-
- SET FTP DATES { ON, OFF }
- When downloading files with GET or MGET, this tells whether
- Kermit should try to set the received file's date from the
- server's date. FTP DATES is ON by default. Note, however, that
- FTP protocol does not allow date preservation when uploading.
- So at best, SET FTP DATES ON can work only when downloading,
- and then only when the server agrees to furnish file dates.
-
- SET FTP FILENAMES { AUTO, CONVERTED, LITERAL }
- When uploading (sending) files, this tells whether to convert
- outbound filenames to "common form". This means allowing only
- one period in a name, uppercasing any lowercase letters,
- replacing spaces by underscores, etc. AUTOMATIC is the default,
- meaning LITERAL when client and server are the same type of
- system (e.g. UNIX) and CONVERTED otherwise. Special case: if
- the setting is AUTOMATIC and the client is not UNIX and the
- server identifies itself as UNIX, Kermit uses a less-strict
- form of conversion, in which lowercase letters are not
- uppercased and the filename can contain any number of periods,
- but spaces are still converted to underscore. When receiving,
- conversion generally means to change all-uppercase names to
- lowercase and spaces to underscore.
-
- SET FTP UNIQUE-SERVER-NAMES { ON, OFF }
- Applies only to uploads. Tells the server to create new, unique
- names for incoming files that have the same names as existing
- files. OFF by default, in which case the server overwrites
- existing files with new files of the same name. When ON, the
- server uses its own built-in method for creating new names for
- incoming files; for example, appending a period (.) and a
- number to the name. CAUTION: Use this option only if you do not
- need to refer to the file after it is uploaded, since FTP
- protocol provides no mechanism for the client to find out what
- name was assigned by the server.
-
- SET FTP COLLISION { ... }
- When downloading, what to do if an incoming file has the same
- name as an existing file. Options are the same as for SET FILE
- COLLISION. If this command is not given, Kermit's regular FILE
- COLLISION setting is used. If this command is given, it
- overrides the FILE COLLISION setting for FTP transfers only.
- See [251]Section 3.6.2 for details.
-
- SET FTP TYPE { TEXT, BINARY, TENEX }
- Changes the default transfer mode. When sending (uploading)
- files, this command has no effect unless you disable automatic
- text/binary mode switching ([252]Section 4) with SET FILE SCAN
- OFF or SET TRANSFER MODE MANUAL. When receiving (downloading)
- files, this command establishes the transfer mode to be used
- when a filename does not match any of Kermit's text or binary
- filename patterns, unless you use SET FTP
- GET-FILETYPE-SWITCHING or SET TRANSFER MODE MANUAL to disable
- automatic switching, in which case, this command establishes
- the transfer mode for all downloaded files. In all cases,
- however, the FTP TYPE can be overridden in any GET or PUT
- command by including a /TEXT (/ASCII), /BINARY, or /TENEX
- switch. The FTP TYPE is independent of the Kermit FILE TYPE
- setting. TENEX is used for sending 8-bit binary files to 36-bit
- platforms such as TOPS-10, TOPS-20, and TENEX, and getting them
- back again. Synonym: ASCII = TEXT. Note: there is also an FTP
- TYPE command, which does what SET FTP TYPE does but also sends
- a TYPE command to the server immediately if the given type is
- different from the current one.
-
- If you want want specific FTP preference settings to be in effect for
- all your Kermit FTP sessions, put the desired SET FTP commands in your
- Kermit customization file (~/.mykermrc in UNIX, K95CUSTOM.INI in
- Windows).

- _________________________________________________________________
-
- 3.4. Managing Directories and Files
-
- In Kermit, commands for directory and file management can refer to:
-
- * The local computer
- * A remote computer when you have a connection to a Kermit server or
- IKSD.
- * A remote computer when you have a connection to an FTP server.
-
- (There can also be an HTTP connection, but the commands in this
- section don't apply to HTTP connections.)
-
- Thus in general, each such command comes in three forms:
-
- 1. With no prefix in C-Kermit 8.0.200, it refers to the local
- computer (CD, DIR, etc). In C-Kermit 8.0.201 and later, however,
- the "locus" switches to automatically to the remote FTP server
- when you make an FTP connection (see the SET LOCUS description
- [257]Section 7); thus C-Kermit 8.0.201 acts almost exactly like a
- regular FTP client when it has an FTP connection, yet still acts
- like itself on other kinds of connections.
- 2. With the REMOTE prefix, it is for a Kermit server (REMOTE CD,
- REMOTE DIR).
- 3. With the FTP prefix, it's for an FTP server (FTP CD, FTP DIR).
- 4. Also see [258]Section 3.8, which explains "R-commands" and
- "L-commands".
-
- Kermit's FTP file and directory management commands are as follows.
- When an R-command is included in the Synonyms list, be sure to read
- [259]Section 3.8 about rules for use of R-commands.
-
- FTP CD [ directory ]
- Tells the FTP server to change its default (working) directory
- to the one given, which usually must be expressed in the syntax
- of the server platform (UNIX, VMS, etc). If the directory is
- not specified, the result depends on the FTP server -- it might
- complain that the command is illegal, or it might change to
- your original login directory. Synonyms: FTP CWD (Change
- Wording Directory); RCD.
-
- FTP CDUP
- Tells the FTP server to change its default (working) directory
- to the parent directory of its current one (equivalent to
- "cd .." in UNIX, or "cd [-]" in VMS). Synonyms: RCDUP, FTP UP.
-
- FTP PWD
- Asks the FTP server to report ("print") its current working
- directory. Synonym: RPWD.
-
- FTP MKDIR directory
- Asks the FTP server to create the directory whose name is
- given. In general, the name must be in the syntax of the
- server's file system, and it must be either absolute (a full
- pathname) or relative to the server's current (working)
- directory. This command fails if the directory can't be created
- for any reason, including that it exists already. Synonym:
- RMKDIR.
-
- FTP RMDIR directory
- Asks the FTP server to remove the directory whose name is
- given. The rules are the same as for MKDIR, plus in most cases,
- the server will not remove any directory unless it is empty.
- Synonym: RRMDIR.
-
- FTP DIRECTORY [ filespec ] [ redirectors ]
- Tells the FTP server to send a directory listing of the
- specified files. If no filespec is given, the server lists all
- files in its current working directory. The results are in
- whatever format the server chooses to send them. You can use
- UNIX-like redirectors to send the listing to a file or a
- pipeline, exactly as with the regular Kermit client/server
- REMOTE DIRECTORY command ([260]Using C-Kermit, Chapter 11).
- Synonym: RDIRECTORY. Examples:
-
- ftp dir ; Show listing of all files on screen
- ftp dir *.txt ; List *.txt files on screen
- ftp dir *.txt > somefile ; Put listing in somefile
- ftp dir *.txt >> somefile ; Append listing to somefile
- ftp dir *.txt | sort > somefile ; Put sorted listing in somefile
- ftp dir | more ; Runs list through "more"
- ftp dir | sort | more ; Runs list through "sort" and "more"
-
- FTP VDIRECTORY [ filespec ] [ redirectors ]
- "Verbose" directory. This is an alternative FTP DIRECTORY
- command primarily for use with DECSYSTEM-20 (TOPS-20) FTP
- servers, which send only filenames when given a DIRECTORY
- command; the VDIRECTORY command makes them also send file
- sizes, dates, and attributes.
-
- FTP CHECK filespec
- Asks the FTP server whether the given file exists or, if the
- filespec contains wildcards, if any files match, and this
- command succeeds or fails accordingly.
-
- FTP MODTIME filename
- Asks the FTP server, via the not-yet-standard FTP MDTM command,
- to send the modification date and time of the given file. The
- response should be a numeric string in the format:
- yyyymmddhhmmssxxxxx... where yyyy is the year, mm is the month,
- dd is the day, hh is the hour (0-23), mm is the minute, ss is
- the second, and xxx... is the optional fraction of the second
- (0 or more digits). The date and time is expressed in UTC (GMT,
- Zulu, Zero-Meridian). The result is available programmatically
- in the [261]\v(ftp_message) variable, and is understandable by
- Kermit's date-time switches and functions. For example, suppose
- we want to upload all local files that are newer than a
- particular file on the server:
-
- C-Kermit> ftp modtime signpost
- C-Kermit> echo \v(ftp_message)
- 20010807113542.014
- C-Kermit> ftp mput /after:\v(ftp_message)GMT *
-
- Note that we must append "GMT" to the date-time string to let
- the /AFTER switch know the time is GMT rather than local.
-
- FTP SIZE filename
- Asks the FTP server to send the size (in bytes) of the given
- file. The result might vary depending on whether the current
- FTP TYPE is binary or text ("ascii"). For a reliable byte
- count, do FTP TYPE BINARY first. The result is available
- programmatically in the [262]\v(ftp_message) variable.
-
- FTP CHMOD permissions filename
- Tells the FTP server to set the permissions (protection) of the
- given file to the ones given. The permissions and filename must
- be given in whatever syntax is required by the server. Example
- (for a UNIX-based FTP server):
-
- ftp chmod 664 oofa.txt
-
- Not all servers support this command. For non-UNIX-based
- servers, you might need to use FTP QUOTE or FTP SITE and the
- appropriate platform-specific FTP server command.
-
- FTP UMASK [ number ]
- This command is probably specific to UNIX-based servers; it
- sets the UNIX "umask", which is the default permissions mask
- for new (in this case, incoming) files. Crudely put, the UNIX
- umask is an octal representation of a binary number in in which
- a 1 bit stands for a permission bit that must be 0, and a 0 bit
- stands for a permission bit that can be 0 or 1 depending on
- other factors, such as the permissions of the parent directory.
- Example: "umask 007" requires that new files are created
- without read/write/execute world permission. If the number is
- not specified, the server's current umask is reported.
-
- FTP RENAME filename newname
- Asks the FTP server to rename the file whose name is "filename"
- to "newname". Works only for one file; can not be used with
- wildcards. The server's interpretation of "newname" can vary
- (in some cases it must be a filename, in others perhaps it can
- also be a directory name, in which case if the filename denote
- a regular file, the file might be moved to the given
- directory). Some servers might allow files to be renamed
- ("moved") between physical disks or partitions, others might
- not. Synonym: RRENAME.
-
- FTP DELETE [ switches ] filespec [ filespec [ ... ] ]
- Tells the FTP server to delete the file or files listed. Each
- file specification may, but need not, contain wildcard
- characters to match multiple files. File specifications and
- wildcard syntax must be those of the server. Any file
- specifications that contain spaces must be enclosed in braces
- or doublequotes. FTP DELETE switches are:
-
- /ERROR-ACTION: /FILENAMES: /NOBACKUPFILES /QUIET
- /EXCEPT: /LARGER-THAN: /NODOTFILES /NOPAGE
- /PAGE /RECURSIVE /SMALLER-THAN:
-
- When used with FTP DELETE, the /RECURSIVE switch deletes files
- but not directories, and furthermore depends on the server
- providing recursive file lists, which is not the normal
- behavior. For further details, see the decriptions of these
- switches in [263]Section 3.6. Synonyms: FTP MDELETE (Kermit
- makes no distinction between DELETE and MDELETE); RDELETE.
-
- FTP TYPE { TEXT, BINARY, TENEX }
- Tells the FTP server to change its file-transfer type to the
- one given, immediately. See [264]SET FTP TYPE for details.

-
- 3.5. Uploading Files With FTP
-
- Uploading means sending files from the client (Kermit) to the FTP
- server. The basic command for uploading files with FTP is PUT:
-
- FTP PUT [ switches ] [ filespec [ as-name ] ]
- Uploads (sends) the file or files that match the file
- specification, which may include wildcards, to the server. If
- no filespec is given, the names of files to send are taken from
- the /LISTFILE: file, if any, otherwise from the SEND-LIST, if
- any. Unless you go out of your way to prevent it, Kermit
- determines the transfer mode (text or binary) for each file
- automatically, and switches automatically on a per-file basis.
- If an as-name is given, the file is sent under that name
- instead of its own (if an as-name is given with a wildcard
- filespec, the result is a bit more complicated, and is
- explained later in this section).
-
- Unlike normal FTP clients, Kermit does not prompt you by default (or
- at all) for each file; it just sends them, just as it does with Kermit
- protocol. The filespec can be a literal filename or a Kermit pattern,
- described in:
-
- [269]http://www.columbia.edu/kermit/ckermit70.html#x4.9
-
- Kermit patterns are equivalent to C-Shell patterns and provide a fair
- amount of flexibility in selecting which files to send, which is
- augmented by the file-selection switches presented in [270]Section
- 3.5.1.
-
- FTP MPUT [ switches ] filespec [ filespec [ ... ] ]
- FTP MPUT is just like FTP PUT except it allows you to give more
- than one file specification, and it does not allow an as-name
- in the file list. However, as-names can be given to either PUT
- or MPUT with the /AS-NAME: switch.
-
- If a PUT or MPUT command results in one file being uploaded, it
- succeeds if the file is uploaded completely and fails otherwise. If
- more than one file is selected for upload, success or failure depends
- on the [271]FTP ERROR-ACTION setting; if it is PROCEED (the default
- setting), then the [M]PUT command succeeds if at least one of the
- files was completely uploaded, and fails otherwise, If FTP
- ERROR-ACTION is QUIT, the [M]PUT command succeeds if all selected
- files were uploaded successfully, and fails if any file failed.
-
- FTP uploads may be interrupted just like Kermit uploads. While the
- transfer is in progress, type:
-
- X to interrupt the current file and go on to the next file.
- Z to cancel the current file and all remaining files.
- ^C (Control-C): Like Z, but might act more quickly.
-
- MPUT may be used as in regular FTP clients, but it is not required to
- send multiple files; in Kermit it is required only if you want to give
- multiple file specifications. Examples:
-
- ftp put oofa.txt ; Send a single file oofa.txt
- ftp put oofa.txt budget.txt ; Send single file oofa.txt as budget.txt
- ftp put *.txt ; Send all *.txt files
- ftp mput *.txt ; Send all *.txt files (same as "put *.txt")
- ftp mput *.txt foo.bar ; Send all *.txt files plus foo.bar
-
- The distinction between PUT and MPUT is important only when more than
- one filespec is given, just like the distinction between Kermit SEND
- and MSEND:
-
- ftp put oofa.txt budget.txt ; Send oofa.txt AS budget.txt
- ftp mput oofa.txt budget.txt ; Send oofa.txt AND budget.txt
-
- If the source file specification includes any path segments, for
- example:
-
- put /tmp/oofa.txt
- put subdir/another/andanother/oofa.txt
-
- the path portion is stripped from the filename that is sent to the
- server. However, if an as-name contains a path, it is retained.
- Examples:
-
- ftp put /usr/doc/oofa.txt ; Send as "oofa.txt".
- ftp put oofa.txt /tmp/oofa.txt ; Send as "/tmp/oofa.txt"
-
- The latter example sends the file oofa.txt from your current local
- directory to the server's /tmp directory. This works only if the
- server uses the same directory notation that you used in the as-name
- AND the given directory already exists on the server AND if you have
- write access to it.
-
- Use caution when uploading from a case-sensitive file system, such as
- UNIX, to a file system that is not case sensitive, such as Windows or
- VMS. If you have two files in UNIX, AA and aa and upload both of them,
- the second one will overwrite the first. The only way around this
- provided by FTP protocol is its "unique server names" feature (SET FTP
- UNIQUE-SERVER-NAMES or the /UNIQUE switch described below).
- _________________________________________________________________
-
- 3.5.1. FTP PUT Switches
-
- FTP PUT and MPUT are similar in format and behavior to the regular
- Kermit SEND and MSEND commands, and they allow most of the same
- optional switches:
-
-C-Kermit>ftp put ? Filename, or switch, one of the following:
- /after: /larger-than: /rename-to:
- /array: /listfile: /server-character-set:
- /as-name: /local-character-set: /server-rename-to:
- /before: /move-to: /simulate
- /binary /nobackupfiles /smaller-than:
- /command /nodotfiles /tenex
- /delete /nofollowlinks /text
- /dotfiles /not-after: /transparent
- /error-action: /not-before: /type:
- /except: /permissions: /update
- /filenames: /quiet /unique-server-names
- /filter: /recover
- /followlinks /recursive
-
- Since most of these switches are common to Kermit's SEND and MSEND
- commands, they described only briefly here. For greater detail see:
-
- [272]http://www.columbia.edu/kermit/ckermit70.html#x1.5 (explanation
- of switches)
- [273]http://www.columbia.edu/kermit/ckermit70.html#x4.7
- (file-transfer switches)
-
- First the file-selection switches:
-
- /AFTER:date-time
- /BEFORE:date-time
- /NOT-AFTER:date-time
- /NOT-BEFORE:date-time
- Only send those files modified on or after or before the given
- date and time. These switches can be combined to select files
- modified between two date/times. Various date-time formats are
- accepted; if the date-time contains spaces, it must be enclosed
- in braces or doublequotes. See
- [274]http://www.columbia.edu/kermit/ckermit70.html#x1.6 and
- [275]Section 8.13 of this document for details about date-time
- formats. Examples:
-
- ftp put /after:{1 jan 2000 0:00:00} *
- ftp put /after:-5days *
-
- /LARGER-THAN:number
- /SMALLER-THAN:number
- Only send files larger (smaller) than the given number of bytes
- (octets). These switches can be combined to select files in a
- certain size range.
-
- /TYPE:{TEXT,BINARY}
- Only send files that are the given type, which is determined
- for each file just before sending it by file scanning. BINARY
- includes TENEX; if you have included a /TENEX switch, or
- previously given a [SET] FTP TYPE TENEX command, binary files
- are sent in TENEX, rather than BINARY mode.
-
- /[NO]DOTFILES
- [Don't] include files whose names begin with dot (.). By
- default, such files are not included unless your filespec
- explicitly mentions them.
-
- /NOBACKUPFILES
- Don't include files whose names end with .~nnn~, where nnn is a
- number, e.g. oofa.txt.~27~. These are backup files created by
- Kermit, EMACS, and other applications. By default, backup files
- are included.
-
- /NOFOLLOWLINKS
- (UNIX only) Skip over symbolic links rather than following them
- (default). This applies to wildcard and/or recursive [M]PUTs;
- if a single filename is given, and it happens to be a symbolic
- link, the file it points to is sent.
-
- /FOLLOWLINKS
- (UNIX only) Always follow (resolve) symbolic links, even in
- wildcard or recursive [M]PUTs. Use with caution. Watch out for
- circular links, endless loops, etc.
-
- /EXCEPT:pattern
- Exception list -- don't send files whose names match the given
- pattern. See [276]Section 1.5.4 of the [277]C-Kermit 7.0 Update
- Notes for details. If you want to exclude a directory from a
- recursive [M]PUT, use /EXCEPT:{dirname/*}.
-
- /RECURSIVE
- Sends the desired files from the current (or given) directory,
- plus all directories beneath it, including empty directories,
- replicating the directory structure on the server. No special
- capabilities are required in the server, but of course your
- login ID on the server must have the appropriate access and
- permission to create directories. Recursive PUTs work not only
- between like platforms (e.g. UNIX to UNIX) but also between
- unlike ones (e.g. UNIX to VMS or Windows), in which case
- text-file format differences are handled by Kermit's automatic
- text/binary mode switching ([278]Section 4) and character-set
- translation ([279]Section 3.7). Synonym: /SUBDIRECTORIES.
-
- /UPDATE
- Send only files that have changed since last time ([280]Section
- 3.5.2).
-
- /ARRAY:arrayname
- The "file" to be sent is an array, or a segment of one, rather
- than a real file. In this case the other selection switches
- don't apply. The array contents are sent in text mode, and each
- array element is treated as a line. Example:
-
- ftp put /as-name:array.txt /array:&a
-
- (or, to send a segment of the array, /array:&a[100:199]). If
- you don't include an /AS-NAME, a name of "_array_x_" is used
- (where x is the array letter). If you include this switch, most
- other switches are meaningless and ignored.
-
- /COMMAND
- The "file" to be sent is the standard output of a command,
- rather than a real file. It is sent in text or binary mode
- according to the prevailing FTP TYPE, which can be overridden
- with a /TEXT or /BINARY switch. Example: Example:
-
- ftp put /command /as-name:{userlist} {finger | sort -r}
-
- /LISTFILE:filename
- Tells Kermit to obtain the list of files to be sent from the
- file whose name is given. This file must contain one file
- specification (which may be wild) per line. If the list
- includes files from different directories, such as a recursive
- listing of a directory tree, the paths are recreated on the
- server (if possible) if you include the /RECURSIVE switch;
- otherwise all the files are sent to the current directory on
- the server.
-
- Now the other switches:
-
- /AS-NAME:text
- If a single file is being sent, send it with the given text as
- its name. If multiple files are being sent, the text must be a
- template that includes variables such as \v(filename),
- \v(filenumber), \v(ntime), to allow dynamic creation of each
- name. The same applies to the as-name field of the FTP PUT
- command. If this switch is not included (and an as-name is not
- included as the second filename to PUT), each file is sent with
- its own name.
-
- /BINARY
- /TEXT
- /TENEX
- Forces this upload to take place in the given mode, regardless
- of the current FTP TYPE setting, and without automatic
- text/binary switching. /ASCII is a synonym for /TEXT.
-
- /FILTER:command
- Specifies that the file(s) is/are to be passed through the
- given command or pipeline on their way to the server. Example:
-
- ftp put /binary /filter:{gzip -c \v(filename)} /as-name:\v(filename).gz *
-
- /TRANSPARENT
- /LOCAL-CHARACTER-SET:name
- /SERVER-CHARACTER-SET:name
- Character-set translation for text files, explained in
- [281]Section 3.7.
-
- /ERROR-ACTION:{PROCEED,QUIT}
- Overrides the prevailing [282]FTP ERROR-ACTION for the duration
- of this PUT or MPUT command only.
-
- /RECOVER
- Resume an interrupted transfer where from the point of
- interruption (explained in [283]Section 3.5.2). Synonym:
- /RESTART.
-
- /DELETE
- Tells Kermit to delete each source file immediately after, and
- only if, it has been uploaded completely and successfully.
- This, in effect, moves the file from the client to the server.
-
- /MOVE-TO:directory
- Tells Kermit to move each source file to the named local
- directory after, and only if, it has been uploaded completely
- and successfully.
-
- /RENAME-TO:template
- Tells Kermit to rename each (local) source file according to
- the given template after, and only if, it has been uploaded
- completely and successfully. The template works as in /AS-NAME.
-
- /SERVER-RENAME-TO:template
- Tells Kermit to ask the server to rename each file according to
- the given template as soon as, and only if, it has been
- received completely and successfully. The template works as in
- /AS-NAME. Requires write and rename access on the server, so
- doesn't usually work with (e.g.) anonymous uploads to public
- incoming areas where the permissions don't allow renaming.
- Examples:
-
- ftp mput /server-rename:\v(filename).ok *
- Appends ".ok" to each filename on the server when it's
- finished uploading.
-
- ftp mput /as-name:\v(filename).tmp /server-rename:\v(filename) *
- This is the reverse of the previous example; it uses a
- temporary name while uploading is in progress and reverts
- the file to its real name when uploading is complete.
-
- ftp mput /as-name:\v(filename)
- /server-rename:../final/\v(filename) *
- Moves the file from the working directory to a final
- directory when the upload is complete, but in this case
- you have to know the pathname syntax of the server. If
- the rename fails, the [M]PUT command fails according to
- the [284]FTP ERROR-ACTION selection.
-
- /FILENAMES:{AUTOMATIC,CONVERTED,LITERAL}
- Overrides the [285]FTP FILENAMES setting for this upload only.
-
- /PERMISSIONS:{ON,OFF}
- Overrides the [286]FTP PERMISSIONS setting for this upload
- only.
-
- /UNIQUE
- Tells Kermit to tell the server to give [287]unique names to
- incoming files that would otherwise overwrite existing files
- that have the same name. This switch conflicts with /UPDATE,
- /RECOVER, /PERMISSIONS, and /SERVER-RENAME since the client has
- no way of knowing the name assigned by the server.
-
- /QUIET
- Don't display file-transfer progress or statistics.
-
- /SIMULATE
- Shows which files would be sent without actually sending them.
- Useful (for example) with /UPDATE (next section). The results
- are shown in the file-transfer display (if it is not disabled)
- and in the transaction log (if one is active). Hint: use SET
- TRANSFER DISPLAY BRIEF.
- _________________________________________________________________
-
- 3.5.2. Update Mode
-
- When you include the /UPDATE switch, this means to skip sending any
- file that already exists on the server if the local file's
- modification date/time is not later than that of the corresponding
- file on the server. Here is a typical application for update mode:
- Suppose that on Computer A, you maintain a large set of files (say, a
- collection of Web pages and graphics images, or the source files for a
- software application), and you need to keep a parallel copy on another
- Computer, B. Of course you could upload the entire collection every
- day:
-
- cd source-directory
- ftp computerb.xyzcorp.com
- ( authentication details... )
- ftp cd target-directory
- ftp put [ switches ] *
-
- But if the total size is large or the network slow, this would be
- unnecessarily time-consuming. Worse, if other users or sites had to
- update whenever new files appeared in B's directory, this would cause
- them unnecessary work. By including the /UPDATE switch:
-
- ftp put /update [ other-switches ] *
-
- only those files that changed since last time are uploaded. Here's how
- it works. For each local file that is selected for uploading:
-
- * The remote filename is determined in the normal way, according to
- the [288]FTP FILENAMES setting, /FILENAMES switch, or the as-name,
- if any.
- * Kermit sends an MDTM (modification time) command for the
- corresponding remote filename to the server.
- * If the server does not understand the MDTM command, the file is
- sent.
- * If the server can't find a file with the given name, the file is
- sent.
- * If the local file's modification time is later than that of the
- remote file, the file is sent.
- * Otherwise -- the remote file exists but its modification time is
- equal to or earlier than that of the local file -- the file is
- skipped.
-
- All time comparisons take place in Coordinated Universal Time
- (UTC)([289]1), also known as GMT or Zulu time: Timezone 0; standard
- time, without daylight savings.
-
- WARNING: Some FTP servers, such as Novell NWFTPD.NLM, ignore or
- misimplement the FTP specification and send local time rather than
- UTC.
-
- Update mode is useful only when always used in the same direction.
- When you upload (PUT) a file with FTP, the destination file receives
- the current timestamp on the server's computer, not the original
- file's timestamp ([290]2). If you try to FTP PUT /UPDATE the same file
- again, it will be skipped (as expected) since the remote copy is
- newer. However, if you try to FTP GET /UPDATE the same file
- ([291]Section 3.6), it will be transferred for the same reason.
-
- To check the availability of PUT /UPDATE on a particular connection,
- issue an FTP MODTIME command for a file that is known to exist on the
- server. If it succeeds, PUT /UPDATE should work and in that case, you
- can run a procedure like the one above every day: the first time, it
- sends all the files; after that, it sends only the ones that changed.
- If a transaction log is active, a notation is included for any files
- that are skipped.
-
- Notes:
- 1. Why is Coordinated Universal Time abbreviated UTC? From the
- [292]National Institute of Standards and Technology FAQ: "In 1970
- the Coordinated Universal Time system was devised by an
- international advisory group of technical experts within the
- International Telecommunication Union (ITU). The ITU felt it was
- best to designate a single abbreviation for use in all languages
- in order to minimize confusion. Since unanimous agreement could
- not be achieved on using either the English word order, CUT, or
- the French word order, TUC, the acronym UTC was chosen as a
- compromise."
- 2. The Kermit FTP client is unusual in that, when downloading only,
- it can set the received file's date from the file's date on the
- server, but this should not affect the update feature. When
- uploading to an FTP server, however, there is no mechanism for the
- client to set the date of the uploaded file on the server.
- _________________________________________________________________
-
- 3.5.3 Recovery
-
- Suppose that while you are uploading a large file over a slow
- connection, the connection is lost before the entire file is
- transferred. With most FTP clients, you would have to start over, thus
- resending the portion of the file that was sent already, and that is
- already on the server. But Kermit's /RECOVER switch (Synonym:
- /RESTART) lets you continue an interrupted transfer from the point of
- failure, thus transferring only the part that wasn't sent already. The
- prerequisites for recovery are:
-
- * The transfer must be in BINARY mode, or else the client and server
- must reside on like systems (e.g. both on some form of UNIX).
- * The FTP server must support the SIZE command.
-
- Here's how it works. When you include the /RECOVER switch:
-
- * Kermit checks for conflicting switches, such as /UPDATE and
- /UNIQUE; if /RECOVER is given with these switches an error occurs.
- If /RECOVER is given in other circumstances where it could serve
- no useful purpose (e.g. with arrays, pipes, or filters), it is
- ignored.
-
- If the switch is accepted, then for each selected file:
-
- * If it is not binary (determined by scanning) and the client and
- server are not on like platforms, recovery is canceled (the entire
- file is sent). Otherwise:
- * A SIZE command is sent for the file (using its remote name). If
- the reply indicates the file was not found, or the SIZE command
- was not understood, or any other kind of error, recovery is
- canceled. Otherwise:
- * A MDTM (modification time) command is sent for the file. If a
- valid reply is received, and the modification time of the local
- file is later than that of the remote file, recovery is canceled.
- Otherwise:
- * If the sizes of the two files are identical, the file is not sent.
- Otherwise:
- * Kermit seeks to the recovery spot in the local file, tells the
- server to APPEND the data which is about to arrive to the remote
- file, and then sends the data starting at the recovery point.
-
- To safeguard file integrity, recovery is not attempted unless all the
- preconditions are met. For the widest possible usefulness, APPEND is
- used rather than RESTART. For stream transfers (the only kind that
- Kermit supports) the results are the same.
-
- By design, the /RECOVER switch can be included with any FTP PUT or
- MPUT command, even if it specifies a group of files. This allows you
- to resume an interrupted batch transfer from where it left off. The
- files that were already completely sent are skipped, the file that was
- interrupted is recovered, and the remaining files are uploaded.
-
- By the way, it doesn't matter how the original partial file was
- uploaded -- FTP, Kermit, Zmodem, etc: as long as the preconditions are
- met, it can be recovered with FTP PUT /RECOVER, or for that matter
- also using Kermit protocol and SEND /RECOVER.
-
- A word of caution, however, when the original upload was in text mode
- with character-set translation ([293]Section 3.7):
-
- * If the original upload involved a translation from one single-byte
- character set to another (e.g. Code Page 850 to Latin-1), recovery
- is safe if you specify the same translations for the recovery. If
- you don't, the resulting file will contain a mixture of character
- sets.
- * If the original upload involved a translation that changed the
- size of the file (e.g. from an alphabetic Code Page or Latin
- Alphabet to Unicode, or vice versa), recovery is NOT safe, even if
- you specify the same translations.
-
- Kermit has no way of knowing anything about the previous upload. As a
- safeguard, an error occurs if you include /RECOVER and also specify a
- character-set of UCS2 or UTF8, since recovery can't possibly work in
- that situation. Otherwise, it's up to you to avoid unsafe recovery
- operations.

-
- 3.6. Downloading Files With FTP
-
- Although uploading files with Kermit's FTP client is just as easy and
- flexible as sending files with Kermit protocol, the same is not always
- true for downloading because FTP servers lack some of the capabilities
- of a Kermit server:
-
- * If you want to get more than one file, you have to use MGET, not
- GET, since the underlying FTP protocol is different in the two
- cases. Kermit can't "autodetect" which one you mean, as it can
- with PUT and MPUT, since it can't be expected to know the wildcard
- syntax of the remote platform and/or FTP server (the same is true
- for all other FTP clients). To complicate matters, FTP protocol
- now includes two underlying mechanisms (NLST and MLSD) for
- accomplishing MGET operations and, as explained in [298]Section
- 3.11, the two behave differently.
- * Automatic text-binary mode switching is not done by the server. It
- can be done by the client (Kermit), but in this case it is not
- based on a file scan (since there is no way for Kermit prescan a
- server file), but rather on the filename, using C-Kermit 7.0
- [299]filename patterns.
- * Some options that are available with FTP PUT can not be used with
- FTP [M]GET or don't work the same way:
- /PERMISSIONS (FTP protocol has no mechanism for this).
- /[NOT-]BEFORE, /[NOT-]AFTER (because of the timezone problem).
- /RECOVER works only in binary mode. /RECURSIVE has limited
- utility.
-
- The commands for downloading are:
-
- SET FILE DOWNLOAD-DIRECTORY [ directory ]
- As with Kermit transfers, this command, if given, tells
- C-Kermit where to store incoming files in the absence of a
- specific as-name. If not given, incoming files are stored as
- indicated by the as-name, if any, otherwise in the current
- directory, just as with Kermit transfers. The more verbose
- transfer display formats give the full pathname of each
- received file, and, in case you have trouble finding a
- downloaded file afterwards, its full path is also listed in the
- transaction log (if you kept one), and you can also ask Kermit
- where it went with the [300]WHERE command.
-
- SET FTP GET-FILETYPE-SWITCHING { ON, OFF }
- ON by default, causing Kermit to switch automatically into text
- or binary mode for each file based on whether its name matches
- a text pattern or binary pattern. Set this OFF, or use a /TEXT,
- /BINARY, or /TENEX switch to defeat this feature. Use SHOW
- PATTERNS to see the current pattern list.
-
- [ FTP ] GET [ switches ] filename [ as-name ]
- Asks the server to send the given file, and if it comes, stores
- it locally under the given as-name, if any, otherwise under its
- original name (modified according to the selected filename
- conversion option), in your download directory, if you have
- specified one, otherwise in the directory indicated in the
- as-name, if any, otherwise in your current directory. If you
- accidentally use a wildcard in the filename ("get *.txt") the
- server will reply with a message like "File not found" (unless
- there is a file whose name actually is "*.txt"). If FTP
- GET-FILETYPE-SWITCHING is ON, and in the absence of any GET
- switches to override it, the file is transferred in binary mode
- if it matches any of Kermit's binary name patterns, and in text
- mode if it matches any of Kermit's text name patterns, and in
- the prevailing FTP TYPE if it matches none of these patterns.
-
- [ FTP ] MGET [ switches ] filespec [ filespec [ filespec [ ... ] ] ]
- Like GET, but for multiple files. One or more file
- specifications can be given, and any or all (or none) of them
- can contain wildcards or can be directory names. The file list
- may not include an as-name, but you can still give one with the
- /AS-NAME: switch.
-
- In both the FTP GET and MGET commands, any filenames that contain
- spaces must be enclosed in braces or doublequotes (see [301]Section 5
- for details).
-
- FTP downloads may be interrupted just like Kermit transfers. While the
- transfer is in progress, type:
-
- * X to interrupt the current file and go on to the next file.
- * Z (or Control-C) to cancel the current file and all remaining
- files.
-
- Before proceeding, a brief word about temporary files. In FTP
- protocol, the MGET command works by requesting a file list from the
- server, and then (internally) issuing a GET command (FTP RETR protocol
- directive) for each file. The file list returned by the server can be
- any size at all, so in case it is huge, we don't store it in memory;
- instead we put it in a temporary file. For troubleshooting purposes,
- you should be aware of two points:
-
- 1. The location of the temporary file is chosen according the TMP or
- TEMP environment variables. If neither of these variables is
- defined, you might need to define it. In case there is not enough
- space on the indicated disk or partition for the server's file
- list, you might need to either clean up the temporary area, or
- redefine the environment variable to indicate a different area
- that has sufficient space.
- 2. If you want to look at the list yourself, use SET FTP DEBUG ON.
- This tells Kermit to (a) give you the full pathname of the
- temporary file at the end of each MGET command, and (b) not to
- delete it, as it normally does.

-
- 3.6.1. FTP GET Switches
-
- The following switches are available with FTP GET and MGET:
-
- /TEXT
- Specifies a text-mode transfer. Overrides the global FTP TYPE
- setting and filename pattern-matching for the duration of the
- current command only, All files are downloaded in text mode.
- Synonym: /ASCII.
-
- /BINARY
- Specifies a binary-mode transfer. Overrides the global FTP TYPE
- setting and filename pattern-matching for the duration of the
- current command only. All files are downloaded in binary mode.
-
- /TENEX
- Like /BINARY but specifies a special binary transfer mode to be
- used when getting 8-bit binary files from a 36-bit platform
- such as TOPS-10, TOPS-20, or TENEX. All files are downloaded in
- the special binary mode.
-
- /RECOVER
- This instructs Kermit to try to recover an incomplete download
- from the point of failure. Works only in binary mode, and only
- if the server supports the (not-yet-standard) FTP "REST"
- directive. See [302]Section 3.6.3 for details. Synonym:
- /RESTART.
-
- /FILENAMES:{CONVERTED,LITERAL}
- Overrides the [303]FTP FILENAMES (filename conversion) setting
- for this download only, forcing incoming filenames to be either
- converted or taken literally.
-
- /AS-NAME:text
- For GET, this is equivalent to giving an as-name after the
- filename. For MGET, this is the only way to specify alternative
- names for the incoming files. With MGET, the /AS-NAME text
- should (must) contain a Kermit variable, usually \v(filename)
- or \v(filenumber). Example:
-
- mget /text /as-name:\v(filename).new *.c
-
- This gets all ".c" files and stores them with "
-
- .new" appended to their names. See the [304]C-Kermit 7.0 Update
- Notes for details.
-
- /COMMAND
- This specifies that the incoming file is to be written to the
- standard input of a command, rather than to a file. The command
- name is the as-name from the GET command or the /AS-NAME
- argument. If you need to refer to the incoming file's name in
- the command, use \v(filename). See the description of the
- regular Kermit [305]GET /COMMAND command for details and
- examples.
-
- /QUIET
- Transfers the files quietly; don't put up a file-transfer
- display.
-
- /ERROR-ACTION:{QUIT,PROCEED}
- This switch affects only MGET. If an error occurs with a
- particular file, this tells whether to go on to the next file
- (PROCEED) or to stop right away and fail (QUIT). The default is
- PROCEED.
-
- The file selection switches are:
-
- /EXCEPT:{pattern} or /EXCEPT:{{pattern}{pattern}{...}}
- Exception list for MGET; skip downloading any file whose name
- matches any of the given patterns (when using the second
- format, up to 64 patterns may be specified). [306]CLICK HERE
- for syntax details.
-
- /SMALLER-THAN:number
- Download only files whose size is smaller than the given number
- of bytes (octets). Requires that the FTP server support the
- SIZE or MLSD directive.
-
- /LARGER-THAN:number
- Download only files whose size is greater than the given number
- of bytes. Requires that the FTP server support the SIZE or MLSD
- directive.
-
- /NOBACKUPFILES
- During MGET, don't download any files whose names end with
- backup suffixes (.~n~ where n is a number).
-
- /NODOTFILES
- During MGET, don't download any files whose names begin with
- period (.). Equivalent to /EXCEPT:{.*}.
-
- /LISTFILE:local-filename
- The given file contains a list of files to GET, one per line.
- Filenames in the listfile can contain wildcard characters in
- the syntax of the server. There is no limit on the number of
- lines in the listfile.
-
- /NAMELIST:local-filename
- If this switch is given, then instead of actually retrieving
- the selected files, the GET command retrieves a list of the
- names of the files that would be retrieved, and places it in
- the specifed file. The resulting file is an ordinary text file,
- with one filename per line, suitable for reading by a person,
- or processing by a computer program, including Kermit itself
- (FOPEN / FREAD / FWRITE / FCLOSE), and as /FILELIST: file. If
- the filename is omitted or given as "-" (dash, hyphen), the
- list goes to the screen. NOTE: if you want a copy of the
- complete list sent by the server, use SET FTP DEBUG ON, perform
- an MGET, and the temporary file containing the list will be
- kept rather than deleted (and Kermit tells you its name).
-
- /UPDATE, /COLLISION:keyword
- Explained in [307]Section 3.6.2.
-
- /RECURSIVE
- This means to try to download an entire directory tree, rather
- than just files from a particular directory. In fact, FTP
- protocol does not provide a method to request a recursive
- download (unless the server supports MLSD; see [308]Section
- 3.11), so this works only if the FTP server does it anyway,
- without being asked, as some do. In this case, Kermit detects
- that names in the returned file list contain directory
- separators, and therefore attempts to create the needed
- directories as the files arrive. But this can work only if the
- server is on the same kind of platform as the client, so the
- pathname syntax can be recognized, and also because the server
- does not switch between text and binary mode, which would be
- vital for cross-platform transfers. Use with caution. Synonym:
- /SUBDIRECTORIES.
-
- Even when the server does not provide recursive file lists,
- [M]GET /RECURSIVE forces Kermit to replicate any directory
- structure implied or expressed by the server's file list. For
- example:
-
- get somepath/somefile
-
- Gets the file named somefile from the server's somepath
- directory and puts it Kermit's current (or download) directory,
- whereas:
-
- get /recursive somepath/somefile
-
- creates the path locally and then puts the file in it.
- Similarly for MGET:
-
- mget */data/*
-
- downloads all the files in all the data subdirectories of all
- the subdirectories of the server's current directory and stores
- them locally in Kermit's current (or download) directory,
- whereas:
-
- mget /recursive */data/*
-
- re-creates the server's directory structure locally.
-
- The FTP protocol does not include explicit mechanisms for recursion,
- so Kermit builds upon what is available. Although an Internet draft
- describes a mechanism ("MLSD") that would allow protocol-driven
- recursion, similar to Kermit's File Attribute packets (circa 1984), it
- has not yet attained RFC or standard status, and servers are not yet
- widely available that offer this feature. In the meantime, the
- effectiveness of MGET /RECURSIVE depends on the FTP server
- implementation. If the server returns a recursive list in response to
- the standard NLST command (whose behavior is ill-defined), Kermit's
- FTP MGET /RECURSIVE command uses it to re-create the remote directory
- tree locally. If the server supports MLSD, C-Kermit 8.0.206 and Kermit
- 95 2.1 and later are able to sense it automatically and use it, as
- described below in [309]Section 3.11.
-
- The /BEFORE:, /AFTER:, /NOT-BEFORE:, and /NOT-AFTER: switches are not
- available for downloading because of the confusion with timezones.
- Would the given times be in the local timezone, the server's timezone,
- or GMT? The FTP server's directory listings show its own local times
- but since we don't know what timezone the server is in, there's no way
- to reconcile our local times with the server's. Similarly,
- /PERMISSIONS can't be preserved in downloads because FTP protocol
- provides no means of querying the server for a file's permission.
-
- Source-file disposition switches:
-
- /DELETE
- Each file that is downloaded successfully is to be deleted from
- the server. Requires the appropriate file access rights on the
- server.
-
- /SERVER-RENAME-TO:template
- Asks the server to rename each (remote) source file immediately
- after, and only if, it is sent correctly. See [310]PUT
- /SERVER-RENAME-TO: for details.
-
- Destination-file disposition switches:
-
- /TO-SCREEN
- Displays the incoming file on the screen rather than storing it
- on disk. If this switch is given, the /RENAME-TO and /MOVE-TO
- switches are ignored, the file-transfer display is suppressed,
- and the given file(s) is/are shown on the screen. Can be used
- with /FILTER, e.g.
-
- get /text /to-screen /filter:more oofa.txt
-
- In fact, you should always use /TO-SCREEN with /FILTER or
- /COMMAND when the command would result in displaying the
- incoming file on the screen; otherwise C-Kermit would have no
- way of knowing to suppress its file transfer display (since it
- can't be expected to know what the command or filter does).
-
- /RENAME-TO:template
- Each file that is downloaded is to be renamed as indicated if
- and only if it was received completely and without error. The
- template can be literal text or can contain variables that are
- evaluated for each file. For MGET, the text must contain
- variables; for GET it can be a literal string. The \v(filename)
- variable contains the name of the current file, so:
-
- ftp mget /rename-to:\v(filename).ok *
-
- causes each file that is successfully downloaded to have ".ok"
- appended to its name. For details see [311]Section 4.1 of the
- [312]C-Kermit 7.0 Update Notes.
-
- /MOVE-TO:text
- Just like /RENAME-TO:, except the text denotes the name of a
- directory to which successfully downloaded files are to be
- moved. If the directory does not exist, it is created.
-
- The file transfer display does not show the /MOVE-TO or /RENAME-TO
- value, since the incoming file has not yet been moved or renamed.
- _________________________________________________________________
-
- 3.6.2. Filename Collisions
-
- What should happen if an incoming file has the same name as an
- existing file in the same directory? By default, Kermit's FILE
- COLLISION setting applies: BACKUP, RENAME, UPDATE, DISCARD, etc, as
- described in [313]Using C-Kermit. Kermit's default FILE COLLISION
- setting is BACKUP (rename the existing file and store the incoming
- file under its own name) and therefore this is also the default FTP
- collision action.
-
- The name under which an incoming file is to be stored is determined as
- follows:
-
- * If an as-name was given, the as-name is used. Otherwise:
- * If the client and server platforms are alike or [314]FTP FILENAMES
- is set to LITERAL (or the /FILENAMES:LITERAL switch was given for
- this download), the incoming filename is used literally.
- Otherwise:
- * The incoming filename is converted to a form that is friendly to
- the local platform. For UNIX, for example, incoming filenames that
- are all uppercase (as they might be from, say, VMS or an IBM
- mainframe) are converted to lowercase.
-
- If the resulting name coincides with the name of a local file that
- already exists, we have a filename collision. Collisions are handled
- according to the currently selected collision action:
-
- SET FTP COLLISION { BACKUP, RENAME, UPDATE, DISCARD, APPEND, OVERWRITE
- }
- This establishes a filename collision for FTP, separate from
- the Kermit one. The initial FTP collision setting is inherited
- from Kermit's FILE COLLISION setting when the first FTP command
- is given, but subsequent changes to Kermit's FILE COLLISION
- setting do not affect the FTP COLLISION setting. SHOW FTP tells
- the current FTP COLLISION setting.
-
- FTP GET /COLLISION:{BACKUP,RENAME,UPDATE,DISCARD,APPEND,OVERWRITE}
- Overrides the current FTP COLLISION action for this download
- only.
-
- FTP GET /UPDATE
- This is equivalent to GET /COLLISION:UPDATE, and is included
- for symmetry with PUT /UPDATE
-
- FTP GET /UPDATE and /COLLISION:UPDATE mean to download only those
- files whose modification dates on the server are later than those on
- the client. Date-time comparisons are done in Coordinated Universal
- Time (UTC, GMT, ZULU). The command:
-
- FTP MGET /COLLISION:APPEND /AS-NAME:newfilename *.*
-
- Downloads all matching remote files into a single local file (in
- whatever order the server sends them).
- _________________________________________________________________
-
- 3.6.3. Recovery
-
- Recovery is available for downloads too, but there are some
- differences from the uploading case described in [315]Section 3.5.3:
-
- * The transfer must be in BINARY mode. It can not be in text mode,
- even if the FTP server is on the same kind of platform as Kermit,
- and even if there is no character-set translation. The original
- download must also have been in binary mode.
- * The FTP server must support the REST ("restart") directive.
- Unfortunately, this is not a standard command; at this writing, it
- is described only in an Internet Draft, not an RFC or Internet
- Standard, but nevertheless it is found in several popular FTP
- servers, such as [316]ProFTPD.
-
- Here's how download recovery works:
-
- * Kermit checks for conflicting switches, such as /UPDATE, /COMMAND,
- or /FILTER. If /RECOVER is given with these switches an error
- occurs.
- * The prevailing transfer mode (SET FTP TYPE) must be BINARY. If it
- is not, the /BINARY switch must have been included with the FTP
- [M]GET command.
-
- If the /RECOVER switch is accepted, then for each selected file:
-
- * A SIZE command is sent for the file (using its remote name). If
- the reply indicates the file was not found, or the SIZE command
- was not understood, or any other kind of error, recovery is
- canceled (i.e. the entire file is downloaded).
- * If the sizes of the two files are identical, the file is not sent.
- Otherwise:
- * Kermit sends the REST directive to the server, indicating the size
- of the local file. If the server responds affirmatively, Kermit
- opens the local file in append mode and appends the incoming data
- to it. Otherwise, recovery is canceled and the entire file is
- downloaded.
-
- The /RECOVER switch can be included with any FTP GET or MGET command,
- even if it specifies a group of files. This lets you resume an
- interrupted batch transfer from where it left off. The files that were
- already completely sent are skipped, the file that was interrupted is
- recovered, and the remaining files are uploaded. BUT... unlike with
- uploading, where this can be done with any mixture of text and binary
- files, when downloading, it can only be done if all the files are
- binary.
-
- It doesn't matter how the original partial file was downloaded -- FTP,
- Kermit, HTTP, Zmodem, etc: as long as the preconditions are met, it
- can be recovered with FTP [M]GET /RECOVER, or for that matter also
- with GET /RECOVER (using Kermit protocol).

- _________________________________________________________________
-
- 3.7. Translating Character Sets
-
- A possibly unique feature of Kermit's FTP client is its ability to
- convert character sets when transferring files in text mode,
- independent of the capabilites of the FTP server, as well as to
- translate the character sets of filenames regardless of transfer mode.
- For compatibility with existing FTP clients, and because there is a
- certain performance penalty, Kermit won't do this unless you ask for
- it. If you enable this feature, you need to inform Kermit of the
- character set (to be) used on the server and in some cases (explained
- below) also the local file character set. This discussion assumes you
- know a bit about character sets (as you must if you have to use them);
- see Chapter 16 of [321]Using C-Kermit for a detailed treatment. The
- Kermit commands for FTP character-set conversion are:
-
- SET FTP CHARACTER-SET-TRANSLATION { ON, OFF }
- Whether to translate character sets when transferring text
- files with FTP. OFF by default. Set this to ON to enable
- character-set translation for subsequent FTP uploads and
- downloads.
-
- SET FTP SERVER-CHARACTER-SET [322]name
- Text character set (to be) used by the server. Most FTP servers
- are ignorant of character sets, so all translations are done
- unilaterally by Kermit's FTP client. This means that when
- downloading files, you must know in advance the character-set
- used in the files you are downloading (and in their names).
- When uploading, you must specify the character-set to which
- local filenames and text-file contents are to be translated for
- transmission to the server. If you SET FTP
- CHARACTER-SET-TRANSLATION ON but do not specify an FTP
- SERVER-CHARACTER-SET, [323]UTF8 is used, since this is the new
- Internet standard international character set; it is upwards
- compatible with ASCII and it encompasses most written languages
- and therefore does not favor any particular group of people, as
- any other default would do. If you SET FTP SERVER-CHARACTER-SET
- to something (anything) when FTP CHARACTER-SET TRANSLATION is
- OFF, this also sets the latter ON.
-
- SET FILE CHARACTER-SET [324]name
- This is the regular Kermit (non-FTP-specific) command for
- identifying the character set (to be) used in local text files
- and filenames.
-
- TO REITERATE: If you SET FTP CHARACTER-SET TRANSLATION ON but do not
- specify an FTP SERVER-CHARACTER-SET, outbound text files are converted
- to UTF-8 and inbound text files are assumed to be UTF-8. If this is
- not appropriate, be sure to also specify the desired FTP
- SERVER-CHARACTER-SET.
-
- You can use "special" (non-ASCII) characters in filenames in all the
- client / server file management commands (FTP MKDIR, RMDIR, DIRECTORY,
- VDIRECTORY, DELETE, etc), and also in file-transfer commands. When
- giving commands such as FTP DIR (RDIR) and FTP PWD (RPWD), the reply
- is translated too, so you can read it. In this example, the client and
- server use entirely different codes to represent the special
- characters of German:
-
- C-Kermit> ftp xyzcorp.de /anonymous
- C-Kermit> set ftp server-character-set latin1
- C-Kermit> set file character-set german
- C-Kermit> rcd Städte
- C-Kermit> rpwd
- "/pub/ftp/Städte is current directory"
- C-Kermit> rdir
- -rw-rw---- 1 olaf 54018 Jan 6 17:58 Adenbüttel.txt
- -rw-rw---- 1 ursula 373 Jan 5 15:19 Aßlar.txt
- -rw-rw---- 1 gisbert 482 Jan 5 15:20 Blowatz.txt
- -rw-rw---- 1 gudrun 124 Jan 5 15:19 Böblingen.txt
- -rw-rw---- 1 olga 14348 Jan 7 14:23 Köln.txt
-
- When the client and server file systems use different character sets,
- you should take care to use only those characters that the two sets
- share in common when creating filenames or text-file contents. For
- example, PC code pages contain a lot line- and box-drawing characters,
- and sometimes "smart quotes", etc, that are not found in ISO standard
- 8-bit character sets. You should be especially careful to avoid using
- such characters in filenames.
-
- [ [325]C-Kermit Character Sets ]
- _________________________________________________________________
-
- 3.7.1. Character Sets and Uploading
-
- Kermit's PUT and MPUT commands include full file-scanning
- capabilities, as described in [326]Section 4. Thus if FTP
- CHARACTER-SET-TRANSLATION is ON and your character-set associations
- are set up appropriately, Kermit automatically switches on a per-file
- basis between text and binary mode, and for each text file between
- your chosen 7-bit text character set (e.g. ASCII or ISO 646 German),
- 8-bit text (e.g. Latin-1 or Japanese EUC), UCS-2, and UTF-8, and
- converts each of these automatically to the server character-set, and
- furthermore automatically differentiates between the Little and Big
- Endian forms of UCS-2, always sending in Big Endian form.
-
- WARNING: It is not advisable to use UCS-2 (or any Unicode
- transformation other than UTF-8) "on the wire", i.e. as a server
- character set. Most FTP servers are not able to cope with it, since
- it contains lots of 0 (NUL) characters. If you do use it, Kermit
- does not translate filenames to or from UCS-2, for reasons well
- known to C programmers (for example, UNIX APIs assume filename
- strings are NUL-terminated). [327]UTF-8 is the preferred (and
- standard) Unicode format for the Internet.
-
- FTP character-set translations differ from the regular Kermit ones by
- not restricting translations to a file-character-set /
- transfer-character-set pair. You can have Kermit's FTP client
- translate between any pair of character sets it knows about. You can
- see the list of supported character sets by typing either of the
- following:
-
- set ftp server-character-set ?
- set file character-set ?
-
- A typical list looks like this ([328]CLICK HERE for an explanation of
- the names):
-
- C-Kermit>set file char ? One of the following:
- ascii cp869-greek hebrew-7 mazovia-pc
- british cyrillic-iso hebrew-iso next-multinational
- bulgaria-pc danish hp-roman8 norwegian
- canadian-french dec-kanji hungarian portuguese
- cp1250 dec-multinational iso2022jp-kanji shift-jis-kanji
- cp1251-cyrillic dg-international italian short-koi
- cp1252 dutch jis7-kanji spanish
- cp437 elot927-greek koi8 swedish
- cp850 elot928-greek koi8r swiss
- cp852 euc-jp koi8u ucs2
- cp855-cyrillic finnish latin1-iso utf8
- cp858 french latin2-iso
- cp862-hebrew german latin9-iso
- cp866-cyrillic greek-iso macintosh-latin
- C-Kermit>
-
- Thus you can translate not only between private sets (like PC code
- pages) and standard ones (like Latin-1) as in Kermit protocol, but
- also between any given pair of private sets (e.g. CP852 and Mazovia).
- All conversions go through Unicode as the intermediate character set,
- resulting in a minimum of character loss, since Unicode is a superset
- of all other character sets known to Kermit.
-
- In addition to the SET commands listed above, the FTP PUT and MPUT
- commands include switches that apply only to the current command:
-
- /LOCAL-CHARACTER-SET:name
- /SERVER-CHARACTER-SET:name
- Use these switches to force a particular translation. These
- switches override the global FTP CHARACTER-SET-TRANSLATION and
- SERVER-CHARACTER-SET settings and also character-set
- differentiation by file scanning for the duration of the PUT or
- MPUT command. The file scan is still performed, however, to
- determine whether the file is text or binary; thus these
- switches do not affect binary files unless you also include the
- /TEXT switch to force all files to be treated as text.
-
- In other words, if you include one or both of these switches with a
- PUT or MPUT command, they are used. Similarly, the /TRANSPARENT switch
- disables character-set translation for the PUT or MPUT command despite
- the prevailing FTP CHARACTER-SET-TRANSLATION and SERVER-CHARACTER-SET
- settings.
-
- When uploading, the FILE CHARACTER-SET setting is ignored unless you
- have forced Kermit not to [329]scan local files by including a /TEXT
- or /BINARY switch with your [M]PUT command, or by disabling automatic
- text/binary switching in some other way.
-
- Examples:
-
- 1. Suppose you have a CP852 (East European) text file that you want
- to upload and store in ISO Latin Alphabet 2 encoding:
- ftp put /local-char:cp852 /server-char:latin2 magyar.txt
- 2. Suppose you always want your text files converted to Latin-2 when
- uploading with FTP. Then put:
- set ftp server-character-set latin2
- in your Kermit customization file, and then you can omit the
- /SERVER-CHARACTER-SET: switch from your FTP PUT commands:
- ftp put /local-char:cp852 magyar.txt
- 3. Now suppose that all the text files on your PC are written in
- Hungarian, but they have a variety of encodings, and you don't
- want to have to include the /LOCAL-CHARACTER-SET: switch on every
- FTP PUT command, or (more to the point) you want to be able to
- send a mixture of these files all at once. Put these commands in
- your Kermit customization file:
- set ftp server-character-set latin2 ; ISO 8859-2
- set file default 7-bit-character-set hungarian ; ISO 646 Hungarian
- set file default 8-bit-character-set cp852 ; PC East European Code Page
- and now PUT and MPUT will automatically detect and switch among
- ISO 646 Hungarian, Code Page 852, UTF-8, and UCS-2 encodings,
- translating each one to Latin-2 for uploading:
- ftp put *.txt
-
- And since binary files are also detected automatically, the latter can
- be simplified to:
-
- ftp put *
-
- even when "*" matches a diverse collection of binary and text files,
- because translations are skipped automatically for binary files.
- _________________________________________________________________
-
- 3.7.2. Character Sets and Downloading
-
- The commands and switches are the same as for uploading, but automatic
- character-set switching works differently, since Kermit can't scan the
- server files in advance. Instead, the transfer mode (text or binary)
- is based on the filenames; each name is compared with Kermit's list of
- text name patterns and binary name patterns. If the name matches a
- binary pattern (for example, if the filename is oofa.tar.gz and one of
- the filename patterns is "*.gz"), the file is downloaded in binary
- mode; otherwise if it matches a text pattern (e.g. oofa.txt matches
- "*.txt"), it is transferred in text ("ascii") mode. Otherwise, it is
- transferred in the prevailing FTP TYPE.
-
- In C-Kermit 8.0, the pattern lists used with FTP GET are not the same
- lists used with Kermit transfers, and can not be viewed with SHOW
- PATTERNS, nor adjusted with ADD and REMOVE TEXT-PATTERNS and
- BINARY-PATTERNS, or SET FILE TEXT-PATTERNS and BINARY-PATTERNS.
- Configuration of the FTP patterns list will be added in a future
- release.
-
- Examples:
-
- get /server-char:latin1 /local-char:cp850 Grüße.txt
- In this command, the filename contains special characters,
- which you enter using whatever character set your local
- computer uses, in this case PC Code Page 850 (cp850). The
- command tells Kermit (in case it didn't know already from its
- FILE CHARACTER-SET setting) that the local character set is
- cp850 and the server's character-set is ISO 8859-1 Latin
- Alphabet 1 (latin1). Kermit translates the filename from cp850
- to latin1 and sends the latin1 name to the server. Since it's a
- text file (matches "*.txt"), its contents are translated to
- cp850 on arrival, and it is saved with a cp850 name.
-
- mget /text /server:latin1 /local:utf8 *.txt
- This command:
-
- + Tells C-Kermit that the server's files are encoded in ISO
- 8859-1 Latin Alphabet 1.
- + Tells C-Kermit to translate the incoming files into Unicode
- UTF-8 for storage.
- + Asks the server to send all ".txt" files in text mode.
-
- mget /server:latin1 /local:utf8 *
- Tells Kermit to get all files from the server's directory,
- switching between text and binary mode based on the filename.
- The names of all the files are translated (to UTF-8 in this
- case), but contents are translated (also to UTF-8) only for
- text files.
-
- Note that any pair of 8-bit character sets is likely to have some
- incompatibilities. Any characters in the source file that do not have
- equivalents in the destination file's character set are converted to
- question marks. This applies to both filenames and to text file
- contents.
-
- Also note that the server's ability to accept special characters in
- filenames depends on the particular server. For example:
-
- get Grüße.txt
-
- works with WU-FTPD, but:
-
- mget Grüß*.txt
-
- does not.

- 3.7.3. RFC2640
-
- [330]RFC2640, July 1999, specifies a method by which the FTP client
- and server can negotiate the use of UTF8. However, RFC2640-capable
- servers are rare to nonexistent at this writing, and in any case you
- don't need them to be able to transfer text in UTF8. C-Kermit lets you
- upload and download text files in any character set it knows about,
- converting to or from any other character set it knows about, without
- the knowledge, permission, or cooperation of the server, and
- regardless of its capabilities.

-
- 3.8. FTP Command Shortcuts
-
- C-Kermit's FTP client coexists with other C-Kermit functions by
- requiring the "ftp" prefix for each FTP-related command: FTP OPEN, FTP
- GET, FTP BYE, and so on. For interactive use, however, this can be
- rather awkward and sometimes surprising, for example when a GET
- command starts a Kermit GET rather than an FTP GET. In fact, many
- Kermit commands might just as easily apply to an FTP connection: GET,
- PUT (SEND), BYE, and CLOSE. The following command lets you choose how
- these commands are interpreted:
-
- SET GET-PUT-REMOTE { AUTO, KERMIT, FTP }
- Controls the orientation of GET, PUT, REMOTE and other
- file-transfer and client/server commands that might apply to
- either Kermit or FTP. The default setting is AUTO, meaning that
- these commands apply to FTP if an FTP connection is open, and
- to Kermit otherwise. KERMIT means they always apply to Kermit,
- FTP means they always apply to FTP.
-
- Here is a complete list of affected commands:
-
- Kermit Command FTP Equivalent
- (none) FTP [ OPEN ]
- LOGIN FTP USER
- LOGOUT FTP RESET
- BYE FTP BYE
- FINISH FTP BYE
- CLOSE FTP BYE
- HANGUP FTP BYE
- BINARY FTP TYPE BINARY
- TEXT (or ASCII) FTP TYPE ASCII
- SEND (or PUT) FTP PUT
- MSEND (or MPUT) FTP MPUT
- RESEND FTP PUT /RECOVER
- CSEND FTP PUT /COMMAND
- GET FTP GET
- MGET FTP MGET
- REGET FTP GET /RECOVER
- REMOTE HELP (RHELP) FTP HELP
- REMOTE CD (RCD) FTP CD (CWD)
- REMOTE PWD (RPWD) FTP PWD
- REMOTE DIRECTORY (RDIR) FTP DIRECTORY
- REMOTE DELETE (RDEL) FTP DELETE
- REMOTE MKDIR (RMKDIR) FTP MKDIR
- REMOTE RMDIR (RRMDIR) FTP RMDIR
- REMOTE RENAME (RRENAME) FTP RENAME
- REMOTE TYPE (RTYPE) FTP TYPE
- REMOTE EXIT (REXIT) FTP BYE
-
- The commands in the right-hand column always access FTP. The commands
- in the left column can access either Kermit protocol or FTP:
-
- * When GET-PUT-REMOTE is set to KERMIT, or to AUTO when there is no
- FTP connection, the commands in the left-hand column access Kermit
- protocol, and those right-hand column are required for FTP.
- * When GET-PUT-REMOTE is set to FTP, or to AUTO when there is an
- active FTP connection, the commands in the left-hand column access
- the FTP connection and can not be used to access Kermit protocol.
- In this case, if you want to be able to use both Kermit protocol
- and the FTP connection, you must SET GET-PUT-REMOTE KERMIT, and
- then use the FTP commands in the right-hand column to access the
- FTP connection.
-
- Note that file-management commands such as DIRECTORY, DELETE, CD, PWD,
- MKDIR, RMDIR, HELP, RENAME, COPY, TYPE, and so on, always apply
- locally, no matter what kind of connection you have. This is the
- opposite of most FTP clients, where these commands are intended for
- the server, and require an "L" prefix for local execution (e.g. "dir"
- gets a directory listing from the server, "ldir" gets a local
- directory listing). To illustrate with the CD command and a typical
- UNIX FTP client:
-
- Client Server Change Local Directory Change Remote Directory
- FTP FTP lcd cd (cwd)
- Kermit Kermit cd rcd, remote cd
- Kermit FTP cd ftp cd, rcd, remote cd
-
- Also note that not all REMOTE commands are useful with FTP, since FTP
- servers do not offer the corresponding functions. These include:
-
- * REMOTE ASSIGN - FTP servers don't have variables
- * REMOTE COPY - FTP servers don't copy files
- * REMOTE HOST - FTP servers don't execute host (shell) commands
- * REMOTE KERMIT - FTP servers don't execute Kermit commands
- * REMOTE PRINT - FTP servers don't print files
- * REMOTE QUERY - FTP servers don't have variables
- * REMOTE SET - FTP servers don't have Kermit settings
- * REMOTE WHO - FTP servers don't send user lists
-
- Finally note that command shortcuts do not apply to the HELP command.
- For help about an FTP command, use (for example) "help ftp delete",
- not "help delete" or "help rdelete".

-
- 3.9. Dual Sessions
-
- You can have an FTP session open at the same time as a regular Kermit
- SET LINE or SET HOST (terminal) session. In this case, the default SET
- GET-PUT-REMOTE AUTO setting should ensure that all "two-faced"
- commands like GET, PUT, REMOTE, HANGUP, BYE, etc, apply to the Kermit
- session, and all commands for the FTP session must include the FTP
- prefix. To be absolutely certain, you can use SET GET-PUT-REMOTE
- KERMIT.
-
- ftp foo.bar.baz.com
- if fail ...
- (log in)
- set host foo.bar.baz.com
- if fail ...
- (log in)
-
- Now you have both an FTP and Telnet connection to the same host (of
- course they could also be to different hosts, and you could also have
- a direct or dialed serial connection instead of a Telnet connection).
- Now assuming you have a Kermit server on the far end of the Kermit
- connection:
-
- rcd incoming ; Changes Kermit server's directory (= REMOTE CD)
- ftp cd incoming ; Changes FTP server's directory
- put oofa.txt ; Sends a file on the Kermit connection
- ftp put oofa.txt ; Sends a file on the FTP connection
- bye ; Shuts down the Kermit connection
- ftp bye ; Shuts down the FTP connection
-
- Note that PUT and SEND are synonyms for both FTP and Kermit
- connections.
-
- You can also establish dual sessions on the Kermit command line:
-
- kermit -j host1 -9 host2
-
- This makes a Telnet connection to host1 and an FTP connection to
- host2.

-
- 3.10. Automating FTP Sessions
-
- Most of Kermit's scripting features can be used to make and control
- FTP sessions: FOR and WHILE loops, IF-ELSE and SWITCH constructions,
- variables, arrays, built-in functions, and all the rest. You can't use
- INPUT, MINPUT, OUTPUT, CLEAR, or SCRIPT on an FTP session, but these
- are not needed since the FTP protocol is well defined.
-
- [343]CLICK HERE for an FTP scripting tutorial.
-
- 3.10.1. FTP-Specific Variables and Functions
-
- The following variable tells whether an FTP connection is open:
-
- \v(ftp_connected)
- 1 if there is an active FTP connection, 0 if there isn't.
-
- The FTP OPEN command sets:
-
- \v(ftp_host)
- The host to which the most recent FTP connection was made.
-
- \v(ftp_security)
- The security method negotiated for the current FTP session. The
- value is "NULL" when no security is used. See [344]3.2. Making
- Secure FTP Connections.
-
- \v(ftp_server)
- The OS type (UNIX, VMS, etc) of the FTP server host.
-
- The FTP USER command (or FTP OPEN /USER:, or FTP with automatic login)
- sets:
-
- \v(ftp_loggedin)
- 1 if you are logged in to an FTP server, 0 if you are not.
-
- The current COMMAND-PROTECTION-LEVEL and DATA-PROTECTION-LEVEL values
- are reflected in:
-
- \v(ftp_cpl)
- \v(ftp_dpl)
- The values are "clear", "confidential", "safe" or "private".
- See [345]3.2. Making Secure FTP Connections.
-
- The FTP GET-PUT-REMOTE setting is reflected in:
-
- \v(ftp_getputremote)
- The values are "auto", "ftp", or "kermit".
-
- Every FTP command sets the \v(success) variable, as well as the
- following two FTP-specific variables:
-
- \v(ftp_code)
- The standardized numeric FTP protocol code from the server's
- response to the last client command, a 3-digit decimal number
- defined in [346]RFC959. Briefly:
-
- 1xx = Positive Preliminary Reply
- 2xx = Positive Completion Reply
- 3xx = Positive Intermediate Reply
- 4xx = Transient Negative Completion Reply
- 5xx = Permanent Negative Completion Reply
-
- \v(ftp_message)
- The text message, if any, from the server's response to the
- last client command. If the most recent response had multiple
- lines, this variable has only the final line. These messages
- are not standardized and vary in format and content from server
- to server. Synonym: \v(ftp_msg).
-
- FTP file transfers set the regular Kermit transfer status variables:
-
- \v(cps) Characters per second of most recent transfer.
- \v(filespec) File specification used in most recent transfer.
- \v(fsize) Size of file most recently transferred.
- \v(tfsize) Total size of file group most recently transferred.
- \v(xferstatus) Status of most recent transfer (0 = success, 1 = failure).
- \v(tftime) Elapsed time of most recent transfer, in seconds.
-
- During an FTP transfer, the per-file variables are:
-
- \v(filename) Name of current file.
- \v(filenumber) Ordinal file number in group (1, 2, 3, ...)
- _________________________________________________________________
-
- 3.10.2. Examples
-
- Let's begin with a simple example showing how to log in, send some
- files, and log out:
-
- define error if fail { ftp bye, stop 1 Error: \%1 }
- set transact brief
- log t
- ftp ftp.xyzcorp.com /anonymous
- if fail stop 1 Connection failed
- if not \v(ftp_loggedin) stop 1 Login failed
- ftp cd incoming
- error {ftp cd}
- cd upload
- error {local cd}
- ftp put /delete *
- error {put}
- ftp bye
-
- First we define an error handling macro to be used after the
- connection is made. Then we set up a brief-format transaction log to
- keep a record of our file transfers. Then we make a connection to the
- host and log in anonymously. The "if fail" command checks whether the
- connection was made. The "if not" command checks whether login was
- successful. Obviously the script should not continue unless both tests
- succeed.
-
- Next we change to the server's 'incoming' directory and to our own
- 'upload' directory, and send all the files that are in it (they can be
- any mixture of text and binary files), deleting each source file
- automatically after it is successfully uploaded. Each of these
- operations is checked with the ERROR macro, which prevents the script
- from continuing past a failure.
-
- Finally we close the FTP session with the "bye" command.
-
- Just like any other Kermit script, this one can be used in many ways:
-
- * It can be stored in a file, and Kermit can be told to TAKE the
- file.
- * In UNIX, it can be a "[347]kerbang" script and therefore run
- directly from the shell prompt or as a cron job.
-
- We could have used command shortcuts like "rcd", "put", and "bye", but
- since they can be ambiguous under certain circumstances, it is better
- to avoid them in scripts; they are intended mainly for convenience
- during interactive use. However, if you wish to use the shortcuts in a
- script, you can do it this way (error handling omitted for brevity):
-
- local \%t ; Declare a local temporary veriable
- assign \%t \v(ftp_getputremote) ; Save current FTP GET-PUT-REMOTE setting
- set ftp get-put-remote ftp ; Choose FTP orientation
- ftp xyzcorp.com /anonymous ; Open an FTP connection
- get oofa.txt ; GET a file
- put foo.bar ; PUT a file
- rdel yesterday.log ; Delete a file on the server
- bye ; Log out and disconnect from server.
- set ftp get-put-remote \%t ; Restore previous GET-PUT-REMOTE setting
-
- Of course, FTP scripts can also be written as macros. This lets you
- pass parameters such as hostnames, usernames, and filenames to them:
-
- define doftpget {
- if < \v(argc) 4 end 1 Usage: \%0 host user remotefile [ localfile ]
- ftp \%1 /user:\%2
- if fail end 1 FTP OPEN \%1 failed
- if not \v(ftp_loggedin) end 1 FTP LOGIN failed
- ftp get {\%3} {\%4}
- if fail end 1 FTP GET \%3 failed
- ftp bye
- }
-
- Add this definition to your Kermit customization file, and it will
- always be available when you start Kermit. This macro lets you
- download a file with FTP by giving a single command, e.g.:
-
- doftpget xyzcorp.com anonymous oofa.txt
- _________________________________________________________________
-
- 3.10.3. Automating Secure FTP Sessions
-
- Often when making secure connections, you are prompted interactively
- for certain information or permission to proceed. These prompts can
- stop an automated procedure. To avoid them, you must give the
- appropriate commands to disable them, and/or supply the prompted-for
- information beforehand. Here are a few hints:
-
- * Make sure that SET TAKE ERROR and SET MACRO ERROR are both OFF.
- This is the default, but in case you have set either one of these
- ON in your script or initialization file, this makes the script
- halt on any kind of error. Normally you would want to check each
- operation for success or failure and take appropriate action.
- * On SSL and TLS connections, you may be asked whether it is OK to
- proceed with a connection to server that presents a self-signed
- certificate. You can use the SET AUTHENTICATION SSL (or TLS)
- VERIFY or SET AUTH SSL (or TLS) CERTS-OK commands to avoid this
- prompt by not requesting a certificate from the peer.
- * (More to be added...)

- 3.11. Advanced FTP Protocol Features
-
- The remainder of the FTP documention (through the end of Section 3) is
- new to C-Kermit 8.0.206, but we leave it in black to prevent
- headaches. Except for titles.
- * [353]TERMINOLOGY
- * [354]FEATURE NEGOTIATION
- * [355]USING MGET: NLST VERSUS MLSD
- * [356]EXAMPLES
- * [357]REFERENCES
-
- The new releases of [358]C-Kermit (8.0.206) and [359]Kermit 95 (2.1)
- support new FTP protocol features from RFC 2389 as well as most of
- what's in the Elz and Hethmon Extensions to FTP Internet Draft (see
- [360]References). Some of these features, such as SIZE (request a
- file's size), MDTM (request file's modification time), and REST
- (restart interrupted transfer) have been widely implemented in FTP
- clients and servers for years (as well as in the initial release of
- the Kermit FTP clients). Others such as FEAT and MLSD are rarely seen
- and are new to the upcoming Kermit releases. TVFS (Trivial Virtual
- File Store) is supported implicitly, and the UTF-8 character-set is
- already fully supported at the protocol and data-interchange level.
-
- For Kermit users, the main benefit of the new FTP protocol extensions
- is the ability to do recursive downloads. But the extensions also
- introduce complications and tradeoffs that you should be aware of. Of
- course Kermit tries to "do the right thing" automatically in every
- case for backwards compatibility. But (as noted later) some cases are
- inherently ambiguous and/or can result in nasty surprises, and for
- those situations new commands and switches are available to give you
- precise control over Kermit's behavior, in case the defaults don't
- produce the desired results.
- _________________________________________________________________
-
- 3.11.1. Terminology Command-line FTP clients such as Kermit (as well
- as the traditional FTP programs found on Unix, VMS, ..., even Windows)
- have commands like PUT, MPUT, GET, MGET, and BYE, which they convert
- into zero or more FTP protocol commands, such as NLST, RETR, QUIT. For
- clarity, we'll use "command" to refer to commands given by the user to
- the FTP client, and "directive" for FTP protocol commands sent by the
- FTP client to the FTP server.
- _________________________________________________________________
-
- 3.11.2. Feature Negotiation New FTP protocol features are negotiated
- by the client sending a FEAT directive and the server responding with
- a list of (new) features it supports, or else with an error indication
- if it does not support the FEAT directive at all, in which case the
- client has to guess which new features it supports (Kermit guesses
- that it supports SIZE and MDTM but not MLST). Note that the MLST
- feature includes MLSD, which is not listed separately as a feature.
-
- Guessing is nice when it works, but sometimes it doesn't, and some FTP
- servers become confused when you send them a directive they don't
- understand, or they do something you didn't want, sometimes to the
- point of closing the connection. For this reason, Kermit lets you
- override default or negotiated features with the following new
- commands:
-
- FTP { ENABLE, DISABLE } FEAT
- Enables or disables the automatic sending of a FEAT directive
- upon connection to an FTP server. Note that
- FTP [ OPEN ] /NOINIT also inhibits sending the FEAT directive
- (and several others) for the connection being OPEN'd, but
- without necessarily disabling FEAT for subsequent connections
- in the same Kermit instance. FEAT is ENABLED by default, in
- which case many FTP servers are likely to reply:
-
-500 'FEAT': command not understood
-
- which is normally harmless (but you never know). (In C-Kermit
- 8.0.208, this error message is suppressed unless you SET FTP
- DEBUG ON.)
-
- FTP ENABLE { MDTM, MLST, SIZE }
- Enables the given directive for implicit use by the FTP GET and
- MGET commands in case it has been disabled or erroneously
- omitted by the server in its FEAT response. Note: MLSD can be
- used in the FTP ENABLE and DISABLE commands as a synonym for
- MLST. YOU MUST GIVE THIS COMMAND AFTER MAKING THE FTP
- CONNECTION.
-
- FTP DISABLE { MDTM, MLST, SIZE }
- Disables implicit use of the given directive by GET or MGET in
- case it causes problems; for example, because it makes
- multifile downloads take too long or the server announces it
- erroneously or misimplements it. Use DISABLE FEAT before making
- a connection to prevent Kermit from sending the FEAT directive
- as part of its initial sequence. Note that disabling FEAT,
- SIZE, or MDTM does not prevent you from executing explicit FTP
- FEATURES, FTP SIZE, or FTP MODTIME commands. Also note that
- disabling SIZE prevents PUT /RESTART (recovery of interrupted
- uploads) from working. YOU MUST GIVE THIS COMMAND AFTER MAKING
- THE FTP CONNECTION.
-
- To enable or disable more than one feature, use multiple FTP ENABLE or
- FTP DISABLE commands. The SHOW FTP command shows which features are
- currently enabled and disabled.
-
- FTP FEATURES
- This command sends a FEAT directive to the server. In case you
- have been disabling and enabling different features, this
- resynchronizes Kermit's feature list with the server's. If the
- server does not support the FEAT directive, Kermit's feature
- list is not changed.
-
- FTP OPTIONS directive
- Informational only: the server tells what options, if any, it
- supports for the given directive, e.g. MLST. Fails if the
- server does not support the OPTS directive or if the directive
- for which options are requested is not valid. The directive is
- case-insensitive.
-
- FTP SIZE filename
- Sends a SIZE directive to the server for the given file. The
- filename must not contain wildcards. The server responds with
- an error if the file can't be found, is not accessible, or the
- SIZE directive is not supported, otherwise with the length of
- the file in bytes, which Kermit displays and also makes
- available to you in its \v(ftp_message) variable. If the
- directive is successful, Kermit (re-)enables it for internal
- use by the GET and MGET directives on this connection.
-
- FTP MODTIME filename
- Works just like the SIZE directive except it sends an MDTM
- directive. Upon success, the server sends modification
- date-time string, which Kermit interprets for you and also
- makes available in its \v(ftp_message) variable.
-
- Whenever a SIZE or MDTM directive is sent implicitly and rejected by
- the server because it is unknown, Kermit automatically disables it.
- _________________________________________________________________
-
- 3.11.3. Using MGET: NLST versus MLSD When you give an MGET command to
- an FTP client, it sends a request to the FTP server for a list of
- files, and then upon successful receipt of the list, goes through it
- and issues a RETR (retrieve) directive for each file on the list (or
- possibly only for selected files).
-
- With the new FTP protocol extensions, now there are two ways to get
- the list of files: the NLST directive, which has been part of FTP
- protocol since the beginning, and the new MLSD directive, which is new
- and not yet widely implemented. When NLST is used and you give a
- command like "mget *.txt", the FTP client sends:
-
-NLST *.txt
-
- and the server sends back a list of the files whose names match, e.g.
-
-foo.txt
-bar.txt
-baz.txt
-
- Then when downloading each file, the client sends SIZE (if it wants
- have a percent-done display) and MDTM (if it wants to set the
- downloaded file's timestamp to match that of the original), as well as
- RETR (to retrieve the file).
-
- But when MLSD is used, the client is not supposed to send the filename
- or wildcard to the server; instead it sends an MLSD directive with no
- argument (or the name of a directory), and the server sends back a
- list of all the files in the current or given directory; then the
- client goes through the list and checks each file to see if it matches
- the given pattern, the rationale being that the user knows only the
- local conventions for wildcards and not necessarily the server's
- conventions. So with NLST the server interprets wildcards; with MLSD
- the client does.
-
- The interpretation of NLST wildcards by the server is not
- necessarily required or even envisioned by the FTP protocol
- definition (RFC 959), but in practice most clients and servers work
- this way.
-
- The principal advantage of MLSD is that instead of sending back a
- simple list of filenames, it sends back a kind of database in which
- each entry contains a filename together with information about the
- file: type, size, timestamp, and so on; for example:
-
-size=0;type=dir;perm=el;modify=20020409191530; bin
-size=3919312;type=file;perm=r;modify=20000310140400; bar.txt
-size=6686176;type=file;perm=r;modify=20001215181000; baz.txt
-size=3820092;type=file;perm=r;modify=20000310140300; foo.txt
-size=27439;type=file;perm=r;modify=20020923151312; foo.zip
-(etc etc...)
-
- (If the format of the file list were the only difference between NLST
- and MLSD, the discussion would be finished: it would always be better
- to use MLSD when available, and the MGET user interface would need no
- changes. But there's a lot more to MLSD than the file-list format;
- read on...)
-
- The client learns whether the server supports MLSD in FEAT exchange.
- But the fact that the server supports MLSD doesn't mean the client
- should always use it. It is better to use MLSD:
-
- * On connections where the server imposes a time penalty for every
- command, e.g. the Red Hat Rawhide server. With MLSD, the client
- needs to send only one command (RETR) per file, whereas NLST
- requires three (SIZE, RETR, and MDTM). Suppose there is a
- 30-second delay for each command and 1000 files are to be fetched;
- in that case, MLSD saves 60,000 seconds = 1000 minutes = 16 hours
- and 40 minutes.
- * For recursive downloads since there is no dependable way to
- download directory trees with NLST.
-
- But it is better to use NLST:
-
- * If you want only a couple short files out of a large directory. In
- this case, NLST is the better choice since the server sends a list
- of only the files you want, not a list of (say) a million files,
- which can make a big difference on slow connections. For example,
- suppose your wildcard matches three files of 1K each, but the
- million-file listing is 80MB long, and your connection is through
- a modem. The overhead of using MLSD is practically infinite.
- * If the server supports wildcarding features not known to the
- client, but that can be used to achieve desirable effects
- otherwise unobtainable, such as "[dir...]*.txt" in VMS or AOS/VS
- "except" clauses.
- * If you have been given a wildcard string by an FTP site
- administrator for fetching a specific group of files out of a
- larger directory, e.g. "mget ck[cuw]*.[cwh] makefile", that is
- expected to work with any client (an FTP site administrator can't
- be expected to know the wildcard syntax of every FTP client).
-
- But when using MLSD there are complications:
-
- * MLSD wants either a blank argument (meaning the current directory)
- or else the name of a specific directory. The client must not send
- it a wildcard or a filename.
- * But if the user's command is "mget xxx", how does the client know
- whether to send "xxx" in the MLSD directive? It might be the name
- of a directory on on the server, in which case it should be sent,
- or it might be the name of a file on the server (or a wildcard),
- in which case it must not be sent. Since the client knows its own
- wildcard syntax, then in most cases it would be right to send
- "MLSD" with no argument if xxx is wild, and to send "MLSD xxx" if
- it is not.
- * But suppose the server's file system allows filename characters
- that correspond with the client's wildcard syntax? For example:
- "[abc]" could be either a valid VMS directory name or a wildcard
- pattern used by the FTP client. What should the client do with
- "mget [abc]"? In this case there must be a way for the user to
- force sending the MGET argument as the MLSD argument.
- * If "xxx" is a regular file in the server's current directory,
- "mget xxx" works with NLST but not with MLSD.
-
- To further complicate matters, NLST can (in theory) work just like
- MLSD: if sent with a blank argument or a directory name, it is
- supposed to return a complete list of files in the current or given
- directory, which the client can match locally against some pattern. It
- is not known if any FTP server or client does this but nevertheless,
- it should be possible since this behavior can be inferred from RFC
- 959.
-
- In view of these considerations, and given the need to preserve the
- traditional FTP client command structure and behavior so the software
- will be usable by most people:
-
- 1. The MGET command should produce the expected result in the common
- cases, regardless of whether NLST or MLSD is used underneath.
- 2. For anomalous cases, the user needs a way to control whether the
- MGET argument is sent to the server or kept for local use.
- 3. At the same time, the user might need a way to send a directory
- name to the server, independent of any wildcard pattern.
- 4. The user needs a way to force NLST or MLSD for a given MGET
- command.
-
- By default, Kermit's MGET command uses MLSD if MLST is reported by the
- server in its FEAT list. When MLSD is used, the filespec is sent to
- the server if it is not wild (according to Kermit's own definition of
- "wild" since it can't possibly know the server's definition). If the
- filespec is wild it is held for local use to select files from the
- list returned by the server. If MLST is not reported by the server or
- is disabled, Kermit sends the MGET filespec with the NLST directive.
-
- The default behavior can be overridden globally with FTP DISABLE MLST,
- which forces Kermit to use NLST to get file lists. And then for
- situations in which MLSD is enabled, the following MGET switches can
- be used to override the defaults for a specific MGET operation:
-
- /NLST
- Forces the client to send NLST. Example:
-
-mget /nlst foo.*
-
- /MLSD
- Forces the client to send MLSD (even if MLST is disabled).
- Example:
-
-mget /mlsd foo.*
-
- /MATCH:pattern
- When this switch is given, it forces the client to hold the
- pattern for local use against the returned file list. If a
- remote filespec is also given (e.g. the "blah" in "mget
- /match:*.txt blah"), then it is sent as the NLST or MLSD
- argument, presumably to specify the directory whose files are
- to be listed. When the /MATCH switch is not given, the MGET
- filespec is sent to the server if the directive is NLST or if
- the filespec is not wild. Examples:
-
- Command: With NLST: With MLSD:
- mget NLST MLSD
- mget *.txt NLST *.txt MLSD
- mget foo NLST foo MLSD foo
- mget /match:*.txt NLST MLSD
- mget /match:*.txt foo NLST foo MLSD foo
-
- In other words, the pattern is always intepreted locally unless MGET
- uses NLST and no /MATCH switch was given.

-
- 3.11.4. Examples
-
- 3.11.4.1. Downloading a Single File
-
- There are no choices here, just use the FTP GET command. Kermit always
- sends the RETR directive, and possibly SIZE and/or MDTM. The small
- advantage of using MLST in this case is outweighed by the risk and
- effort of coding a special case.
-
- 3.11.4.2. Downloading a Group of Files from a Single Directory
-
- This case presents tradeoffs, especially on slow connections:
-
- * For downloading all or most of the files in a directory, MLSD is
- better because it eliminates the need to send SIZE and MDTM for
- each file. No special actions are required in this case; Kermit
- uses MLSD automatically if the server supports it (unless you have
- disabled it).
- * For a small number of files from a large directory, NLST is better
- because it bypasses downloading of a potentially huge file list
- prior to the files themselves. If you have a connection to a
- server that supports MLSD, use the /NLST switch to force NLST:
-
-mget /nlst t[1234].h
-
- * If the server supports MLSD but does not support separate SIZE or
- MDTM directives, and you need the size and/or timestamp
- information, MLSD is better; no special actions required.
- * If the server supports MLSD but does not support the "size" and
- "modify" facts, but it does support the SIZE or MDTM directives,
- and you need the size and/or timestamp information, NLST is
- better.
-
- 3.11.4.3. Downloading a Directory Tree
-
- MLSD is the only choice for recursive downloads; they rarely, if ever,
- work with NLST (the few cases where they do work rely on
- extra-protocol "secret" notations for the NLST argument). No special
- actions are required to force MLSD when the server supports it, unless
- you have disabled it. Examples:
-
- MGET /RECURSIVE
- This tells the server to send all files and directories in the
- tree rooted at its current directory.
-
- MGET /RECURSIVE *.txt
- This tells the server to send all *.txt files in the tree
- rooted at its current directory.
-
- MGET /MLSD /RECURSIVE *.txt
- Same as the previous example but forces Kermit to send MLSD in
- case it was disabled, or in case the server is known to support
- it even though it did not announce it in its FEAT listing.
-
- MGET /RECURSIVE /MATCH:*.zip archives
- Tells the server to send all ZIP files in the tree rooted at
- its "archives" directory.
-
- MGET /RECURSIVE /MATCH:* [abc]
- The server is running on VMS and you want it to send all the
- files in the directory tree rooted at [ABC]. But since "[abc]"
- looks just like a wildcard, you have to include a /MATCH:
- switch to force Kermit to send "[abc]" as the MLSD argument.
-
- In all cases in which the /RECURSIVE switch is included, the server's
- tree is duplicated locally.
-
- Although MLSD allows recursion and NLST does not, the MLSD
- specification places a heavy burden on the client; the obvious,
- straightforward, and elegant implementation (depth-first, the one
- that Kermit currently uses) requires as many open temporary files
- as the server's directory tree is deep, and therefore client
- resource exhaustion -- e.g. exceeding the maximum number of open
- files -- is a danger. Unfortunately MLSD was not designed with
- recursion in mind. (Breadth-first traversal could be problematic
- due to lack of sufficient navigation information.)
-
- Of course all of Kermit's other MGET switches can be used too, e.g.
- for finer-grained file selection (by date, size, etc), for moving or
- renaming files as they arrive, to override Kermit's automatic per-file
- text/binary mode switching, to pass the incoming files through a
- filter, to convert text-file character sets, and so on.
-
- 3.11.4.4. NLST/MLSD Summary Table
-
- Here's a table summarizing MGET behavior when the server supports both
- NLST and MLSD. /NLST and /MLSD switches are included for clarity to
- indicate which protocol is being used, and the expected effects. In
- practice you can omit the /NLST and /MLSD switches and the Kermit
- client chooses the appropriate or desired protocol as described above.
- Sample commands presume a Unix file system on the server, but of
- course the server can have any file system or syntax at all.
-
- User's Command FTP Sends Remarks
- mget /nlst NLST Gets a list of all the files in the server's current
- and downloads each file. The list includes names only, so Kermit also
- must send SIZE and MDTM directives if size and timestamp information
- is required (this is always true of NLST). Sending NLST without an
- argument is allowed by the RFC959 NLST definition and by the Kermit
- FTP client, but might not work with other clients, and also might not
- work with every server.
- mget /nlst foo NLST foo If "foo" is a directory, this gets a list of
- all the files from the server's "foo" directory and downloads each
- file; otherwise this downloads the file named "foo" (if any) from the
- server's current directory.
- mget /nlst *.txt NLST *.txt Gets a list of the files in the server's
- current directory whose names match the pattern *.txt, and then
- downloads each file from the list. Because we are using NLST, we send
- the filespec (*.txt) to the server and the server interprets any
- wildcards.
- mget /nlst foo/*.txt NLST foo/*.txt Gets a list of the files in the
- server's "foo" directory whose names match the pattern *.txt, and then
- downloads each file from the list (server interprets wildcards).
- mget /nlst /match:*.txt NLST Gets a list of all the files in the
- server's current directory and then downloads each one whose name
- matches the pattern *.txt (client interprets wildcards).
- mget /nlst /match:*.txt foo NLST foo Gets a list of all the files in
- the server's "foo" directory and then downloads each one whose name
- matches the pattern *.txt (client interprets wildcards).
- mget /mlsd MLSD Gets a list of all the files from the server's current
- directory and then downloads each one. The list might include size and
- timestamp information, in which case Kermit does not need to send SIZE
- and MDTM directives for each file (this is always true of MLSD).
- mget /mlsd foo MLSD foo Gets a list of all the files from the server's
- "foo" directory (where the string "foo" does not contain wildcards)
- and then downloads each one. If "foo" is a regular file and not a
- directory, this command is supposed to fail, but some servers have
- been observed that send the file.
- mget /mlsd *.txt MLSD Gets a list of all the files from the server's
- current directory and then downloads only the ones whose names match
- the pattern "*.txt". Because we are using MLSD and the MGET filespec
- is wild, we do not send the filespec to the server, but treat it as
- though it had been given in a /MATCH: switch and use it locally to
- match the names in the list.
- mget /mlsd foo/*.txt MLSD This one won't work because MLSD requires
- that the notions of server directory and filename-matching pattern be
- separated. However, the client, which can't be expected to know the
- server's file-system syntax, winds up sending a request that the
- server will (or should) reject.
- mget /mlsd /match:*.txt MLSD Gets a list of all the files from the
- server's current directory and then downloads only the ones whose
- names match the pattern "*.txt" (client interprets wildcards).
- mget /mlsd /match:*.txt foo MLSD foo If "foo" is a directory on the
- server, this gets a list of all the files from the server's "foo"
- directory and then downloads only the ones whose names match the
- pattern "*.txt" (client interprets wildcards). This leaves the server
- CD'd to the "foo" directory; there's no way the client can restore the
- server's original directory because MLSD doesn't give that
- information, and since the client can not be expected to know the
- server's file-system syntax, it would not be safe to guess. If "foo"
- is a regular file, MLSD fails.
- mget /mlsd foo bar MLSD This one is problematic. You're supposed to be
- able to give MGET a list a filespecs; in this case we name two
- directories. The client must change the server's directory to "foo" to
- get the list of files, and then the files themselves. But then it has
- no way to return to the server's previous directory in order to do the
- same for "bar", as explained in the previous example.
- mget /mlsd /match:* [abc] MLSD [abc] Including a /MATCH: switch forces
- [abc] to be sent to the server even though the client would normally
- think it was a wildcard and hold it for local interpretation. In this
- example, [abc] might be a VMS directory name.
- mget /mlsd /match:* t*.h MLSD t*.h Contrary to the MLSD specification,
- some MLSD-capable FTP servers do interpret wildcards. This form of the
- MGET command can be used to force a wildcard to be sent to the server
- for interpretation.
-
- When MLSD is used implicitly (that is, without an /MLSD switch given
- to force the use of MLSD) and an MGET command such as "mget foo/*.txt"
- fails, Kermit automatically falls back to NLST and tries again.

-4. FILE SCANNING
-
- A new feature called file scanning is used in various contexts to
- determine if a file is text or binary, and if it is text, what kind of
- text. The overhead of file scanning is surprisingly tolerable, usually
- about a quarter second per file. File scanning is now used instead of
- filename patterns unless you SET FILE SCAN OFF, which restores the
- previous behavior.
-
- The primary benefit of file scanning is in file transfer. For all
- practical purposes, now you can stop worrying about whether a file
- should be sent in binary or text mode, or about sending mixtures of
- text and binary files in a single operation, or configuring and
- fine-tuning your lists of binary-file and text-file name patterns: now
- it all just works.
-
- File scanning is done by the file sender, which determines the type of
- each file before it sends it and informs the receiver (Kermit or FTP
- server) of the type. File scanning is NOT done by the receiver,
- because it is the sender's responsibility to determine each file's
- type, send the file in the right mode, and inform the receiver of the
- mode. If both transfer partners are capable of this (or any other)
- form of automatic text/binary mode switching, then files can be sent
- in both directions with no worries about corruption due to
- inappropriate transfer mode. (As noted in [369]Section 3, FTP servers
- don't do this, so this discussion does not apply when using Kermit to
- download from an FTP server.)
-
- The rest of this section is mainly for the curious. If you don't read
- it and simply accept all defaults, every file you send should go in
- the appropriate mode automatically. As always, however, for
- character-set translation to work for 7- and 8-bit character-set
- files, the appropriate SET FILE CHARACTER-SET command(s) must have
- been executed to identify their encoding (Kermit's default file
- character-set is neutral ASCII except on platforms like HP-UX or
- DG/UX, where the default file character-set is known). And of course,
- receiving is another matter -- obviously the other Kermit must also
- send each file in the appropriate mode.
-
- Scanning is more reliable than filename patterns simply because
- filenames are not reliable indicators of the file's contents. Classic
- examples include ".doc" files, which are binary if Microsoft Word
- documents but text on most other platforms, and ".com" files, which
- are binary on DOS and Windows but text on VMS. Anyway, nobody knows
- the naming conventions (if any) of all the applications (and persons!)
- on your computer. Scanning, on the other hand, determines each file's
- type by inspecting its contents rather than just looking at its name.
-
- Also, file patterns -- even when they work as intended -- categorize
- each file only as text or binary, whereas file scanning can make finer
- distinctions:
-
- BINARY
- Binary data, not to be converted in any way. Examples include
- binary machine code (executable programs), graphics images
- (GIF, JPG, etc), compressed files (Z, GZ, etc), archives and
- packages (ZIP, TAR, RPM, etc), object files and libraries (OBJ,
- DLL, etc).
-
- 7-BIT TEXT
- Text encoded in a 7-bit character set such as ASCII or one of
- the ISO 646 national versions. Kermit has no way to tell which
- character is used, only that it's 7-bit text. Typical examples
- include program source code, README files, Perl or Kermit
- scripts, plain-text email, HTML, TeX, and various textual
- encodings of binary files: Hex, Base64, etc. When sending such
- files, the FILE DEFAULT 7BIT-CHARACTER-SET is used as the file
- character-set, and then the appropriate transfer character set
- is chosen from the associations list (ASSOCIATE, SHOW
- ASSOCIATIONS).
-
- 8-BIT TEXT
- Text encoded in an 8-bit character set such as Latin-1,
- Latin-2, Latin/Hebrew, Latin/Cyrillic, KOI8, HP-Roman8, JIS X
- 0208, Code Page 437, or Code Page 1252. Again, Kermit has no
- way of knowing which particular set is in use, only that it's
- 8-bit text. When sending such files, the FILE DEFAULT
- 8BIT-CHARACTER-SET is used as the file character-set, and then
- the appropriate transfer character set is chosen from the
- associations list.
-
- UCS2 TEXT
- Unicode in its basic form, 16 bits (2 octets) per character.
- When sending such files, UCS2 is the file character-set and the
- byte order is identified automatically; the appropriate
- transfer character set is chosen from the associations list.
- Normally this would be UTF8. UTF-16 is not supported yet;
- Kermit's Unicode translations are restricted to Plane 0, the
- Base Multilingual Plane (BMP).
-
- UTF8 TEXT
- Unicode in its 8-bit transformation format. When sending such
- files, UTF8 is the file character-set; the appropriate transfer
- character set is chosen from the associations list, normally
- UCS2 or UTF8.
-
- File scanning is available in UNIX C-Kermit, in K-95, and to a limited
- extent, in VMS C-Kermit (full scanning is problematic in VMS because
- even plain-text files might contain binary record-format information).
- The relevant commands are:
-
- SET TRANSFER MODE { AUTOMATIC, MANUAL }
- Tells whether the file-transfer mode (text or binary) should be
- set by automatic or "manual" means. AUTOMATIC is the default,
- which allows any of the automatic methods that are enabled to
- do their jobs: FILE SCAN, FILE PATTERNS, peer recognition, etc.
- MANUAL lets you control the transfer mode with the SET FILE
- TYPE commands. As always, /TEXT and /BINARY switches on your
- file-transfer commands override all other methods; if you give
- one of these switches, scanning is not done. SHOW TRANSFER
- displays the current TRANSFER MODE setting.
-
- SET FILE SCAN { ON [ number ], OFF }
- Turns this feature on and off. It's ON by default. When OFF,
- the previous rules apply (SET FILE PATTERNS, etc). When ON is
- given, you can also specify a number of bytes to be scanned.
- The default is 49152 (= 48K). If a negative number is given,
- the entire file is scanned, no matter how big, for maximum
- certainty (for example, a PostScript file that appears to be
- plain text might include an embedded graphic past the normal
- scanning limit). SHOW FILE displays the current FILE SCAN
- setting.
-
- SET FILE DEFAULT 7BIT-CHARACTER-SET name
- Tells the 7-bit character-set to use if scanning identifies a
- 7-bit text file, e.g. GERMAN. SHOW FILE displays the current
- SET FILE DEFAULT settings. So does SHOW CHARACTER-SETS.
-
- SET FILE DEFAULT 8BIT-CHARACTER-SET name
- Tells the 8-bit character-set to use if scanning identifies an
- 8-bit text file, e.g. LATIN1. SHOW FILE and SHOW CHARACTER-SET
- display this.
-
- ASSOCIATE FILE-CHARACTER-SET fcs tcs
- When sending files and a file character-set (fcs) is identified
- by scanning, this tells C-Kermit which transfer character-set
- (tcs) to translate it to. It also allows C-Kermit to set the
- appropriate transfer character-set automatically whenever you
- give a SET FILE CHARACTER-SET command.
-
- ASSOCIATE TRANSFER-CHARACTER-SET tcs fcs
- When receivinging files and a file arrives whose transfer
- character-set (tcs) is announced by the sender, this command
- tells C-Kermit which file character-set (fcs) to translate it
- to. It also allows C-Kermit to set the appropriate file
- character-set whenever you give a SET TRANSFER CHARACTER-SET
- command.
-
- SET FILE CHARACTER-SET name
- When given for a 7-bit set, also sets FILE DEFAULT
- 7BIT-CHARACTER-SET to the same set. When given for an 8-bit
- set, also sets FILE DEFAULT 8BIT-CHARACTER-SET to the same set.
- If an ASSOCIATE FILE-CHARACTER-SET command has been given for
- this set, also sets the corresponding transfer character-set.
-
- DIRECTORY /XFERMODE [ filespec ]
- Performs a file scan of the given files, listing the result for
- each file. If FILE SCAN is OFF but PATTERNS are ON, the result
- shown according to the current FILE TEXT-PATTERNS and
- BINARY-PATTERNS, and are restricted to (B) and (T). When FILE
- SCAN is ON, the results are:
-
- (B) Binary
- (T)(7BIT) Text: 7-bit
- (T)(8BIT) Text: 8-bit
- (T)(UTF8) Text: Unicode UTF8
- (T)(UCS2BE) Text: Unicode UCS2 Big Endian
- (T)(UCS2LE) Text: Unicode UCS2 Little Endian
-
- So you can use DIR /XFER to get a preview of how each file in a
- selected group will be transferred. Everything to the right of
- the (B) or (T) is new. If FILE SCAN is OFF, you only get the
- (B) or (T) as before.
-
- Note: Big and Little Endian refer to the ordering of bytes
- within a computer word. Big Endian architecture is standard and
- is used on most non-PC computers. Little Endian architecture is
- used on PCs.
-
- To illustrate file-transfer with scanning, suppose you have a
- directory containing a mixture of text and binary files, and each text
- file can be 7-bit German ISO 646, 8-bit Latin-1, or Unicode in any of
- the following forms: UCS2 Little Endian, UCS2 Big Endian, or UTF8
- ([370]UTF-16 is not supported yet). Assuming all the built-in defaults
- are in effect, the following three commands do the job:
-
- set file char german ; This sets the default for 7-bit text files
- set file char latin1 ; This sets the default for 8-bit text files
- send *
-
- Each file is sent in the appropriate mode (text or binary), with text
- files converted to the appropriate transfer character-set and labeled
- so the receiver can convert them according to its own local
- conventions.
-
- By the way, what if you want to inhibit character-set translation but
- still allow automatic text/binary mode switching? Previously, you
- could simply SET TRANSFER CHARACTER-SET TRANSPARENT. But now with file
- scanning, the file and transfer character-sets are set automatically
- per file. A new command was added for this purpose:
-
- SET TRANSFER TRANSLATION { ON, OFF }
- Enables and disables file-transfer character-set translation.
- It is enabled by default.
-
- When TRANSFER TRANSLATION is OFF but FILE SCAN is ON, files are still
- scanned to see if they are text or binary, but no character-set
- translation is done when they text: only the normal record-format
- conversion.
-
- Like all SET commands, SET TRANSFER TRANSLATION is global and
- persistent. You can also force a particular file-transfer command
- (SEND, MSEND, GET, RECEIVE, TRANSMIT, etc) to not translate without
- affecting the global translation settings by including the new
- /TRANSPARENT switch, e.g.
-
- send /transparent oofa.txt
-
- As of C-Kermit 8.0.206, SET TRANSFER CHARACTER-SET TRANSPARENT implies
- SET TRANSFER TRANSLATION OFF.
-
- File scanning is also used in the TYPE command. The source file type
- and character set are determined as above, and then the file is
- automatically converted to your display character-set, line by line.
- In Kermit 95, the display character-set is Unicode, perhaps converted
- to your current console code page; in other versions of C-Kermit, it
- is your current file character-set. Thus if you have the following set
- appriately:
-
- SET FILE CHARACTER-SET (necessary in Unix but not K95)
- SET FILE DEFAULT 7BIT CHARACTER-SET
- SET FILE DEFAULT 8BIT CHARACTER-SET
-
- then you should be able to TYPE any text file and see something
- reasonable. For example, in Unix, if your DEFAULT 7BIT-CHARACTER-SET
- is ITALIAN and your DEFAULT 8BIT-CHARACTER-SET is LATIN1, and your
- FILE CHARACTER-SET is LATIN1, you can TYPE an Italian ISO 646 file, a
- Latin-1 file, or any kind of Unicode file, and have it translated
- automatically to Latin-1 for your display.
-
- In the GUI version of Kermit 95, you can see mixtures of many
- different scripts if the file is UTF8 or UCS2: Roman, Cyrillic,
- Hebrew, Greek, Armenian, Georgian, etc, all on the same screen at
- once.
-
- File scanning also adds a new criterion for file selection, i.e. to
- select only text (or binary) files. Several commands now include a new
- switch, /TYPE:{BINARY,TEXT,ALL}. BINARY means select only binary
- regular files (not directories). TEXT means select only text files.
- ALL means don't scan; select all files. Examples:
-
- SEND /TYPE:BINARY *.*
- Sends only binary files, skipping over text files.
-
- NOTE: File scanning is NOT done when using external protocols (because
- the external protocol programs, such as sz, are processing each file,
- not Kermit).
-
- DIRECTORY /TYPE:TEXT
- Lists only text files but not binary files.
-
- DELETE /TYPE:BINARY foo.*
- Deletes all foo.* files that are regular binary files but does
- not delete any text files.
-
- CHMOD /TYPE:BINARY 775 *
- (UNIX) Changes the permissions of all binary files to 775.
-
- When FILE SCAN is OFF and FILE PATTERNS are ON, behavior is as before
- with PATTERNS ON, but with some improvements:
-
- * Pathnames are now stripped prior to pattern matching.
- * Backup suffixes (like .~3~) are stripped prior to pattern
- matching.

-5. FILE AND DIRECTORY NAMES CONTAINING SPACES
-
- Prior to the introduction of the graphical user interface (GUI), it
- was inconceivable that file or directory names could contain spaces,
- because space is a field delimiter in all command languages. GUIs,
- however, use dialog boxes for filenames, so there is never any
- question of distinguishing a filename from adjacent fields -- because
- there are no adjacent fields -- and therefore it has become quite
- common on computers that have GUIs to have file and directory names
- composed of multiple words. Of course this poses problems for command
- shells and other text-oriented programs.
-
- Most command shells address these problems by allowing such names to
- be enclosed in doublequotes, e.g.:
-
- cd "c:\Program Files"
-
- C-Kermit previously used braces for this:
-
- cd {c:\Program Files}
-
- which was not what most people expected. And even when braces were
- used, Kermit had difficulties with completion, file menus, and so
- forth, within braced fields.
-
- C-Kermit 8.0 allows either doublequotes or braces to be used for
- grouping:
-
- send "this file"
- send {this file}
- rename "this file" "that file"
- rename {this file} "that file"
- rename "this file" {that file}
- cd {Program Files}
- cd "Program Files"
-
- Note that the doublequotes or brackets must enclose the whole file or
- directory specification:
-
- "c:\My Directory"
-
- not:
-
- c:\"My Directory"
-
- In C-Kermit 8.0, you can also use completion on these filenames, in
- which case Kermit supplies the quotes (or braces) automatically.
- Example (in which the current directory contains only one file whose
- name starts with "th" and its full name is "this file" (without the
- quotes, but with the space)):
-
- cat th<Tab>
-
- Kermit repaints the filename field like this:
-
- cat "this file"
-
- That is, it backspaces over the original "th" and then writes the
- filename in doublequotes.
-
- If completion is only partial, Kermit still supplies the quotes, but
- in this case also beeps. To continue the filename, you must first
- backspace over the closing quote. The closing quote is supplied in
- this case to make sure that you can see the spaces, especially if they
- are trailing. For example, if the current directory contains two files
- whose names start with "th", and their fill names are "this file" and
- "this other file":
-
- cat th<Tab>
-
- Kermit prints:
-
- cat "this "<Beep>
-
- If it didn't print the closing quote, you would probably wonder why it
- was beeping.
-
- Also, if you begin a filename field with a doublequote or opening
- brace, now you can use completion or get ?-help; this was never
- possible before.

-6. OTHER COMMAND PARSING IMPROVEMENTS
-
- 6.1. Grouping Macro Arguments
-
- Doublequotes now can be used in macro invocations to group arguments
- containing spaces, where previously only braces could be used:
-
- define xx show args
- xx one "this is two" three
-
- Result:
-
- Macro arguments at level 0 (\v(argc) = 4):
- \%0 = xx
- \%1 = one
- \%2 = this is two
- \%3 = three
-
- Also, you can now quote braces and quotes in macro args (this didn't
- work before). Examples:
-
- xx "{" ; The argument is a single left brace
- xx {"} ; The argument is a doublequote character
-
- In case this new behavior interferes with your scripts, you can
- restore the previous behavior with:
-
- SET COMMAND DOUBLEQUOTING OFF
-
- 6.2. Directory and File Name Completion
-
- C-Kermit 8.0 also includes better completion for directory names, e.g.
- in the CD command. If the name typed so far uniquely matches a
- directory name, it is completed (as before), but now if the directory
- contains any subdirectories, completion is partial (allowing you to
- supply additional path segments without backspacing); otherwise it is
- complete.
-
- Completion has also been improved for file and directory names that
- contain not only spaces (as described above) but also "metacharacters"
- such as asterisk (*) and tilde (~): now the field is repainted if
- necessary. For example, if the current directory contains only one
- file whose name contains "blah", then in:
-
- type *blah<Tab>
-
- "*blah" is replaced by the filename. In earlier releases, the part
- typed so far was left on the command line (and in the history buffer),
- so even when the original command worked, the recalled version would
- not. Similarly for ~ (the nearly-universal Unix notation for
- username):
-
- type ~olga/x<Tab>
-
- is repainted as (e.g.):
-
- type /users/home/olga/x(Beep)
-
- Speaking of command history, the new SHOW HISTORY command shows your
- command history and recall buffer. SAVE COMMAND HISTORY saves it into
- a file of your choice.
-
- 6.3. Passing Arguments to Command Files
-
- The method for passing arguments to command files has been improved.
- Prior to C-Kermit 7.0 there was no provision for doing this. In
- C-Kermit 7.0, the TAKE command was changed to allow arguments to be
- given after the filename:
-
- take commandfile arg1 arg2 ...
-
- This was accomplished by replacing the current \%1, \%2, etc, with the
- given arguments, since a new set of macro argument variables is
- created only when a macro is executed, not a command file. It is much
- more intuitive, however, if arguments to command files worked like
- those to macros: the command file sees the arguments as its own \%1,
- \%2, etc, but the caller's variables are not disturbed. C-Kermit 8.0
- accomplishes this by automatically creating an intermediate temporary
- macro to start the command file (if any arguments were given), thus
- creating a new level of arguments as expected.
-
- 6.4. More-Prompting
-
- The familiar --more?-- prompt that appears at the end of each
- screenful of command-response output now accepts a new answer: G (Go)
- meaning "show all the rest without pausing and asking me any more
- questions". P (Proceed) is a synonym for G.
-
- 6.5. Commas in Macro Definitions
-
- As noted in the [379]C-Kermit manual, comma is used to separate
- commands in a macro definition. Even when the macro is defined on
- multiple lines using curly-brace block-structure notation without
- commas, the definition is still stored internally as a comma-separated
- list of commands. Therefore special tricks are needed to include a
- comma in a command. The classic example is:
-
- define foo {
- (some command)
- if fail echo Sorry, blah failed...
- }
-
- This would result in Kermit trying to execute a "blah" command. This
- could always be handled by enclosing the text in braces:
-
- define foo {
- (some command)
- if fail echo {Sorry, blah failed...}
- }
-
- but doublequotes (more intuitive) should have worked too. Now they do:
-
- define foo {
- (some command)
- if fail echo "Sorry, blah failed..."
- }
-
- 6.6. Arrow Keys
-
- As of version 8.0.201, C-Kermit on most platforms lets you access the
- command history buffer with arrow keys, just as you always could with
- control characters. The restrictions are:
-
- 1. Only Up and Down arrow keys are accepted.
- 2. Only 7-bit ANSI arrow-key sequences are understood (ESC followed
- by [ or uppercase letter O, followed by uppercase letter A or (up)
- B (down).
-
- This change was made to facilitate command recall in Linux-based PDAs
- that don't have a Control key, or at least not one that's easily (or
- always) accessible, such as the Sharp Zaurus SL5500.

-7. NEW COMMANDS AND SWITCHES
-
- See [384]Section 4 for more about file scanning and the /TYPE: switch.
-
- ASK[Q] [ /TIMEOUT:number /QUIET /DEFAULT:text ] variable [ prompt ]
- The new optional /TIMEOUT: switch for ASK and ASKQ causes the
- command to time out and and fail if no response is given within
- the specified number of seconds, 1 or greater (0 or less means
- no timeout, wait forever). This works just like SET ASK-TIMER,
- except its effect is local to the ASK command with which it is
- given and it does not disturb the global ask timer setting. The
- new /QUIET switch tells Kermit not to print an error message if
- the ASK or ASKQ command times out waiting for a response.
-
- Version 8.0.211 adds the /DEFAULT:text switch for ASK-Class
- commands (ASK, ASKQ, and GETOK). This lets you supply a default
- answer in case the user supplies an empty answer or the
- /TIMEOUT: switch was included and the time limit expired
- without an answer. In both these cases, the command succeeds.
-
- CAT filename
- Equivalent to TYPE /NOPAGE.
-
- CDUP
- Changes Kermit's local working directory to the parent of the
- current one. Equivalent to "cd .." in UNIX or Windows, "cd [-]"
- in VMS, "cd ^" in AOS/VS, etc; in other words, it's a
- platform-independent way of moving one level up in a directory
- tree.
-
- CHMOD [ switches ] permission files
- UNIX only. Sets file permissions for one or more files or
- directories. The permission must be given as an octal number,
- e.g. 664, 755. Switches: /DIRECTORIES, /FILES, /NOLIST, /PAGE,
- /DOTFILES, /LIST, /NOPAGE, /RECURSIVE, /TYPE:{TEXT,BINARY,ALL},
- /SIMULATE. The /TYPE: switch allows selection of only text or
- binary files. For example, if you have a mixture of source
- files and executables, you can use "chmod /files /type:text
- 664" to give owner/group read/write and world read permission
- to the text files, and "chmod /files /type:binary 775" to give
- the same plus execute permission to the executables. Use
- /SIMULATE to see which files would be affected, without
- actually changing their permissions.
-
- CLEAR KEYBOARD-BUFFER
- Flushes any as-yet unread characters from the keyboard input
- buffer. Useful for flushing typeahead in scripts.
-
- CONTINUE
- When given at an interactive command prompt that was reached by
- issuing a PROMPT command (described in this section) from a
- script, this command returns to the script, continuing its
- execution at the command after the PROMPT command. In this
- context, CONTINUE is simply a more-intuitive synonym for END.
-
- COPY, RENAME, and TRANSLATE
- These commands now work on file groups if the target filename
- is a directory, e.g. "copy oofa.* ..", "rename * ~olga/tmp/"
-
- COPY /APPEND source destination
- The source file specification can now include wildcards, in
- which case all of the source files that match will go into the
- destination file in alphabetical order by name.
-
- DELETE /ASK
- Asks permission to delete each file before deleting it. In
- C-Kermit 7.0, the answers were "yes" (or "ok") and "no".
- C-Kermit 8.0 adds "go" (meaning, delete all the rest without
- asking) and "quit" (cancel the DELETE command and return to the
- prompt).
-
- DELETE /DIRECTORIES
- Deletes not only files but also directories.
-
- DELETE /RECURSIVE
- Deletes all files that match the given file specification in
- the current (or given) directory and all directories beneath
- it.
-
- DELETE /SUMMARY
- Prints only the number of files deleted and total size freed,
- without listing each file.
-
- DELETE /TREE
- Shorthand for DELETE /RECURSIVE /DIRECTORIES /DOTFILES/.
- Equivalent to Windows DELTREE or Unix "rm -Rf". If no file
- specification is given, the contents of the current directory,
- plus all of its subdirectories and their contents, are deleted.
-
- DELETE /TYPE:BINARY
- Delete only regular binary files (requires FILE SCAN ON).
-
- DELETE /TYPE:TEXT
- Delete only regular text files (requires FILE SCAN ON).
-
- DIRECTORY [ switches ] [ filespec [ filespec [ filespec ... ] ] ]
- The DIRECTORY command now accepts more than one file
- specification; e.g. "directory moon.txt sun.doc stars.*".
-
- DIRECTORY /NORECURSIVE xxx
- If xxx is a directory name, forces listing of the directory
- itself rather than its contents.
-
- DIRECTORY /FOLLOWLINKS xxx
- (UNIX only) Tells the DIRECTORY command to follow symbolic
- links. This not the default because it can cause endless loops.
-
- DIRECTORY /NOFOLLOWLINKS xxx
- (UNIX only) Tells the DIRECTORY command not to follow symbolic
- links, but rather, merely to list them. This is the default.
-
- DIRECTORY /OUTPUT:filename
- Sends the results of the DIRECTORY command to the given file.
-
- DIRECTORY /SUMMARY
- Prints only the number of directories and files and the total
- size, without listing each file.
-
- DIRECTORY /TYPE:{TEXT,BINARY}
- Shows only files of the selected type, based on file scan.
-
- DIRECTORY /XFERMODE
- Now shows results of file scan (see [385]Section 4).
-
- FOPEN [ switches ] channel filename
-
- As of version 8.0.211, FOPEN allows /dev/tty as a filename in
- Unix-based operating systems.
-
- FREAD /TRIM
- (8.0.211) Trims any trailing blanks or tabs from the item (such
- as a line of text) that it has read.
-
- FREAD /UNTABIFY
- (8.0.211) Converts Horizontal Tab characters to the appropriate
- number of spaces, based on VT100-like tab stops
- (1,9,17,25,...).
-
- GREP [ switches ] pattern files
- Similar to Unix grep command: displays file lines that match
- the given [386]pattern. Switches:
-
- /COUNT[:variable]
- Don't show the matching lines, just tell how many lines
- match. If a variable name is specified, the count is
- stored in the given variable.
-
- /DOTFILES
- Include files whose names begin with dot.
-
- /LINENUMBERS
- Show line numbers of matching lines.
-
- /NAMEONLY
- only list the names of files that contain matching lines,
- but not the lines themselves.
-
- /NOBACKUP
- Skip backup files.
-
- /NOCASE
- Ignore alphabetic case while pattern matching.
-
- /NODOTFILES
- skip files whose names start with dot (period).
-
- /NOLIST
- Suppress output but set SUCCESS or FAILURE according to
- search result.
-
- /NOMATCH
- Look for lines that do not match the pattern.
-
- /NOPAGE
- Don't pause between screens of output.
-
- /OUTPUT:filename
- Write results into the given file.
-
- /PAGE
- Pause between screens of output.
-
- /RECURSIVE
- Search files in subdirectories too.
-
- /TYPE:{TEXT,BINARY}
- Search only files of the specified type.
-
- Synonyms: FIND, SEARCH.
-
- GETOK /TIMEOUT:n /QUIET /DEFAULT:text
- The new /QUIET switch instructs GETOK, when given a timeout,
- not to print an error message if it times out. As of 8.0.211, a
- default answer can be supplied (see ASK).
-
- HEAD [ switches ] filename
- Equivalent to TYPE /HEAD [ other-switches ] filename.
-
- HELP DATE
- Explains date-time formats, including timezone notation and
- delta times.
-
- HELP FIREWALLS
- Explains the firewall negotiation capabilities of your version
- of Kermit.
-
- KCD [ symbolic-directory-name ]
- Changes Kermit's working directory to the named symbolic
- directory, such as such as exedir, inidir, startup, download,
- or and home. Type "kcd ?" for a list of symbolic directory
- names known to your copy of Kermit, or give the new ORIENTATION
- command for a more detailed explanation. If you give a KCD
- command without a directory name, Kermit returns to its "home"
- directory, which is determined in some way that depends on the
- underlying operating system, but which you can redefine with
- the (new) SET CD HOME command. Your home directory is shown by
- SHOW CD and it's also the value of the \v(home) variable.
-
- LICENSE
- Displays the C-Kermit license.
-
- L-commands
- When Kermit has a connection to a Kermit or FTP server, file
- managment commands such as CD, DIRECTORY, and DELETE might be
- intended for the local computer or the remote server. C-Kermit
- 8.0.200 and earlier always executes these commands on the local
- computer. If you want them executed by the remote server, you
- have to prefix them with REMOTE (e.g. REMOTE CD) or use special
- R-command aliases (e.g. RCD = REMOTE CD, RDIR = REMOTE DIR,
- etc). But this feels unnatural to FTP users, who expect
- unprefixed file management commands to be executed by the
- remote server, rather than locally. C-Kermit 8.0.201 adds
- automatic locus switching to present an FTP-like interface for
- FTP connections and the normal Kermit interface for Kermit
- connections, and a SET LOCUS command (described below) to
- control whether or how this is done. For when LOCUS is REMOTE,
- a new set of commands was added for local management: LCD
- (Local CD), LDIR (Local DIR), etc. These are described below
- under SET LOCUS.
-
- MORE filename
- Equivalent to TYPE /PAGE.
-
- ORIENTATION
- Displays symbolic directory names and the corresponding
- variable names and values. The symbolic names, such as exedir,
- inidir, startup, download, and home, can be used as arguments
- to the new KCD command.
-
- PROMPT [ text ]
- For use in a macro or command file: enters interactive command
- mode within the current context ([387]Section 8.1). If the
- optional text is included, the prompt is set to it. The text
- can include variables, functions, etc, as in the SET PROMPT
- command. They are evaluated each time the prompt is printed.
- Unlike the SET PROMPT command, the text argument applies only
- to the current command level. Thus you can have different
- prompts at different levels.
-
- REMOTE SET MATCH { DOTIFILE, FIFO } { ON, OFF }
- Allows the client to tell the server whether wildcards sent to
- the server should match dot files (files whose names begin with
- period) or FIFOs (named pipes). See SET MATCH.
-
- SET ATTRIBUTE RECORD-FORMAT { ON, OFF }
- Allows control of the Kermit's Record-Format attribute. Set
- this to OFF in case incoming file are refused due to unknown or
- invalid record formats if you want to accept the file anyway
- (and, perhaps, postprocess it to fix its record format).
-
- SET CD HOME [ directory ]
- Specifies the target directory for the CD and KCD commands,
- when they are given without an argument, and also sets the
- value of the \v(home) variable.
-
- SET EXIT HANGUP { OFF, ON }
- Normally ON, meaning that when Kermit exits, it also explicitly
- hangs up the current SET LINE / SET PORT serial port according
- to the current SET MODEM TYPE and SET MODEM HANGUP METHOD, and
- closes the port device if it was opened by Kermit in the first
- place (as opposed to inherited). SET EXIT HANGUP OFF tells
- Kermit not to do this. This can't prevent the operating system
- from closing the device when Kermit exits (and it's a "last
- close") but if the port or modem have been conditioned to
- somehow ignore the close and keep the connection open, at least
- Kermit itself won't do anything explicit to hang it up or close
- it.
-
- SET FILE EOF { CTRL-Z, LENGTH }
- Specifies the end-of-file detection method to be used by
- C-Kermit when sending and receiving text files, and in the TYPE
- and similar text-file oriented commands. The normal and default
- method is LENGTH. You can specify CTRL-Z when handling CP/M or
- MS-DOS format text files, in which a Ctrl-Z (ASCII 26)
- character within the file marks the end of the file.
-
- SET FILE LISTSIZE number
- Allocates space for the given number of filenames to be filled
- in by the wildcard expander. The current number is shown by
- SHOW FILE. If you give a command that includes a filename
- containing a wildcard (such as "*") that matches more files
- that Kermit's list has room for, you can adjust the list size
- with this command.
-
- SET FILE STRINGSPACE number
- Allocates space for the given amount of filename strings for
- use by the wildcard expander. The current number is shown by
- SHOW FILE. The number is the total number of bytes of all the
- file specifications that match the given wildcard.
-
- If you need to process a bigger list of files than your computer
- has memory for, you might be able use an external file list. The
- Kermit SEND and the FTP PUT and GET commands accept a /LISTFILE:
- switch, which gives the name of a file that contains the list of
- files to be transferred. Example for UNIX:
-
- !find . -print | grep / > /tmp/names
- ftp put /update /recursive /listfile:/tmp/names
-
- SET LOCUS { AUTO, LOCAL, REMOTE }
- Added in C-Kermit 8.0.201. Sets the locus for unprefixed file
- management commands such as CD, DIRECTORY, MKDIR, etc. When
- LOCUS is LOCAL these commands act locally and a REMOTE (or R)
- prefix (e.g. REMOTE CD, RCD, RDIR) is required to send file
- management commands to a remote server. When LOCUS is REMOTE,
- an L prefix is required to issue local file management commands
- (e.g. LCD, LDIR). The word LOCAL can't be used as a prefix
- since it is already used for declaring local variables. LOCUS
- applies to all types of connections, and thus is orthogonal to
- SET GET-PUT-REMOTE, which selects between Kermit and FTP for
- remote file-transfer and management commands. The default LOCUS
- is AUTO, which means we switch to REMOTE whenever an FTP
- connection is made, and to LOCAL whenever a non-FTP connection
- is made, and switch back accordingly whenever a connnection is
- closed. So by default, Kermit behaves in its traditional manner
- unless you make an FTP connection, in which case it acts like a
- regular FTP client (but better :-) LOCUS applies to the
- following commands:
-
- Unprefixed Remote Local Description
- CD (CWD) RCD LCD Change (Working) Directory
- CDUP RCDUP LCDUP CD Up
- PWD RPWD LPWD Print Working Directory
- DIRECTORY RDIR LDIR Request a directory listinga
- DELETE RDEL LDEL Delete (a) file(s)
- RENEME RREN LREN Rename a file
- MKDIR RMKDIR LMKDIR Create a directory
- RMDIR RRMDIR LRMDIR Remove a directory
-
- SET MATCH { DOTIFILE, FIFO } { ON, OFF }
- Whether C-Kermit filename patterns (wildcards) should match
- filenames that start with dot (period), or (Unix only) FIFOs
- (named pipes). The defaults are to skip dotfiles in Unix but
- match them elsewhere, and to skip FIFOs. Applies to both
- interactive use and to server mode, when the server receives
- wildcards, e.g. in a GET command. Also see REMOTE SET MATCH.
-
- SET OPTIONS DIRECTORY /DOTFILES
- Now works for server listings too (UNIX only). Give this
- command prior to having Kermit enter server mode, and then it
- will show files whose names begin with dot (period) when sent a
- REMOTE DIRECTORY command.
-
- SET QUIET ON
- (as well as the -q command-line option) Now applies also to:
-
- + SET HOST connection progress messages.
- + "Press the X or E key to cancel" file-transfer message.
- + REMOTE CD response.
- + REMOTE LOGIN response.
-
- SET RECEIVE PERMISSIONS { ON, OFF }
- Tells C-Kermit whether to set the permissions of incoming files
- (received with Kermit protocol) from the permissions supplied
- in the file's Attribute packet (if any). Normally ON. Also see
- SET SEND PERMISSIONS.
-
- SET ROOT directory
- Like UNIX chroot, without requiring privilege. Sets the root
- for file access, does not allow reference to or creation of
- files outside the root, and can't be undone.
-
- SET SEND PERMISSIONS { ON, OFF }
- Tells C-Kermit whether to include file permissions in the
- attributes it includes with each file when sending with Kermit
- protocol. Also see SET RECEIVE PERMISSIONS.
-
- SET TCP { HTTP-PROXY, SOCKS-SERVER } /USER:name /PASSWORD:text
- These commands now allow specification of username and
- password.
-
- SET TERMINAL . . .
- (See [388]Section 12.)
-
- SET TRANSFER MESSAGE [ text ]
- Sets an initial text message to be displayed in the
- file-transfer display. The transfer message is automatically
- deleted once used, so must be set each time a message a
- desired. Any variables in the message are evaluated at the time
- the SET command is given. If the optional text is omitted, any
- transfer message that is currently set is removed. Synonym: SET
- XFER MSG. SHOW TRANSFER displays it if it has been set but not
- yet used.
-
- SHOW COMMUNICATIONS
- In C-Kermit 8.0, SHOW COMMUNICATIONS, when given in remote mode
- (i.e. before any connection has been established), tells the
- typical dialout device name for the particular platform on
- which it's running (e.g. TXA0: for VMS, or /dev/cua0p0 for
- HP-UX). On Unix platforms, it also tells the name of the
- lockfile directory. This way, you have an idea of what the SET
- LINE device name should look like, and if the SET LINE command
- fails, you know the name of the directory or device that is
- protected against you.
-
- SHOW VARIABLES [ name [ name [ ... ] ] ]
- In C-Kermit 8.0.201 you can request values of a list of
- built-in (\v(xxx)) variables. Each name is a pattern, as
- before, but now it a free pattern rather than an anchored one
- (explained in [389]Section 8.12) so now "show var date time"
- shows the values of all variables whose names include the
- strings "date" or "time".
-
- TAIL [ switches ] filename
- Equivalent to TYPE /TAIL [ other-switches ] filename.
-
- TRANSMIT /NOECHO [ other switches ] filename
- The /NOECHO switch is equivalent to giving the command SET
- TRANSMIT ECHO OFF prior to the TRANSMIT command, except the
- switch affects only the command with which it was given and
- does not affect the prevailing global setting.
-
- TRANSMIT /NOWAIT [ other switches ] filename
- The /NOWAIT switch is equivalent to giving the command SET
- TRANSMIT PROMPT 0 prior to the TRANSMIT command, except the
- switch affects only the command with which it was given and
- does not affect the prevailing global setting.
-
- TRANSMIT /NOWAIT /NOECHO /BINARY [ other switches ] filename
- When the TRANSMIT command is given with the /NOWAIT, /NOECHO,
- and /BINARY switches, this activates a special "blast the whole
- file out the communications connection all at once" mode that
- Kermit didn't have prior to version 8.0. There has been
- increasing demand for this type of transmission with the advent
- of devices that expect image (e.g. .JPG) or sound (e.g. .MP3)
- files as raw input. The obvious question is: how does the
- receiving device know when it has the whole file? This depends
- on the device, of course; usually after a certain amount of
- time elapses with nothing arriving, or else when Kermit hangs
- up or closes the connection.
-
- TYPE /CHARACTER-SET:name
- Allows you to specify the character set in which the file to be
- typed is encoded.
-
- TYPE /NUMBER
- Adds line numbers.
-
- TYPE /OUTPUT:filename
- Sends the results of the TYPE command to the given file.
-
- TYPE /TRANSLATE-TO:name
- Used in conjunction with TYPE /CHARACTER-SET:xxx; allows you to
- specify the character set in which the file is to be displayed.
-
- TYPE /TRANSPARENT
- Used to disable character-set translation in the TYPE command,
- which otherwise can take place automatically based on file
- scanning, even when /CHARACTER-SET and /TRANSLATE-TO switches
- are not given.
-
- VOID text
- Parses the text, evaluating any backslash items in it (such as
- function calls) but doesn't do anything further, except
- possibly printing error messages. Useful for invoking functions
- that have side effects without using or printing their direct
- results, e.g. "void \fsplit(\%a,&a)".
-
- Symbolic Links in UNIX
-
- The UNIX versions of C-Kermit have had /FOLLOWLINKS and /NOFOLLOWLINKS
- switches added to several commands to control the treatment of
- symbolic links. Different commands deal differently with symbolic
- links:
-
- Kermit SEND, FTP MPUT
- /NOFOLLOWLINKS is the default, which means symbolic links are
- skipped entirely. The alternative, /FOLLOWLINKS, should be used
- with caution, since an innocent link might point to a whole
- file system, or it might cause a loop. There is no way in
- Kermit or FTP protocol to send the link itself. We either skip
- them or follow them; we can't duplicate them.
-
- DIRECTORY
- /NOFOLLOWLINKS is the default, which means the DIRECTORY
- command lists symbolic links in a way that shows they are
- links, but it does not follow them. The alternative,
- /FOLLOWLINKS, follows links and gives information about the
- linked-to directories and files.
-
- DELETE, RMDIR
- The DELETE command does not have link-specific switches. DELETE
- never follows links. If you tell Kermit to delete a symbolic
- link, it deletes the link itself, not the linked-to file. Ditto
- for RMDIR.
-
- COPY
- The COPY command behaves just like the UNIX cp command; it
- always follows links.
-
- RENAME
- The RENAME command behaves just like the UNIX mv command; it
- operates on links directly rather than following.

-8. OTHER SCRIPTING IMPROVEMENTS
-
- 8.1. Performance and Debugging
-
- A command cache for frequently used commands plus some related
- optimizations increases the speed of compute-bound scripts by anywhere
- from 50% to 1000%.
-
- The new PROMPT command can be used to set breakpoints for debugging
- scripts. If executed in a command file or macro, it gives you an
- interactive command prompt in the current context of the script, with
- all its variables, arguments, command stack, etc, available for
- examination or change, and the ability to resume the script at any
- point (END resumes it, Ctrl-C or STOP cancels it and returns to top
- level).
-
- The new Ctrl-C trapping feature ([394]Section 8.14) lets you intercept
- interruption of scripts. This can be used in combination with the
- PROMPT command to debug scripts. Example:
-

-
- Adding this ON_CTRL definition to your script lets you interrupt it at
- any point and get prompt that is issued at the current command level,
- so you can query local variables, etc.

- 8.2. Using Macros as Numeric Variables
-
- A macro is a way to assign a value to a name, and then use the name to
- refer to the value. Macros are used in two ways in Kermit: as
- "subroutines" or functions composed of Kermit commands, which are
- executed, or as variables to hold arbitrary values -- text, numbers,
- filenames, etc.
-
- When a macro is to be executed, its name is given as if it were a
- C-Kermit command, optionally preceded by the word "do". When a macro
- is used as a variable, it must be "escaped" with \m(xxx) (or
- equivalent function, e.g. \s(xxx), \:(xxx), \fdefinition(xxx)), where
- xxx is the macro name, for example:
-
- define filename /usr/olga/oofa.txt
- send \m(filename)
-
- Of course variables can also hold numbers:
-
- define size 17
- declare \&a[\m(size)]
- ...
- define index 3
- if ( == \m(index) 3 ) echo The third value is: \&a[\m(index)]
- evaluate index (\m(index) * 4)
- if ( > \m(index) \m(size) ) echo Out of range!
-
- But these are contexts in which only numbers are valid. C-Kermit 8.0
- has been changed to treat non-escaped non-numeric items in strictly
- numeric contexts as macro names. So it is now possible (but not
- required) to omit the \m(...) notation and just use the macro name in
- these contexts:
-
- define size 17
- declare \&a[size]
- ...
- define index 3
- if ( == index 3 ) echo The third value is: \&a[index]
- evaluate index (index * 4)
- if ( > index size ) echo Out of range!
-
- This is especially nice for loops that deal with arrays. Here, for
- example, is a loop that reverses the order of the elements in an
- array. Whereas formerly it was necessary to write:
-
- .\%n ::= \fdim(&a)
- for \%i 1 \%n/2 1 {
- .tmp := \&a[\%n-\%i+1]
- .\&a[\%n-\%i+1] := \&a[\%i]
- .\&a[\%i] := \m(tmp)
- }
-
- Recoding this to use macro names "i" and "n" instead of the backslash
- variables \%i and \%n, we have:
-
- .n ::= \fdim(&a)
- for i 1 n/2 1 {
- .tmp := \&a[n-i+1]
- .\&a[n-i+1] := \&a[i]
- .\&a[i] := \m(tmp)
- }
-
- which reduces the backslash count to less than half. The final
- statement in the loop could be written ".\&a[i] ::= tmp" if the array
- contained only numbers (since ::= indicates arithmetic expression
- evaluation).
-
- Also, now you can use floating-point numbers in integer contexts (such
- as array subscripts), in which case they are truncated to an integer
- value (i.e. the fractional part is discarded).
-
- Examples of numeric contexts include:
-
- * Array subscripts.
- * Any numeric function argument.
- * Right-hand side of ::= assignments.
- * EVALUATE command or \fevaluate() function expression.
- * The INCREMENT or DECREMENT by-value.
- * IF =, >, <, !=, >=, and <= comparands.
- * The IF number construct.
- * FOR-loop variables.
- * STOP, END, and EXIT status codes.
- * The INPUT timeout value.
- * PAUSE, WAIT, SLEEP, MSLEEP intervals.
- * The SHIFT argument.
- * Numeric switch arguments, e.g. TYPE /WIDTH:number, SEND
- /LARGER:number.
- * SCREEN MOVE-TO row and column number.
- * Various SET DIAL parameters (timeout, retry limit, etc).
- * Various SET SEND or RECEIVE parameters (packet length, window
- size, etc).
- * Various other SET parameters.
-
- and:
-
- * S-Expressions (explained in [399]Section 9).
-
- Macro names used in numeric contexts must not include mathematical
- operators. Although it is legal to create a macro called "foo+bar", in
- a numeric context this would be taken as the sum of the values of
- "foo" and "bar". Any such conflict can be avoided, of course, by
- enclosing the macro name in \m(...).

-
- 8.3. New IF Conditions
-
- Several new IF conditions are available:
-
- IF DECLARED arrayname
- Explained in [404]Section 8.6.
-
- IF KBHIT
- Allows a script to test whether a key was pressed without
- actually trying to read it.
-
- IF KERBANG (Unix only)
- True if Kermit was started from a Kerbang script. This is
- useful for knowing how to interpret the \&@[] and \&_[]
- argument vector arrays, and under what conditions to exit.
-
- IF INTEGER n
- This is just a synonym for IF NUMERIC, which is true if n
- contains only digits (or, if n is a variable, its value
- contains only digits).
-
- By contrast, IF FLOAT n succeeds if n is a floating-point number OR an
- integer (or a variable with floating-point or integer value).
- Therefore, IF FLOAT should be used whenever any kind of number is
- acceptable, whereas IF INTEGER (or IF NUMERIC) when only an integer
- can be used.

-
- 8.4. The ON_UNKNOWN_COMMAND Macro
-
- The new ON_UNKNOWN_COMMAND macro, if defined, is executed whenever you
- give a command that is not known to C-Kermit; any operands are passed
- as arguments. Here are some sample definitions:
-
- DEF ON_UNKNOWN_COMMAND telnet \%1 ; Treat unknown commands as hostnames
- DEF ON_UNKNOWN_COMMAND dial \%1 ; Treat unknown commands phone numbers
- DEF ON_UNKNOWN_COMMAND take \%1 ; Treat unknown commands as filenames
- DEF ON_UNKNOWN_COMMAND !\%* ; Treat unknown commands as shell commands
-
- The ON_CD macro, if defined, is executed whenever Kermit is given a CD
- (change directory) command (8.0.211). Upon entry to this macro, the
- directory has already changed and the new directory string is
- available in the \v(directory) variable, and also as the first
- argument (\%1).

-
- 8.5. The SHOW MACRO Command
-
- The SHOW MACRO command has been changed to accept more than one macro
- name:
-
- (setq a 1 b 2 c 3)
- show mac a b c
- a = 1
- b = 2
- c = 3
-
- An exact match is required for each name (except that case doesn't
- matter). If you include wildcard characters, however, a pattern match
- is performed:
-
- show mac [a-c]*x
-
- shows all macros whose names start with a, b, or c, and end with x.

-
- 8.6. Arrays
-
- A clarification regarding references to array names (as opposed to
- array elements): You can use array-name "abbreviations" like &a only
- in contexts that expect array names, like ARRAY commands or array-name
- function arguments such as the second argument of \fsplit(). In a
- LOCAL statement, however, you have to write \&a[], since "local &a"
- might refer to a macro named "&a".
-
- In function arguments, however, you MUST use the abbreviated form:
- \fsplit(\%a,&a) or \fsplit(\%a,&a[]). If you include the backslash (as
- in "\fsplit(\%a,\&a[])") a parse error occurs.
-
- Here are the new array-related commands:
-
- IF DECLARED arrayname
- Allows a script to test whether an array has been declared. The
- arrayname can be a non-array backslash variable such as \%1 or
- \m(name), in which case it is evaluated first, and the result
- is treated as the array name. Otherwise, arrayname is treated
- as in the ARRAY commands: it can be a, &a, &a[], \&a, \&a[],
- \&a[3], \&a[3:9], etc, with the appropriate results in each
- case. Synonym: IF DCL.
-
- UNDECLARE arrayname
- UNDECLARE is a new top-level command to undeclare an array.
- Previously this could only be done with "declare \&a[0]" (i.e.
- re-declare the array with a dimension of 0).
-
- ARRAY LINK linkname arrayname
- Creates a symbolic link from the array named by linkname (which
- must be the name of an array that is not yet declared in the
- current context) to the array named by arrayname (which must
- the name of a currently declared array that is not itself a
- link, or a variable containing the name of such an array). The
- two names indicate the same array: if you change an array
- element, the change is reflected in the link too, and vice
- versa. If you undeclare the link, the real array is unaffected.
- If you undeclare the real array, all links to it disappear. If
- you resize an array (directly or through a link), all links to
- it are updated automatically.
-
- Array links let you pass array names as arguments to macros. For
- example, suppose you had a program that needed to uppercase all the
- elements of different arrays at different times. You could write a
- macro to do this, with the array name as an argument. But without
- array links, there would be no way to refer to the argument array
- within the macro. Array links make it easy:
-
- define arrayupper {
- local \&e[] \%i
- array link \&e[] \%1
- for i 1 \fdim(&e) 1 { .\&e[i] := \fupper(\&e[i]) }
- }
- declare \&a[] = these are some words
- arrayupper &a
- show array &a
-
- The macro declares the array link LOCAL, which means it doesn't
- conflict with any array of the same name that might exist outside the
- macro, and that the link is destroyed automatically when the macro
- exits. This works, by the way, even if the link name and the macro
- argument name are the same, as long as the link is declared LOCAL.
-
- As noted, you can't make a link to a nonexistent array. So when
- writing a macro whose job is to create an array whose name is passed
- as an argument, you must declare the array first (the size doesn't
- matter as long as it's greater than 0). Example:
-
- define tryme { ; Demonstration macro
- local \&e[] ; We only need this inside the macro
- array link \&e[] \%1 ; Make local link
- shift ; Shift argument list
- void \fsplit(\%*,&e) ; Split remainder of arg list into array
- }
- declare \&a[1] ; Declare target array in advance
- tryme &a here are some words ; Invoke the macro with array name and words
- show array a ; See the results
-
- One final improvement allows the macro itself to declare the array
- (this was not possible in earlier Kermit releases): if the array name
- in the DECLARE command is a variable (and not an array name), or
- includes variables, the resulting value is used as the array name. So:
-
- define tryme { ; Demonstration macro
- declare \%1[1] ; Preliminary declaration for target array
- local \&e[] ; We only need this inside the macro
- array link \&e[] \%1 ; Make local link
- shift ; Shift argument list
- void \fsplit(\%*,&e) ; Split remainder of arg list into array
- }
- tryme &a here are some words ; Invoke the macro with array name and words
- show array a ; See the results
-
- The SHOW ARRAY command now indicates whether an array name is a link.
-
- Also see the descriptions of [417]\fjoin() and [418]\fsplit(), plus
- [419]Section 8.10 on the MINPUT command, which shows how an entire
- array (or segment of it) can be used as the MINPUT target list.

-
- The following new or improved built-in functions are available:
-
- \fcmdstack() Allows programmatic access to the command stack.
- \fcvtdate() [437]Section 8.13, format options added
- \fdelta2secs() [438]Section 8.13
- \fdostounixpath(s1) Converts a DOS filename to Unix format.
- \fsplit() Now allows grouping/nesting in source string.
- \fword() Allows the same grouping and nesting.
- \fjoin(&a,s1,n1,n2) Copies an array into a single string.
- \fsubstitute(s1,s2,s3) Substitutes characters within a string.
- \freplace() Has new 4th "occurrence" argument.
- \fsexpression() Evaluates an S-Expression (explained in [439]Section
-9).
- \ftrim(), \fltrim() Now trim CR and LF by default, as well as SP and Tab.
- \funixtodospath(s1) Converts a Unix filename to DOS format.
- \fkeywordval(s1,c1) Assigns values to keywords (macros) (explained below)
-.
-
- Most functions that have "2" in their names to stand for the word "to"
- can now also be written with "to", e.g. "\fdelta2secs(),"
- \fdeltatosecs()."
-
- \funtabify(string)
- (New to 8.0.211) Replaces Horizontal Tab characters in the
- given string with spaces based on VT100-like tab stops.
-
- \fverify(s1,s2,n)
- As of version 8.0.211, returns -1 if s2 is an empty string.
- Previously it returned 0, making \fverify(abc,\%a) look as if
- \%a was a string combosed of a's, b's, and/or c's when in fact
- it contained nothing.
-
- \fcode(string)
- As of version 8.0.211, returns 0 if string is empty or missing.
- Previously it returned the empty string, which made it unsafe
- to use in arithmetic or boolean expressions.
-
- \v(inscale)
- New to version 8.0.211, its value is the INPUT SCALE-FACTOR
- ([440]Section 8.10), default 1.0.
-
- 8.7.1. The \fkeywordval() Function
-
- \fkeywordval(s1,c1) is new to C-Kermit 8.0. Given a string s1 of the
- form "name=value", it creates a macro with the given name and assigns
- it the given value. If no value appears after the equal sign, any
- existing macro of the given name is undefined. Blanks are
- automatically trimmed from around the name and value. The optional c1
- parameter is the assignment operator character, equal sign (=) by
- default. This function is handy for processing keyword parameters or
- any other form of parameter-value pair. Suppose, for example, you want
- to write a macro that accepts keyword parameters rather than
- positional ones:
-
- define MYDIAL {
- local \%i modem hangup method device speed number
- def number 5551234 ; Assign default parameter values
- def speed 57600
- def modem usrobotics
- def hangup rs232
- def method tone
- def country 1
- for \%i 1 \v(argc)-1 1 { ; Parse any keyword parameters...
- if not \fkeywordval(\&_[\%i]) end 1 Bad parameter: "\&_[\%i]"
- }
- set dial country \m(country)
- set modem type \m(modem)
- set modem hang \m(hangup)
- set dial method \m(tone)
- set line \m(device)
- if fail stop 1
- set speed \m(speed)
- if fail stop 1
- show comm
- set dial display on
- dial \m(number)
- if success connect
- }
-
- In this example, all the defaults are set up inside the macro, and
- therefore it can be invoked with no parameters at all. But if you want
- to have the macro dial a different number, you can supply it as
- follows:
-
- mydial number=7654321
-
- You can supply any number of keyword parameters, and you can give them
- in any order:
-
- mydial number=7654321 hangup=modem speed=115200
-
- 8.7.2. The \fsplit(), \fjoin(), and \fword() Functions
-
- \fjoin(&a,s1,n1,n2) is also new; it creates a string from an array (or
- a piece of one). &a is the name of the array (a range specifier can be
- included); s1 is a character or string to separate each element in the
- result string (can be omitted, in which case the elements are not
- separated at all), and n1 is a grouping mask, explained below. If s1
- is empty or not specified, the array elements are separated with
- spaces. If you want the elements concatenated with no separator,
- include a nonzero n2 argument. Given the array:
-
- declare \&a[] = 0 1 2 3 4 5 6 7 8 9
-
- you can get effects like this:
-
- \fjoin(&a) 0 1 2 3 4 5 6 7 8 9
- \fjoin(&a,:) 0:1:2:3:4:5:6:7:8:9
- \fjoin(&a,{,}) 0,1,2,3,4,5,6,7,8,9
- \fjoin(&a,...) 0...1...2...3...4...5...6...7...8...9
- \fjoin(&a,,,1) 0123456789
-
- \fsplit(), \fword(), \fstripb(), and \fjoin() accept a "grouping mask"
- argument, n1, which is a number from 0 to 63, in which:
-
- 1 = "" doublequotes
- 2 = {} braces
- 4 = '' singlequotes
- 8 = () parentheses
- 16 = [] square brackets
- 32 = <> angle brackets
-
- These can be OR'd (added) together to make any number 0-63 (-1 is
- treated the same as 63, 0 means no grouping). If a bit is on, the
- corresponding kind of grouping is selected. (If more than 1 bit is set
- for \fjoin(), only the lowest-order one is used.)
-
- If you include the same character in the grouping mask and the include
- list, the grouping mask takes precedence. Example:
-
- def \%a a "b c d" e
- \fsplit(\%a,&a[],,,-1) = 3 <-- doublequote used for grouping
- \fsplit(\%a,&a[],,",-1) = 3 <-- doublequote still used for grouping
-
- Nesting of matched left and right grouping characters (parentheses,
- braces, and brackets, but not quotes) is recognized. Example:
-
- def \%a a (b c <d e [f g {h i} j k] l m> n o) p
- \fsplit(\%a,&a,,,0) = 16 (no grouping)
- \fsplit(\%a,&a,,,2) = 15 (braces only)
- \fsplit(\%a,&a,,,16) = 11 (square brackets only)
- \fsplit(\%a,&a,,,32) = 7 (angle brackets only)
- \fsplit(\%a,&a,,,63) = 3 (all)
- \fsplit(\%a,&a,,,-1) = 3 (all)
-
- \fsplit() and \fjoin() are "reciprocal" functions. You can split a
- string up into an array and join it back into a new string that is
- equivalent, as long as \fsplit() and \fjoin() are given equivalent
- grouping masks, except that the type of braces might change. Example:
-
- def \%a a {b c [d e] f g} "h i" j <k l> m
- echo STRING=[\%a]
- echo WORDS=\fsplit(\%a,&a,,,-1)
- show array a
- asg \%b \fjoin(&a,{ },2)
- echo JOIN =[\%b]
- echo WORDS=\fsplit(\%b,&b,,,-1)
- show array b
-
- The arrays a and b are identical. The strings a and b are as follows:
-
- \%a: a {b c [d e] f g} "h i" j <k l> m
- \%b: a {b c [d e] f g} {h i} j {k l} m
-
- It is possible to quote separator grouping characters with backslash
- to override their grouping function. And of course to include
- backslash itself in the string, it must be quoted too. Furthermore,
- each backslash must be doubled, so the command parser will still pass
- one backslash to \fsplit() for each two that it sees. Here are some
- examples using \fsplit() with a grouping mask of 8 (treat parentheses
- as grouping characters).
-
- String Result
- a b c d e f 6
- a b\\ c d e f 5
- a b (c d e) f 4
- a b \\(c d e\\) f 6
- a b \\\\(c d e\\\\) f 7
-
- \fsplit() has also been changed to create its array (if one is given)
- each time it is called, so now it can be conveniently called in a loop
- without having to redeclare the array each time.
-
- Incidentally... Sometimes you might want to invoke \fsplit() in a
- situation where you don't care about its return value, e.g. when you
- just want to fill the array. Now you can "call" \fsplit() or any other
- function with the new [441]VOID command:
-
- void \fsplit(\%a,&a)
-
- \fsplit() and \fjoin() also accept a new, optional 6th argument, an
- options flag, a number that can specify a number of options. So far
- there is just one option, whose value is 1:
-
- separator-flag
- Normally separators are collapsed. So, for example,
-
- \fword(Three little words,2)
-
- returns "little" (the second word). Space is a separator, but
- there are multiple spaces between each word. If the value 1 is
- included in the option flag, however, each separator counts. If
- two separators are adjacent, an empty word is produced between
- them. This is useful for parsing (e.g.) comma-separated lists
- exported from databases or spreadsheets.
-
- 8.7.3. The \fcmdstack() Function
-
- The new \fcmdstack() function gives access to the command stack:
-
- \fcmdstack(n1,n2)
- Arguments: n1 is the command stack level. If omitted, the
- current level, \v(cmdlevel), is used. n2 is a function code
- specifying the desired type of information:
-
- 0 (default) = name of object at level n1.
- 1 (nonzero) = object type (0 = prompt; 1 = command file; 2 = macro).
-
- The default for n2 is 0.
-
- The name associated with prompt is "(prompt)". Here's a loop that can
- be included in a macro or command file to show the stack (similar to
- what the SHOW STACK command does):
-
- for \%i \v(cmdlevel) 0 -1 {
- echo \%i. [\fcmdstack(\%i,1)] \fcmdstack(\%i,0)
- }
-
- In this connection, note that \v(cmdfile) always indicates the most
- recently invoked active command file (if any), even if that file is
- executing a macro. Similarly, \v(macro) indicates the most recently
- invoked macro (if any), even if the current command source is not a
- macro. The name of the "caller" of the currently executing object
- (command file or macro) is:
-
- \fcmdstack(\v(cmdlevel)-1)
-
- and its type is:
-
- \fcmdstack(\v(cmdlevel)-1,1)
-
- To find the name of the macro that invoked the currently executing
- object, even if one or more intermediate command files (or prompting
- levels) are involved, use a loop like this:
-
- for \%i \v(cmdlevel)-1 0 -1 {
- if = \fcmdstack(\%i,1) 2 echo CALLER = \fcmdstack(\%i,0)
- }
-
- Of course if you make a macro to do this, the macro must account for
- its own additional level:
-
- define CALLER {
- for \%i \v(cmdlevel)-2 0 -1 {
- if = \fcmdstack(\%i,1) 2 return \fcmdstack(\%i,0)
- }
- return "(none)"
- }
-
- The built-in variable \v(cmdsource) gives the current command source
- as a word ("prompt", "file", or "macro").
-
- 8.7.4. The VOID Command
-
- VOID is like ECHO in that all functions and variables in its argument
- text are evaluated. but it doesn't print anything (except possibly an
- error message if a function was invocation contained or resulted in
- any errors). VOID sets FAILURE if it encounters any errors, SUCCESS
- otherwise.

- _________________________________________________________________
-
- 8.8. The RETURN and END Commands
-
- The execution of a macro is terminated in any of the following ways:
-
- * With an END [ number [ message ] ] command. If a number is given,
- the macro succeeds if the number is 0, and fails if it is not
- zero; if a number is not given, the macro succeeds.
- * With a STOP command, which works just like END except it peels
- back the command stack all the way to top level.
- * With a RETURN [ text ] command, in which case the macro always
- succeeds.
- * By running out of commands to execute, in which case the macro
- succeeds or fails according the most recently executed command
- that sets success or failure.
-
- The same considerations apply to command files invoked by the TAKE
- command.
-
- If a macro does not execute any commands that set success or failure,
- then invoking the macro does not change the current SUCCESS/FAILURE
- status. It follows, then, that the mere invocation of a macro does not
- change the SUCCESS/FAILURE status either. This makes it possible to
- write macros to react to the status of other commands (or macros), for
- example:
-
- define CHKLINE {
- if success end 0
- stop 1 SET LINE failed - please try another device.
- }
- set modem type usrobotics
- set line /dev/cua0
- chkline
- set speed 57600
- dial 7654321
-
- By the way, none of this is news. But it was not explicitly documented
- before, and C-Kermit 7.0 and earlier did not always handle the RETURN
- statement as it should have.

- 8.9. UNDEFINing Groups of Variables
-
- The UNDEFINE command, which previously accepted one variable name, now
- accepts a list of them, and also accepts wildcard notation to allow
- deletion of variables that match a given pattern.
-
- UNDEFINE [ switches ] name [ name [ name [ ... ] ] ]
- Undefines the variables whose names are given. Up to 64 names
- may be given in one UNDEFINE command.
-
- If you omit the switches and include only one name, the UNDEFINE
- command works as before.
-
- Switches include:
-
- /MATCHING
- Specifies that the names given are to treated as patterns
- rather than literal variable names. Note: pattern matching
- can't be used with array references; use the ARRAY command to
- manipulate arrays and subarrays.
-
- /LIST
- List the name of each variable to be undefined, and whether it
- was undefined successfully ("ok" or "error"), plus a summary
- count at the end.
-
- /SIMULATE
- List the names of the variables that would be deleted without
- actually deleting them. Implies /LIST.
-
- The UNDEFINE command fails if there were any errors and succeeds
- otherwise.
-
- The new _UNDEFINE command is like UNDEFINE, except the names are
- assumed to be variable names themselves, which contain the names (or
- parts of them) of the variables to be undefined. For example, if you
- have the following definitions:
-
- define \%a foo
- define foo This is some text
-
- then:
-
- undef \%a
-
- undefines the variable \%a, but:
-
- _undef \%a
-
- undefines the macro foo.
-
- Normal Kermit patterns are used for matching; metacharacters include
- asterisk, question mark, braces, and square brackets. Thus, when using
- the /MATCHING switch, if the names of the macros you want to undefine
- contain any of these characters, you must quote them with backslash to
- force them to be taken literally. Also note that \%* is not the name
- of a variable; it is a special notation used within a macro for "all
- my arguments". The command "undef /match \%*" deletes all \%x
- variables, where x is 0..9 and a..z. Use "undef /match \%[0-9]" to
- delete macro argument variables or "undef /match \%[i-n]" to delete a
- range of \%x variables.

-
- 8.10. The INPUT and MINPUT Commands
-
- As of C-Kermit 8.0.211, the INPUT and MINPUT commands accept a switch:
-
- [M]INPUT /NOMATCH timeout
- The /NOMATCH switch allows INPUT or MINPUT to read incoming
- material for the specified amount of time, without attempting
- to match it with any text or patterns. When this switch is
- included, the [M]INPUT command succeeds when the timeout
- interval expires, with \v(instatus) set to 1, meaning "timed
- out", or fails upon interruption or i/o error.
-
- Also in version 8.0.211, there is a new way to apply a scale factor to
- [M]INPUT timeouts:
-
- SET INPUT SCALE-FACTOR floating-point-number
- This scales all [M]INPUT timeouts by the given factor, allowing
- time-sensitive scripts to be adjusted to changing conditions
- such as congested networks or different-speed modems without
- having to change each INPUT-class command. This affects only
- those timeouts that are given in seconds, not as wall-clock
- times. Although the scale factor can have a fractional part,
- the INPUT timeout is still an integer. The new built-in
- variable \v(inscale) tells the current INPUT SCALE-FACTOR.
-
- The MINPUT command can be used to search the incoming data stream for
- several targets simultaneously. For example:
-
- MINPUT 8 one two three
-
- waits up to 8 seconds for one of the words "one", "two", or "three" to
- arrive. Words can be grouped to indicate targets that contain spaces:
-
- MINPUT 8 nineteeen twenty "twenty one"
-
- And of course you can also use variables in place of (or as part of)
- the target names:
-
- MINPUT 8 \%a \&x[3] \m(foo)
-
- Until now you had to know the number of targets in advance when
- writing the MINPUT statement. Each of the examples above has exactly
- three targets.
-
- But suppose your script needs to look for a variable number of
- targets. For this you can use arrays and \fjoin(), described in
- [454]Section 8.7. Any number of \fjoin() invocations can be included
- in the MINPUT target list, and each one is expanded into the
- appropriate number of separate targets each time the MINPUT command is
- executed. Example:
-
- declare \&a[10] = one two three
- minput 10 foo \fjoin(&a) bar
-
- This declares an array of ten elements, and assigns values to the
- first three of them. The MINPUT command looks for these three (as well
- as the words "foo" and "bar"). Later, if you assign additional
- elements to the array, the same MINPUT command also looks for the new
- elements.
-
- If an array element contains spaces, each word becomes a separate
- target. To create one target per array element, use \fjoin()'s
- grouping feature:
-
- dcl \&a[] = {aaa bbb} {ccc ddd} {xxx yyy zzz}
-
- minput 10 \fjoin(&a) <-- 7 targets
- minput 10 \fjoin(&a,,2) <-- 3 targets

-
- 8.11. Learned Scripts
-
- C-Kermit now includes a simple script recorder that monitors your
- commands, plus your actions during CONNECT mode, and automatically
- generates a script program that mimics what it observed. You should
- think of this feature as a script-writing ASSISTANT since, as you will
- see [459]later in this section, the result generally needs some
- editing to make it both secure and flexible. The script recorder is
- controlled by the new LEARN command:
-
- LEARN [ /ON /OFF /CLOSE ] [ filename ]
- If you give a filename, the file is opened for subsequent
- recording. The /ON switch enables recording to the current file
- (if any); /OFF disables recording. /CLOSE closes the current
- script recording file (if any). If you give a filename without
- any switches, /ON is assumed.
-
- The /OFF and /ON switches let you turn recording off and on during a
- session without closing the file.
-
- When recording:
-
- * All commands that you type (or recall) at the prompt are recorded
- in the file except:
- + LEARN commands are not recorded.
- + The CONNECT command is not recorded.
- + The TELNET command is converted to SET HOST /NETWORK:TCP.
- * Commands obtained from macros or command files are not recorded.
- * During CONNECT:
- + Every line you type is converted to an OUTPUT command.
- + The last prompt before any line you type becomes an INPUT
- command.
- + Timeouts are calculated automatically for each INPUT command.
- + A PAUSE command is inserted before each OUTPUT command just
- to be safe.
-
- Thus the script recorder is inherently line-oriented. It can't be used
- to script character-oriented interactions like typing Space to a
- "More?" prompt or editing a text file with VI or EMACS.
-
- But it has advantages too; for example it takes control characters
- into account that might not be visible to you otherwise, and it
- automatically converts control characters in both the input and output
- streams to the appropriate notation. It can tell, for example that the
- "$ " prompt on the left margin in UNIX is really {\{13}\{10}$ },
- whereas in VMS it might be {\{13}\{10}\{13}$ }. These sequences are
- detected and recorded automatically.
-
- A learned script should execute correctly when you give a TAKE command
- for it. However, it is usually appropriate to edit the script a bit.
- The most important change would be to remove any passwords from it.
- For example, if the script contains:
-
- INPUT 9 {\{13}\{10}Password: }
- IF FAIL STOP 1 INPUT timeout
- PAUSE 1
- OUTPUT bigsecret\{13}
-
- you should replace this by something like:
-
- INPUT 9 {\{13}\{10}Password: }
- IF FAIL STOP 1 INPUT timeout
- ASKQ pswd Please type your password:
- PAUSE 1
- OUTPUT \m(pswd)\{13}
-
- The LEARN command can't do this for you since it knows nothing about
- "content"; it only knows about lines and can't be expected to parse or
- understand them -- after all, the Password prompt might be in some
- other language. So remember: if you use the LEARN command to record a
- login script, be sure edit the resulting file to remove any passwords.
- Also be sure to delete any backup copies your editor or OS might have
- made of the file.
-
- Other manual adjustments might also be appropriate:
-
- * If the target of an INPUT command can vary, you can replace the
- INPUT command with MINPUT and the appropriate target list, and/or
- the target with a \fpattern(). For example, suppose you are
- dialing a number that can be answered by any one of 100 terminal
- servers, whose prompts are ts-00>, ts-01>, ts-02>, ... ts-99>. The
- script records a particular one of these, but you want it to work
- for all of them, so change (e.g.):
- INPUT 10 ts-23> ; or whatever
- to:
- INPUT 10 \fpattern(ts-[0-9][0-9]>)
- * The INPUT timeout values are conservative, but they are based only
- on a single observation; you might need to tune them.
- * The PAUSE commands might not be necessary, or the PAUSE interval
- might need adjustment.
- * In case you made typographical errors during recording, they are
- incorporated in your script; you can edit them out if you want to.
-
- Here is a sample script generated by Kermit ("learn vms.ksc") in which
- a Telnet connection is made to a VMS computer, the user logs in,
- starts Kermit on VMS, sends it a file, and then logs out:
-
- ; Scriptfile: vms.ksc
- ; Directory: /usr/olga
- ; Recorded: 20001124 15:21:23
-
- SET HOST /NETWORK:TCP vms.xyzcorp.com
- IF FAIL STOP 1 Connection failed
-
- INPUT 7 {\{13}\{10}\{13}Username: }
- IF FAIL STOP 1 INPUT timeout
- PAUSE 1
- OUTPUT olga\{13}
- INPUT 3 {\{13}\{10}\{13}Password: }
- IF FAIL STOP 1 INPUT timeout
- PAUSE 1
- OUTPUT secret\{13}
- INPUT 18 {\{13}\{10}\{13}$ }
- IF FAIL STOP 1 INPUT timeout
- PAUSE 1
- OUTPUT set default [.incoming]\{13}
- INPUT 12 {\{13}\{10}\{13}$ }
- IF FAIL STOP 1 INPUT timeout
- PAUSE 1
- OUTPUT kermit\{13}
- INPUT 15 {\{13}\{10}\{13}ALTO:[OLGA.INCOMING] C-Kermit>}
- IF FAIL STOP 1 INPUT timeout
- PAUSE 1
- OUTPUT receive\{13}
- send myfile.txt
-
- INPUT 18 {\{13}\{10}\{13}ALTO:[OLGA.INCOMING] C-Kermit>}
- IF FAIL STOP 1 INPUT timeout
- PAUSE 1
- OUTPUT exit\{13}
- INPUT 6 {\{13}\{10}\{13}$ }
- IF FAIL STOP 1 INPUT timeout
- PAUSE 1
- OUTPUT logout\{13}
- close
- exit
-
- The commands generated by Kermit during CONNECT (INPUT, IF FAIL,
- PAUSE, and OUTPUT) have uppercase keywords; the commands typed by the
- user are in whatever form the user typed them (in this case,
- lowercase).

- 8.12. Pattern Matching
-
- A pattern is a character string that is used to match other strings.
- Patterns can contain metacharacters that represent special actions
- like "match any single character", "match zero or more characters",
- "match any single character from a list", and so on. The best known
- application of patterns is in file specifications that contain
- wildcards, as in "send *.txt", meaning "send all files whose names end
- with .txt".
-
- Patterns are also used in increasingly many other ways, to the extent
- it is useful to point out certain important distinctions in the ways
- in which they are used:
-
- Anchored Patterns
- If an anchored pattern does not begin with "*", it must match
- the beginning of the string, and if it does not end with "*",
- it must match the end of the string. For example, the anchored
- pattern "abc" matches only the string "abc", not "abcde" or
- "xyzabc" or "abcabc". The anchored pattern "abc*" matches any
- string that starts with "abc"; the anchored pattern "*abc"
- matches any string that ends with "abc"; the anchored pattern
- "*abc*" matches any string that contains "abc" (including any
- that start and/or end with it).
-
- Floating Patterns
- A floating pattern matches any string that contains a substring
- that matches the pattern. In other words, a floating pattern
- has an implied "*" at the beginning and end. You can anchor a
- floating pattern to the beginning by starting it with "^", and
- you can anchor it to the end by ending it with "$" (see
- examples below).
-
- Wildcards
- A wildcard is an anchored pattern that has the additional
- property that "*" does not match directory separators.
-
- This terminology lets us describe Kermit's commands with a bit more
- precision. When a pattern is used for matching filenames, it is a
- wildcard, except in the TEXT-PATTERNS and BINARY-PATTERNS lists and
- /EXCEPT: clauses, in which case directory separators are not
- significant (for example, a BINARY-PATTERN of "*.exe" matches any file
- whose name ends in .exe, no matter how deeply it might be buried in
- subdirectories). When Kermit parses a file specification directly,
- however, it uses the strict wildcard definition. For example, "send
- a*b" sends all files whose names start with "a" and end with "b" in
- the current directory, and not any files whose names end with "b" that
- happen to be in subdirectories whose names start with "a". And as
- noted, wildcards are anchored, so "delete foo" deletes the file named
- "foo", and not all files whose names happen to contain "foo".
-
- Most other patterns are anchored. For example:
-
- if match abc bc ...
-
- does not succeed (and you would be surprised if it did!). In fact, the
- only floating patterns are the ones used by commands or functions that
- search for patterns in files, arrays, or strings. These include:
-
- * The GREP and TYPE /MATCH commands.
- * The \fsearch(), \frsearch(), and \farraylook() functions.
-
- Thus these are the only contexts in which explicit anchors ("^" and
- "$") may be used:
-
- grep abc *.txt
- Prints all lines containing "abc" in all files whose names end
- with ".txt".
-
- grep ^abc *.txt
- Prints all lines that start with "abc" in all ".txt" files.
-
- grep abc$ *.txt
- Prints all lines that end with "abc" in all ".txt" files.
-
- grep ^a*z$ *.txt
- Prints all lines that start with "a" and end with "z" in all
- ".txt" files.
-
- Similarly for TYPE /PAGE, /fsearch(), /frsearch(), and \farraylook().
-
- Here is a brief summary of anchored and floating pattern equivalences:
-
- Anchored Floating
- abc ^abc$
- *abc abc$
- abc* ^abc
- *abc* abc

-
- 8.13. Dates and Times
-
- C-Kermit's comprehension of date-time formats is considerably expanded
- in version 8.0. Any command that reads dates, including the DATE
- command itself, or any switch, such as the /BEFORE: and /AFTER:
- switches, or any function such as \fcvtdate(), now can understand
- dates and times expressed in any ISO 8601 format, in Unix "asctime"
- format, in FTP MDTM format, and in practically any format used in RFC
- 822 or RFC 2822 electronic mail, with or without timezones, and in a
- great many other formats as well. HELP DATE briefly summarizes the
- acceptable date-time formats.
-
- Furthermore, C-Kermit 8.0 includes a new and easy-to-use form of
- date-time arithmetic, in which any date or time can be combined with a
- "delta time", to add or subtract the desired time interval (years,
- months, weeks, days, hours, minutes, seconds) to/from the given date.
- And new functions are available to compare dates and to compute their
- differences.
-
- As you can imagine, all this requires quite a bit of "syntax". The
- basic format is:
-
- [ date ] [ time ] [ delta ]
-
- Each field is optional, but in most cases (depending on the context)
- there must be at least one field. If a date is given, it must come
- first. If no date is given, the current date is assumed. If no time is
- given, an appropriate time is supplied depending on whether a date was
- supplied. If no delta is given, no arithmetic is done. If a delta is
- given without a date or time, the current date and time are used as
- the base.
-
- Date-time-delta fields are likely to contain spaces (although they
- need not; space-free forms are always available). Therefore, in most
- contexts -- and notably as switch arguments -- date-time information
- must be enclosed in braces or doublequotes, for example:
-
- send /after:"8-Aug-2001 12:00 UTC" *.txt
-
- Kermit's standard internal format for dates and times is:
-
- yyyymmdd hh:mm:ss
-
- for example:
-
- 20010208 10:28:01
-
- Date-times can always be given in this format. yyyy is the 4-digit
- year, mm is the two-digit month (1-12; supply leading zero for
- Jan-Sep), dd is the 2-digit day (leading zero for 1-9), hh is the hour
- (0-23), mm the minute (0-59), ss the second (0-59), each with leading
- zero if less than the field width. The date and time can be separated
- by a space, an underscore, a colon, or the letter T. The time is in
- 24-hour format. Thus the various quantites are at the following fixed
- positions:
-
-Position Contents
- 1-4 Year (4 digits, 0000-9999)
- 5-6 Month (2 digits, 1-12)
- 7-8 Day (2 digits, 1-31)
- 9 Date-Time Separator (space, :, _, or the letter T)
- 10-11 Hour (2 digits, 0-23)
- 12 Hour-Minute Separator (colon)
- 13-14 Minute (2 digits, 0-59)
- 15 Minute-Second Separator (colon)
- 16-17 Second (2 digits, 0-59)
-
- Example:
-
- 19800526 13:07:12 26 May 1980, 13:07:12 (1:07:12PM)
-
- This is the format produced by the DATE command and by any function
- that returns a date-time. It is suitable for lexical comparison and
- sorting, and for use as a date-time in any Kermit command. When this
- format is given as input to a command or function, various date-time
- separators (as noted) are accepted:
-
- 19800526 13:07:12 26 May 1980, 13:07:12 (1:07:12PM)
- 20010208_10:28:35 2 February 2001, 10:28:35 AM
- 18580101:12:00:00 1 January 1858, noon
- 20110208T00:00:00 2 February 2011, midnight
-
- Certain other special date-time formats that are encountered on
- computer networks are recognized:
-
- Asctime Format
- This is a fixed format used by Unix, named after Unix's
- asctime() ("ASCII time") function. It is always exactly 24
- characters long. Example: Fri Aug 10 16:38:01 2001
-
- Asctime with Timezone
- This is like Asctime format, but includes a 3-character
- timezone between the time and year. It is exactly 28 characters
- long. Example: Fri Aug 10 16:38:01 GMT 2001
-
- E-Mail Format
- E-mail date-time formats are defined in [468]RFC 2822 with a
- fair amount of flexibility and options. The following examples
- are typical of e-mails and HTTP (web-page) headers:
-
- Sat, 14 Jul 2001 11:49:29 (No timezone)
- Fri, 24 Mar 2000 14:19:59 EST (Symbolic timezone)
- Tue, 26 Jun 2001 10:19:45 -0400 (EDT) (GMT Offset + comment)
-
- FTP MDTM Format
- This is the date-time format supplied by FTP servers that
- support the (not yet standard but widely used nevertheless)
- MDTM command, by which the FTP client asks for a file's
- modification time:
-
- yyyymmddhhmmss[.ffff]
-
- where yyyy is the 4-digit year, mm is the 2-digit month, and so
- on, exactly 14 digits long. An optional fractional part
- (fraction of second) may also be included, separated by a
- decimal point (period). Kermit rounds to the nearest second.
- Example:
-
- 20020208102835.515 (8 February 2002 10:28:36 AM)
-
- 8.13.1. The Date
-
- The date, if given, must precede the time and/or delta, and can be in
- many, many formats. For starters, you can use several symbolic date
- names in place of actual dates:
-
- NOW
- This is replaced by the current date and time. The time can not
- be overriden (if you want to supply a specific time, use TODAY
- rather than NOW).
-
- TODAY
- This is replaced by the current date and a default time of
- 00:00:00 is supplied, but can be overridden by a specific time;
- for example, if today is 8 February 2002, then "TODAY" is
- "20020802 00:00:00" but "TODAY 10:28" is "20020802 10:28:00".
-
- TOMORROW
- Like TODAY, but one day later (if today is 8 February 2002,
- then "TOMORROW" is "20020803 00:00:00" but "TOMORROW 16:30" is
- "20020803 16:30:00").
-
- YESTERDAY
- Like TODAY, but one day earlier.
-
- MONDAY, TUESDAY, WEDNESDAY, ..., SUNDAY
- The date on the given day of the week, today or later. A
- default time of 00:00:00 is supplied but can be overridden.
- Example: "SATURDAY 12:00" means next Saturday (or today, if
- today is Saturday) at noon.
-
- You can give an explicit date in almost any conceivable format, but
- there are some rules:
-
- * If a date is given, it must have three fields: day, month, and
- year; the order can vary (except that the month can not be last).
- * If names are used for days, months, etc, they must be English.
- * The year must lie between 0000 and 9999, inclusive.
- * All calendar calculations use Gregorian dating, so calculated
- dates for years prior to 1582 (or later, depending on the country)
- will not agree with historical dates. Other forms of dating (e.g.
- Hebrew, Chinese) are not supported.
-
- Various date-field separators are accepted: hyphen, slash, space,
- underscore, period. The same field separator (if any) must be used in
- both places; for example 18-Sep-2001 but not 18-Sep/2001. Months can
- be numeric (1-12) or English names or abbreviations. Month name
- abbreviations are normally three letters, e.g. Apr, May, Jun, Jul.
- Capitalization doesn't matter.
-
- Here are a few examples:
-
- 18 Sep 2001 (English month, abbreviated)
- 18 September 2001 (English month, spelled out)
- 2001 Sept 18 (Year, month, day)
- 18-Sep-2001 (With hyphens)
- 18/09/2001 (All numeric with slashes)
- 18.09.2001 (Ditto, with periods)
- 18_09_2001 (Ditto, with underscores)
- 09/18/2001 (See below)
- 2001/09/18 (See below)
- September 18, 2001 (Correspondence style)
- Sep-18-2001 (Month-day-year)
- 20010918 (Numeric, no separators)
-
- You can also include the day of the week with a specific date, in
- which case it is accepted (if it is a valid day name), but not
- verified to agree with the given date:
-
- Tue, 18 Sep 2001 (Abbreviated, with comma)
- Tue,18 Sep 2001 (Comma but no space)
- Tue 18 Sep 2001 (Abbreviated, no comma)
- Tuesday 18 Sep 2001 (Spelled out)
- Tuesday, 18 Sep 2001 (etc)
- Friday, 18 Sep 2001 (Accepted even if not Friday)
-
- In all-numeric dates with the year last, such as 18/09/2001, Kermit
- identifies the year because it's 4 digits, then decides which of the
- other two numbers is the month or day based on its value. If both are
- 12 or less and are unequal, the date is ambiguous and is rejected. In
- all-numeric dates with the year first, the second field is always the
- month and the third is the day. The month never comes last. A date
- with no separators is accepted only if it is all numeric and has
- exactly eight digits, and is assumed to be in yyyymmdd format.
-
- 20010918 (18-Sep-2001 00:00:00)
-
- or 14 digits (as in FTP MDTM format):

-
- You can always avoid ambiguity by putting the year first, or by using
- an English, rather than numeric, month. A date such as 09/08/2001
- would be ambiguous but 2001/09/08 is not, nor is 09-Aug-2001.
-
- Until the late 1990s, it was common to encounter 2-digit years, and
- these are found to this day in old e-mails and other documents. Kermit
- accepts these dates if they have English months, and interprets them
- according to the windowing rules of [469]RFC 2822: "If a two digit
- year is encountered whose value is between 00 and 49, the year is
- interpreted by adding 2000, ending up with a value between 2000 and
- 2049. If a two digit year is encountered with a value between 50 and
- 99, or any three digit year is encountered, the year is interpreted by
- adding 1900."
-
- If you need to specify a year prior to 1000, use leading zeros to
- ensure it is not misinterpreted as a "non-Y2K-compliant" modern year:
-
- 7-Oct-77 (19771007 00:00:00)
- 7-Oct-0077 (00771007 00:00:00)
-
- 8.13.2. The Time
-
- The basic time format is hh:mm:dd; that is hours, minutes, seconds,
- separated by colons, perhaps with an optional fractional second
- separated by a decimal point (period). The hours are in 24-hour
- format; 12 is noon, 13 is 1pm, and so on. Fields omitted from the
- right default to zero. Fields can be omitted from the left or middle
- by including the field's terminating colon. Examples:
-
- 11:59:59 (11:59:59 AM)
- 11:59 (11:59:00 AM)
- 11 (11:00:00 AM)
- 11:59:59.33 (11:59:59 AM)
- 11:59:59.66 (Noon)
- 03:21:00 (3:21:00 AM)
- 3:21:00 (3:21:00 AM)
- 15:21:00 (3:21:00 PM)
- :21:00 (00:21:00 AM)
- ::01 (00:00:01 AM)
- 11::59 (11:00:59 AM)
-
- Leading zeros can be omitted, but it is customary and more readable to
- keep them in the minute and second fields:
-
- 03:02:01 (03:02:01 AM)
- 3:02:01 (03:02:01 AM)
- 3:2:1 (03:02:01 AM)
-
- AM/PM notation is accepted if you wish to use it:
-
- 11:59:59 (11:59:59 AM)
- 11:59:59AM (11:59:59 AM)
- 11:59:59A.M. (11:59:59 AM)
- 11:59:59am (11:59:59 AM)
- 11:59:59a.m. (11:59:59 AM)
- 11:59:59PM (11:59:59 PM = 23:59:59)
- 11:59:59P.M. (11:59:59 PM = 23:59:59)
- 11:59:59pm (11:59:59 PM = 23:59:59)
- 11:59:59p.m. (11:59:59 PM = 23:59:59)
-
- You can omit the colons if you wish, in which case Kermit uses the
- following rules to interpret the time:
-
- 1. 6 digits is hh:mm:ss, e.g. 123456 is 12:34:56.
- 2. 5 digits is h:mm:ss, e.g. 12345 is 1:23:45.
- 3. 4 digits is hh:mm, e.g. 1234 is 12:34.
- 4. 3 digits is h:mm, e.g. 123 is 1:23.
- 5. 2 digits is hh, e.g. 12 is 12:00.
- 6. 1 digit is h (the hour), e.g. 1 is 1:00.
-
- Examples:
-
- 1 (01:00:00 AM)
- 10 (10:00:00 AM)
- 230 (02:30:00 AM)
- 230pm (02:30:00 PM = 14:30:00)
- 1115 (11:15:00 AM)
- 2315 (11:15:00 PM = 23:15:00 PM)
- 23150 (02:31:50 AM)
- 231500 (23:15:00 PM)
-
- 8.13.3. Time Zones
-
- If a time is given, it can (but need not) be followed by a time zone
- designator. If no time zone is included, the time is treated as local
- time and no timezone conversions are performed.
-
- The preferred time zone designator is the UTC Offset, as specified in
- [470]RFC 2822: a plus sign or minus sign immediately followed by
- exactly four decimal digits, signifying the difference in hh (hours)
- and mm (minutes) from Universal Coordinated Time (UTC, also known as
- Greenwich Mean Time, or GMT), with negative numbers to the West and
- positive numbers to the East. For example:
-
- Fri, 13 Jul 2001 12:54:29 -0700
-
- indicates a local time of 12:54:29 that is 07 hours and 00 minutes
- behind (less than, East of) Universal Time. The space is optional, so
- the example could also be written as:
-
- Fri, 13 Jul 2001 12:54:29-0700
-
- The following symbolic time zones are also accepted, as specified by
- [471]RFC 2822 and/or in ISO 8601:
-
- GMT = +0000 Greenwich Mean Time
- Z = +0000 Zulu (Zero Meridian) Time
- UTC = +0000 Universal Coordinated Time
- UT = +0000 Universal Time
- EDT = -0400 Eastern (USA) Daylight Time
- EST = -0500 Eastern (USA) Standard Time
- CDT = -0500 Central (USA) Daylight Time
- CST = -0600 Central (USA) Standard Time
- MDT = -0600 Mountain (USA) Daylight Time
- MST = -0700 Mountain (USA) Standard Time
- PDT = -0700 Pacific (USA) Daylight Time
- PST = -0800 Pacific (USA) Standard Time
-
- Note that GMT, Z, UTC, and UT all express the same concept: standard
- (not daylight) time at the Zero Meridian. UTC, by the way, is an
- international standard symbol and does not correspond to the order of
- the English words, Universal Coordinated Time, but it happens to have
- the same initial letters as these words. Of course hundreds of other
- symbolic timezones and variations exist, but they are not
- standardized, and are therefore not supported by Kermit.
-
- When a time zone is included with a time, the time is converted to
- local time. In case the conversion crosses a midnight boundary, the
- date is adjusted accordingly. Examples converting to EST (Eastern USA
- Standard Time = -0500):
-
- 11:30:00 = 11:30:00
- 11:30:00 EST = 11:30:00
- 11:30:00 GMT = 06:30:00
- 11:30:00 PST = 14:30:00
- 11:30:00Z = 06:30:00
- 11:30PM GMT = 18:30:00
- 11:30 -0500 = 11:30:00
- 11:30 -0800 = 08:30:00
- 11:30 +0200 = 04:30:00
-
- Unlike most of Kermit's other date-time conversions, timezone
- knowledge (specifically, the offset of local time from UTC) is
- embodied in the underlying operating system, not in Kermit itself, and
- any conversion errors in this department are the fault of the OS. For
- example, most UNIX platforms do not perform conversions for years
- prior to 1970.
-
- 8.13.4. Delta Time
-
- Date/time expressions can be composed of a date and/or time and a
- delta time, or a delta time by itself. When a delta time is given by
- itself, it is relative to the current local date and time. Delta times
- have the following general format:
-
- {+,-}[number units][hh[:mm[:ss]]]
-
- In other words, a delta time always starts with a plus or minus sign,
- which is followed by a "part1", a "part2", or both. The "part1", if
- given, specifies a number of days, weeks, months, or years; "part2"
- specifies a time in hh:mm:ss notation. In arithmetic terms, these
- represents some number of days or other big time units, and then a
- fraction of a day expressed as hours, minutes, and seconds; these are
- to be added to or subtracted from the given (or implied) date and
- time. The syntax is somewhat flexible, as shown by the following
- examples:
-
- +1 day (Plus one day)
- +1day (Ditto)
- +1d (Ditto)
- + 1 day (Ditto)
- + 1 day 3:00 (Plus one day and 3 hours)
- +1d3:00 (Ditto)
- +1d3 (Ditto)
- +3:00:00 (Plus 3 hours)
- +3:00 (Ditto)
- +3 (Ditto)
- +2 days (Plus 2 days)
- -12 days 7:14:22 (Minus 12 days, 7 hours, 14 minutes, and 22 seconds)
-
- The words "week", "month", and "year" can be used like "day" in the
- examples above. A week is exactly equivalent to 7 days. When months
- are specified, the numeric month number of the date is incremented or
- decremented by the given number, and the year and day adjusted
- accordingly if necessary (for example, 31-Jan-2001 +1month =
- 03-Mar-2001 because February does not have 31 days). When years are
- specified, they are added or subtracted to the base year. Examples
- (assuming the current date is 10-Aug-2001 and the current time is
- 19:21:11):
-
- 18-Sep-2001 +1day (20010918 00:00:00)
- today +1day (20010811 00:00:00)
- now+1d (20010811 19:21:11)
- + 1 day (20010811 19:21:11)
- + 1 day 3:14:42 (20010811 22:35:54)
- + 7 weeks (20010928 19:21:11)
- +1d3:14:42 (20010811 22:35:54)
- +1w3:14:42 (20010817 22:35:54)
- +1m3:14:42 (20010910 22:35:54)
- +1y3:14:42 (20020810 22:35:54)
- 2 feb 2001 + 10 years (20110208 00:00:00)
- 2001-02-08 +10y12 (20110208 12:00:00)
- 31-dec-1999 23:59:59+00:00:01 (20000101 00:00:00)
- 28-feb-1996 +1day (19960229 00:00:00) (leap year)
- 28-feb-1997 +1day (19970301 00:00:00) (nonleap year)
- 28-feb-1997 +1month (19970328 00:00:00)
- 28-feb-1997 +1month 11:59:59 (19970328 11:59:59)
- 28-feb-1997 +20years (20170228 00:00:00)
- 28-feb-1997 +8000years (99970228 00:00:00)
-
- For compatibility with VMS, the following special delta-time format is
- also accepted:
-
- +number-hh:mm:ss
- -number-hh:mm:ss
-
- (no spaces). The hyphen after the number indicates days. It
- corresponds exactly to the Kermit notation:
-
- +numberdhh:mm:ss
- -numberdhh:mm:ss
-
- The following forms all indicate exactly the same date and time:
-
- 18-Sep-2001 12:34:56 +1-3:23:01
- 18-Sep-2001 12:34:56 +1d3:23:01
- 18-Sep-2001 12:34:56 +1 day 3:23:01
-
- and mean "add a day plus 3 hours, 23 minutes, and 1 second" to the
- given date.
-
- Note that delta times are not at all the same as UTC offsets; the
- former specifies an adjustment to the given date/time and the latter
- specifies that the local time is a particular distance from Universal
- Time, for example:
-
- 11-Aug-2001 12:34:56 -0800 (20010811 16:34:56 -- UTC Offset)
- 11-Aug-2001 12:34:56 -08:00 (20010811 04:34:56 -- Delta time)
-
- If you give a time followed by a modifer that starts with a + or -
- sign, how does Kermit know whether it's a UTC offset or a delta time?
- It is treated as a UTC offset if the sign is followed by exactly four
- decimal digits; otherwise it is a delta time. Examples (for USA
- Eastern Daylight Time):
-
- 11-Aug-2001 12:34:56 -0800 (20010811 16:34:56 -- UTC Offset)
- 11-Aug-2001 12:34:56 -08:00 (20010811 04:34:56 -- Delta time)
- 11-Aug-2001 12:34:56 -800 (20010811 04:34:56 -- Delta time)
- 11-Aug-2001 12:34:56 -8 (20010811 04:34:56 -- Delta time)
-
- The first example says that at some unknown place which is 8 hours
- ahead of Universal Time, the time is 12:34:56, and this corresponds to
- 16:34:56 in Eastern Daylight time. The second example says to subtract
- 8 hours from the local time. The third and fourth are delta times
- because, even though a colon is not included, the time does not
- consist of exactly 4 digits.
-
- When a delta time is written after a timezone, however, there is no
- ambiguity and no syntax distinction is required:
-
- 11-Aug-2001 12:34:56 -0800 -0800 (20010811 08:34:56)
- 11-Aug-2001 12:34:56 -0800 -08:00 (Ditto)
- 11-Aug-2001 12:34:56 -08:00 -08:00 (Illegal)
-
- 8.13.5. The DATE Command
-
- Obviously a great many combinations of date, time, time zone, and
- delta time are possible, as well as many formatting options. The
- purpose of all this flexibility is to comply with as many standards as
- possible -- Internet RFCs, ISO standards, and proven corporate
- standards -- as well as with notations commonly used by real people,
- in order that dates and times from the widest variety of sources can
- be assigned to a variable and used in any date-time field in any
- Kermit command.
-
- You can test any date-and/or-time format with the DATE command, which
- converts it to standard yyyymmdd hh:mm:ss format if it is understood,
- or else gives an explicit error message (rather than just "BAD DATE"
- as in previous C-Kermit releases) to indicate what is wrong with it.
- Examples (on Tuesday, 31 July 2001 in New York City, Eastern Daylight
- Time, UTC -0400):

- 8.13.6. New Date-Time Functions
-
- In the following descriptions, date-time function arguments are the
- same free-format date-time strings discussed above, with the same
- defaults for missing fields. They are automatically converted to
- standard format internally prior to processing.
-
- \fcvtdate(d1)
- Converts the date-time d1 to standard format and local time.
- This function is not new, but now it accepts a wider range of
- argument formats that can include timezones and/or delta times.
- If the first argument is omitted, the current date and time are
- assumed. The optional second argument is a format code for the
- result:
-
- n1 = 1: yyyy-mmm-dd hh:mm:ss (mmm = English 3-letter month
- abbreviation)
- n1 = 2: dd-mmm-yyyy hh:mm:ss (ditto)
- n1 = 3: yyyymmddhhmmss (all numeric)
-
- \futcdate(d1)
- Converts the date-time d1 to Universal Coordinated Time (UTC),
- also known as GMT or Zulu or Zero-Meridian time. The default d1
- is NOW. If d1 is a valid date-time, the UTC result is returned
- in standard format, yyyymmdd hh:ss:mm.
-
- \fcmpdates(d1,d2)
- Compares two free-format date-times, d1 and d2, and, if both
- arguments are valid, returns a number: -1 if d1 is earlier than
- (before) d2; 0 if d1 is the same as d2; 1 if d1 is later than
- (after) d2.
-
- \fdiffdates(d1,d2)
- Computes the difference between two free-format date-times, d1
- and d2. If both arguments are valid, returns a delta time which
- is negative if d1 is earlier than (before) d2 and positive
- otherwise. If d1 and d2 are equal, the result is "+0:00".
- Otherwise, the result consists of the number of days, hours,
- minutes, and seconds that separate the two date-times. If the
- number of days is zero, it is omitted. If the number of days is
- nonzero but the hours, minutes, and seconds are all zero, the
- time is omitted. if the seconds are zero, they are omitted.
-
- \fdelta2secs(dt)
- Converts a delta time to seconds. For example, "+1d00:00:01" to
- 86401. Valid delta times must start with a + or - sign. Days
- are accepted as time units, but not years, months, or weeks. If
- the result would overflow a computer long word (as would happen
- with 32-bit long words when the number of days is greater than
- 24854), the function fails.
-
- HINT: Although Kermit has a number of built-in date and time
- variables, it doesn't have a single one suitable for writing a
- timestamp. For this you would normally use something like "\v(ndate)
- \v(time)". But \fcvtdate() (with no arguments) is equivalent: it
- returns the current date and time in yyyymmdd hh:mm:ss format,
- suitable for time stamping.
-
- 8.13.7. Date-Time Programming Examples
-
- Here's a macro that converts any date-time to UTC, which you might use
- if C-Kermit didn't already have a \futcdate() function:
-
- define utcdate {
- .local := \fcvtdate(\%*) ; 1.
- .tmp := \fcvtdate(\m(local)UTC) ; 2.
- .offset := \fdiffdate(\m(local),\m(tmp)) ; 3.
- .utc := \fcvtdate(\m(local)\m(offset)) ; 4.
- sho mac utc ; 5.
- }
-
- Brief explanation: Line 1 converts the macro argument, a free-format
- date-time, to standard-format local time. Line 2 appends the "UTC"
- timezone to the local time and converts the result to local time. In
- other words, we take the same time as the local time, but pretend it's
- UTC time, and convert it to local time. For example, if New York time
- is 4 hours ahead of UTC, then 6:00pm New York time is 2:00pm UTC. Line
- 3 gets the difference of the two results (e.g. "+04:00"). Line 4
- appends the difference (delta time) to the local time, and converts it
- again, which adds (or subtracts) the UTC offset to the given time.
- Line 5 displays the result.
-
- Here's a script that opens a web page, gets its headers into an array,
- scans the array for the "Last-Modified:" header, and inteprets it:
- http open www.columbia.edu
- if fail stop 1 HTTP OPEN failed
- http /array:a head index.html /dev/null
- if fail stop 1 HTTP GET failed
- show array a
- for \%i 1 \fdim(&a) 1 {
- .\%x := \findex(:,\&a[\%i])
- if not \%x continue
- .tag := \fleft(\&a[\%i],\%x-1)
- .val := \fltrim(\fsubstr(\&a[\%i],\%x+1))
- if ( eq "\m(tag)" "Last-Modified" ) {
- echo HTTP Date: \m(val)
- .rdate := \fcvtdate(\m(val))
- echo {Standard Date (local): \m(rdate)}
- echo {Standard Date (UTC): \futcdate(\m(rdate))}
- break
- }
- }
- http close
-
- The result:
-
- HTTP Date: Mon, 13 Aug 2001 20:05:42 GMT
- Standard Date (local): 20010813 16:05:42
- Standard Date (UTC): 20010813 20:05:42
-
- As you can see, Kermit had no trouble decoding the date-time-string
- from the website, converting to local time, and converting back to UTC
- with no conflicts or loss of information. If it had been in any other
- known format, the result would have been the same.
-
- Now suppose we want to download the web page only if it is newer than
- our local copy. The \fdate(filename) function (which returns the
- modification date-time of the given file) and the new \fcmpdates()
- function make it easy. Insert the following just before the BREAK
- statement:
-
- if ( < 0 \fcmpdates(\m(rdate),\fdate(index.html)) ) {
- echo GETTING index.html...
- http get index.html index.html
- if success echo HTTP GET OK
- } else {
- echo index.html: no update needed
- }
- http close
- exit
-
- This says, "if 0 is less than the comparison of the remote file date
- and the local file date, get the remote file, otherwise skip it." And
- it automatically reconciles the time-zone difference (if any).
-
- It would be nice to be able to extend this script into a
- general-purpose website updater, but unfortunately HTTP protocol
- doesn't provide any mechanism for the client to ask the server for a
- list of files, recursive or otherwise.

- 8.14. Trapping Keyboard Interruption
-
- Normally when you type Ctrl-C and Kermit is in command mode (as
- opposed to CONNECT mode) with COMMAND INTERRUPTION ON (as it is unless
- you have set it OFF), Kermit interrupts any command that is currently
- in progress, and if a command file or macro is executing, rolls the
- command stack back to top level, closing all open command files,
- deactivating all macros, deallocating all local variables and arrays,
- and leaving you at the command prompt.
-
- Suppose, however, you want certain actions to occur when a script is
- interrupted; for example, closing open files, writing log entries, or
- displaying summary results. You can do this by defining a macro named
- ON_CTRLC. When Ctrl-C is detected, and a macro with this name is
- defined, Kermit executes it from the current command level, thus
- giving it full access to the environment in which the interruption
- occurred, including local variables and open files. Only when the
- ON_CTRLC macro completes execution is the command stack rolled back to
- top level.
-
- Once the ON_CTRLC macro is defined, it can be executed only once. This
- is to prevent recursion if the user types Ctrl-C while the ON_CTRLC
- macro is executing. If you type Ctrl-C while the Ctrl-C macro is
- active, this does not start a new copy of ON_CTRLC; rather, it returns
- to the top-level command prompt. After the ON_CTRLC macro returns, it
- has been removed from the macro table so if you want to use it again
- or install a different Ctrl-C trap, you must execute a new DEFINE
- ON_CTRLC command. In any case, as always when you interrupt a script
- with Ctrl-C, its completion status is FAILURE.
-
- Normally the ON_CTRLC macro would be defined in the command file or
- macro to which it applies, and should be declared LOCAL. This way, if
- the command file or macro completes successfully without being
- interrupted, the ON_CTRLC definition disappears automatically.
- Otherwise the definition would still be valid and the macro would be
- executed, probably out of context, the next time you typed Ctrl-C.
-
- Here's a simple example of a command file that sets a Ctrl-C trap for
- itself:
-
- local on_ctrlc ; Make Ctrl-C trap local to this command file.
- define on_ctrlc { ; Define the ON_CTRLC macro.
- echo Interrupted at \v(time).
- echo Iterations: \%n
- }
- xecho Type Ctrl-C to quit
- for \%n 1 999 1 { ; Prints a dot every second until interrupted.
- sleep 1
- xecho .
- }
- echo Finished normally at \v(time) ; Get here only if not interrupted.
- decrement \%n
- echo Iterations: \%n
-
- This prints a summary no matter whether it completes normally or is
- interrupted from the keyboard. In both cases the trap is automatically
- removed afterwards.
-
- For an example of how to use ON_CTRLC to debug scripts, see
- [476]Section 8.1.

-9. S-EXPRESSIONS
-
- This section is primarily for those who want to write
- calculation-intensive scripts, especially if they require
- floating-point arithmetic, and/or for those who are familiar with the
- LISP programming language.
-
- Ever since C-Kermit version 5 was released in 1988, scripting has been
- one of its major attractions, and arithmetic is a key part of it.
- Versions 5 and 6 included integer arithmetic only, using traditional
- algebraic notation, e.g.:
-
- echo \fevaluate(3*(2+7)/2)
- 13
-
- C-Kermit 7.0 added support for floating-point arithmetic, but only
- through function calls:
-
- echo \ffpdivide(\ffpmultiply(3.0,\ffpadd(2.0,7.0)),2.0)
- 13.5
-
- C-Kermit 8.0 introduces a third form of arithmetic that treats
- integers and floating-point numbers uniformly, is easier to read and
- write, and executes very quickly:
-
- (/ (* 3 (+ 2 7)) 2)
- 13.5
-
- But first some background.
-
- The Kermit command and scripting language differs from true
- programming languages (such as C or Fortran) in many ways; one of the
- most prominent differences is the way in which variables are
- distinguished from constants. In a command language, words are taken
- literally; for example, the Unix shell:
-
- cat foo.bar
-
- displays the file named foo.bar. Whereas in a programming language
- like C, words are assumed to be variables:
-
- s = foo.bar; /* Assigns the value of foo.bar to the variable s */
-
- To make a programming language take words literally, you have to quote
- or "escape" them:
-
- s = "foo.bar"; /* Assigns a pointer to the string "foo.bar" to the variable
-s */
-
- The opposite holds for command languages: to get them to treat a word
- as a variable rather than a constant, you have to escape them. For
- example, in the Unix shell:
-
- foo=123 ; Assign value 123 to variable foo.
- echo foo ; Prints "foo"
- echo $foo ; Prints "123"
-
- And in Kermit:
-
- define foo 123 ; Assign value 123 to variable foo.
- echo 123 ; This prints "123".
- echo foo ; This prints "foo".
- echo \m(foo) ; This prints "123".
-
- In other words, character strings (such as "foo" above) are
- interpreted as literal strings, rather than variable names, except in
- special commands like DEFINE that deal specifically with variable
- names (or in numeric contexts as explained in [481]Section 8.2). The
- special "escape" character (dollar sign ($) for the shell, backslash
- (\) for Kermit) indicates that a variable is to be replaced by its
- value.
-
- The requirement to escape variable names in command languages normally
- does not impose any special hardship, but can add a considerable
- notational burden to arithmetic expressions, which are typically full
- of variables. Especially in Kermit when floating point numbers are
- involved, where you must use special \ffpxxx() functions, e.g.
- "\ffpadd(\m(a),\m(b))" rather than the simple "+" operator to add two
- floating-point numbers together, because the original arithmetic
- handler doesn't support floating point (this might change in the
- future). To illustrate, the general formula for the area of a triangle
- is:
-
- sqrt(s * (s - a) * (s - b) * (s - c))
-
- where a, b, and c are the lengths of the triangle's three sides and:
-
- s = (a + b + c) / 2
-
- Except in special cases (e.g. a = 3, b = 4, c = 5), the result has a
- fractional part so the computation must be done using floating-point
- arithmetic. We can create a Kermit 7.0 function for this as follows:
-
- def area {
- local s t1 t2 t3
- assign s \ffpdiv(\ffpadd(\ffpadd(\%1,\%2),\%3),2.0)
- assign t1 \ffpsub(\m(s),\%1)
- assign t2 \ffpsub(\m(s),\%2)
- assign t3 \ffpsub(\m(s),\%3)
- return \ffpsqrt(\ffpmul(\m(s),\ffpmul(\m(t1),\ffpmul(\m(t2),\m(t3)))))
- }
-
- But as you can see, this is rather cumbersome. Note, in particular,
- that arithmetic functions like \ffpadd(), \ffpmul(), etc, take exactly
- two operands (like their symbolic counterparts + and *), so obtaining
- the product of three or more numbers (as we do in this case) is
- awkward.
-
- Using the alternative S-Expression notation, we can reduce this to a
- form that is both easier to read and executes faster (the details are
- explained later):
-
- def newarea {
- (let s (/ (+ \%1 \%2 \%3) 2.0))
- (sqrt (* s (- s \%1) (- s \%2) (- s \%3)))
- }
-
- In both examples, the \%1..3 variables are the normal Kermit macro
- arguments, referenced by the normal escaping mechanism. For increased
- readability, we can also assign the macro arguments \%1, \%2, and \%3
- to the letters a, b, and c corresponding to our formula:
-
-def newarea {
- (let a \%1 b \%2 c \%3)
- (let s (/ (+ a b c) 2.0))
- (sqrt (* s (- s a) (- s b) (- s c)))
-}
-
- And now the Kermit function reads almost like the original formula.
- Here Kermit behaves more like a regular programming language. In an
- S-Expression, macro names need not be escaped when they are used as
- the names of numeric variables.

-
- 9.1. What is an S-Expression?
-
- The S-Expression concept is borrowed from the Lisp programming
- language. "S-Expression" is short for Symbolic Expression (itself
- sometimes shortened to SEXP). S-Expressions provide a kind of
- Alternative Mini-Universe within the Kermit command language when the
- regular rules don't apply, a universe enclosed in parentheses.
-
- C-Kermit does not pretend to be a full Lisp interpreter; only the
- arithmetic parts of Lisp have been incorporated: S-Expressions that
- operate on numbers and return numeric values (plus extensibility
- features described in [486]Section 9.8, which allow some degree of
- string processing).
-
- An S-Expression is a list of zero or more items, separated by spaces,
- within parentheses. Examples:
-
- ()
- (1)
- (a)
- (+ a 1)
- (* 2 a b)
-
- If the S-Expression is empty, it has the NIL (empty) value. If it is
- not empty and the first item is an operator (such as + or *), there
- can be zero or more subsequent items, called the operands:
-
- (+ 1 2)
-
- Here the operator is "+" and the operands are "1" and "2", and the
- value of the S-Expression is the value of the operation (in this case
- 3). The operator always comes first, which is different from the
- familiar algebraic notation; this because S-Expression operators can
- have different numbers of operands:
-
- (+ 1)
- (+ 1 2)
- (+ 1 2 3 4 5 6 7 8 9)
-
- If the first item in the S-Expression is not an operator, then it must
- be a variable or a number (or a macro; see [487]Section 9.8), and the
- S-Expression can only contain one item; in this case, the
- S-Expression's value is the value of the variable or number:
-
- (a)
- (3)
-
- Operands can be numbers, variables that have numeric values, functions
- that return numbers, or other S-Expressions. To illustrate an
- S-Expression within an S-Expression, observe that:
-
- (+ 1 2)
-
- is equivalent to any of the following (plus an infinite number of
- others):
-
- (+ 1 (+ 1 1))
- (+ (- 3 2) (/ 14 (+ 3 4)))
-
- S-Expressions can be nested to any reasonable level; for example, the
- value of the following S-Expression is 64:
-
- (- (* (+ 2 (* 3 4)) (- 9 (* 2 2))) 6)
-
- Operators have no precedence, implied or otherwise, since they can't
- be mixed. The only exceptions are unary + and -, which simply indicate
- the sign of a number:
-
- (* 3 -1)
-
- Order of evaluation is specified entirely by parentheses, which are
- required around each operator and its operands: (+ a (* b c)) instead
- of (a + b * c).
-
- S-Expressions provide a simple and isolated environment in which
- Kermit's macro names can be used without the \m(...) escaping that is
- normally required. Given:
-
- define a 1
- define b 2
- define c 3
-
- Then:
-
- (+ \m(a) \m(b) \m(c))
-
- is equivalent to:
-
- (+ a b c)
-
- Within an S-Expression, as in other strictly numeric contexts
- ([488]Section 8.2), any operand that starts with a letter is treated
- as a Kermit macro name. In this context, abbreviations are not
- accepted; variable names must be spelled out in full. Alphabetic case
- is not significant; "a" and "A" are the same variable, but both are
- different from "area".
-
- Of course, regular Kermit variables and functions can be used in
- S-Expressions in the normal ways:
-
- (* \v(math_pi) (^ \%r 2)) ; Area of a circle with radius \%r
- (+ \fjoin(&a)) ; Sum of all elements of array \&a[]
-

- Home ]
- _________________________________________________________________
-
- 9.2. Integer and Floating-Point-Arithmetic
-
- Normally, if all numbers in an S-Expression are integers, the result
- is an integer:
-
- (+ 1 1) ; Result is 2
- (/ 9 3) ; Result is 3
-
- If any of the operands is floating point, however, the result is also
- floating point:
-
- (+ 1 1.0) ; Result is 2.0
- (/ 9.0 3) ; Result is 3.0
-
- If all the operands are integers but the result has a fractional part,
- the result is floating point:
-
- (/ 10 3) ; Result is 3.333333333333333
-
- To force an integer result in such cases, use the TRUNCATE operator:
-
- (truncate (/ 10 3)) ; Result is 3
-
- Similarly, to force a computation to occur in floating point, you can
- coerce one of its operands to FLOAT:
-
- (+ 1 (float 1)) ; Result is 2.0
-
- The result is also floating point if the magnitude of any integer
- operand, intermediate result, or the result itself, is larger than the
- maximum for the underlying machine architecture:
-
- (^ 100 100)
-
- If the result is too large even for floating-point representation,
- "Infinity" is printed; if it is too small to be distinguished from 0,
- 0.0 is returned.
-
- Large numbers can be used and large results generated, but they are
- accurate only to the precision of the underlying machine. For example,
- the result of:
-
- (+ 111111111111111111111 222222222222222222222)
-
- should be 333333333333333333333, but 333333333333333300000.0 is
- produced instead if the machine is accurate to only about 16 decimal
- digits, even with coercion to floating-point. The order of magnitude
- is correct but the least significant digits are wrong. The imprecise
- nature of the result is indicated by the ".0" at the end. Contrast
- with:
-
- (+ 111111111 222222222)
-
- which produces an exact integer result.

- _________________________________________________________________
-
- 9.3. How to Use S-Expressions
-
- S-Expressions may be given as commands to C-Kermit. Any command whose
- first character is "(" (left parenthesis) is interpreted as an
- S-Expression.
-
- If you enter an S-Expression at the C-Kermit> prompt, its result is
- printed:
-
- C-Kermit>(/ 10.0 3)
- 3.333333333333333
- C-Kermit>
-
- If an S-Expression is executed within a macro or command file, its
- value is not printed. However, you can control the printing action
- with:
-
- SET SEXPRESSION ECHO { AUTO, ON, OFF }
- AUTO is the default, meaning print the value at top level only;
- ON means always print the value; OFF means never print it.
-
- In any case, the value of the most recent S-Expression (and the
- S-Expression itself) may be accessed programmatically through the
- following variables:
-
- \v(sexpression)
- The S-Expression most recently executed.
-
- \v(svalue)
- The value of the S-Expression most recently executed.
-
- Besides issuing S-Expressions as commands in themselves, you can also
- execute them anywhere within a Kermit command, but in this case they
- must be enclosed in a function call (otherwise they are taken
- literally):
-
- \fsexpression(s)
- The argument "s" is an S-Expression; the outer parentheses may
- be omitted. The value of the S-Expression is returned. Note
- that since S-Expressions usually contain spaces, some form of
- grouping or quoting might be needed in some contexts:
-
- echo \fsexpression((+ 1 1)) ; Outer parentheses may be included
- echo \fsexpr(+ 1 1) ; Outer parentheses may be omitted
- echo Value = "\fsexp(+ 1 a)" ; Can be embedded in strings
- echo Value = \&a[\fsexp(/ b 2)] ; Can be used in array subscripts
- if = {\fsexp(+ 1 1)} 2 { ; Braces needed here for grouping
- echo One plus one still equals two
- }
-
- The IF statement illustrates how to use S-Expressions as (or in) IF or
- WHILE conditions:
-
- * Although S-Expressions and IF conditions are similar in
- appearance, they are not interchangeable. Therefore you must use
- \fsexpr() to let Kermit know it's an S-Expression rather than a
- regular IF condition, or a boolean or algebraic expression within
- an IF condition.
- * In contexts where a single "word" is expected, you must enclose
- the \fsexp() invocation in braces if the S-Expression contains
- spaces (and most of them do).
-
- If an S-Expression is the last command executed in a macro, its value
- becomes the return value of the macro; no RETURN command is needed.
- Example:
-
- def newarea {
- (let s (/ (+ \%1 \%2 \%3) 2.0))
- (sqrt (* s (- s \%1) (- s \%2) (- s \%3)))
- }
-
- This is equivalent to (but more efficient than):
-
- def newarea {
- (let s (/ (+ \%1 \%2 \%3) 2.0))
- return \fsexp(sqrt (* s (- s \%1) (- s \%2) (- s \%3)))
- }
-
- When an S-Expression is entered as a command -- that is, the first
- nonblank character of the command is a left parenthesis -- then it is
- allowed to span multiple lines, as many as you like, until the first
- left parenthesis is matched:
-
- (let s (/
- (+
- \%1
- \%2
- \%3
- )
- 2.0
- )
- )
- (sqrt (*
- s
- (- s \%1)
- (- s \%2)
- (- s \%3)
- )
- )
-
- The S-Expression concept lends itself easily to embedding and
- recursion, but the depth to which recursion can occur is limited by
- the resources of the computer (memory size, address space, swap space
- on disk) and other factors. There is no way that C-Kermit can know
- what this limit is, since it varies not only from computer to
- computer, but also from moment to moment. If resources are exhausted
- by recursion, C-Kermit simply crashes; there's no way to trap this
- error. However, you can set a depth limit on S-Expressions:
-
- SET SEXPRESSION DEPTH-LIMIT number
- Limits the number of times the S-Expression reader can invoke
- itself without returning to the given number. The default limit
- is 1000. This limit applies to S-Expressions embedded within
- other S-Expressions as well as to S-Expressions that invoke
- recursive macros. If the limit is exceeded, Kermit prints
- "?S-Expression depth limit exceeded" and returns to its prompt.
- More about recursion in [497]Section 9.8.
-
- You can also test the depth programmatically:
-
- \v(sdepth)
- The current S-Expression invocation depth. The depth includes
- both nesting level and recursion. For example, in:
- (foo (foo (foo (foo (foo))))), the innermost (foo) is at depth
- 5.
-
- Help, completion, and syntax checking are not available within an
- S-Expression. If you type ? within an S-Expression, it says:
-
- C-Kermit>(? S-Expression ("help sexp" for details)
-
- As it says, typing "help sexp" will display a brief help text.
-
- The SHOW SEXPRESSION command displays current SET SEXPRESSION settings
- and related information.

-
- 9.4. Summary of Built-in Constants and Operators
-
- Three constants are built in:
-
- * PI, whose value is the value of pi (the quotient of circumference
- of any circle and its diameter, 3.141592653...) to the underlying
- machine's precision;
- * T, which always has the value 1, which signifies truth in Kermit
- logical expressions or S-Expressions;
- * NIL, which always has the empty value, and can serve as a False
- truth value.
-
- These constants are specific to S-Expressions and are not visible
- outside them. They may not be used as the target of an assignment. So,
- for example:
-
- (setq t 0) Fails
- assign t 0 Succeeds but this is not the same T!
-
- E (the base of natural logarithms, 2.7182818184...) is not built in
- since it is not intrinsic in most Lisp dialects. If you want E to be
- the base of natural logarithms you can:
-
- (setq e (exp 1))
-
- Operators are either symbols (such as "+") or words. Words must be
- spelled out in full, not abbreviated. Differences of alphabetic case
- are ignored.
-
- The most basic operation in S-Expressions is evaluation:
-
- EVAL [ s-expression or variable or number [ another [ another ... ] ]
- ]
- Evaluates its operands and returns the value of the last one
- evaluated. Examples:
-
- (eval) 0
- (eval 1) 1
- (eval a) value of a
- (eval (+ 1 a)) value of a+1
- (eval (setq a 1) (setq b (+ a 0.5))) value of b (= a+0.5)
-
- You can use "." as a shorthand for EVAL:
-
- (.)
- (. 1)
- (. a)
- (. (+ 1 a))
- (. (setq a 1) (setq b (+ a 0.5)))
-
- Opposite of EVAL is the operator that suppresses evaluation of its
- operand:
-
- QUOTE item
- The value (quote item) is "item". If the item is itself an
- S-Expression, the result is the S-Expression with the outer
- parentheses stripped. Examples:
-
- (quote) (illegal)
- (quote a) a
- (quote hello) hello
- (quote (this is a string)) this is a string
- (quote this is a string) (illegal)
-
- A shorthand notation is also accepted for quoting:
- 'a is equivalent to (quote a). And therefore:
- '(a b c) is equivalent to (quote (a b c)).
- More about quoting in [502]Section 9.8.
-
- STRING item
- Is a combination of EVAL and QUOTE. It evaluates the item as an
- S-Expression, and then puts quotes around the result (more
- about this in [503]Section 9.8).
-
- The following operators assign values to variables:
-
- SETQ [ variable [ value [ variable [ value [ ... ] ] ] ] ]
- Applies to global variables. For each variable given: if a
- value is not given, the variable is undefined. If a value is
- given, assigns the value to the variable. The value may be a
- number, a variable, or anything that resolves to a number
- including an S-Expression. Returns the value of the last
- assignment. Examples:
-
- (setq) Does nothing, returns NIL.
- (setq a) Undefines a, returns NIL.
- (setq a 1) Assigns 1 to a, returns 1.
- (setq a 1 b 2) Assigns 1 to a, 2 to b, returns 2.
- (setq a 1 b 2 c) Assigns 1 to a, 2 to b, undefines c, returns NIL.
-
- To undefine a variable that is not the final one in the list, give it
- a value of "()" or NIL:
-
- (setq a () b 2) Undefines a, assigns 2 to b, returns 2.
- (setq a nil b 2) Ditto.
-
- Note that a variable can be used right away once it has a value:
-
- (setq a 1 b a) Assigns 1 to a, the value of a (1) to b, returns 1.
-
- The results of SETQ (when used with macro names) can be checked
- conveniently with SHOW MACRO, e.g:
-
- show mac a b c
-
- LET [ variable [ value [ variable [ value [ ... ] ] ] ] ]
- Like SETQ, but applies to local variables. Note that "local" is
- used in the Kermit sense, not the Lisp sense; it applies to the
- current Kermit command level, not to the current S-Expression.
-
- If you want to use SETQ or LET to assign a value to a backslash
- variable such as \%a or \&a[2], you must double the backslash:
-
- (setq \\%a 3)
- (setq \\%b (+ \%a 1))
- (setq \\&a[2] (setq (\\%c (+ \%a \%b))))
-
- In other words:
-
- * Double the backslash when you want to indicate the variable's
- NAME;
- * Don't double the backslash when you want its VALUE.
-
- See [504]Section 9.6 for a fuller explanation of variable syntax and
- scope.
-
- Here's a summary table of arithmetic operators; in the examples, a is
- 2 and b is -1.3:
-
- Operator Description Example Result
- + Adds all operands (0 or more) (+ a b) 0.7
- - Subtracts all operands (0 or more) (- 9 5 2 1) 1
- * Multiplies all operands (0 or more) (* a (+ b 1) 3) -1.80
- / Divides all operands (2 or more) (/ b a 2) -0.325
- ^ Raise given number to given power (^ 3 2) 9
- ++ Increments variables (++ a 1.2) 3.2
- -- Decrements variables (-- a) 1
- ABS Absolute value of 1 operand (abs (* a b 3)) 7.8
- MAX Maximum of all operands (1 or more) (max 1 2 3 4) 4
- MIN Minimum of all operands (1 or more) (min 1 2 3 4) 1
- MOD (%) Modulus of all operands (1 or more) (mod 7 4 2) 1
- FLOAT Convert an integer to floating-point (float 1) 1.0
- TRUNCATE Integer part of floating-point operand (truncate 3.333) 3
- CEILING Ceiling of floating-point operand (ceiling 1.25) 2
- FLOOR Floor of floating-point operand (floor 1.25) 1
- ROUND Operand rounded to nearest integer (round 1.75) 2
- SQRT Square root of 1 operand (sqrt 2) 1.414..
- EXP e (2.71828..) to the given power (exp -1) 0.367..
- SIN Sine of angle-in-radians (sin (/ pi 2)) 1.0
- COS Cosine of angle-in-radians (cos pi) -1.0
- TAN Tangent of angle-in-radians (tan pi) 0.0
- LOG Natural log (base e) of given number (log 2.7183) 1.000..
- LOG10 Log base 10 of given number (log10 1000) 3.0
-
- The ++ and -- operators are also assignment operators and work just
- like SETQ and LET in their interpretations of operators and operands,
- but:
-
- * Each target variable must already be defined and have a numeric
- value;
- * The assignment value is the amount by which to increment or
- decrement the variable.
- * If an assignment value is not given, 1 is used.
-
- If you include more than one variable-value pair in a ++ or --
- expression, every variable (except, optionally, the last) must be
- followed by a value. Examples:
-
- (++ a) Equivalent to (setq a (+ a 1)) and to (++ a 1)
- (++ a 2) Equivalent to (setq a (+ a 2))
- (-- a (* 2 pi)) Equivalent to (setq a (- a (* 2 pi)))
- (++ a 1 b 1 c 1 d) Equivalent to four SETQs incrementing a,b,c,d by 1.
-
- Another group of operators forms the predicates. These return a "truth
- value", in which 0 (or NIL) is false, and 1 or any other nonzero
- number is true.
-
- Operator Description Example Result
- = (or ==) Operands are equal (= 1 1.0) 1
- != Operands are not equal (!= 1 1.0) 0
- < Operands in strictly ascending order (< 1 2 3) 1
- <= Operands in ascending order (<= 1 1 2 3) 1
- > Operands in strictly descending order (> 3 2 1) 1
- >= Operands in descending order (<= 3 3 2 1) 1
- AND (&&) Operands are all true (and 1 1 1 1 0) 0
- OR (||) At least one operand is true (or 1 1 1 1 0) 1
- XOR Logical Exclusive OR (xor 3 1) 0
- NOT (!) Reverses truth value of operand (not 3) 0
-
- The Exclusive OR of two values is true if one value is true and the
- other value is false.
-
- And another group operates on bits within an integer word:
-
- Operator Description Example Result
- & Bitwise AND (& 7 2) 2
- | Bitwise OR (| 1 2 3 4) 7
- # Bitwise Exclusive OR (# 3 1) 2
- ~ Reverses all bits (~ 3) -4
-
- These operators coerce their operands to integer by truncation if
- necessary. The result of bit reversal is hardware dependent.
-
- The final category of operator works on truth values:
-
- Operator Description Example Result
- IF Conditional evaluation (if (1) 2 3) 2
-
- IF (predicate) (s1) [ (s2) ]
- The IF operator is similar to Kermit's IF command. If the
- predicate is true (i.e. evaluates to a nonzero number), the
- first S-Expression (s1) is evaluated and its value is returned.
- Otherwise, if (s2) is given, it is evaluated and its value
- returned; if (s2) is not given, nothing happens and the NIL
- (empty) value is returned.
-
- You can group multiple expressions in the s1 and s2 expressions using
- EVAL (or "."):
-
- (if (< a 0) (eval (setq x 0) (setq y 0)) (eval (setq x a) (setq y b)))
-
- or equivalently:
-
- (if (< a 0) (. (setq x 0) (setq y 0)) (. (setq x a) (setq y b)))
-
- Each operator has its own requirement as to number and type of
- operands. In the following table, "number" means any kind of number --
- integer or floating-point -- or a variable, function, macro, or
- S-Expression that returns a number; "vname" means variable name,
- "fpnumber" means a floating-point number (or anything that resolves to
- one), and "integer" means integer (or anything that resolves to one).
- "truthvalue" means anything that resolves to a value of zero or an
- empty value (which indicates false) or a nonzero value (which
- indicates true). "any" means any kind of value, including none at all.
-
- Operator Number of operands Type of operands Returns
- EVAL (.) 0 or more S-Expression Last value (default NIL)
- STRING 1 S-Expression string
- QUOTE (') 1 word string
- SETQ 0 or more vname value pairs Last value (default NIL)
- LET 0 or more vname value pairs Last value (default NIL)
- + 0 or more number number (default 0)
- - 0 or more number number (default 0)
- * 0 or more number number (see note (1))
- / 2 or more number number
- ^ 2 or more number number

-
- Operators that don't require any arguments return the default values
- shown.
-
- 1. The value of "*", when used as an operator, is initially "1" and
- the value of the most recent S-Expression thereafter, as in Franz
- Lisp. This is handy when doing a series of calculations by hand:

- 5308.968
- C-Kermit>(/ * 2)
- 2654.4840

- 2. The bitwise operators coerce their operands to integer by
- truncation.

- 9.5. Variables
-
- As noted elsewhere in this discussion, all backslash items (variables
- such as \%a, macro parameters such as \%1, array elements such as
- \&a[\%i], built-in variables such as \v(ndate), built-in functions
- such as \fjoin(), macro names enclosed in \m(), \s(), or \:(), etc)
- are evaluated at "top level" before the S-Expression is sent to the
- S-Expression reader. To use a backslash variable as the target of an
- assignment (e.g. by SETQ, LET, ++, or --), you must double the
- backslash, e.g. (setq \\%r 1234). This is discussed at greater length
- in the next section.
-
- Thus S-Expression reader generally deals only with macro names (not
- backslash items) as variables. It is important to understand how the
- reader handles macro names. There are fundamentally two kinds of
- S-Expressions: those that contain a single element, such as:
-
- (foo)
-
- and those that contain more than one element:
-
- (foo a b c)
-
- If an S-Expression contains only one element, and it is the name of a
- macro, the macro's definition is examined. If the definition is a
- number (integer or floating-point, positive or negative), then this
- becomes the value of the expression. If the definition starts with '
- (apostrophe), then the quoted word or string is the value of the
- expression (explained in [509]Section 9.8). Otherwise, the macro is
- assumed to be composed of Kermit commands (possibly including
- S-Expressions), which are executed. If the macro has a RETURN value,
- or it executes an S-Expression as its last command, the result becomes
- the value of the S-Expression; otherwise the result is empty.
-
- For S-Expressions that contain more than one element, and the first
- element is the name of a macro, then this macro is executed with the
- arguments that are given, after the arguments are evaluated by the
- S-Expression reader. Likewise, If the first element is a built-in
- operator, then it is applied to the operands after they are evaluated.
- In both cases, each operand is fed to the S-Expression reader
- recursively for evaluation. If an operand is a number or a quoted
- string, it is used as-is. But if it's a macro name, this degenerates
- into the first case, and the previous paragraph applies.
-
- Examples:
-
- define foo 123
- (foo) Result: 123
- define foo 'abc
- (foo) Result: abc
- define foo '(one two three)
- (foo) Result: one two three
- define foo return \frandom(1000)
- (foo) Result: 713 (or other number)
- define foo (+ a b)
- (foo) Result: The sum of a and b
-
- A more difficult example:
-
- define foo abc
- (foo) Result: ???
-
- The result in the last example depends on the definition of abc:
-
- * If it has no definition, an error occurs; otherwise:
- * If the definition is an S-Expression, the result is the
- S-Expression's value; otherwise:
- * If the definition consists of Kermit commands, they are executed.
- But in this case "(foo)" produces the empty result, because it
- doesn't RETURN anything.
-
- The use of macros as S-Expression operators is described in
- [510]Section 9.8.

- _________________________________________________________________
-
- 9.6. Assignments and Scope
-
- The assignment operators SETQ and LET apply to global and local
- variables, respectively. SETQ and LET are standard Lisp operators
- adapted to Kermit scoping rules. When the operands are numeric or
- arithmetic, SETQ is equivalent to Kermit's EVALUATE command:
-
- (setq a (+ 1 2))
- evaluate a 1 + 2
-
- When the operand is a string, SETQ is equivalent to DEFINE:
-
- (setq a '(this is a string))
- define a this is a string
-
- In the first case, both statements create a macro named "a" with a
- value of 3. But in neither case is the macro "a" necessarily global.
- If either of these commands executes in an environment (i.e. macro
- invocation level) where a "local a" command has been given, the "a"
- macro is global to that environment, but is not visible outside it.
-
- LET is equivalent to the Kermit LOCAL command, followed by the
- corresponding EVALUATE:
-
- (let a (+ 1 2))
-
- is equivalent to:
-
- local a
- evaluate a 1 + 2
-
- Again, "local" in this context applies to the Kermit macro invocation
- stack, not to the S-Expression nesting level. To illustrate, recall
- our "newarea" macro:
-
-def newarea {
- (let a \%1 b \%2 c \%3)
- (let s (/ (+ a b c) 2.0))
- (sqrt (* s (- s a) (- s b) (- s c)))
-}
-
- Because SETQ and LET expressions return a value, they can be placed
- within a larger S-Expression. In this case we can replace the first
- reference to the "s" variable by its defining expression:
-
-def newarea {
- (let a \%1 b \%2 c \%3)
- (sqrt (* (let s (/ (+ a b c) 2.0)) (- s a) (- s b) (- s c)))
-}
-
- This would not work if LET were local to the S-Expression, but it
- works nicely in the context of Kermit macros. The previous definition
- is equivalent to:
-
-def newarea {
- local a b c s
- (setq a \%1 b \%2 c \%3)
- (sqrt (* (setq s (/ (+ a b c) 2.0)) (- s a) (- s b) (- s c)))
-}
-
- In both cases, the variables a, b, c, and s are local to the "newarea"
- macro, and global within it.
-
- Multiple assignments can be handled in several ways. Here is the
- obvious way to initialize a series of variables to the same value:
-
- (setq a 0)
- (setq b 0)
- (setq c 0)
- (setq s 0)
-
- Here is a more compact and efficient way of doing the same thing:
-
- (setq a 0 b 0 c 0 s 0)
-
- However, in case the value was more complex, it's better to put only
- one copy of it in the S-Expression; in this case we rely on the fact
- that SETQ returns the value of its last assignment:
-
- (setq a (setq b (setq c (setq s (* x (^ y 2))))))
-
- Similarly, to set a series of variables to x, x+1, x+2, ...
-
- (setq c (+ (setq b (+ (setq a (+ (setq s x) 1)) 1)) 1))
-
- In the last example, you can see why "last" does not always correspond
- to "rightmost" (the leftmost variable "c" is assigned last).
-
- If you are working with backslash variables like \%a or array elements
- like \&a[1], remember two rules:
- 1. Don't put spaces inside array brackets.
- 2. You must double the backslash when using SETQ, LET, ++, or -- to
- assign a value to a backslash variable.
-
- Examples of assigning to a backslash variable:
-
- (setq x 1)
- (setq \\%a 0)
- (setq \\&a[x+1] 1)
- (++ \\%x)
- (-- \\&a[x+2])
-
- Examples of referring to a backslash variable's value:
-
- (setq a (+ \%a 1))
- (setq b (+ \%a \&a[1]))
- (++ a \%x)
- (-- b \&a[1])
-
- The special notation is required because all backslashed items (\%x
- variables, array elements, built-in \v(xxx) variables, and \fxxx()
- function invocations) are evaluated in a single pass BEFORE the
- S-Expression is executed; any other approach would result in
- unacceptable performance. So, for example, in:
-
- declare \&a[] = 1 2 3
- define \%x 4
- define \%y 0
- (setq \\%y (+ \%x \&a[1]))
-
- the S-Expression becomes:
-
- (setq \%y (+ 4 1))
-
- before it is sent to the S-Expression evaluator. If the backslash had
- not been doubled on the assignment target, the result would have been:
-
- (setq 0 (+ 4 1))
-
- which is illegal because you can't assign a value to a number.
- Conversely, if backslashes were doubled on right-hand-side values:
-
- (setq \\%y (+ \\%x \\&a[1])
-
- this too, would give an error (not numeric - "\%x").
-
- If you omit the double backslash in the assignment target, the result
- depends on whether the variable already has a value:
-
- (setq \%a (* 3 3))
-
- If \%a has a non-numeric single-word value, then this becomes the name
- of the variable that is assigned by SETQ. To illustrate:
-
- define \%a foo
- echo \%a
- foo
- (setq \%a (* 3 3))
- echo \%a
- foo
- show macro foo
- foo = 9
-
- If \%a has no value, a numeric value, or a multiword value, an
- "invalid assignment" error occurs.

-
- 9.7. Conditional Expressions
-
- The IF operator provides a compact form of decision-making within
- S-Expressions. An IF expression can stand wherever a number might
- stand, as long is it returns a number. Here's a quick way to obtain
- the average value of all the elements in an array that contains only
- numbers:
-
- (/ (+ \fjoin(&a)) (float \fdim(&a)))
-
- This results in a "Divide by zero" error if the array is empty. If you
- want to define the average value of an empty array to be 0 instead of
- getting an error, you can use IF to check the array size:
-
- (if \fdim(&a) (/ (+ \fjoin(&a)) (float \fdim(&a))) 0)
-
- or equivalently:
-
- (if (not \fdim(&a)) 0 (/ (+ \fjoin(&a)) (float \fdim(&a))))
-
- Of course, IF can fit anywhere else into an S-Expression:
-
- (setq a (+ b (if (< c 0) 0 c)))
-
- and the IF expression can be as complex as you like:
-
- (setq a (+ b (if (and (or (> x 0) (> y 0)) (< c 0) (> d 1) (!= e 0)) 1 0)))
-
- and the "then" and "else" parts can contain multiple S-Expressions
- enclosed within (EVAL ...):
-
- (if x (eval (...) (...) (...)) (eval (...) (...) (...)))
-
- AND and OR operators are guaranteed to "short circuit". If any operand
- of AND is false, none of the subsequent operands is evaluated;
- likewise, if an OR operand is true, no further operands are evaluated.
-
- Bear in mind that the S-Expression IF is not the same as Kermit IF;
- the condition is only allowed to be an S-Expression or a variable or
- number, not the whole list of possibilities you see when you type "if
- ?" at the C-Kermit> prompt. But keep reading...

- _________________________________________________________________
-
- 9.8. Extensibility
-
- To extend the capabilities of S-Expressions, you can use Kermit macro
- names as operators, with the following limitations:
-
- * The macro must not have the same name as a built-in operator.
- * You must use the full macro name, not an abbreviation.
-
- And with the following enhancement:
-
- * If the last statement executed by the macro is an S-Expression,
- its value is returned automatically. In other words:
-
- define bump (++ \%1)
-
- is equivalent to:
-
- define bump return \fsexpression(++ \%1)
-
- Here's an example in which we define a FIBONACCI operator that returns
- the nth element, n >= 0, of the Fibonacci series, 0 1 1 2 3 5 8 13 21
- 34 55, . . ., in which the first element is 0, the second is 1, and
- each subsequent element is the sum of the two before it. This series
- was devised by Leonardo Pisano, Filius Bonacci (Fibonacci for short)
- in 1202 to describe how fast rabbits can breed, and also forms the
- basis for the Golden Mean, the branching behavior of plants, the
- spiral of a nautilus shell, etc. (Thanks to [523]Dat Thuc Nguyen for
- December 2003 corrections to this section!)
-
- We can write a FIBONACCI function as a macro easily with
- S-Expressions:
-
- define FIBONACCI {
- (if (== \%1 0) 0
- (if (== \%1 1) 1 (+ (fibonacci (- \%1 2)) (fibonacci (- \%1 1)))))
- }
-
- You can read this as:
-
- If the argument (\%1) is 0, return a result of 0; if it is 1,
- return 1; otherwise:
- return the sum of fibonacci(argument - 2) and fibonacci(argument -
- 1)
-
- Note that a RETURN statement is not needed, since S-Expressions
- automatically set the return value of their containing macros.
-
- For comparison, here's how it would be coded without S-Expressions:
-
- define FIBONACCI {
- if == \%1 0 {
- return 0
- } else if == \%1 1 {
- return 1
- } else {
- return \feval(\fexec(fibonacci \feval(\%1-2)) -
- + \fexec(fibonacci \feval(\%1-1)))
- }
- }
-
- Now we can use the FIBONACCI function (whichever way you write it)
- just as if it were a built-in operator:
-
- (fibonacci 6)
-
- Or:
-
- (setq a 10)
- (fibonacci a)
-
- Within S-Expressions only (not outside them), S-Expressions themselves
- can be used as macro arguments:
-
- (setq a 2 b 4)
- (setq x (fibonacci (* a b )))
-
- The value of the S-Expression (in this case "8"), and not the
- S-Expression itself, is sent to the macro.
-
- Your macro is responsible for argument validation and error handling.
- A robust Fibonacci macro would be more like this:
-
- define FIBONACCI {
- if < \v(argc) 2 end 1 ?\%0: Missing argument
- if > \v(argc) 2 end 1 ?\%0: Too many arguments
- if not integer \%1 end 1 ?\%0: Integers only
- if < \%1 1 end 1 ?\%0: Argument out of range
- (if (== \%1 0) 0
- (if (== \%1 1) 1 (+ (fibonacci (- \%1 2)) (fibonacci (- \%1 1)))))
- }
-
- Recall that "END nonzero-number [ message ]" causes a macro invocation
- to fail. When the macro is the operator in an S-Expression, this makes
- the S-Expression fail too. Also note that our Fibonacci macro is just
- an illustration, not a practical example. Since it is recursive (calls
- itself), it won't work for large arguments because the call stack can
- exceed available memory. See [524]Section 9.9.2 for a practical
- alternative.
-
- Kermit macros, when used as S-Expression operators, can do anything at
- all except initiate file transfers: they can print messages on the
- screen, read and write files, interact with the user, and so on. For
- example, here's a macro ASKME that asks you to enter a number, makes
- sure that you did, and then returns its value for use in the
- S-Expression:
-
- define ASKME {
- local \%n
- while true {
- ask \%n { Number: }
- if not def \%n continue
- if not numeric \%n {
- echo Not numeric - "\%n"
- continue
- }
- break
- }
- return \%n
- }
- (setq a (* 2 (askme))) ; Get number from user, double it, assign result to a.
-
- Here's a macro you can use to validate that a number is in a given
- range:
-
- define inrange {
- if != \v(argc) 4 end 1 ?\%0: Wrong number of arguments
- if ( < \%1 \%2 || > \%1 \%3 ) return 0
- return 1
- }
-
- The first argument is the number to be checked, the second is the
- minimum acceptable value, the third is the maximum. You can use this
- (for example) in IF conditions:
-
- define yes echo \%1 IS OK
- define no echo \%1 IS NOT OK
-
- (setq a -1 b 999)
- (if (inrange a 0 100) (yes a) (no a))
- (if (inrange b -1000 +1000) (yes b) (no b))
-
- This is just an illustration, of course; there's already a built-in
- operator to let you do range checking without help from macros:
-
- (if (<= 0 a 100) (yes a) (no a))
- (if (<= -1000 b +1000) (yes b) (no b))
-
- To send string parameters to a macro, some kind of quoting is required
- to tell the S-Expression parser to take a given "word" literally
- rather than replacing it by its value. For this we use the Lisp QUOTE
- operator:
-
- define length return \flength(\%1)
- (length (quote abcdefghijklmnopqrstuvwxyz))
- 26
-
- This causes the string "abcdefghijklmnopqrstuvwxyz" to be sent
- literally to the LENGTH macro. Kermit, like Lisp, also offers a
- shortcut for QUOTE, that lets us quote a word by prefixing it with a
- single quote (') character, also called apostophe (ASCII 39):
-
- (length 'abcdefghijklmnopqrstuvwxyz)
- 26
-
- The two forms are equivalent.
-
- How the macro treats its arguments is up to the macro. In the example
- above, the argument is treated as a literal string. However, it can
- also be treated as a variable name:
-
- define string This is a string
- define length return \flength(\m(\%1))
- (length 'string)
- 16
-
- Note the construct \m(\%1). This means "the value of the macro whose
- name is the value of
- \%1". The value of \%1 in this case is the word "string", and the
- value of the macro whose name is "string" is "This is a string".
-
- What if the macro takes multiple arguments, or a variable number of
- them? Here's a simple macro that prints a phrase that includes its
- arguments:
-
- define complain echo It's too \%*!
-
- (Recall that \%* means "all arguments".)
-
- It can be called in the traditional way:
-
- complain hot Result: "It's too hot!"
- complain cold and wet Result: "It's too cold and wet!"
-
- Or from an S-Expression if you quote the arguments:
-
- (complain 'hot) Result: "It's too hot!"
- (complain 'cold 'and 'wet) Result: "It's too cold and wet!"
-
- To group multiple words into a single argument, use parentheses:
-
- (complain (quote (cold and wet))) Result: "It's too cold and wet!"
- (complain '(cold and wet)) Result: "It's too cold and wet!"
-
- Note the difference:
-
- (complain 'cold 'and 'wet) Three arguments
- (complain '(cold and wet)) One argument
-
- Since the COMPLAIN macro uses \%* to refer to all its arguments, no
- matter how many, it doesn't care which form you use. But it makes a
- difference in cases where the macro refers to its arguments
- individually.
-
- To illustrate, let's consider a macro that receives the name of a
- macro and its argument list and executes it with its arguments,
- without knowing how many arguments there are. The following LOOP macro
- is used to execute the given macro with the given argument list the
- requested number of times:
-
- def loop { local i, for i 1 \%1 1 do \%2 \%3 }
-
- Within the LOOP macro, the first argument (\%1) is the loop count, \%2
- is the macro name, and \%3 is the argument list. When the LOOP macro
- is invoked traditionally like this:
-
- loop 3 complain hot
-
- it prints "It's too hot!" three times. To invoke it from an
- S-Expression, you must quote both the macro name as well as the
- argument, since in this case the macro name itself is an argument:
-
- (loop 3 'complain 'hot)
-
- Now what if you need to send different or variable numbers of
- arguments to the LOOP macro? The LOOP macro can handle it already,
- provided you group the arguments into LOOP's third argument (\%3). In
- Kermit syntax, without grouping:
-
- loop 3 complain cold and wet
-
- prints "It's too cold!" three times ("and wet" is lost); but with
- grouping (either of the following two forms):
-
- loop 3 complain {cold and wet}
- loop 3 complain "cold and wet"
-
- the LOOP macro prints "It's too cold and wet!" three times as desired.
-
- To do the same thing in an S-Expression, just use the Lisp forms of
- quoting instead of the Kermit forms; the following two are equivalent:
-
- (loop 3 'complain (quote (cold and wet)))
- (loop 3 'complain '(cold and wet))
-
- Here's a similar example in which we write a macro that shows both the
- name and the value of one or more other macros, whose names are given
- as arguments (similar to "show macro"):
-
- define display {
- local \%i
- for \%i 1 \v(argc)-1 1 {
- echo \&_[\%i] = \m(\&_[\%i])
- }
- }
-
- (Recall that \&_[] is the macro's argument vector array, equivalent to
- \%1, \%2, ...) The DISPLAY macro can be used in S-Expressions like
- this:
-
- (setq a 1 b 2 c 3)
- (display 'a 'b 'c 'd)
-
- which prints:
-
- a = 1
- b = 2
- c = 3
- d =
-
- The names must be quoted to prevent their evaluation before they are
- sent to the macro. This ability to pass variables "by name" to macros,
- rather than by value, lets you write macros that change the values of
- argument variables. For example, here's a macro that doubles the value
- of its argument variable:
-
- define double (++ \%1 \%1)
-
- which you can call like this:
-
- (setq a 12)
- (double 'a)
-
- In the macro, \%1 is replace by the variable name "a"; "(++ a a)" adds
- "a" to itself, and sets the value of "a" to the result.
-
- There are no built-in operators other than QUOTE, ', and STRING for
- handling strings in S-Expressions, but using just these, plus macros
- that use Kermit's regular string-handling features, you can easily
- extend S-Expressions to do string manipulation:
-
- define len return \flen(\%1) Returns length of argument string
- define cap return \fupper(\%1) Uppercase argument string
- define rev return \freverse(\%1) Reverses argument string
- define sub return \fsubstr(\%1,\%2,\%3) Returns substring of arg string
-
- (len '(this is a string)) Result: 16
- (rev '(this is a string)) Result: gnirts a si siht
- (rev (cap '(this is a string))) Result: GNIRTS A SI SIHT
- (sub (rev (cap '(this is a string))) 5 9) Result: TS A SI S
-
- You can assign a string to a macro name as follows:
-
- (setq foo '(this is a string))
- (setq foo (quote (this is a string)))
-
- The two are exactly equivalent. In both cases, the macro "foo" has the
- value:
-
- '(this is a string)
-
- so when it is retrieved it can be identified as a string rather than a
- number or commands to be executed. Thus:
-
- (setq foo (quote (this is a string)))
- show macro foo
- foo = '(this is a string)
- (foo)
- this is a string
-
- Note the different results for "show macro foo" and "(foo)". The
- former shows the internal definition; the latter evaluates the
- variable, which removes the quoting. And perhaps more important, note
- that if the apostrophe and surrounding parentheses were not stored as
- part of the definition, (foo) would try to execute "this is a string"
- as a command.
-
- Given the assignment above, the following work as expected:
-
- (len foo) Result: 16
- (rev foo) Result: gnirts a si siht
- (rev (cap foo)) Result: GNIRTS A SI SIHT
- (sub (rev (cap foo)) 5 8) Result: TS A SI S
-
- Note that, unlike built-in S-Expression operators that return numbers
- or truth values, these operators return strings. If you want to assign
- their return values to other variables, you can do so:
-
- (setq bar (rev (cap foo))) Result: GNIRTS A SI SIHT
-
- But now the S-Expression processor doesn't know the value of "bar" is
- supposed to be a string, rather than a macro to execute. For this you
- need one final special operator, STRING. The STRING operator takes an
- S-Expression as an operand, evaluates it, and then returns its value
- enclosed in '(), so you can use the value as a string is subsequent
- S-Expressions. Use STRING for referencing macros that return strings:
-
- (setq bar (string (rev (cap foo)))) Result: '(GNIRTS A SI SIHT)
-
- STRING is like QUOTE, except that it evaluates its operand before
- applying the quoting, rather than taking the operand literally.
-
- To reference backslash variables or functions that return string
- values, you must use the regular quoting mechanisms:
-
- (setq time '(\v(time)))
- (setq date '(\v(date)))
- assign \%r this is a string
- (setq s1 '(\%r))
-
- That's because backslash items are evaluated BEFORE the S-Expression
- parser ever sees them, and the values of \v(time) and so on are not
- valid S-Expressions, so STRING won't like them.
-
- Finally a brief word on the touchy topic of quoting. Suppose you want
- to include (say) literal parentheses in a string that will later be
- processed by the S-Expression reader (or \fsplit() or \fword()).
- Normally, you can't do this because parentheses are meaningful in
- these contexts. To defeat the normal parsing rules, you can quote the
- parentheses with backslash. However, due to the many levels of string
- processing involved, a surprisingly large amount of backslashes might
- be required, for example:
-
- (setq s '(a b (c d) \\\\\\\\\\\\\\\\(e f (g h) x\\\\\\\\\\\\\\\\) j k))
-
- This is nearly impossible to explain(*). Instead, just remember two
- points:
-
- * In situations like this, it's better to use DEFINE to create the
- string, rather than SETQ. The example above requires only double
- backslashes when DEFINE is used:
- define s '(a b (c d) \\(e f (g h) x\\) j k)
- * The level of quoting depends on how many levels of evaluation the
- string must pass through, which is not always obvious. However,
- the number of backslashes required in any given situation is
- always a power of 2. So if 1 doesn't work, try 2; if 2 doesn't
- work, try 4; if 4 doesn't work, try 8, 16, 32, and so on.
-
- Considerations like this apply in any scripting language (shell, Tcl,
- Perl, Python, etc). The situation is known as "Quoting Hell".
-
- (*) If you really want an explanation, here it is:
-
- * Every SEXP has its backslash items evaluated in a single pass at
- top level before being passed to the SEXP reader, so \%1,
- \v(ftime), etc, can be evaluated up front, freeing the SEXP reader
- of having to know about such things, which in turn makes it much
- more efficient. Therefore one level of quoting is lost right away,
- and therefore you must double each backslash that is to be used as
- a quote.
- * When the SEXP reader sees '\', it treats it as a quote; discards
- it and keeps the next character. Thus '\\' becomes '\'. This would
- be the end of it, except that:
- * The SEXP reader must call itself recursively on its operands, so
- we must double any quotes in the operands: 2^2 = 4.
- * If the result is to be passed as an argument to a macro, the
- backslashes must again be doubled, because the macro processor
- evaluates the arguments before sending them to the macro: 2^3 = 8.
- * If the macro itself is to see the quotes, rather than just the
- result of the quoting, the quotes must be doubled again: 2^4 = 16.
-
- Moral: To create string constants in which grouping characters must be
- quoted, use DEFINE rather than SETQ.

- 9.9. Examples
-
- 9.9.1. Statistics
-
- The following program computes statistics -- means, maxima, mimima,
- variance, standard deviation, and correlation -- from data stored in
- parallel arrays, \&x[] and \&y[], which can contain any mixture of
- integer and floating-point numbers: positive, negative, or zero. Array
- setup and validation are not shown. Except for the traditional FOR
- loop and printing the results at the end, the entire computation is
- done with S-Expressions:
-
-; Initialize sums, maxima, minima, and number of elements
-
- (setq xsum 0 ysum 0 xsum2 0 ysum2 0 xysum 0)
- (setq xmin (setq xmax \&x[1]) ymin (setq ymax \&y[1]))
- (setq n \fdim(&x))
-
-; Loop through elements and accumulate sums, maxima, and minima
-
- for i 1 n 1 {
- (setq x \&x[i] y \&y[i]) ; Notational convenience
- (setq xmax (max xmax x) ymax (max ymax y)) ; X and Y maxima
- (setq xmin (min xmin x) ymin (min ymin y)) ; X and Y minima
- (++ xsum x ysum y) ; X and Y sums
- (++ xsum2 (^ x 2) ysum2 (^ y 2)) ; Sum of X and Y squares
- (++ xysum (* x y)) ; Sum of XY products
- }
-
-; Calculate results
-
- (setq xmean (/ xsum n) ymean (/ ysum n)) ; Mean X and Y
- (setq xss (- xsum2 (/ (^ xsum 2) n))) ; Intermediate values
- (setq yss (- ysum2 (/ (^ ysum 2) n)))
- (setq xyss (- xysum (/ (* xsum ysum) n)))
- (setq xvar (/ xss n) yvar (/ yss n)) ; X and Y variance
- (setq sdx (sqrt xvar) sdy (sqrt yvar)) ; Std deviation in X and Y
- (setq tmp (* xss yss))
- (setq cc (if tmp (/ xyss (sqrt tmp)) 1.0)) ; Correlation coefficient
- show macro xmean ymean xvar yvar sdx sdy cc ; Print the results
-
- The final "if tmp" check accounts for the possibility that both arrays
- contain all 0's. Results can also be printed with "echo CC = \m(cc)",
- or any other desired way. Interestingly, if we had not needed the sum
- of the squares and products, we could have obtained the sums, maxima,
- and minima of the X's and Y's without a loop like this:
-
- (setq xsum (+ \fjoin(&x)) ysum (+ \fjoin(&y)))
- (setq xmax (max \fjoin(&x)) ymax (max \fjoin(&y)))
- (setq xmin (min \fjoin(&x)) ymin (min \fjoin(&y)))
-
- Any Kermit function that returns numbers or lists of numbers can be
- included in an S-Expression as an operand.
- _________________________________________________________________
-
- 9.9.2. Practical Fibonacci Series
-
- The recursive Fibonacci example given previously is simple and
- elegant, but not very useful since it causes memory occupation to grow
- each time it calls itself, until eventually both physical memory and
- disk swap space are filled and the program crashes. Even for small
- arguments, like 17, execution time can be prohibitive:
-
- (setq t1 \v(ftime))
- (setq result (fibonacci 17))
- (setq t2 (- \v(ftime) t1))
- echo FIBONACCI(17) = \m(result): TIME = \ffpround(t2,3)
-
- prints (on a certain rather slow computer):
-
- FIBONACCI(17) = 1597: TIME = 5.861
-
- Any recursive function can be recoded iteratively. The result is not
- as pretty, but execution is far less expensive:
-
- define FIBITER {
- (if (== \%3 0) (\%2) (fibiter (+ \%1 \%2) \%1 (- \%3 1)))
- }
- define FIBONACCI {
- (fibiter 1 0 \%1)
- }
-
- Here's the result on the same computer for the same argument of 17:
-
- FIBONACCI(17) = 1597: TIME = 0.015
-
- (47 times faster.) Execution time increases proportionally to the size
- of the argument in the iterative case, whereas in the recursive case
- it goes up geometrically, quickly reaching infinity.

-
- 9.10. Differences from Algebraic Notation
-
- In C-Kermit:
-
- * Algebraic notation uses infix operators and normal rules of
- operator precedence, with parentheses used to force exceptions to
- the rules; many operations can be included in an expression.
- S-Expressions use prefix operators with no intrinsic precedence;
- each operation is enclosed in parentheses, and the arrangement of
- parentheses determines precedence.
- * Algebraic infix operators require two operands; S-Expression
- prefix operators can accept a variable number of operands.
- * You can use algebraic notation anywhere that C-Kermit accepts a
- number, e.g. "echo \&a[((1+1)*2-1]", but you can use S-Expressions
- only as top-level commands. You can, however, use either algebraic
- or S-Expressions anywhere at all by enclosing them in \fevaluate()
- or \fsexpression(), respectively.
- * You can use any mixture of integer and floating-point numbers in
- S-Expressions, but only integers are permitted in algebraic
- expressions. Outside of S-Expressions, floating point arithmetic
- is supported only by \ffp...() function calls.
- * Operators and operands in S-Expressions must be separated by
- spaces, e.g. "(+ a b)". Spaces are not required in algebraic
- expressions: "((a+b)*c)".
- * When assigning values to backslash variables (such as \%x or
- \&a[2]) using SETQ or LET, you must double the backslash.
-

- Home ]
- _________________________________________________________________
-
- 9.11. Differences from Lisp
-
- * Kermit has a lot of built-in operators not found in Lisp: ++, ^,
- etc.
- * Most dialects of real Lisp do not allow S-Expressions that don't
- start with an operator, for example:
- (a)
- This expression can cause an error in Lisp (even if "a" has a
- value), but is acceptable in Kermit, where it returns the value of
- the variable "a". Similarly, (1) returns the value "1".
- * In real Lisp, EVAL requires exactly one operand. In Kermit, it can
- have 0, 1, 2, or more operands. It returns the value of the last
- operand evaluated.
- * Real Lisp SETQ and LET usually require an even number of operands.
- Kermit allows an odd number, in which case the last (or only)
- variable is undefined (i.e. deleted, destroyed).
- * Kermit does not support ratios such as "7/8". Some Lisp dialects
- accept ratios as numbers, and generate ratios when told to divide
- two integers whose quotient is not a whole number; e.g. in Common
- Lisp:
- [13] USER(37): (/ (+ 1 2 3 4) 3)
- 10/3
- [13] USER(38):
- * The result of (/ 10 3) is 3.333.... Some Lisp dialects truncate
- the result to 3 since both operands are integers, some don't; some
- give the result as a ratio. C-Kermit always gives a floating point
- result when there is a fractional part. If you want an integer
- result, you can use TRUNCATE, FLOOR, or CEILING, e.g. (truncate (/
- 10 3)).
- * There is currently no "bignum" support. Large numbers can be used
- and large results generated, but (as noted in [537]Section 9.2)
- they are accurate only to the precision of the underlying machine.
- \v(math_precision) gives the machine precision as a number of
- decimal digits, e.g. 16.
- * Scientific notation for floating-point numbers is not supported.
- If the magnitude of a number is greater than the precision of the
- underlying hardware, the less-significant digits are shown but
- their values are meaningless. If it the number is too small to be
- represented internally, it is shown as "0.0".
- * Many Lisp features are omitted: List processing (CAR, CDR, etc),
- DEFUN, Lisp-specific control structures, and so on.

-10. FILE TRANSFER
-
- New commands and switches:
-
- SET TRANSFER REPORT { OFF, ON }
- Enables or disables the (new) one-line message printed by
- Kermit after a remote-mode file transfer to indicate the source
- and destination file, complete with path, to let you know where
- the file went.
-
- SEND /TYPE:{TEXT,BINARY}
- Sends only files of the given type (see [542]Section 4).
-
- SEND /NOFOLLOWLINKS:
- (UNIX only) Skip over symbolic links rather than following them
- (default). This applies to wildcard and/or recursive SENDs; if
- a single filename is given, and it happens to be a symbolic
- link, the file it points to is sent.
-
- SEND /FOLLOWLINKS:
- (UNIX only) Follow (resolve) symbolic links. Watch out for
- circular links, endless loops, etc.
-
- SET SEND I-PACKETS { OFF, ON }
- When sending commands to a Kermit server, this tells whether
- command packets should be preceded by an I (information)
- packet, which is used to synchronize parameters prior to
- executing the command. Normally ON. The only reason to set this
- OFF is for communicating with buggy Kermit servers that
- misbehave when an I packet is sent to them. There is also a SET
- RECEIVE I-PACKETS command, but presently it has no effect.
-
- SET TRANSFER MESSAGE [ text ]
- Sets an initial message to be shown in the Last Message field
- of the fullscreen file-transfer display.
-
- SET TRANSFER TRANSLATION { ON, OFF }
- Inhibits or re-enables text-file transfer character-set
- translation globally.
-
- { SEND, MSEND, GET, RECEIVE } /TRANSPARENT
- Inhibits character-set translation for this transfer only.
-
- { GET, RECEIVE } /PIPES:{ON,OFF}
- Overrides global TRANSFER PIPES setting for this transfer only;
- ON allows incoming files with names like "!tar xf -" to be
- opened as pipelines rather than regular files.
-
- The following new "hot keys" are available when Kermit's file-transfer
- display is visible:
-
- D: Turn on debugging, open "debug.log" if not already open.
- d: Turn off debugging but leave log open (if it was open).
- T: Turn on debug-log timestamps.
- t: Turn off debug-log timestamps.
-
- Other improvements:
- * SET FILE DOWNLOAD-DIRECTORY now works for external protocols (e.g.
- sz/rz) too.
- * Improved automatic per-file text/binary switching, described in
- [543]Section 4.
- * When sending a file group (e.g. "send *.*"), failure to open a
- file is no longer fatal; now C-Kermit simply goes ahead to the
- next file.
- * Transaction log entries are now made for external protocols too.

-11. MODEMS AND DIALING
-
- In C-Kermit 8.0, the default modem type for dialing has changed from
- NONE (= DIRECT, meaning no modem) to GENERIC. This change should have
- no impact on direct connections. For dialing, it means that, unless
- you SET MODEM TYPE to a specific type, such as USROBOTICS or CONEXANT,
- Kermit assumes:
-
- 1. The modem uses the Hayes AT command set.
- 2. The modem supports error correction, data compression, and
- hardware flow control and is already configured to use them.
-
- In fact, Kermit assumes the modem is completely configured, and
- therefore does not send it an initialization string or any
- configuration commands. Instead, it sends only the simplest and most
- portable commands:
-
- ATQ0V1 Give dial result codes.
- ATDTnumber Dial the number.
-
- (or ATD or ATDP, as appropriate).
-
- The new defaults work for direct connections and for most modern
- modems on most platforms, and they work much faster than
- "full-treatment" dialing. If the new defaults don't work for you, or
- if you need to perform explicit modem configuations or interactions,
- then set a specific modem type and use the SET MODEM and SET DIAL
- commands as documented in Using C-Kermit.
-
- WARNING: Don't use the generic modem on hosts that do not support
- RTS/CTS flow control. If Xon/Xoff is in use on the serial port,
- you'll need to select a particular modem type so Kermit knows what
- command to give it to enable Xon/Xoff flow control between itself
- and your serial port.
-
- The following new modem types were added in C-Kermit 8.0:
-
- lucent: Lucent Venus chipset
- pctel: PCTel V.90 chipset
- conexant: Conexant (ex-Rockwell) modem family
- zoom-v32bis: New name for "Zoom"
- zoom-v34 Zoom V.34
- zoom-v90 Zoom V.90 56K
- zoom-v92: Zoom V.92 with V.44 data compression
- zoltrix-v34: New name for "zoltrix"
- zoltrix-hsp-v90: Synonym for PCTel
- zoltrix-hcf-v90: Synonym for ITU-T-V250
- smartlink-v90: Synonym for usrobotics (same chipset)
- acer-v90: Synonym for Rockwell-v90
-
- New DIAL-related variables:
-
- \v(dm_hf): Dial modifier: Wait for Hook-Flash.
- \v(dm_wb): Dial modifier: Wait for Bong.
-
- Finally, if dialing fails, Kermit now prints a context-sensitive hint
- suggesting possible reasons and remedies.
-
- Added in C-Kermit 8.0.201: Rudimentary support for Caller ID, for
- use with the ANSWER command. If the modem reports Caller ID
- information, Kermit stores it in variables that you can access after
- the call is answered:
-
- \v(callid_date) The date of the call
- \v(callid_time) The time of the call
- \v(callid_name) The name of the caller
- \v(callid_nmbr) The telephone number of the caller
- \v(callid_mesg) A message
-
- The format of these items depends on the originating and answering
- phone companies and the modems and their configuration.
-
- Not very many modems support Caller ID, and those that do (a) tend to
- have it disabled by default, and (b) use different commands to enable
- it. A quick survey shows of some current models shows:
-
- - USR V.90: No
- - ITU-T V.250: No
- - Lucent Venus: No
- - Diamond Supra: #CID=1
- - Rockwell 56K: #CID=1
- - PCTEL: #CID=1
- - Zoltrix: +VCID=1
- - Conexant: +VCID=1
-
- To use Kermit's Caller ID feature, you have to set the modem to wait
- for at least two rings before answering, and you have to give the
- command to enable Caller ID; for example (after choosing a modem with
- SET MODEM TYPE):
-
- set modem command autoanswer on ATS0=2#CID=1\{13}
- set modem command autoanswer on ATS0=2+VCID=1\{13}
-
- These commands can be undone with:
-
- set modem command autoanswer on ATS0=1#CID=0\{13}
- set modem command autoanswer on ATS0=1+VCID=0\{13}
-
- Kermit presently has no built-in knowledge of the Caller ID
- capabilities or commands of the modems in its database.
-
- Since the variables can be accessed only after the call is answered,
- the only way to refuse a call is to answer it, inspect the variables,
- and then hang it up if desired.

-12. TERMINAL CONNECTION
-
- Now that 7-bit connections are no longer the norm, the default
- terminal bytesize (also called "data size" or "word size") in C-Kermit
- 8.0 is 8 bits, rather than 7 bits as it was in C-Kermit 7.0 and
- earlier:
-
- SET ESCAPE character
- This command, which specifies your CONNECT-mode escape
- character, allows you to specify any ASCII control character in
- a variety of formats. C-Kermit 8.0.201 now also lets you
- specify any 8-bit value, 128-255, as the escape character. In
- the SET ESCAPE command, you can type the 8-bit character
- literally or you can enter its numeric code. Here are examples
- that you can enter from a terminal or console that uses the ISO
- Latin-1 character set:
-
- C-Kermit> set escape Ã
- C-Kermit> set escape 195
- C-Kermit> show escape
- Escape character: Code 195 (Ã): enabled
- C-Kermit>
-
- Both of these commands set the escape character value to 195
- (decimal), which happens to be uppercase letter A with Tilde in
- Latin-1. SHOW ESCAPE and SHOW TERMINAL show the value, as does
- the CONNECT message.
-
- SET TERMINAL AUTODOWNLOAD ERROR { STOP, CONTINUE }
- When Kermit has a terminal connection to another computer, and
- a file transfer is initiated automatically because a Kermit
- packet was received in CONNECT mode (i.e. in the terminal
- screen), this command tells what Kermit should do if the
- transfer fails. The default is to STOP, which leaves Kermit in
- command mode with its file-transfer display showing, so you can
- see that the transfer failed and why. If you SET TERMINAL
- AUTODOWNLOAD ERROR CONTINUE, this causes Kermit to return
- automatically to its terminal screen (i.e. resume its CONNECT
- session) as if the transfer had succeeded; this can be
- desirable if the entire session is under control of a
- host-based script.
-
- SET TERMINAL BYTESIZE { 7, 8 }
- The byte size to use during CONNECT and INPUT command
- execution, which can be more restrictive than the bytesize
- implied by the current PARITY setting, but not less
- restrictive. In C-Kermit 7.0 and earlier, the terminal bytesize
- was 7 by default to protect against the likelihood that parity
- was in use on the connection without the user's knowledge. When
- the terminal bytesize is 8 (as it is in C-Kermit 8.0 and
- later), the user will see garbage in this (increasingly
- unlikely) situation. Note that 8 data bits are required for
- most character sets other than ASCII: Latin-1, UTF-8, and so
- on.
-
- A new command has been added to produce timestamped session logs:
-
- SET TERMINAL SESSION-LOG TIMESTAMPED-TEXT
- Records the terminal session in text mode (like SET TERMINAL
- SESSION-LOG TEXT) but adds a timestamp at the beginning of each
- line. The timestamp format is hh:mm:ss.nnn, and indicates the
- time at which the first character of the line appeared.
-
- In most UNIX versions (those built with the select()-capable CONNECT
- module -- pretty much all the ones that have or could have TELNET
- included), an idle timeout feature has been added:
-
- SET TERMINAL IDLE-TIMEOUT number
- If the number is not 0, then Kermit is to take an action when
- the given amount of time passes with no activity during CONNECT
- mode. If the number is positive it is the maximum number of
- idle seconds; if number is negative it represents milliseconds
- (thousandths of seconds). If 0 is given as the number, there
- are no idle timeouts. Synonym: SET TERMINAL IDLE-LIMIT.
-
- SET TERMINAL IDLE-ACTION { RETURN, HANGUP, EXIT, OUTPUT [ string ] }
- The action to be taken upon an idle timeout in CONNECT mode.
- RETURN to the prompt, HANGUP the connection, EXIT from Kermit,
- or OUTPUT the given string (if no string is given, a NUL (ASCII
- 0) character is sent).
-
- SET TERMINAL IDLE-ACTION { TELNET-NOP, TELNET-AYT }
- Actions that can be selected on Telnet connections only, that
- might be useful if idle limits are enforced by the Telnet
- server or in the TCP/IP protocol: TELNET-NOP sends a "NO
- Operation" (do-nothing) command, which causes no response from
- the server; TELNET-AYT sends an "Are You There" message to the
- server, which should make the server send back a message.
- Neither of these actions interferes with your remote session.
-
- SET TERMINAL IDLE-ACTION is useful for connections to hosts or
- services that automatically log you out after a certain amount of idle
- time, e.g.:
-
- set term idle-timeout 300
- set term idle-action output \32
-
- sends a space (as if you had pressed the space bar) every 300 seconds
- (five minutes) while there is no activity (32 is the ASCII code for
- space).
-
- When C-Kermit returns from CONNECT to command mode, the reason for the
- transition is given in a new variable, \v(cx_status):
-
- 0 No CONNECT command given yet.
- 1 User escaped back manually.
- 2 A trigger string was encountered.
- 3 IKSD entered server mode.
- 4 Application Program Command received from host.
- 5 Idle timeout.
- 6 Telnet protocol error.
- 7 Keystroke macro.
- 8 Time limit exceeded.
- 100 Internal error.
- 101 Carrier required by not detected.
- 102 I/O error on connection.
- 103 Disconnected by host.
- 104 Disconnected by user.
- 105 Session limit exceeded.
- 106 Rejected due to Telnet policy.
- 107 Received kill signal.
-
- Values 100 and above indicate there is no connection.

-13. CHARACTER SETS
-
- See the section on [556]file scanning above, and the section on
- character-set conversion in [557]FTP. Also:
-
- * True support for CP1252 (rather than treating it as Latin-1).
- * Proper handling of C1 values when converting ISO 8-bit text to
- UTF-8.
- * TYPE /CHARACTER-SET: /TRANSLATE-TO: allows specific translations.
- * The TRANSLATE command now works on multiple files.
- * K_CHARSET environment variable to set the file character-set.
- * SET TRANSFER TRANSLATION OFF.
- * FTP client character-set translation ([558]Section 3.7).

-14. DIALOUT FROM TELNET TERMINAL SERVERS
-
- For years, C-Kermit has supported dialing out from Telnet modem
- servers (also called reverse terminal servers or access servers), but
- until now there was no way for Kermit to control the communication
- parameters (speed, parity, etc) on the serial port of the terminal
- server; it had to use whatever was there.
-
- But now, if you make a connection to a server that supports the Telnet
- Com Port Control Option, [563]RFC 2217, you have the same degree of
- control as you would have over a serial port on the computer where
- Kermit is running: SET SPEED, SET FLOW, SET PARITY, SET STOP-BITS,
- SHOW COMM, WAIT, SET CARRIER-WATCH, the modem-signal variables,
- sending Break, and so on, apply to the connection between the terminal
- server and the modem.
-
- For example, using a Cisco Access Server 2509, where specifying a TCP
- port in the 6000's selects a serial port that can be used for dialing
- out:
-
- set host xxx 6001 ; xxx is the IP hostname or address of the server
- (log in if necessary) ; With a script or by hand
- set modem type usr ; Tell Kermit what kind of modem it has
- set speed 57600 ; This affects the server's port
- set flow rts/cts ; Ditto
- dial 7654321
-
- The modem server might or might not require a login sequence. It might
- also allow for automatic authentication, e.g. via Kerberos tickets.
- NOTE: If the modem server requires a login sequence, then REDIAL might
- not work as expected.
-
- When you have a Telnet Com Port connection, your SET SPEED and SET
- FLOW options change automatically to reflect the capabilities of the
- server, rather than those of your local computer.
-
- See the configuration manual for your server for additional
- information. For example, how to set up the server to drop the Telnet
- connection automatically when the telephone call is hung up (e.g.
- "autohangup" on Cisco models).

-15. COPING WITH BROKEN KERMIT PARTNERS
-
- There are lots of faulty Kermit protocol implementations out there,
- found mainly in 3rd-party products ranging from communications
- software packages to file-transfer functions imbedded within devices.
- This topic is covered [569]HERE for C-Kermit 7.0, but C-Kermit 8.0
- adds some additional tricks.
-
- SET ATTRIBUTE RECORD-FORMAT { ON, OFF }
- Allows control of the Kermit's Record-Format attribute. Set
- this to OFF in case incoming file are refused due to unknown or
- invalid record formats if you want to accept the file anyway.
-
- SET SEND I-PACKETS { ON, OFF }
- A Kermit server is supposed to accept I-packets; this is how
- the client lets the server know its capabilities and
- preferences before sending a command. Apparently there is at
- least one Kermit server implementation that does not accept
- I-packets, and does not properly respond with an Error packet
- if it gets one. To get around such situations in C-Kermit 8.0,
- you can use SET SEND I-PACKETS OFF to inhibit the sending of I
- packets. In this case, the client must be able to adjust to the
- server's configuration, rather than the other way around as we
- are used to.
-
- SET PROTOCOL KERMIT {} {} {}
- C-Kermit 6.0 and later automatically send "autoupload" and
- "autodownload" commands when in local mode and you give a file
- transfer command. For example, if you tell kermit to "send
- oofa.txt", Kermit sends "kermit -r" and a carriage return, in
- case you had forgotten to start Kermit on the far end and told
- it to receive a file. If a Kermit program had already been
- started on the far end, it should harmlessly absorb this
- string. However, some Kermit programs violate the Kermit
- protocol definition and treat such strings as Kermit packets
- even though they are not. In such cases, give this command to
- set the Kermit protocol autoupload and download strings to
- nothing, which tells Kermit not to send them. (This is not a
- new feature, but it was not previously included in the "Coping"
- section of the documentation.)

-
-16. NEW COMMAND-LINE OPTIONS
-
- kermit -h Now prints a complete listing of its command-line options,
- rather than an abbreviated list squeezed into a 24x80 space.
-
- -dd Debug, like -d but adds timestamps
- --version Shows C-Kermit version number.
- --noperms Equivalent to SET ATTRIBUTE PROTECTION OFF.
-
- Kermit now accepts a selection of URLs (Universal Resource Locators)
- as its first command-line argument. These are:
-
- telnet:hostname
- Makes a Telnet connection to the given host (IP hostname or
- address).
-
- ftp://[user[:password]@]hostname[/path...]
- Makes an FTP connection to the given host (IP hostname or
- address). If a username is given, Kermit tries to log you in;
- if a password is given, it is used; if not, you are prompted
- for one. If no username is given, an anonymous login is
- performed. If a pathname is included, Kermit tries to GET the
- given file. See [574]Section 3.1.3 for details.
-
- ftps://[user[:password]@]hostname[/path...]
- Makes a secure FTP connection over SSL.
-
- telnets://[user[:password]@]hostname
- Makes a secure Telnet connection over SSL.
-
- kermit://[user[:password]@]hostname[/path...]
- Makes a connection to an [575]Internet Kermit Server.
-
- http://[user[:password]@]hostname[/path...]
- Makes a connection to Web server.
-
- https://[user[:password]@]hostname[/path...]
- Makes a connection to secure Web server.

-17. LOGS
-
- In C-Kermit 8.0, we make an effort to keep passwords out of the debug
- log. This can never be 100% effective, but it's better than before,
- when there were no precautions at all. Whenever Kermit knows it's
- prompting for, parsing, or transmitting a password, it temporarily
- turns off logging and then turns it back on afterwards. This keeps the
- debug log password-free in most common cases, but there can be no
- guarantees.
-
- As noted elsewhere, the new "-dd" command-line option selects a
- timestamped debug log (equivalent to "set debug timestamps on", "log
- debug debug.log").
-
- C-Kermit 8.0 also supports a new timestamped session log via "set
- session-log timestamped-text", "log session".
-
- There have been requests for other kinds of logs, for example a
- command log. These might be added at some point. One person wanted to
- be able to log commands with timestamps, but only commands issued at
- the prompt, not commands from files or macros, and also wanted a
- header line at the beginning showing the date, user, and host. This
- can be done as follows:
-
- .filename := \v(home)commands.log ; (for example)
- fopen /write \%c \m(filename)
- if success {
- fwrite /line \%c \v(date): User=\v(user) Host=\v(host)
- fclose \%c
- set debug timestamps on
- log debug {| grep "CMD(P)" >> \m(filename)} append
- }

-.na
-.SH NAME
-kermit \-
-.B C\(hyKermit 8.0:
-transport\(hy and platform\(hyindependent
-interactive and scriptable communications software.
-.IP
-
-This document is intended to give the beginner sufficient information to make
-basic (if not advanced) use of C\(hyKermit 8.0. Although it might be rather long
-for a Unix manual page, it's still far shorter than the C\(hyKermit manual, which
-should be consulted for advanced topics such as customization, character\(hysets,
-scripting, etc. We also attempt to provide a clear structural overview of
-C\(hyKermit's many capabilities, functional areas, states, and modes and their
-interrelation, that should be helpful to beginners and veterans alike, as well
-as to those upgrading to version 8.0 from earlier releases.
-.PP
-This document is also available as a Web page at:
-.IP
-http://www.columbia.edu/kermit/ckututor.html
-.SH DESCRIPTION
-C\(hyKermit is an all\(hypurpose communications software package from the Kermit
-Project at Columbia University that:
-.PP
-.nf
-\(bu Is portable to many platforms, Unix and non\(hyUnix alike.
-.br
-\(bu Can make both serial and network connections.
-.br
-\(bu Can conduct interactive terminal sessions over its connection.
-.br
-\(bu Can transfer text or binary files over the same connection.
-.br
-\(bu Can convert character sets in the terminal session.
-.br
-\(bu Can convert character sets during text\(hyfile file transfer.
-.br
-\(bu Is customizable in every aspect of its operation.
-.fi
-.PP
-C\(hyKermit is a modem program, a Telnet client, an Rlogin client, an FTP
-client, an HTTP client, and on selected platforms, also an X.25 client. It
-can make its own secure Internet connections using IETF\(hyapproved security
-methods including Kerberos IV, Kerberos V, SSL/TLS, and SRP and it can also
-make SSH connections through your external SSH client application. It can
-be the far\(hyend file\(hytransfer or client/server partner of your desktop
-Kermit client. It can also accept incoming dialed and network connections.
-It can even be installed as an Internet service on its own standard TCP
-socket, 1649 [RFC2839, RFC2840].
-.PP
-And perhaps most important, everything you can do "by hand" (interactively)
-with C\(hyKermit, can be "scripted" (automated) using its built\(hyin
-cross\(hyplatform transport\(hyindependent script programming language, which
-happens to be identical to its interactive command language.
-.PP
-This manual page offers an overview of C\(hyKermit 8.0 for Unix ("Unix" is an
-operating system family that includes AIX, DG/UX, FreeBSD, HP\(hyUX, IRIX,
-Linux, Mac OS X, NetBSD, OpenBSD, Open Server, Open Unix, QNX, Solaris,
-SunOS, System V R3, System V R4, Tru64 Unix, Unixware, Xenix, and many
-others). For thorough coverage, please consult the published C\(hyKermit
-manual and supplements (see DOCUMENTATION below). For further information
-about C\(hyKermit, Kermit software for other platforms, and Kermit manuals,
-visit the Kermit Project website:
-.PP
- http://www.columbia.edu/kermit/
-.PP
-This is a longer\(hythan\(hyaverage manual page, and yet it barely scratches the
-surface. Don't be daunted. C\(hyKermit is a large and complex package,
-evolving over decades of practice and experience, but that doesn't mean
-it's hard to learn or use. Its most commonly used functions are explained
-here with pointers to additional information elsewhere.
-.SH SYNOPSIS
-.B kermit [
-.I filename
-.B ] [
-.I options
-.B ] [ {=,\-\-,+}
-.I text
-.B ] ]
-.PP
-or:
-.PP
-.B kermit
-.I URL
-.PP
-If the first command\(hyline argument is the name of a file, interactive\(hymode
-commands are executed from the file. The '=' (or "\-\-") argument tells
-Kermit not to parse the remainder of the command line, but to make the
-words following '=' available as \e%1, \e%2, ... \e%9. The "+" argument is
-like "=" but for use in "kerbang scripts" (explained below). A second
-command\(hyline format allows the one and only argument to be a Telnet, FTP,
-HTTP, or IKSD URL.
-.PP
-Order of execution:
-.TP
- 1.
-The command file (if any).
-.TP
-.nf
- 2.
-The initialization file, if any, unless suppressed with \-Y.
-.fi
-.TP
- 3.
-The customization file (if it is executed by the initialization file).
-.TP
- 4.
-The command\(hyline URL (if any, and if so, execution stops here).
-.TP
- 5.
-Command\(hyline options (if any).
-.TP
- 6.
-Interactive commands.
-.PP
-Some command\(hyline options can cause actions (such as \-s to send a file);
-others just set parameters. If any action options are included on the
-command line, Kermit exits when finished unless also given the \-S ("stay")
-option. If no action options are given, no initialization or command files
-contained an EXIT or QUIT command, and no fatal errors occurred, Kermit
-issues its prompt and waits for you to type commands.
-.IP
-Bear in mind that C\(hyKermit can be built with selected features
-disabled, and also that certain features are not available on all
-platforms. For example, C\(hyKermit can't be built with TCP/IP
-support on a platform that does not have TCP/IP header files and
-libraries (and even if Kermit does include TCP/IP support, it
-can't be used to make TCP/IP connections on a computer that does
-not have a TCP/IP stack installed). If your version of lacks
-C\(hyKermit a feature mentioned here, use its SHOW FEATURES command to
-see what might have been excluded.
-.PP
-C\(hyKermit has three kinds of commands: regular single\(hyletter command\(hyline
-options, extended\(hyformat command\(hyline options, and interactive commands.
-.PP
-Like most Unix commands, C\(hyKermit can be be given options on the command
-line. But C\(hyKermit also can be used interactively by giving it commands
-composed of words, which are more intuitive than cryptic command\(hyline
-options, and more flexible too. In other words, you don't have to use
-C\(hyKermit's command\(hyline options, but they are available if you want to. (By
-the same token, you don't have to use its interactive commands either \(hy\(hy
-you can use either or both in any combination.)
-.PP
-C\(hyKermit is generally installed in the PATH as "kermit", and therefore is
-invoked by typing the word "kermit" (lowercase) at the shell prompt, and
-then pressing the Return or Enter key. If you wish to include command\(hyline
-options, put them after the word "kermit" but before pressing Return or
-Enter, separated by spaces, for example:
-.PP
- $ kermit \-s ckermit.tar.gz
-.PP
-('$' is the shell prompt; "kermit \-s ckermit.tar.gz" is what you type,
-followed by Return or Enter.)
-.SH OPTIONS
-Here is a list of C\(hyKermit's single\(hyletter command\(hyline options, which
-start with a single dash (\-), in ASCII ("alphabetical") order. Alphabetic
-case is significant (\-A is not the same as \-a). Action options are

-.SH COMMAND LANGUAGE
-C\(hyKermit's interactive command language is the subject of a 622\(hypage book
-and another several hundred pages of updates, far too much for a manual
-page. But it's not hard to get started. At the shell prompt, just type
-"kermit" to get C\(hyKermit's interactive command prompt:
-.PP
-.nf
- $ kermit
- (/current/directory) C\-Kermit>
-.fi
-.PP
-Begin by typing "help" (and then press the Return or Enter key) for a
-top\(hylevel overview, read it, and go from there. Your second command should
-probably be "intro" (introduction). Note the prompt shows your current
-directory (unless you tell Kermit to prompt you with something else).
-.PP
-Interactive commands are composed mainly of regular English words, usually
-in the form of imperative sentences, such as:
-.PP
- send oofa.txt
-.PP
-which tells Kermit to send (transfer) the file whose name is oofa.txt, or:
-.PP
- set transfer mode automatic
-.PP
-which sets Kermit's "transfer mode" to "automatic" (whatever that means).
-.PP
-While typing commands, you can abbreviate, ask for help (by pressing the
-"?" key anywhere in a command), complete keywords or filenames (with the
-Tab or Esc key), and edit your typing with Backspace or Delete, Ctrl\-W,
-Ctrl\-U, etc. You can also recall previous commands, save your command
-history, and who knows what else. Give the INTRO command for details.
-.PP
-C\(hyKermit has hundreds of commands, and they can be issued in infinite
-variety and combinations, including commands for:
-.nf
-.PP
-\(bu Making connections (SET LINE, DIAL, TELNET, SSH, FTP, ...)
-.br
-\(bu Breaking connections (HANGUP, CLOSE)
-.br
-\(bu Transferring files (SEND, GET, RECEIVE, MOVE, RESEND, ...)
-.br
-\(bu Establishing preferences (SET)
-.br
-\(bu Displaying preferences (SHOW)
-.br
-\(bu Managing local files (CD, DELETE, MKDIR, DIR, RENAME, TYPE, ...)
-.br
-\(bu Managing remote files (RCD, RDEL, RMKDIR, RDIR, ...)
-.br
-\(bu Using local files (FOPEN, FCLOSE, FREAD, FWRITE)
-.br
-\(bu Programming (TAKE, DEFINE, IF, FOR, WHILE, SWITCH, DECLARE, ...)
-.br
-\(bu Interacting with the user (ECHO, ASK, ...)
-.br
-\(bu Interacting with a remote computer (INPUT, OUTPUT, ...)
-.br
-\(bu Interacting with local programs (RUN, EXEC, PTY, ...)
-.br
-\(bu Logging things (LOG SESSION, LOG PACKETS, LOG DEBUG, ...)
-.PP
-.fi
-And of course QUIT or EXIT to get out and HELP to get help, and for
-programmers: loops, decision making, variables, arrays, associative arrays,
-integer and floating point arithmetic, macros, built\(hyin and user\(hydefined
-functions, string manipulation, pattern matching, block structure, scoping,
-recursion, and all the rest. To get a list of all C\(hyKermit's commands, type
-a question mark (?) at the prompt. To get a description of any command,
-type HELP followed by the name of the command, for example:
-.PP
- help send
-.PP
-The command interruption character is Ctrl\-C (hold down the Ctrl key and
-press the C key).
-.PP
-The command language "escape character", used to introduce variable names,
-function invocations, and so on, is backslash (\). If you need to include a
-literal backslash in a command, type two of them, e.g.:
-.PP
- get c:\ek95\ek95custom.ini
-.SS Command Files, Macros, and Scripts
-A file containing Kermit commands is called a Kermit command file or Kermit
-script. It can be executed with Kermit's TAKE command:
-.PP
- (/current/dir) C\-Kermit> take commandfile
-.PP
-(where "commandfile" is the name of the command file). Please don't pipe a
-command file into Kermit's standard input (which might or might not work);
-if you have Kermit commands in a file, tell Kermit to TAKE the file.
-.PP
-In Unix only, a Kermit command file can also be executed directly by
-including a "kerbang" line as the first line of the file:
-.PP
- #!/usr/local/bin/kermit +
-.PP
-That is, a top line that starts with "#!", followed immediately by the full
-path of the Kermit executable, and then, if the Kermit script is to be
-given arguments on the command line, a space and a plus sign. The script
-file must also have execute permission:
-.PP
- chmod +x commandfile
-.PP
-Except for the " +" part, this is exactly the same as you would do for a
-shell script, a Perl script, etc. Here's a simple but useless example
-script that regurgitates its arguments (up to three of them):
-.PP
- #!/usr/local/bin/kermit +
- if defined \e%1 echo "Argument 1: \e%1"
- if defined \e%2 echo "Argument 2: \e%2"
- if defined \e%3 echo "Argument 3: \e%3"
- if defined \e%4 echo "etc..."
- exit
-.PP
-If this file is stored in your current directory as "commandfile", then:
-.PP
- ./commandfile one two three four five
-.PP
-prints:
-.PP
- Argument 1: one
- Argument 2: two
- Argument 3: three
- etc...
-.PP
-This illustrates the basic structure of a standalone Kermit script: the
-"kerbang line", then some commands. It should end with "exit" unless you
-want the Kermit prompt to appear when it is finished. \e%1 is the first
-argument, \e%2 the second, and so on.
-.PP
-You can also create your own commands by defining named macros composed of
-other Kermit commands (or macros). For example:
-.PP
-.nf
- define mydelete {
- local trash
- assign trash \ev(home)trashcan/
- if not defined \e%1 end 1 "Delete what?"
- if wild \e%1 {
- end 1 "Deleting multiple files is too scary"
- }
- if not exist \e%1 end 1 "I can't find \e%1"
- if not directory \em(trash) {
- mkdir \em(trash)
- if fail end 1 "No trash can"
- }
- rename /list \e%1 \em(trash)
- }
- define myundelete {
- local trash
- assign trash \ev(home)trashcan/
- if not defined \e%1 end 1 "Undelete what?"
- if wild \e%1 {
- end 1 "Undeleting multiple files is too hard"
- }
- if not directory \em(trash) end 1 "No trash can"
- if not exist \em(trash)\e%1 {
- end 1 "I can't find \e%1 in trash can"
- }
- rename /list \em(trash)\e%1 .
- }
-.PP
-.fi
-These sample macros are not exactly production quality (they don't handle
-filenames that include path segments, they don't handle multiple files,
-etc), but you get the idea: you can pass arguments to macros, and they can
-check them and make other kinds of decisions. If you put the above lines
-into your initialization or customization file (explained below), you'll
-have MYDELETE and MYUNDELETE commands available every time you start
-Kermit, at least as long as you don't suppress execution of the
-initialization file. (Exercise for the reader: Make these macros generally
-useful: remove limitations, add trashcan display, browsing, emptying, etc.)
-.PP
-Kerbang scripts execute without the initialization file. This to keep them
-portable and also to make them start faster. If you want to write Kerbang
-scripts that depend on the initialization file, include the command
-.PP
- take \ev(home).kermrc
-.PP
-at the desired spot in the script. By the way, \ev(xxx) is a built\(hyin
-variable (xxx is the variable name, "home" in this case). To see what
-built\(hyin variables are available, type "show variables" at the C\(hyKermit
-prompt. To see what else you can show, type "show ?". \em(xxx) is a user
-defined variable (strictly speaking, it is a macro used as a variable).
-.SS Command List
-C\(hyKermit has more than 200 top\(hylevel commands, and some of these, such as
-SET, branch off into hundreds of subcommands of their own, so it's not
-practical to describe them all here. Instead, here's a concise list of the
-most commonly used top\(hylevel commands, grouped by category. To learn about
-each command, type "help" followed by the command name, e.g. "help set".
-Terms such as Command state and Connect state are explained in subsequent
-sections.
-.PP
-Optional fields are shown in [ brackets ]. "filename" means the
-name of a single file. filespec means a file specification that is allowed
-to contain wildcard characters like '*' to match groups of files. options
-are (optional) switches like /PAGE, /NOPAGE, /QUIET, etc, listed in the
-HELP text for each command. Example:
-.PP
-.nf
- send /recursive /larger:10000 /after:\-1week /except:*.txt *
-.fi
-.PP
-which can be read as "send all the files in this directory and all the ones
-underneath it that are larger than 10000 bytes, no more than one week old,
-and whose names don't end with ".txt".

-.PP
-.fi
-This is called menu on demand: you get a menu when you want one, but menus
-are not forced on you even when know what you're doing. Note that you can
-also abbreviate most keywords, and you can complete them with the Tab or
-Esc key. Also note that ? works for filenames too, and that you can use it
-in the middle of a keyword or filename, not just at the beginning. For
-example, "send x?" lists all the files in the current directory whose names
-start with 'x'.
-.SH INITIALIZATION FILE
-In its default configuration, C\(hyKermit executes commands from a file
-called .kermrc in your home directory when it starts, unless it is given the
-\-Y or \-y command\(hyline option. Custom configurations might substitute a shared
-system\(hywide initialization file. The SHOW FILE command tells what
-initialization file, if any, was used. The standard initialization file
-"chains" to an individual customization file, .mykermc, in the home directory,
-in which each user can establish her/his own preferences, define macros, and
-so on.
-.PP
-Since execution of the initialization file (at least the standard one)
-makes C\(hyKermit take longer to start, it might be better not to have an
-initialization file, especially now that Kermit's default startup
-configuration is well attuned to modern computing and networking \(hy\(hy in
-other words, you no longer have do anything special to make Kermit
-transfers go fast. So instead of having an initialization file that is
-executed every time Kermit starts, you might consider making one or more
-kerbang scripts (with names other that .kermrc) that do NOT include an
-"exit" command, and invoke those when you need the settings, macro
-definitions, and/or scripted actions they contain, and invoke C\(hyKermit
-directly when you don't.
-.PP
-To put it another way... We still distribute the standard initialization
-file since it's featured in the manual and backwards compatibility is
-important to us. But there's no harm in not using it if you don't need the
-stuff that's in it (services directory, dialing directory, network
-directory, and associated macro definitions). On the other hand, if there
-are settings or macros you want in effect EVERY time you use Kermit, the
-initialization file (or the customization file it chains to) is the place
-to put them, because that's the only place Kermit looks for them
-automatically each time you start it.
-.SH MODES OF OPERATION
-Kermit is said to be in Local mode if it has made a connection to another
-computer, e.g. by dialing it or establishing a Telnet connection to it. The
-other computer is remote, so if you start another copy of Kermit on the
-remote computer, it is said to be in Remote mode (as long as it has not
-made any connections of its own). The local Kermit communicates over the
-communications device or network connection, acting as a conduit between
-the the remote computer and your keyboard and screen. The remote Kermit is
-the file\(hytransfer partner to the local Kermit and communicates only through
-its standard input and output.
-.PP
-At any moment, a Kermit program can be in any of the following states. It's
-important to know what they are and how to change from one to the other.
-.TP
-Command state
-In this state, Kermit reads commands from:
-.sp
-\(bu Your keyboard; or:
-.br
-\(bu A file, or:
-.br
-\(bu A macro definition.
-.sp
-You can exit from Command state back to Unix with the EXIT or QUIT
-command (same thing). You can enter Connect state with any of various
-commands (CONNECT, DIAL, TELNET, etc). You can enter file transfer
-state with commands like SEND, RECEIVE, and GET. You can enter Server
-state with the SERVER command. The TAKE command tells Kermit to read
-and execute commands from a file. The (perhaps implied) DO command
-tells Kermit to read and execute commands from a macro definition.
-While in Command state, you can interrupt any command, macro, or
-command file by typing Ctrl\-C (hold down the Ctrl key and press the C
-key); this normally brings you back to the prompt.
-.TP
-Shell state
-You can invoke an inferior shell or external command from the Kermit
-command prompt by using the PUSH, RUN (!), EDIT, or BROWSE command.
-While the inferior shell or command is active, Kermit is suspended and
-does nothing. Return to Kermit Command state by exiting from the
-inferior shell or application.
-.TP
-Connect state
-In this state, which can be entered only when in Local mode (i.e. when
-Kermit has made a connection to another computer), Kermit is acting as
-a terminal to the remote computer. Your keystrokes are sent to the
-remote computer and characters that arrive over the communication
-connection are displayed on your screen. This state is entered when
-you give a CONNECT, DIAL, TELNET, RLOGIN, or IKSD command. You can
-return to command state by logging out of the remote computer, or by
-typing:
-.sp
- Ctrl\-\ec
-.sp
-That is: Hold down the Ctrl key and press the backslash key, then let
-go of the Ctrl key and press the C key. This is called escaping back.
-Certain other escape\(hylevel commands are also provided; type Ctrl\-\e?
-for a list. For example, you can enter Shell state with:
-.sp
- Ctrl\-\e!
-.sp
-To send a Ctrl\-\e to the host while in Connect state, type two of them
-in a row. See HELP CONNECT and HELP SET ESCAPE for more info.
-.TP
-Local file\(hytransfer state
-In this state, Kermit is sending packets back and forth with the other
-computer in order to transfer a file or accomplish some other
-file\(hyrelated task. And at the same time, it is displaying its progress
-on your screen and watching your keyboard for interruptions. In this
-state, the following single\(hykeystroke commands are accepted:
-.sp
-.RS
-.TP
-X
-Interrupt the current file and go on to the next (if any).
-.TP
-Z
-Interrupt the current file and skip all the rest.
-.TP
-E
-Like Z but uses a "stronger" protocol (use if X or Z don't work).
-.TP
-Ctrl\-C
-Interrupt file\(hytransfer mode (use if Z or E don't work).
-.sp
-.RE
-Kermit returns to its previous state (Command or Connect) when the
-transfer is complete or when interrupted successfully by X, Z, E, or
-Ctrl\-C (hold down the Ctrl key and press the C key).
-.TP
-Remote file\(hytransfer state
-In this state, Kermit is exchanging file\(hytransfer packets with its
-local partner over its standard i/o. It leaves this state
-automatically when the transfer is complete. In case you find your
-local Kermit in Connect state and the remote one in File\(hytransfer
-state (in which it seems to ignore your keystrokes), you can usually
-return it to command state by typing three Ctrl\-C's in a row. If that
-doesn't work, return your local Kermit to Command state (Ctrl\-\e C) and
-type "e\(hypacket" and then press the Return or Enter key; this forces a
-fatal Kermit protocol error.
-.TP
-Remote Server state
-This is like Remote File\(hytransfer state, except it never returns
-automatically to Command state. Rather, it awaits further instructions
-from the client program; that is, from your Local Kermit program. You
-can return the Remote Server to its previous state by issuing a
-"finish" command to the client, or if you are in Connect state, by
-typing three Ctrl\-C's in a row. You can tell the server job to log out
-and break the connection by issuing a "bye" command to the client.
-.TP
-Local Server state
-Like Remote\(hyServer state, but in local mode, and therefore with its
-file\(hytransfer display showing, and listening for single\(hykey commands,
-as in Local File\(hytransfer state. Usually this state is entered
-automatically when a remote Kermit program gives a GET command.
-.sp
-C\(hyKermit, Kermit 95, and MS\(hyDOS Kermit all can switch automatically from
-Connect state to Local File\(hytransfer state when you initiate a file
-transfer from the remote computer by starting Kermit and telling it to send
-or get a file, in which case, Connect state is automatically resumed after
-the file transfer is finished.
-.sp
-Note that C\(hyKermit is not a terminal emulator. It is a communications
-application that you run in a terminal window (e.g. console or Xterm). The
-specific emulation, such as VT100, VT220, Linux Console, or Xterm, is
-provided by the terminal window in which you are running C\(hyKermit. Kermit
-95 and MS\(hyDOS Kermit, on the other hand, are true terminal emulators. Why
-is C\(hyKermit not a terminal emulator? CLICK HERE to read about it.
-.SH MAKING CONNECTIONS
-Here is how to make different kinds of connections using interactive Kermit
-commands (as noted above, you can also make connections with command\(hyline
-options). Note that you don't have to make connections with Kermit. It can
-also be used on the far end of a connection as the remote file transfer and
-management partner of your local communications software.
-.TP
-Making a Telnet Connection
-At the C\(hyKermit command prompt, simply type:
-.sp
-.nf
- telnet foo.bar.com
-.fi
-.sp
-(substituting desired hostname or address).
-You can also include a port number:
-.sp
-.nf
- telnet xyzcorp.com 3000 ;
-.fi
-.sp
-If the connection is successful, Kermit automically enters Connect
-state. When you logout from the remote host, Kermit automatically
-returns to its prompt. More info: HELP TELNET, HELP SET TELNET, HELP
-SET TELOPT. Also see the IKSD section below.
-.TP
-Making an Rlogin connection
-This is just like Telnet, except you have to be root to do it because
-Rlogin uses a privileged TCP port:
-.sp
-.nf
- rlogin foo.bar.com
-.fi
-.sp
-More info: HELP RLOGIN.
-.TP
-Making an SSH Connection
-Unlike Telnet and Rlogin, SSH connections are not built\(hyin, but
-handled by running your external SSH client through a pseudoterminal.
-Using C\(hyKermit to control the SSH client gives you all of Kermit's
-features (file transfer, character\(hyset conversion, scripting, etc)
-over SSH.
-.sp
- ssh foo.bar.com
-.sp
-More info: HELP SSH, HELP SET SSH.
-.TP
-Dialing with a Modem
-If it's an external modem, make sure it is connected to a usable
-serial port on your computer with a regular (straight\(hythrough) modem
-cable, and to the telephone jack with a telephone cable, and that it's
-turned on. Then use these commands:
-.sp
-.nf
- set modem type usrobotics ; Or other supported type
- set line /dev/ttyS0 ; Specify device name
- set speed 57600 ; Or other desired speed
- set flow rts/cts ; Most modern modems support this
- set dial method tone ; (or pulse)
- dial 7654321 ; Dial the desired number
-.fi
-.sp
-Type "set modem type ?" for a list of supported modem types. If you
-omit the SET MODEM TYPE command, the default type is
-"generic\(hyhigh\(hyspeed", which should work for most modern AT\(hycommand\(hyset
-modems. If the line is busy, Kermit redials automatically. If the call
-does not succeed, use "set dial display on" and try it again to watch
-what happens. If the call succeeds, Kermit enters Connect state
-automatically and returns to its prompt automatically when you log out
-from the remote computer or the connection is otherwise lost.
-.sp
-You can also dial from a modem that is accessible by Telnet, e.g. to a
-reverse terminal server. In this case the command sequence is:
-.sp
-.nf
- set host ts.xxx.com 2000 ; Terminal\(hyserver and port
- set modem type usrobotics ; Or other supported type
- set dial method tone ; (or pulse)
- dial 7654321 ; Dial the desired number
-.fi
-.sp
-If the terminal server supports the Telnet Com Port Option, RFC 2217,
-you can also give serial\(hyport related commands such as SET SPEED, SET
-PARITY, and so on, and Kermit relays them to the terminal server using
-the protocol specified in the RFC.
-.sp
-More info: HELP SET MODEM, HELP SET LINE, HELP SET SPEED, HELP SET
-FLOW, HELP DIAL, HELP SET DIAL, HELP SET MODEM, HELP SET
-CARRIER\-WATCH, SHOW COMMUNICATIONS, SHOW MODEM, SHOW DIAL.
-.TP
-Direct Serial Port
-Connect the two computers, A and B, with a null modem cable (or two
-modem cables interconnected with a null\(hymodem adapter or modem
-eliminator). From Computer A:
-.sp
-.nf
- set modem type none ; There is no modem
- set line /dev/ttyS0 ; Specify device name
- set carrier\-watch off ; If DTR CD are not cross\(hyconnected
- set speed 57600 ; Or other desired speed
- set flow rts/cts ; If RTS and CTS are cross\(hyconnected
- set parity even ; (or "mark" or "space", if necessary)
- set stop\-bits 2 ; (rarely necessary)
- set flow xon/xoff ; If you can't use RTS/CTS
- connect ; Enter Connect (terminal) state
-.fi
-.sp
-This assumes Computer B is set up to let you log in. If it isn't, you
-can run a copy of Kermit on Computer B and follow approximately the
-same directions. More info: As above plus HELP CONNECT.
-.PP
-With modems or direct serial connections, you might also have to "set
-parity even" (or "mark" or "space") if it's a 7\(hybit connection.
-.PP
-Of the connection types listed above, only one can be open at a time.
-However, any one of these can be open concurrently with an FTP or HTTP
-session. Each connection type can be customized to any desired degree,
-scripted, logged, you name it. See the manual.
-.PP
-NOTE: On selected platforms, C\(hyKermit also can make X.25 connections. See
-the manual for details.
-.SH TRANSFERRING FILES WITH KERMIT
-There is a widespread and persistent belief that Kermit is a slow protocol.
-This is because, until recently, it used conservative tuning by default to
-make sure file transfers succeeded, rather than failing because they
-overloaded the connection. Some extra commands (or command\(hyline options,
-like \-Q) were needed to make it go fast, but nobody bothered to find out
-about them. Also, it takes two to tango: most non\(hyKermit\(hyProject Kermit
-protocol implementations really ARE slow. The best file\(hytransfer partners
-for C\(hyKermit are: another copy of C\(hyKermit (7.0 or later) and Kermit 95.
-These combinations work well and they work fast by default. MS\(hyDOS Kermit
-is good too, but you have to tell it to go fast (by giving it the FAST
-command).
-.PP
-Furthermore, all three of these Kermit programs support "autodownload" and
-"autoupload", meaning that when they are in Connect state and a Kermit
-packet comes in from the remote, they automatically switch into file
-transfer mode.
-.PP
-And plus, C\(hyKermit and K95 also switch automatically between text and
-binary mode for each file, so there is no need to "set file type binary" or
-"set file type text", or to worry about files being corrupted because they
-were transferred in the wrong mode.
-.PP
-What all of these words add up to is that now, when you use up\(hyto\(hydate
-Kermit software from the Kermit Project, file transfer is not only fast,
-it's ridiculously easy. You barely have to give any commands at all.
-.TP
-Downloading Files
-Let's say you have Kermit 95, C\(hyKermit, or MS\(hyDOS Kermit on your
-desktop computer, with a connection to a Unix computer that has
-C\(hyKermit installed as "kermit". To download a file (send it from Unix
-to your desktop computer), just type the following command at your
-Unix shell prompt:
-.sp
- kermit \-s oofa.txt
-.sp
-(where oofa.txt is the filename). If you want to send more than one
-file, you can put as many filenames as you want on the command line,
-and they can be any combination of text and binary:
-.sp
- kermit \-s oofa.txt oofa.zip oofa.html oofa.tar.gz
-.sp
-and/or you can use wildcards to send groups of files:
-.sp
- kermit \-s oofa.*
-.sp
-If you want to send a file under an assumed name, use:
-.sp
- kermit \-s friday.txt \-a today.txt
-.sp
-This sends the file friday.txt but tells the receiving Kermit that its
-name is today.txt. In all cases, as noted, when the file transfer is
-finished, your desktop Kermit returns automatically to Connect state.
-No worries about escaping back, re\(hyconnecting, text/binary mode
-switching. Almost too easy, right?
-.TP
-Uploading Files
-To upload files (send them from your desktop computer to the remote
-Unix computer) do the same thing, but use the \-g (GET) option instead
-of \-s:
-.sp
- kermit \-g oofa.txt
-.sp
-This causes your local Kermit to enter server mode; then the remote
-Kermit program requests the named file and the local Kermit sends it
-and returns automatically to Connect state when done.
-.sp
-If you want to upload multiple files, you have have use shell quoting
-rules, since these aren't local files:
-.sp
-.nf
- kermit \-g "oofa.txt oofa.zip oofa.html oofa.tar.gz"
- kermit \-g "oofa.*"
-.fi
-.sp
-If you want to upload a file but store it under a different name, use:
-.sp
- kermit \-g friday.txt \-a today.txt
-.TP
-Kermit Transfers the Old\(hyFashioned Way
-If your desktop communications software does not support autoupload or
-autodownload, or it does not include Kermit server mode, the procedure
-requires more steps.
-.sp
-To download a file, type:
-.sp
- kermit \-s filename
-.sp
-on the host as before, but if nothing happens automatically in
-response to this command, you have to switch your desktop
-communications software into Kermit Receive state. This might be done
-by escaping back using keyboard characters or hot keys (Alt\-x is
-typical) and/or with a command (like RECEIVE) or a menu. When the file
-transfer is complete, you have to go back to Connect state, Terminal
-emulation, or whatever terminology applies to your desktop
-communications software.
-.sp
-To upload a file, type:
-.sp
- kermit \-r
-.sp
-on the host (rather than "kermit \-g"). This tells C\(hyKermit to wait
-passively for a file to start arriving. Then regain the attention of
-your desktop software (Alt\-x or whatever) and instruct it to send the
-desired file(s) with Kermit protocol. When the transfer is finished,
-return to the Connect or Terminal screen.
-.TP
-If File Transfer Fails
-Although every aspect of Kermit's operation can be finely tuned, there
-are also three short and simple "omnibus tuning" commands you can use
-for troubleshooting:
-.RS
-.TP
-FAST
-Use fast file\(hytransfer settings. This has been the default since
-C\(hyKermit 7.0 now that most modern computers and connections
-support it. If transfers fail with fast settings, try . . .
-.TP
-CAUTIOUS
-Use cautious but not paranoid settings. File transfers, if they
-work, will go at medium speed. If not, try . . .
-.TP
-ROBUST
-Use the most robust, resilient, conservative, safe, and reliable
-settings. File transfers will almost certainly work, but they
-will be quite slow (of course this is a classic tradeoff; ROBUST
-was C\(hyKermit's default tuning in versions 6.0 and earlier, which
-made everybody think Kermit protocol was slow). If ROBUST doesn't
-do the trick, try again with SET PARITY SPACE first in case it's
-not an 8\(hybit connection.
-.RE
-.sp
-Obviously the success and performance of a file transfer also depends
-on C\(hyKermit's file transfer partner. Up\(hyto\(hydate, real Kermit Project
-partners are recommended because they contain the best Kermit protocol
-implementations and because we can support them in case of trouble.
-.sp
-If you still have trouble, consult Chapter 10 of Using C\(hyKermit, or
-send email to kermit\(hysupport@columbia.edu.
-.TP
-Advanced Kermit File\(hyTransfer Features
-Obviously there is a lot more to Kermit file transfer, including all
-sorts of interactive commands, preferences, options, logging,
-debugging, troubleshooting, and anything else you can imagine but
-that's what the manual and updates are for. Here are a few topics you
-can explore if you're interested by Typing HELP for the listed
-commands:
-.RS
-.TP
-Logging transfers:
-LOG TRANSACTIONS (HELP LOG)
-.TP
-Automatic per\(hyfile text/binary mode switching:
-SET TRANSFER MODE { AUTOMATIC, MANUAL } (HELP SET TRANSFER).
-.TP
-Cross\(hyplatform recursive directory tree transfer:
-SEND /RECURSIVE, GET /RECURSIVE (HELP SEND, HELP GET).
-.TP
-File collision options:
-SET FILE COLLISION { OVERWRITE, BACKUP, DISCARD, ... } (HELP SET FILE).
-.TP
-Update: Transfer only files that changed since last time:
-SET FILE COLLISION UPDATE (HELP SET FILE).
-.TP
-Filename selection patterns:
-(HELP WILDCARD).
-.TP
-Flexible file selection:
-SEND (or GET) /BEFORE /AFTER /LARGER /SMALLER /TYPE /EXCEPT, ...
-.TP
-Character\(hyset conversion:
-SET { FILE, TRANSFER } CHARACTER\-SET, ASSOCIATE, ...
-.TP
-File/Pathname control:
-SET { SEND, RECEIVE } PATHNAMES, SET FILE NAMES.
-.TP
-Atomic file movement:
-SEND (or GET) /DELETE /RENAME /MOVE\-TO
-.TP
-Transferring to/from standard i/o of other commands:
-SEND (or GET) /COMMAND
-.TP
-Recovery of interrupted transfer from point of failure:
-RESEND, REGET (HELP RESEND, HELP REGET).
-.RE
-.TP
-Non\(hyKermit File Transfer
-You can also use C\(hyKermit to transfer files with FTP or HTTP Internet
-protocols; see below.
-.sp
-On a regular serial or Telnet connection where the other computer
-doesn't support Kermit protocol at all, you have several options. For
-example, if your desktop communications software supports Zmodem, use
-"rz" and "sz" on the host rather than Kermit. But if Kermit is your
-desktop software, and you are using it to make calls or network
-connections to other computers that don't support Kermit protocol (or
-that don't have a good implementation of it), then if your computer
-also has external X, Y, or Zmodem programs that are redirectable,
-Kermit can use them as external protocols. HELP SET PROTOCOL for
-details.
-.sp
-You can also capture "raw" data streams from the other computer with
-LOG SESSION (HELP LOG and HELP SET SESSION\-LOG for details), and you
-can upload files without any protocol at all with TRANSMIT (HELP
-TRANSMIT, HELP SET TRANSMIT).
-.SH KERMIT'S BUILT\(hyIN FTP AND HTTP CLIENTS
-Kermit's FTP client is like the regular Unix FTP client that you're used
-to, but with some differences:
-.TP
-\(bu
-It has lots more commands and features.
-.TP
-\(bu
-Each FTP command must be prefixed with "ftp", for example "ftp open",
-"ftp get", "ftp bye", etc (this is not strictly true, but until you're
-more familiar with it, it's best to follow this rule).
-.TP
-\(bu
-Commands like "cd", "directory", etc, execute locally, not on the
-server. Use "ftp cd", "ftp dir", etc, to have them act on the server.
-.TP
-\(bu
-You can have an FTP session and a regular Kermit serial or Telnet
-session open at the same time.
-.TP
-\(bu
-FTP sessions can be fully automated.
-.PP
-Pending publication of the next edition of the manual, the Kermit FTP
-client is thoroughly documented at the Kermit Project website:
-.sp
- http://www.columbia.edu/kermit/ftpclient.html
-.sp
-You also can use HELP FTP and HELP SET FTP to get descriptions of Kermit's
-FTP\(hyrelated commands.
-.PP
-The HTTP client is similar to the FTP one, except you prefix each command
-with HTTP instead of FTP: HTTP OPEN, HTTP GET, HTTP PUT, HTTP CLOSE, etc.
-Type HELP HTTP for details, or visit the to view the manual supplements.
-HTTP connections can be open at the same time as regular serial or Telnet
-connections and FTP connections. So Kermit can manage up to three types
-connections simultaneously.
-.SH INTERNET KERMIT SERVICE
-C\(hyKermit can be configured and run as an Internet service (called IKSD),
-similar to an FTP server (FTPD) except you can (but need not) interact with
-it directly, plus it does a lot more than an FTP server can do. The TCP
-port for IKSD is 1649. It uses Telnet protocol. C\(hyKermit can be an Internet
-Kermit Server, or it can be a client of an IKSD. You can make connections
-from C\(hyKermit to an IKSD with any of the following commands:
-.sp
-.nf
- telnet foo.bar.edu 1649
- telnet foo.bar.edu kermit ; if "kermit" is listed in /etc/services
- iksd foo.bar.edu
-.fi
-.sp
-The IKSD command is equivalent to a TELNET command specifying port 1649.
-For more information about making and using connections to an IKSD, see:
-.sp
- http://www.columbia.edu/kermit/cuiksd.html
-.sp
-You can run an Internet Kermit Service on your own computer too (if you are
-the system administrator). For instructions, see:
-.sp
- http://www.columbia.edu/kermit/iksd.html
-.SH SECURITY
-All of C\(hyKermit's built\(hyin TCP/IP networking methods (Telnet, Rlogin, IKSD,
-FTP, and HTTP) can be secured by one or more of the following IETF\(hyapproved
-methods:
-.PP
-\(bu MIT Kerberos IV
-.br
-\(bu MIT Kerberos V
-.br
-\(bu SSL/TLS
-.br
-\(bu Stanford SRP
-.PP
-For complete instructions see:
-.PP
- http://www.columbia.edu/kermit/security.html
-.PP
-And as noted previously, you can also make SSH connections with C\(hyKermit if
-you already have an SSH client installed.
-.SH ALTERNATIVE COMMAND\(hyLINE PERSONALITIES
-When invoked as "kermit" or any other name besides "ftp" or "telnet",
-C\(hyKermit has the command\(hyline options described above in the OPTIONS
-section. However, if you invoke C\(hyKermit as "telnet" or "ftp", it changes
-its command\(hyline personality to match. This can be done (among other ways)
-with symbolic links (symlinks). For example, if you want C\(hyKermit to be
-your regular Telnet client, or the Telnet helper of your Web browser, you
-can create a link like the following in a directory that lies in your PATH
-ahead of the regular telnet program:
-.sp
- ln \-s /usr/local/bin/kermit telnet
-.sp
-Now when you give a "telnet" command, you are invoking Kermit instead, but
-with its Telnet command\(hyline personality so, for example:
-.sp
- telnet xyzcorp.com
-.sp
-Makes a Telnet connection to xyzcorp.com, and Kermit exits automatically
-when the connection is closed (just like the regular Telnet client). Type
-"telnet \-h" to get a list of Kermit's Telnet\(hypersonality command\(hyline
-options, which are intended to be as compatible as possible with the
-regular Telnet client.
-.PP
-Similarly for FTP:
-.sp
- ln \-s /usr/local/bin/kermit ftp
-.sp
-And now type "ftp \-h" to see its command\(hyline options, and command lines
-just like you would give your regular FTP client:
-.sp
- ftp xyzcorp.com
-.sp
-but with additional options allowing an entire session to be specified on
-the command line. Finally, if Kermit's
-first command\(hyline option is a Telnet, FTP, IKSD, or HTTP URL, Kermit
-automatically makes the appropriate kind of connection and, if indicated by
-the URL, takes the desired action:
-.TP
-kermit telnet:xyzcorp.com
-Opens a Telnet session
-.TP
-kermit telnet://olga@xyzcorp.com
-Ditto for user olga
-.TP
-kermit ftp://olga@xyzcorp.com/public/oofa.zip
-Downloads a file
-.TP
-kermit kermit://kermit.columbia.edu/kermit/f/READ.ME
-Ditto for IKSD
-.TP
-kermit iksd://kermit.columbia.edu/kermit/f/READ.ME

-.SH LICENSE
-C\(hyKermit has an unusual license, but a fair and sensible one since the
-Kermit Project must support itself out of revenue: it's not a BSD license,
-not GPL, not Artistic, not commercial, not shareware, not freeware. It can
-be summed up like this: if you want C\(hyKermit for your own use, you can
-download and use it without cost or license (but we'd appreciate it if you
-would purchase the manual). But if you want to sell C\(hyKermit or bundle it
-with a product or otherwise distribute it in a commercial setting EXCEPT
-WITH AN OPEN\(hySOURCE OPERATING SYSTEM DISTRIBUTION such as Linux, FreeBSD,
-NetBSD, or OpenBSD, you must license it. To see the complete license, give
-the LICENSE command at the prompt, or see the COPYING.TXT file distributed

-C-KERMIT 8.0 UNIX MANUAL PAGE AND TUTORIAL
-
- Frank da Cruz, Christine M. Gianone
- [1]The Kermit Project, [2]Columbia University
-
- [ [3]PDF version ] [ [4]Nroff version ]
-
- This document is intended to give the beginner sufficient
- information to make basic (if not advanced) use of C-Kermit 8.0.
- Although it might be rather long for a Unix manual page (about 1600
- lines), it's still far shorter than the C-Kermit manual, which
- should be consulted for advanced topics such as customization,
- character-sets, scripting, etc. We also attempt to provide a clear
- structural overview of C-Kermit's many capabilities, functional
- areas, states, and modes and their interrelation, that should be
- helpful to beginners and veterans alike, as well as to those
- upgrading to the new release.
-
- Most recent update: 24 October 2002

- DESCRIPTION [ [23]Top ] [ [24]Contents ] [ [25]Next ]
-
- [26]C-Kermit is an all-purpose communications software package from
- the [27]Kermit Project at [28]Columbia University that:
-
- * Is portable to many platforms, Unix and non-Unix alike.
- * Can make both serial and network connections.
- * Can conduct interactive terminal sessions over its connection.
- * Can transfer text or binary files over the same connection.
- * Can convert text-file character sets in terminal mode or file
- transfer.
- * Is customizable in every aspect of its operation.
-
- C-Kermit is a modem program, a Telnet client, an Rlogin client, an FTP
- client, an HTTP client, and on selected platforms, also an X.25
- client. It can make its own secure Internet connections using
- IETF-approved security methods including Kerberos IV, Kerberos V,
- SSL/TLS, and SRP and it can also make SSH (Secure Shell) connections
- through your external SSH client application. It can be the far-end
- file-transfer or client/server partner of your desktop Kermit client.
- It can also accept incoming dialed and network connections. It can
- even be installed as an Internet service on its own standard TCP
- socket, 1649 [[29]RFC2839, [30]RFC2840].
-
- And perhaps most important, everything you can do "by hand"
- (interactively) with C-Kermit, can be "scripted" (automated) using its
- built-in cross-platform transport-independent script programming
- language, which happens to be identical to its interactive command
- language.
-
- This manual page offers an overview of C-Kermit 8.0 for Unix ("Unix"
- is an operating system family that includes AIX, DG/UX, FreeBSD,
- HP-UX, IRIX, Linux, Mac OS X, NetBSD, OpenBSD, Open Server, Open Unix,
- QNX, Solaris, SunOS, System V R3, System V R4, Tru64 Unix, Unixware,
- Xenix, and many others). For thorough coverage, please consult the
- published C-Kermit manual and supplements (see [31]DOCUMENTATION
- below). For further information about C-Kermit, Kermit software for
- other platforms, and Kermit manuals, visit the Kermit Project website:
-
- [32]http://www.columbia.edu/kermit/
-
- This is a longer-than-average manual page, and yet it barely scratches
- the surface. Don't be daunted. C-Kermit is a large and complex
- package, evolving over decades of practice and experience, but that
- doesn't mean it's hard to learn or use. Its most commonly used
- functions are explained here with pointers to additional information
- elsewhere.

-
- SYNOPSIS [ [36]Top ] [ [37]Contents ] [ [38]Next ] [ [39]Previous ]
-
- Usage: kermit [filename] [-x arg [-x arg]...[-yyy]..] [ {=,--,+} text
- ] ]
- Or: kermit URL
-
- * -x is an option requiring an argument;
- * -y is an option with no argument.
-
- If the first command-line argument is the name of a file,
- interactive-mode commands are executed from the file. The '=' (or
- "--") argument tells Kermit not to parse the remainder of the command
- line, but to make the words following '=' available as \%1, \%2, ...
- \%9. The "+" argument is like "=" but for use in "kerbang scripts"
- (explained [40]below). A second command-line format allows the one and
- only argument to be a [41]Telnet, FTP, HTTP, or IKSD URL.
-
- Order of execution:
-
- 1. [42]The command file (if any).
- 2. [43]The initialization file, if any, unless suppressed with -Y.
- 3. [44]The customization file (if it is executed by the
- initialization file).
- 4. [45]The command-line URL (if any, and if so, execution stops
- here).
- 5. [46]Command-line options (if any).
- 6. [47]Interactive commands.
-
- Some command-line options can cause actions (such as -s to send a
- file); others just set parameters. If any action options are included
- on the command line, Kermit exits when finished unless also given the
- -S ("stay") option. If no action options are given, no initialization
- or command files contained an EXIT or QUIT command, and no fatal
- errors occurred, Kermit issues its prompt and waits for you to type
- commands.
-
- Bear in mind that C-Kermit can be built with selected features
- disabled, and also that certain features are not available on all
- platforms. For example, C-Kermit can't be built with TCP/IP support
- on a platform that does not have TCP/IP header files and libraries
- (and even if Kermit does include TCP/IP support, it can't be used
- to make TCP/IP connections on a computer that does not have a
- TCP/IP stack installed). If your version of C-Kermit lacks a
- feature mentioned here, use its SHOW FEATURES command to see what
- might have been excluded.
-
- C-Kermit has three kinds of commands: regular single-letter
- command-line options, extended-format command-line options, and
- interactive commands.

-
- OPTIONS [ [51]Top ] [ [52]Contents ] [ [53]Next ] [ [54]Previous ]
-
- Like most Unix commands, C-Kermit can be be given options on the
- command line. But C-Kermit also can be used interactively by giving it
- [55]commands composed of words, which are more intuitive than cryptic
- command-line options, and more flexible too. In other words, you don't
- have to use C-Kermit's command-line options, but they are available if
- you want to. (By the same token, you don't have to use its interactive
- commands either -- you can use either or both in any combination.)
-
- C-Kermit is generally installed in the PATH as "kermit", and therefore
- is invoked by typing the word "kermit" (lowercase) at the shell
- prompt, and then pressing the Return or Enter key. If you wish to
- include command-line options, put them after the word "kermit" but
- before pressing Return or Enter, separated by spaces, for example:
-
- $ kermit -s ckermit.tar.gz
-
- ('$' is the shell prompt; "kermit -s ckermit.tar.gz" is what you type,
- followed by Return or Enter.)
-
- Here is a list of C-Kermit's single-letter command-line options, which
- start with a single dash (-), in ASCII ("alphabetical") order.
- Alphabetic case is significant (-A is not the same as -a). The Action?
- column contains Y for action options and N for non-action options.
- Option Action? Description
- -0 N (digit zero) 100% transparent Connect state for "in-the-middle"
- operation: 8 bits, no parity, no escape character, everything passes
- through.
- -8 N (digit eight) Connection is 8-bit clean (this is the default in
- C-Kermit 8.0). Equivalent to the EIGHTBIT command, which in turn is a
- shortcut for SET TERMINAL BYTESIZE 8, SET COMMAND BYTESIZE 8, SET
- PARITY NONE.
- -9 arg N (digit nine) Make a connection to an FTP server. Equivalent
- to the FTP OPEN command.
- Argument: IP-address-or-hostname[:optional-TCP-port].
- NOTE: C-Kermit also has a separate FTP command-line personality, with
- regular FTP-like command-line syntax. [56]More about this below.
- -A N Kermit is to be started as an Internet service (IKSD) (only from
- inetd.conf).
- -B N Kermit is running in Batch or Background (no controlling
- terminal). To be used in case Kermit doesn't automatically sense its
- background status. Equivalent to the SET BACKGROUND ON command.
- -C arg N Interactive-mode Commands to be executed.
- Argument: Commands separated by commas, list in doublequotes.
- -D arg N Delay before starting to send in Remote mode. Equivalent to
- the SET DELAY command.
- Argument: Number of seconds.
- -E N Exit automatically when connection closes. Equivalent to SET EXIT
- ON-DISCONNECT ON.
- -F arg N Use an open TCP connection.
- Argument: Numeric file descriptor of open TCP connection.
- Also see: -j, -J.
- -G arg Y Get file(s) from server, send contents to standard output,
- which normally would be piped to another process.
- Argument: Remote file specification, in quotes if it contains
- metacharacters.
- Also see: -g, -k.
- -H N Suppress program startup Herald and greeting.
- -I N Tell Kermit it has a reliable connection, to force streaming to
- be used where it normally would not be. Equivalent to the SET RELIABLE
- ON command.
- -J arg N "Be like Telnet." Like -j but implies -E.
- Argument: IP hostname/address optionally followed by service.
- NOTE: C-Kermit also has a separate Telnet command-line personality,
- with regular Telnet-like command-line syntax. [57]More about this
- below.
- -L N Recursive directory descent for files in -s option.
- -M arg N My user name (for use with Telnet, Rlogin, FTP, etc).
- Equivalent to the SET LOGIN USER command.
- Argument: Username string.
- -O Y (Uppercase letter O) Be a server for One command only. Also see:
- -x.
- -P N Don't convert file (Path) names of transferred files. Equivalent
- to SET FILE NAMES LITERAL.
- -Q N Quick Kermit protocol settings. Equivalent to the FAST command.
- This is the default in C-Kermit 7.0 and later.
- -R N Remote-only (this just makes IF REMOTE true).
- -S N Stay (enter command parser after action options).
- -T N Force Text mode for file transfer; implies -V. Equivalent to SET
- TRANSFER MODE MANUAL, SET FILE TYPE TEXT.
- -V N Disable automatic per-file text/binary switching. Equivalent to
- SET TRANSFER MODE MANUAL.
- -Y N Skip (don't execute) the initialization file.
- -a arg N As-name for file(s) in -s, -r, or -g.
- Argument: As-name string (alternative filename). When receiving files,
- this can be a directory name.
- -b arg N Speed for serial device. Equivalent to SET SPEED.
- Argument: Numeric Bits per second for serial connections.
- -c Y Enter Connect state before transferring files.
- -d N Create a debug.log file with detailed debugging information (a
- second -d adds timestamps). Equivalent to LOG DEBUG but takes effect
- sooner.
- -e arg N Maximum length for incoming Kermit file-transfer packets.
- Equivalent to SET RECEIVE PACKET-LENGTH.
- Argument: Length in bytes.
- -f Y Send a FINISH command to a Kermit server.
- -g arg N Get file(s) from a Kermit server.
- Argument: File specification on other computer, in quotes if it
- contains metacharacters. Equivalent to GET.
- Also see: -a, -G, -r.
- -h Y Print Help text for single-letter command-line options (pipe thru
- 'more' to prevent scrolling).
- -i N Force binary (Image) mode for file transfer; implies -V.
- Equivalent to SET TRANSFER MODE MANUAL, SET FILE TYPE BINARY.
- -j arg N Make a TCP/IP connection.
- Argument: IP host name/address and optional service name or number.
- Equivalent to the TELNET command.
- Also see: -J, -F.
- -k Y Receive file(s) to standard output, which normally would be piped
- to another process.
- Also see: -r, -G.
- -l arg N (Lowercase letter L) Make a connection on the given serial
- communications device. Equivalent to the SET LINE (SET PORT) command.
- Argument: Serial device name, e.g. /dev/ttyS0.
- -m arg N Modem type for use with the -l device. Equivalent to the SET
- MODEM TYPE command.
- Argument: Modem name as in SET MODEM TYPE command, e.g. "usrobotics".
- -n Y Enter Connect state after transferring files (historical).
- -p arg N Parity. Equivalent to the SET PARITY command.
- Argument: One of the following: e(ven), o(dd), m(ark), n(one),
- s(pace).
- -q N Quiet (suppress most messages). Equivalent to SET QUIET ON.
- -r Y Receive file(s). Equivalent to the RECEIVE command.
- Argument: (none, but see -a)
- -s arg N Send file(s).
- Argument: One or more local file specifications. Equivalent to the
- SEND command.
- Also see: -a.
- -t N (Historical) Xon (Ctrl-Q) Turnaround character for half-duplex
- connections (used on serial linemode connections to old mainframes).
- Equivalent to SET DUPLEX HALF, SET HANDSHAKE XON.
- -v arg N Window size for Kermit protocol (ignored when streaming).
- Equivalanet to SET WINDOW-SIZE.
- Argument: Number, 1 to 32.
- -w N Incoming files Write over existing files. Equivalent to SET FILE
- COLLISION OVERWRITE.
- -x Y Enter server mode. Equivalent to the SERVER command. Also see:
- -O.
- -y arg N Alternative initialization file.
- Argument: Filename.
- -z N Force foreground behavior. To be used in case Kermit doesn't
- automatically sense its foreground status. Equivalent to the SET
- BACKGROUND OFF command.
-
- Extended command-line options (necessary because single-letter ones
- are about used up) start with two dashes (--), with words rather than
- single letters as option names. If an extended option takes an
- argument, it is separated from the option word by a colon (:).
- Extended options include:
- Option Description
- --bannerfile:filename File to display upon startup or IKSD login.
- --cdfile:filename File to be sent for display to the client when
- server changes directory (filename is relative to the changed-to
- directory).
- --cdmessage:{on,off} Enable/disable the server CD message feature.
- --help Prints usage message for extended options.
- --helpfile:filename Designates a file containing custom text to
- replace the top-level HELP command.
- --nointerrupts Disables keyboard interrupts.
- --noperms Disables the Kermit protocol file Permissions attribute, to
- prevent transmission of file permissions (protection) from sender to
- receiver.
-
- Plus several other [58]IKSD-Only options.
-
- See the [59]file-transfer section for examples of command-line
- invocation.

- COMMAND LANGUAGE [ [60]Top ] [ [61]Contents ] [ [62]Next ] [ [63]Previous ]
-
- * [64]Command Files, Macros, and Scripts
- * [65]Command List
-
- C-Kermit's interactive command language is the subject of a
- [66]622-page book and another several hundred pages of updates, far
- too much for a manual page. But it's not hard to get started. At the
- shell prompt, just type "kermit" to get C-Kermit's interactive command
- prompt:
-
- $ kermit
- (/current/directory) C-Kermit>
-
- Begin by typing "help" (and then press the Return or Enter key) for a
- top-level overview, read it, and go from there. Your second command
- should probably be "intro" (introduction). Note the prompt shows your
- current directory (unless you tell Kermit to prompt you with something
- else).
-
- Interactive commands are composed mainly of regular English words,
- usually in the form of imperative sentences, such as:
-
- send oofa.txt
-
- which tells Kermit to send (transfer) the file whose name is oofa.txt,
- or:
-
- set transfer mode automatic
-
- which sets Kermit's "transfer mode" to "automatic" (whatever that
- means).
-
- While typing commands, you can abbreviate, ask for help (by pressing
- the "?" key anywhere in a command), complete keywords or filenames
- (with the Tab or Esc key), and edit your typing with Backspace or
- Delete, Ctrl-W, Ctrl-U, etc. You can also recall previous commands,
- save your command history, and who knows what else. Give the INTRO
- command for details.
-
- C-Kermit has hundreds of commands, and they can be issued in infinite
- variety and combinations, including commands for:
-
- * Making connections (SET LINE, DIAL, TELNET, SSH, FTP, CONNECT,
- ...)
- * Breaking connections (HANGUP, CLOSE)
- * Transferring files (SEND, GET, RECEIVE, MOVE, RESEND, ...)
- * Establishing preferences (SET)
- * Displaying preferences (SHOW)
- * Managing local files (CD, DELETE, MKDIR, DIRECTORY, RENAME, TYPE,
- ...)
- * Managing remote files (RCD, RDEL, RMKDIR, RDIR, ...)
- * Using local files (FOPEN, FCLOSE, FREAD, FWRITE)
- * Programming (TAKE, DEFINE, IF, FOR, WHILE, SWITCH, DECLARE, ...)
- * Interacting with the user (ECHO, ASK, ...)
- * Interacting with a remote computer (INPUT, OUTPUT, ...)
- * Interacting with local programs (RUN, EXEC, PTY, ...)
- * Logging things (LOG SESSION, LOG PACKETS, LOG DEBUG, ...)
-
- And of course QUIT or EXIT to get out and HELP to get help, and for
- programmers: loops, decision making, variables, arrays, associative
- arrays, integer and floating point arithmetic, macros, built-in and
- user-defined functions, string manipulation, pattern matching, block
- structure, scoping, recursion, and all the rest. To get a list of all
- C-Kermit's commands, type a question mark (?) at the prompt. To get a
- description of any command, type HELP followed by the name of the
- command, for example:
-
- help send
-
- The command interruption character is Ctrl-C (hold down the Ctrl key
- and press the C key).
-
- The command language "escape character", used to introduce variable
- names, function invocations, and so on, is backslash (\). If you need
- to include a literal backslash in a command, type two of them, e.g.:
-
- get c:\\k95\\k95custom.ini
-
- Command Files, Macros, and Scripts
-
- A file containing Kermit commands is called a Kermit command file or
- Kermit script. It can be executed with Kermit's TAKE command:
-
- (/current/dir) C-Kermit> take commandfile
-
- (where "commandfile" is the name of the command file). Please don't
- pipe a command file into Kermit's standard input (which might or might
- not work); if you have Kermit commands in a file, tell Kermit to TAKE
- the file.
-
- In Unix only, a Kermit command file can also be executed directly by
- including a "kerbang" line as the first line of the file:
-
- #!/usr/local/bin/kermit +
-
- That is, a top line that starts with "#!", followed immediately by the
- full path of the Kermit executable, and then, if the Kermit script is
- to be given arguments on the command line, a space and a plus sign.
- The script file must also have execute permission:
-
- chmod +x commandfile
-
- Except for the " +" part, this is exactly the same as you would do for
- a shell script, a Perl script, etc. Here's a simple but useless
- example script that regurgitates its arguments (up to three of them):
-
- #!/usr/local/bin/kermit +
- if defined \%1 echo "Argument 1: \%1"
- if defined \%2 echo "Argument 2: \%2"
- if defined \%3 echo "Argument 3: \%3"
- if defined \%4 echo "etc..."
- exit
-
- If this file is stored in your current directory as "commandfile",
- then:
-
- ./commandfile one two three four five
-
- prints:
-
- Argument 1: one
- Argument 2: two
- Argument 3: three
- etc...
-
- This illustrates the basic structure of a standalone Kermit script:
- the "kerbang line", then some commands. It should end with "exit"
- unless you want the Kermit prompt to appear when it is finished. \%1
- is the first argument, \%2 the second, and so on.
-
- You can also create your own commands by defining named macros
- composed of other Kermit commands (or macros). Here's a simple
- example:
-
- define mydial {
- set modem type usrobotics
- set port /dev/ttyS0
- if fail end 1
- set speed 57600
- dial \%1
- if success connect
- }
-
- This shows how you can combine many commands into one command,
- "mydial" in this case (you can use any name you like, provided it does
- not clash with the name of a built-in command). When this macro
- definition is in effect, you can type commands like:
-
- mydial 7654321
-
- and it executes all the commands in macro definition, substituting the
- first operand ("7654321") for the formal parameter ("\%1") in the
- definition. This saves you from having to type lots of commands every
- time you want to make a modem call.
-
- One way to have the macro definition in effect is to type the
- definition at the Kermit prompt. Another way is to store the
- definition in a file and TAKE the file. If you want the the definition
- to be in effect automatically every time you start Kermit, put the
- definition in your initialization or customization file (explained
- [67]below).
-
- Here's a somewhat more ambitious example:
-
- define mydelete {
- local trash
- assign trash \v(home)trashcan/
- if not defined \%1 end 1 "Delete what?"
- if wild \%1 end 1 "Deleting multiple files is too scary"
- if not exist \%1 end 1 "I can't find \%1"
- if not directory \m(trash) {
- mkdir \m(trash)
- if fail end 1 "No trash can"
- }
- rename /list \%1 \m(trash)
- }
- define myundelete {
- local trash
- assign trash \v(home)trashcan/
- if not defined \%1 end 1 "Undelete what?"
- if wild \%1 end 1 "Undeleting multiple files is too hard"
- if not directory \m(trash) end 1 "No trash can"
- if not exist \m(trash)\%1 end 1 "I can't find \%1 in trash can"
- rename /list \m(trash)\%1 .
- }
-
- These macros are not exactly production quality (they don't handle
- filenames that include path segments, they don't handle multiple
- files, etc), but you get the idea: you can pass arguments to macros,
- they can check them and make other kinds of decisions, and the
- commands themselves are relatively intuitive and intelligible.
-
- If you put the above lines into your initialization or customization
- file, you'll have MYDELETE and MYUNDELETE commands available every
- time you start Kermit, at least as long as you don't suppress
- execution of the initialization file. (Exercise for the reader: Make
- these macros generally useful: remove limitations, add trashcan
- display, browsing, emptying, etc.)
-
- Kerbang scripts execute without the initialization file. This to keep
- them portable and also to make them start faster. If you want to write
- Kerbang scripts that depend on the initialization file, include the
- command
-
- take \v(home).kermrc
-
- at the desired spot in the script. By the way, \v(xxx) is a built-in
- variable (xxx is the variable name, "home" in this case). To see what
- built-in variables are available, type "show variables" at the
- C-Kermit prompt. To see what else you can show, type "show ?". \m(xxx)
- is a user defined variable (strictly speaking, it is a macro used as a
- variable).
-
- Command List
-
- C-Kermit has more than 200 top-level commands, and some of these, such
- as SET, branch off into hundreds of subcommands of their own, so it's
- not practical to describe them all here. Instead, here's a concise
- list of the most commonly used top-level commands, grouped by
- category. To learn about each command, type "help" followed by the
- command name, e.g. "help set". Terms such as Command state and Connect
- state are explained in subsequent sections.
-
- Optional fields are shown in [ italicized brackets ]. filename means
- the name of a single file. filespec means a file specification that is
- allowed to contain wildcard characters like '*' to match groups of
- files. options are (optional) switches like /PAGE, /NOPAGE, /QUIET,
- etc, listed in the HELP text for each command. Example:
-
- send /recursive /larger:10000 /after:-1week /except:*.txt *
-
- which can be read as "send all the files in this directory and all the
- ones underneath it that are larger than 10000 bytes, no more than one
- week old, and whose names don't end with ".txt".

- Many of Kermit's commands have synonyms, variants, relatives, and so
- on. For example, MSEND is a version of SEND that accepts a list of
- file specifications to be sent, rather than just one file
- specification, and MPUT is a synonym of MSEND. MOVE means to SEND and
- then DELETE the source file if successful. MMOVE is like MOVE, but
- accepts a list of filespecs, and so on. These are described in the
- [70]full documentation.

- This is called menu on demand: you get a menu when you want one, but
- menus are not forced on you even when know what you're doing. Note
- that you can also abbreviate most keywords, and you can complete them
- with the Tab or Esc key. Also note that ? works for filenames too, and
- that you can use it in the middle of a keyword or filename, not just
- at the beginning. For example, "send x?" lists all the files in the
- current directory whose names start with 'x'.

-
- INITIALIZATION FILE [ [74]Top ] [ [75]Contents ] [ [76]Next ] [ [77]Previous
- ]
-
- In its default configuration, C-Kermit executes commands from a file
- called .kermrc in your home directory when it starts, unless it is
- given the -Y or -y command-line option. Custom configurations might
- substitute a shared system-wide initialization file. The SHOW FILE
- command tells what initialization file, if any, was used. The standard
- initialization file "chains" to an individual customization file,
- .mykermc, in the home directory, in which each user can establish
- her/his own preferences, define macros, and so on.
-
- Since execution of the initialization file (at least the standard one)
- makes C-Kermit take longer to start, it might be better not to have an
- initialization file, especially now that Kermit's default startup
- configuration is well attuned to modern computing and networking -- in
- other words, you no longer have do anything special to make Kermit
- transfers go fast. So instead of having an initialization file that is
- executed every time Kermit starts, you might consider making one or
- more kerbang scripts (with names other that .kermrc) that do NOT
- include an "exit" command, and invoke those when you need the
- settings, macro definitions, and/or scripted actions they contain, and
- invoke C-Kermit directly when you don't.
-
- To put it another way... We still distribute the standard
- initialization file since it's featured in the manual and backwards
- compatibility is important to us. But there's no harm in not using it
- if you don't need the stuff that's in it (services directory, dialing
- directory, network directory, and associated macro definitions). On
- the other hand, if there are settings or macros you want in effect
- EVERY time you use Kermit, the initialization file (or the
- customization file it chains to) is the place to put them, because
- that's the only place Kermit looks for them automatically each time
- you start it.

-
- MODES OF OPERATION [ [81]Top ] [ [82]Contents ] [ [83]Next ] [ [84]Previous ]
-
- Kermit is said to be in Local mode if it has made a connection to
- another computer, e.g. by dialing it or establishing a Telnet
- connection to it. The other computer is remote, so if you start
- another copy of Kermit on the remote computer, it is said to be in
- Remote mode (as long as it has not made any connections of its own).
- The local Kermit communicates over the communications device or
- network connection, acting as a conduit between the the remote
- computer and your keyboard and screen. The remote Kermit is the
- file-transfer partner to the local Kermit and communicates only
- through its standard input and output.
-
- At any moment, a Kermit program can be in any of the following states.
- It's important to know what they are and how to change from one to the
- other.
-
- Command state
-
- In this state, Kermit reads commands from:
-
- + Your keyboard; or:
- + A file, or:
- + A macro definition.
-
- You can exit from Command state back to Unix with the EXIT or
- QUIT command (same thing). You can enter Connect state with any
- of various commands (CONNECT, DIAL, TELNET, etc). You can enter
- file transfer state with commands like SEND, RECEIVE, and GET.
- You can enter Server state with the SERVER command. The TAKE
- command tells Kermit to read and execute commands from a file.
- The (perhaps implied) DO command tells Kermit to read and
- execute commands from a macro definition. While in Command
- state, you can interrupt any command, macro, or command file by
- typing Ctrl-C (hold down the Ctrl key and press the C key);
- this normally brings you back to the prompt.
-
- Shell state
-
- You can invoke an inferior shell or external command from the
- Kermit command prompt by using the PUSH, RUN (!), EDIT, or
- BROWSE command. While the inferior shell or command is active,
- Kermit is suspended and does nothing. Return to Kermit Command
- state by exiting from the inferior shell or application.
-
- Connect state
-
- In this state, which can be entered only when in Local mode
- (i.e. when Kermit has made a connection to another computer),
- Kermit is acting as a terminal to the remote computer. Your
- keystrokes are sent to the remote computer and characters that
- arrive over the communication connection are displayed on your
- screen. This state is entered when you give a CONNECT, DIAL,
- TELNET, RLOGIN, or IKSD command. You can return to command
- state by logging out of the remote computer, or by typing:
-
- Ctrl-\c
-
- That is: Hold down the Ctrl key and press the backslash key,
- then let go of the Ctrl key and press the C key. This is called
- escaping back. Certain other escape-level commands are also
- provided; type Ctrl-\? for a list. For example, you can enter
- Shell state with:
-
- Ctrl-\!
-
- To send a Ctrl-\ to the host while in Connect state, type two
- of them in a row. See HELP CONNECT and HELP SET ESCAPE for more
- info.
-
- Local file-transfer state
-
- In this state, Kermit is sending packets back and forth with
- the other computer in order to transfer a file or accomplish
- some other file-related task. And at the same time, it is
- displaying its progress on your screen and watching your
- keyboard for interruptions. In this state, the following
- single-keystroke commands are accepted:
-
- X Interrupt the current file and go on to the next (if any).
- Z Interrupt the current file and skip all the rest.
- E Like Z but uses a "stronger" protocol (use if X or Z don't
- work).
- Ctrl-C Interrupt file-transfer mode (use if Z or E don't
- work).
-
- Kermit returns to its previous state (Command or Connect) when
- the transfer is complete or when interrupted successfully by X,
- Z, E, or Ctrl-C (hold down the Ctrl key and press the C key).
-
- Remote file-transfer state
-
- In this state, Kermit is exchanging file-transfer packets with
- its local partner over its standard i/o. It leaves this state
- automatically when the transfer is complete. In case you find
- your local Kermit in Connect state and the remote one in
- File-transfer state (in which it seems to ignore your
- keystrokes), you can usually return it to command state by
- typing three Ctrl-C's in a row. If that doesn't work, return
- your local Kermit to Command state (Ctrl-\ C) and type
- "e-packet" and then press the Return or Enter key; this forces
- a fatal Kermit protocol error.
-
- Remote Server state
-
- This is like Remote File-transfer state, except it never
- returns automatically to Command state. Rather, it awaits
- further instructions from the client program; that is, from
- your Local Kermit program. You can return the Remote Server to
- its previous state by issuing a "finish" command to the client,
- or if you are in Connect state, by typing three Ctrl-C's in a
- row. You can tell the server job to log out and break the
- connection by issuing a "bye" command to the client.
-
- Local Server state
-
- Like Remote-Server state, but in local mode, and therefore with
- its file-transfer display showing, and listening for single-key
- commands, as in Local File-transfer state. Usually this state
- is entered automatically when a remote Kermit program gives a
- GET command.
-
- C-Kermit, Kermit 95, and MS-DOS Kermit all can switch automatically
- from Connect state to Local File-transfer state when you initiate a
- file transfer from the remote computer by starting Kermit and telling
- it to send or get a file, in which case, Connect state is
- automatically resumed after the file transfer is finished.
-
- Note that C-Kermit is not a terminal emulator. It is a communications
- application that you run in a terminal window (e.g. console or Xterm).
- The specific emulation, such as VT100, VT220, Linux Console, or Xterm,
- is provided by the terminal window in which you are running C-Kermit.
- Kermit 95 and MS-DOS Kermit, on the other hand, are true terminal
- emulators. Why is C-Kermit not a terminal emulator? [85]CLICK HERE to
- read about it.

-
- MAKING CONNECTIONS [ [89]Top ] [ [90]Contents ] [ [91]Next ] [ [92]Previous ]
-
- Here is how to make different kinds of connections using interactive
- Kermit commands (as noted above, you can also make connections with
- command-line options). Note that you don't have to make connections
- with Kermit. It can also be used on the far end of a connection as the
- remote file transfer and management partner of your local
- communications software.
-
- Making a Telnet Connection
-
- At the C-Kermit command prompt, simply type:
-
- telnet foo.bar.com ; Substitute desired host name or address.
- telnet xyzcorp.com 3000 ; You can also include a port number.
-
- If the connection is successful, Kermit automically enters
- Connect state. When you logout from the remote host, Kermit
- automatically returns to its prompt. More info: HELP TELNET,
- HELP SET TELNET, HELP SET TELOPT. Also see the [93]IKSD section
- below.
-
- Making an Rlogin connection
-
- This is just like Telnet, except you have to be root to do it
- because Rlogin uses a privileged TCP port:
-
- rlogin foo.bar.com ; Substitute desired host name or address.
-
- More info: HELP RLOGIN.
-
- Making an SSH Connection
-
- Unlike Telnet and Rlogin, SSH connections are not built-in, but
- handled by running your external SSH client through a
- pseudoterminal. Using C-Kermit to control the SSH client gives
- you all of Kermit's features (file transfer, character-set
- conversion, scripting, etc) over SSH.
-
- ssh foo.bar.com ; Substitute desired host name or address.
-
- More info: HELP SSH, HELP SET SSH.
-
- Dialing with a Modem
-
- If it's an external modem, make sure it is connected to a
- usable serial port on your computer with a regular
- (straight-through) modem cable, and to the telephone jack with
- a telephone cable, and that it's turned on. Then use these
- commands:
-
- set modem type usrobotics ; Or other supported type
- set line /dev/ttyS0 ; Specify device name
- set speed 57600 ; Or other desired speed
- set flow rts/cts ; Most modern modems support this
- set dial method tone ; (or pulse)
- dial 7654321 ; Dial the desired number
-
- Type "set modem type ?" for a list of supported modem types. If
- you omit the SET MODEM TYPE command, the default type is
- "generic-high-speed", which should work for most modern
- AT-command-set modems. If the line is busy, Kermit redials
- automatically. If the call does not succeed, use "set dial
- display on" and try it again to watch what happens. If the call
- succeeds, Kermit enters Connect state automatically and returns
- to its prompt automatically when you log out from the remote
- computer or the connection is otherwise lost.
-
- You can also dial from a modem that is accessible by Telnet,
- e.g. to a reverse terminal server. In this case the command
- sequence is:
-
- set host ts.xxx.com 2000 ; Terminal-server and port
- set modem type usrobotics ; Or other supported type
- set dial method tone ; (or pulse)
- dial 7654321 ; Dial the desired number
-
- If the terminal server supports the Telnet Com Port Option,
- [94]RFC 2217, you can also give serial-port related commands
- such as SET SPEED, SET PARITY, and so on, and Kermit relays
- them to the terminal server using the protocol specified in the
- RFC.
-
- More info: HELP SET MODEM, HELP SET LINE, HELP SET SPEED, HELP
- SET FLOW, HELP DIAL, HELP SET DIAL, HELP SET MODEM, HELP SET
- CARRIER-WATCH, SHOW COMMUNICATIONS, SHOW MODEM, SHOW DIAL.
-
- Direct Serial Port
-
- Connect the two computers, A and B, with a null modem cable (or
- two modem cables interconnected with a null-modem adapter or
- modem eliminator). From Computer A:
-
- set modem type none ; There is no modem
- set line /dev/ttyS0 ; Specify device name
- set carrier-watch off ; If DTR and CD are not cross-connected
- set speed 57600 ; Or other desired speed
- set flow rts/cts ; If RTS and CTS are cross-connected
- set flow xon/xoff ; If you can't use RTS/CTS
- set parity even ; (or "mark" or "space", if necessary)
- set stop-bits 2 ; (rarely necessary)
- connect ; Enter Connect (terminal) state
-
- This assumes Computer B is set up to let you log in. If it
- isn't, you can run a copy of Kermit on Computer B and follow
- approximately the same directions. More info: As above plus
- HELP CONNECT.
-
- With modems or direct serial connections, you might also have to "set
- parity even" (or "mark" or "space") if it's a 7-bit connection.
-
- Of the connection types listed above, only one can be open at a time.
- However, any one of these can be open concurrently with an [95]FTP or
- HTTP session. Each connection type can be customized to any desired
- degree, scripted, logged, you name it. See the manual.
-
- NOTE: On selected platforms, C-Kermit also can make X.25 connections.
- See the manual for details.

- * [108]Non-Kermit File Transfer
-
- There is a [109]widespread and persistent belief that Kermit is a slow
- protocol. This is because, until recently, it used conservative tuning
- by default to make sure file transfers succeeded, rather than failing
- because they overloaded the connection. Some extra commands (or
- command-line options, like -Q) were needed to make it go fast, but
- nobody bothered to find out about them. Also, it takes two to tango:
- most non-Kermit-Project Kermit protocol implementations really ARE
- slow. The best file-transfer partners for C-Kermit are: another copy
- of [110]C-Kermit (7.0 or later) and [111]Kermit 95. These combinations
- work well and they work fast by default. MS-DOS Kermit is good too,
- but you have to tell it to go fast (by giving it the FAST command).
-
- Furthermore, all three of these Kermit programs support "autodownload"
- and "autoupload", meaning that when they are in Connect state and a
- Kermit packet comes in from the remote, they automatically switch into
- file transfer mode.
-
- And plus, C-Kermit and K95 also switch automatically between text and
- binary mode for each file, so there is no need to "set file type
- binary" or "set file type text", or to worry about files being
- corrupted because they were transferred in the wrong mode.
-
- What all of these words add up to is that now, when you use up-to-date
- Kermit software from the Kermit Project, file transfer is not only
- fast, it's ridiculously easy. You barely have to give any commands at
- all.
-
- Downloading Files
-
- Let's say you have [112]Kermit 95, [113]C-Kermit, or
- [114]MS-DOS Kermit on your desktop computer, with a connection
- to a Unix computer that has C-Kermit installed as "kermit". To
- download a file (send it from Unix to your desktop computer),
- just type the following command at your Unix shell prompt:
-
- kermit -s oofa.txt
-
- (where oofa.txt is the filename). If you want to send more than
- one file, you can put as many filenames as you want on the
- command line, and they can be any combination of text and
- binary:
-
- kermit -s oofa.txt oofa.zip oofa.html oofa.tar.gz
-
- and/or you can use wildcards to send groups of files:
-
- kermit -s oofa.*
-
- If you want to send a file under an assumed name, use:
-
- kermit -s friday.txt -a today.txt
-
- This sends the file friday.txt but tells the receiving Kermit
- that its name is today.txt. In all cases, as noted, when the
- file transfer is finished, your desktop Kermit returns
- automatically to Connect state. No worries about escaping back,
- re-connecting, text/binary mode switching. Almost too easy,
- right?
-
- Uploading Files
-
- To upload files (send them from your desktop computer to the
- remote Unix computer) do the same thing, but use the -g (GET)
- option instead of -s:
-
- kermit -g oofa.txt
-
- This causes your local Kermit to enter server mode; then the
- remote Kermit program requests the named file and the local
- Kermit sends it and returns automatically to Connect state when
- done.
-
- If you want to upload multiple files, you have have use shell
- quoting rules, since these aren't local files:
-
- kermit -g "oofa.txt oofa.zip oofa.html oofa.tar.gz"
- kermit -g "oofa.*"
-
- If you want to upload a file but store it under a different
- name, use:
-
- kermit -g friday.txt -a today.txt
-
- Kermit Transfers the Old-Fashioned Way
-
- If your desktop communications software does not support
- autoupload or autodownload, or it does not include Kermit
- server mode, the procedure requires more steps.
-
- To download a file, type:
-
- kermit -s filename
-
- on the host as before, but if nothing happens automatically in
- response to this command, you have to switch your desktop
- communications software into Kermit Receive state. This might
- be done by escaping back using keyboard characters or hot keys
- (Alt-x is typical) and/or with a command (like RECEIVE) or a
- menu. When the file transfer is complete, you have to go back
- to Connect state, Terminal emulation, or whatever terminology
- applies to your desktop communications software.
-
- To upload a file, type:
-
- kermit -r
-
- on the host (rather than "kermit -g"). This tells C-Kermit to
- wait passively for a file to start arriving. Then regain the
- attention of your desktop software (Alt-x or whatever) and
- instruct it to send the desired file(s) with Kermit protocol.
- When the transfer is finished, return to the Connect or
- Terminal screen.
-
- If File Transfer Fails
-
- Although every aspect of Kermit's operation can be finely
- tuned, there are also three short and simple "omnibus tuning"
- commands you can use for troubleshooting:
-
- FAST
- Use fast file-transfer settings. This has been the
- default since C-Kermit 7.0 now that most modern computers
- and connections support it. If transfers fail with fast
- settings, try . . .
-
- CAUTIOUS
- Use cautious but not paranoid settings. File transfers,
- if they work, will go at medium speed. If not, try . . .
-
- ROBUST
- Use the most robust, resilient, conservative, safe, and
- reliable settings. File transfers will almost certainly
- work, but they will be quite slow (of course this is a
- classic tradeoff; ROBUST was C-Kermit's default tuning in
- versions 6.0 and earlier, which made everybody think
- Kermit protocol was slow). If ROBUST doesn't do the
- trick, try again with SET PARITY SPACE first in case it's
- not an 8-bit connection.
-
- Obviously the success and performance of a file transfer also
- depends on C-Kermit's file transfer partner. Up-to-date, real
- [115]Kermit Project partners are recommended because they
- contain the best Kermit protocol implementations and because
- [116]we can support them in case of trouble.
-
- If you still have trouble, consult Chapter 10 of [117]Using
- C-Kermit, or send email to [118]kermit-support@columbia.edu.
-
- Advanced Kermit File-Transfer Features
-
- Obviously there is a lot more to Kermit file transfer,
- including all sorts of interactive commands, preferences,
- options, logging, debugging, troubleshooting, and anything else
- you can imagine but that's what the [119]manual and updates are
- for. Here are a few topics you can explore if you're interested
- by Typing HELP for the listed commands:
-
- Logging transfers:
- LOG TRANSACTIONS (HELP LOG)
-
- Automatic per-file text/binary mode switching:
- SET TRANSFER MODE { AUTOMATIC, MANUAL } (HELP SET
- TRANSFER).
-
- Cross-platform recursive directory tree transfer:
- SEND /RECURSIVE, GET /RECURSIVE (HELP SEND, HELP GET).
-
- File collision options:
- SET FILE COLLISION { OVERWRITE, BACKUP, DISCARD, ... }
- (HELP SET FILE).
-
- Update mode (only transfer files that changed since last time):
- SET FILE COLLISION UPDATE (HELP SET FILE).
-
- Filename selection patterns:
- (HELP WILDCARD).
-
- Flexible file selection:
- SEND (or GET) /BEFORE /AFTER /LARGER /SMALLER /TYPE
- /EXCEPT, ...
-
- Character-set conversion:
- SET { FILE, TRANSFER } CHARACTER-SET, ASSOCIATE, ...
-
- File/Pathname control:
- SET { SEND, RECEIVE } PATHNAMES, SET FILE NAMES.
-
- Atomic file movement:
- SEND (or GET) /DELETE /RENAME /MOVE-TO
-
- Transferring to/from standard i/o of other commands:
- SEND (or GET) /COMMAND
-
- Recovery of interrupted transfer from point of failure:
- RESEND, REGET (HELP RESEND, HELP REGET).
-
- Non-Kermit File Transfer
-
- You can also use C-Kermit to transfer files with FTP or HTTP
- Internet protocols; [120]see below.
-
- On a regular serial or Telnet connection where the other
- computer doesn't support Kermit protocol at all, you have
- several options. For example, if your desktop communications
- software supports Zmodem, use "rz" and "sz" on the host rather
- than Kermit. But if Kermit is your desktop software, and you
- are using it to make calls or network connections to other
- computers that don't support Kermit protocol (or that don't

- has external X, Y, or Zmodem programs that are redirectable,
- Kermit can use them as external protocols. HELP SET PROTOCOL
- for details.

- with LOG SESSION (HELP LOG and HELP SET SESSION-LOG for

- KERMIT CLIENT/SERVER CONNECTIONS [ [124]Top ] [ [125]Contents ] [ [126]Next ]
- [ [127]Previous ]
-
- On any kind of connection you can make with Kermit -- serial, TCP/IP,
- X.25, etc -- you can set up a convenient client/server relationship
- between your Kermit client (the one that made the connection) and the
- Kermit program on the far end of the connection (the remote Kermit) by
- putting the remote Kermit in server mode. This is normally done by
- giving it a SERVER command, or by starting it with the -x command-line
- option. In some cases ([128]Internet Kermit Service, SSH connections
- to a Kermit subsystem, or specially configured hosts), there is
- already a Kermit server waiting on the far end. Here is a quick
- synopsis of the commands you can give to the client for interacting
- with the server:
-
- SEND [ switches ] filename
- Sends the named file to the server. The filename can include
- wildcards. Lots of switches are available for file selection,
- etc. Type HELP SEND at the client prompt for details.
-
- GET [ switches ] filename
- Asks the server to send the named file. The filename can
- include wildcards. Type HELP GET at the client prompt for
- details.
-
- BYE
- Terminates the server and closes your connection to it.
-
- FINISH
- Terminates the server. If you started the server yourself, this
- leaves the remote host at its shell prompt. If it was a
- dedicated server (such as IKSD or an SSH subsystem), FINISH is
- equivalent to BYE.
-
- SET LOCUS { LOCAL, REMOTE, AUTO }
- (C-Kermit 8.0.201 and later, K95 1.1.21 and later) This tells
- the client whether file-management commands like CD, PWD,
- DIRECTORY, DELETE, MKDIR, etc, should be executed locally or by
- the server. In this type of connection, the default is LOCAL.
- Use SET LOCUS REMOTE if you want Kermit to behave like an FTP
- client, in which case these commands are executed remotely, and
- their local versions must have an L prefix: LCD, LPWD,
- LDIRECTORY, etc. When LOCUS is LOCAL, then the remote versions
- must have an R prefix: RCD, RPWD, RDIRECTORY, etc. HELP SET
- LOCUS for details. SHOW COMMAND to see current locus.
-
- The following commands are affected by SET LOCUS:
-
- CD, LCD, RCD
- Change (working, current) directory. HELP CD for details.
-
- CDUP, LCDUP, RCDUP
- CD one level up.
-
- DIRECTORY, LDIRECTORY, RDIRECTORY
- Produce a directory listing. Many options are available for local
- listings. HELP DIRECTORY for details.
-
- DELETE, LDELETE, RDELETE
- Deletes files or directories. Many options available, HELP DELETE.
-
- RENAME, LRENAME, RRENAME
- Renames files or directories. Many options available, HELP RENAME.
-
- MKDIR, LMKDIR, RMKDIR
- Creates a directory. HELP MKDIR.
-
- RMDIR, LRMDIR, RRMDIR
- Removes a directory. HELP RMDIR. There are dozens -- maybe hundreds --
- of other commands, described in the built-in help, on the website,
- and/or in the published or online manuals. But even if you don't have
- access to documentation, you can "set locus remote" and then use
- pretty much the same commands you would use with any FTP client.

- KERMIT'S BUILT-IN FTP AND HTTP CLIENTS [ [132]Top ] [ [133]Contents ] [
- [134]Next ] [ [135]Previous ]
-
- Kermit's FTP client is like the regular Unix FTP client that you're
- used to, but with some differences:
-
- * It has lots more commands and features.
- * You can have an FTP session and a regular Kermit serial or Telnet
- session open at the same time.
- * FTP sessions can be fully automated.
-
- By default Kermit's FTP client tries its best to present the same user
- interface as a regular FTP client: PUT, GET, DIR, CD, BYE, etc, should
- work the same, even though some of these commands have different
- meaning in Kermit-to-Kermit connections; for example, CD, DIR, RENAME,
- etc, in Kermit act locally, whereas in FTP they are commands for the
- server. This might cause some confusion, but as in all things Kermit,
- you have total control:
-
- * The [136]SET LOCUS command lets you specify where file management
- commands should be executed -- locally or remotely -- for any kind
- of connection.
- * Any FTP command can be prefixed with the word "FTP" to remove any
- ambiguity.
-
- Pending publication of the next edition of the manual, the Kermit FTP
- client is thoroughly documented at the Kermit Project website:
-
- [137]http://www.columbia.edu/kermit/ftpclient.html
-
- You also can use HELP FTP and HELP SET FTP to get descriptions of
- Kermit's FTP-related commands.
-
- The HTTP client is similar to the FTP one, except you prefix each
- command with HTTP instead of FTP: HTTP OPEN, HTTP GET, HTTP PUT, HTTP
- CLOSE, etc. Type HELP HTTP for details, or visit the to view the
- [138]manual supplements. HTTP connections can be open at the same time
- as regular serial or Telnet connections and FTP connections. So Kermit
- can manage up to three types connections simultaneously.

- INTERNET KERMIT SERVICE [ [144]Top ] [ [145]Contents ] [ [146]Next ] [
- [147]Previous ]
-
- C-Kermit can be configured and run as an Internet service (called
- IKSD), similar to an FTP server (FTPD) except you can (but need not)
- interact with it directly, plus it does a lot more than an FTP server
- can do. The TCP port for IKSD is 1649. It uses Telnet protocol.
- C-Kermit can be an Internet Kermit Server, or it can be a client of an
- IKSD. You can make connections from C-Kermit to an IKSD with any of
- the following commands:
-
- telnet foo.bar.edu 1649
- telnet foo.bar.edu kermit ; if "kermit" is listed in /etc/services
- iksd foo.bar.edu
-
- The IKSD command is equivalent to a TELNET command specifying port
- 1649. For more information about making and using connections to an
- IKSD, see:
-
- [148]http://www.columbia.edu/kermit/cuiksd.html
-
- You can run an Internet Kermit Service on your own computer too (if
- you are the system administrator). For instructions, see:

- SECURITY [ [153]Top ] [ [154]Contents ] [ [155]Next ] [ [156]Previous ]
-
- All of C-Kermit's built-in TCP/IP networking methods (Telnet, Rlogin,
- IKSD, FTP, and HTTP) can be secured by one or more of the following
- IETF-approved methods:
-
- * MIT Kerberos IV
- * MIT Kerberos V
- * SSL/TLS
- * Stanford SRP
-
- For complete instructions see:
-

- And as noted previously, you can also make SSH connections with
- C-Kermit if you already have an SSH client installed.

-
- ALTERNATIVE COMMAND-LINE PERSONALITIES [ [161]Top ] [ [162]Contents ] [
- [163]Next ] [ [164]Previous ]
-
- When invoked as "kermit" or any other name besides any of the special
- ones, C-Kermit has the command-line options described above in the
- [165]OPTIONS section. However, if you invoke C-Kermit using any of the
- following names:
-
- telnet Telnet client
- ftp FTP client
- http HTTP client
- https Secure HTTP client
-
- Kermit's command-line personality changes to match. This can be done
- (among other ways) with symbolic links (symlinks). For example, if you
- want C-Kermit to be your regular Telnet client, or the Telnet helper
- of your Web browser, you can create a link like the following in a
- directory that lies in your PATH ahead of the regular telnet program:
-
- ln -s /usr/local/bin/kermit telnet
-
- Now when you give a "telnet" command, you are invoking Kermit instead,
- but with its Telnet command-line personality so, for example:
-
- telnet xyzcorp.com
-
- Makes a Telnet connection to xyzcorp.com, and Kermit exits
- automatically when the connection is closed (just like the regular
- Telnet client). Type "telnet -h" to get a list of Kermit's
- Telnet-personality command-line options, which are intended to be as
- compatible as possible with the regular Telnet client.
-
- Similarly for FTP:
-
- ln -s /usr/local/bin/kermit ftp
-
- And now type "ftp -h" to see its command-line options, and use command
- lines just like you would give your regular FTP client:
-
- ftp -n xyzcorp.com
-
- but with additional options allowing an entire session to be specified
- on the command line, as explained in the C-Kermit [166]FTP client
- documentation.
-
- And similarly for HTTP:
-
- ln -s /usr/local/bin/kermit http
- ./http -h
- ./http www.columbia.edu -g kermit/index.html
-
- Finally, if Kermit's first command-line option is a Telnet, FTP, IKSD,
- or HTTP URL, Kermit automatically makes the appropriate kind of
- connection and, if indicated by the URL, takes the desired action:
-
- kermit telnet:xyzcorp.com ; Opens a Telnet session
- kermit telnet://olga@xyzcorp.com ; Ditto for user olga
- kermit ftp://olga@xyzcorp.com/public/oofa.zip ; Downloads a file
- kermit kermit://kermit.columbia.edu/kermit/f/READ.ME ; Ditto for IKSD
- kermit iksd://kermit.columbia.edu/kermit/f/READ.ME ; (This works too)
- kermit http://www.columbia.edu/kermit/index.html ; Grabs a web page
- kermit https://wwws.xyzcorp.com/secret/plan.html ; Grabs a secure web pag
