741 # echo '\n' | wc -l prints 1 when OK, 2 when KO

743 # Test cases for problem 2:
744 # echo hi | true frequently prints
745 # "bash: echo: write error: Broken pipe"
746 # to standard error in bash 3.2.
748 # Problem 1 is a weird heritage from SVR4. BSD got it right (except that
749 # BSD echo interprets '-n' as an option, which is also not desirable).
750 # Nowadays the problem occurs in 4 situations:
751 # - in bash, when the shell option xpg_echo is set (bash >= 2.04)
752 # or when it was built with --enable-usg-echo-default (bash >= 2.0)
753 # or when it was built with DEFAULT_ECHO_TO_USG (bash < 2.0),
754 # - in zsh, when sh-emulation is not set,
755 # - in ksh (e.g. AIX /bin/sh and Solaris /usr/xpg4/bin/sh are ksh instances,
756 # and HP-UX /bin/sh and IRIX /bin/sh behave similarly),
757 # - in Solaris /bin/sh and OSF/1 /bin/sh.
758 # We try the following workarounds:
759 # - for all: respawn using $CONFIG_SHELL if that is set and works.
760 # - for bash >= 2.04: unset the shell option xpg_echo.
761 # - for bash >= 2.0: define echo to a function that uses the printf built-in.
762 # - for bash < 2.0: define echo to a function that uses cat of a here document.
763 # - for zsh: turn sh-emulation on.
764 # - for ksh: alias echo to 'print -r'.
765 # - for ksh: alias echo to a function that uses cat of a here document.
766 # - for Solaris /bin/sh and OSF/1 /bin/sh: respawn using /bin/ksh and rely on
767 # the ksh workaround.
768 # - otherwise: respawn using /bin/sh and rely on the workarounds.
769 # When respawning, we pass --no-reexec as first argument, so as to avoid
770 # turning this script into a fork bomb in unlucky situations.
772 # Problem 2 is specific to bash 3.2 and affects the 'echo' built-in, but not
773 # the 'printf' built-in. See
