749 # Test cases for problem 2:
750 # echo hi | true frequently prints
751 # "bash: echo: write error: Broken pipe"
752 # to standard error in bash 3.2.
753 #
754 # Problem 1 is a weird heritage from SVR4. BSD got it right (except that
755 # BSD echo interprets '-n' as an option, which is also not desirable).
756 # Nowadays the problem occurs in 4 situations:
757 # - in bash, when the shell option xpg_echo is set (bash >= 2.04)
758 # or when it was built with --enable-usg-echo-default (bash >= 2.0)
759 # or when it was built with DEFAULT_ECHO_TO_USG (bash < 2.0),
760 # - in zsh, when sh-emulation is not set,
761 # - in ksh (e.g. AIX /bin/sh and Solaris /usr/xpg4/bin/sh are ksh instances,
762 # and HP-UX /bin/sh and IRIX /bin/sh behave similarly),
763 # - in Solaris /bin/sh and OSF/1 /bin/sh.
764 # We try the following workarounds:
765 # - for all: respawn using $CONFIG_SHELL if that is set and works.
766 # - for bash >= 2.04: unset the shell option xpg_echo.
767 # - for bash >= 2.0: define echo to a function that uses the printf built-in.
768 # - for bash < 2.0: define echo to a function that uses cat of a here document.
769 # - for zsh: turn sh-emulation on.
770 # - for ksh: alias echo to 'print -r'.
771 # - for ksh: alias echo to a function that uses cat of a here document.
772 # - for Solaris /bin/sh and OSF/1 /bin/sh: respawn using /bin/ksh and rely on
773 # the ksh workaround.
774 # - otherwise: respawn using /bin/sh and rely on the workarounds.
775 # When respawning, we pass --no-reexec as first argument, so as to avoid
776 # turning this script into a fork bomb in unlucky situations.
777 #
