877 # BSD echo interprets '-n' as an option, which is also not desirable).
878 # Nowadays the problem occurs in 4 situations:
879 # - in bash, when the shell option xpg_echo is set (bash >= 2.04)
880 # or when it was built with --enable-usg-echo-default (bash >= 2.0)
881 # or when it was built with DEFAULT_ECHO_TO_USG (bash < 2.0),
882 # - in zsh, when sh-emulation is not set,
883 # - in ksh (e.g. AIX /bin/sh and Solaris /usr/xpg4/bin/sh are ksh instances,
884 # and HP-UX /bin/sh and IRIX /bin/sh behave similarly),
885 # - in Solaris /bin/sh and OSF/1 /bin/sh.
886 # We try the following workarounds:
887 # - for all: respawn using $CONFIG_SHELL if that is set and works.
888 # - for bash >= 2.04: unset the shell option xpg_echo.
889 # - for bash >= 2.0: define echo to a function that uses the printf built-in.
890 # - for bash < 2.0: define echo to a function that uses cat of a here document.
891 # - for zsh: turn sh-emulation on.
892 # - for ksh: alias echo to 'print -r'.
893 # - for ksh: alias echo to a function that uses cat of a here document.
894 # - for Solaris /bin/sh and OSF/1 /bin/sh: respawn using /bin/ksh and rely on
895 # the ksh workaround.
896 # - otherwise: respawn using /bin/sh and rely on the workarounds.
897 # When respawning, we pass --no-reexec as first argument, so as to avoid
898 # turning this script into a fork bomb in unlucky situations.
