22 # CODING STYLE for this file:
23 # * Indentation: Indent by 2 spaces. Indent case clauses by 2 spaces as well.
24 # * Shell variable references: Use double-quote around shell variable
25 # references always (except when word splitting is explicitly desired),
26 # even when you know the double-quote are not needed. This style tends to
27 # avoid undesired word splitting caused by omitted double-quotes (the
28 # number one mistake in shell scripts).
29 # When the referenced variable can only have a finite number of possible
30 # values and these values are all simple words (e.g. true and false), it's
31 # OK to omit the double-quotes.
33 # - Use backquotes like in `command`, not $(command).
34 # - Don't use `command` inside double-quotes. Instead assign the result of
35 # `command` to a variable, and use the value of the variable afterwards.
37 # - All functions that don't emulate a program or shell built-in have a name
38 # that starts with 'func_'.
39 # - Document the implicit and explicit arguments of all functions, as well
40 # as their output variables and side effects.
41 # * Use test condition instead of [ condition ].
42 # * Minimize the use of eval; when you need it, make sure the string to be
43 # evaluated has a very simple syntactic structure.

903 # to standard error in bash 3.2.
905 # Problem 1 is a weird heritage from SVR4. BSD got it right (except that
906 # BSD echo interprets '-n' as an option, which is also not desirable).
907 # Nowadays the problem occurs in 4 situations:
908 # - in bash, when the shell option xpg_echo is set (bash >= 2.04)
909 # or when it was built with --enable-usg-echo-default (bash >= 2.0)
910 # or when it was built with DEFAULT_ECHO_TO_USG (bash < 2.0),
911 # - in zsh, when sh-emulation is not set,
912 # - in ksh (e.g. AIX /bin/sh and Solaris /usr/xpg4/bin/sh are ksh instances,
913 # and HP-UX /bin/sh and IRIX /bin/sh behave similarly),
914 # - in Solaris /bin/sh and OSF/1 /bin/sh.
915 # We try the following workarounds:
916 # - for all: respawn using $CONFIG_SHELL if that is set and works.
917 # - for bash >= 2.04: unset the shell option xpg_echo.
918 # - for bash >= 2.0: define echo to a function that uses the printf built-in.
919 # - for bash < 2.0: define echo to a function that uses cat of a here document.
920 # - for zsh: turn sh-emulation on.
921 # - for ksh: alias echo to 'print -r'.
922 # - for ksh: alias echo to a function that uses cat of a here document.
923 # - for Solaris /bin/sh and OSF/1 /bin/sh: respawn using /bin/ksh and rely on
924 # the ksh workaround.
925 # - otherwise: respawn using /bin/sh and rely on the workarounds.
926 # When respawning, we pass --no-reexec as first argument, so as to avoid
927 # turning this script into a fork bomb in unlucky situations.
929 # Problem 2 is specific to bash 3.2 and affects the 'echo' built-in, but not
930 # the 'printf' built-in. See
931 # <https://lists.gnu.org/r/bug-bash/2008-12/msg00050.html>
