Indent case clauses by 2 spaces as well. # * Shell variable references: Use double-quote around shell variable # references always (except when word splitting is explicitly desired), # even when you know the double-quote are not needed. This style tends to # avoid undesired word splitting caused by omitted double-quotes (the # number one mistake in shell scripts). # When the referenced variable can only have a finite number of possible # values and these values are all simple words (e.g. true and false), it's # OK to omit the double-quotes. # * Backquotes: # - Use backquotes like in `command`, not $(command). # - Don't use `command` inside double-quotes. Instead assign the result of # `command` to a variable, and use the value of the variable afterwards. # * Functions: # - All functions that don't emulate a program or shell built-in have a name # that starts with 'func_'. # - Document the implicit and explicit arguments of all functions, as well # as their output variables and side effects. # * Use test condition instead of [ condition ]. # * Minimize the use of eval; when you need it, make sure the string to be # evaluated has a very simple syntactic structure. progname=$0 package=gnulib nl=' ' IFS=" "" $nl" # You can set AUTOCONFPATH to empty if autoconf ≥ 2.64 is already in your PATH.

BSD got it right (except that # BSD echo interprets '-n' as an option, which is also not desirable). # Nowadays the problem occurs in 4 situations: # - in bash, when the shell option xpg_echo is set (bash >= 2.04) # or when it was built with --enable-usg-echo-default (bash >= 2.0) # or when it was built with DEFAULT_ECHO_TO_USG (bash < 2.0), # - in zsh, when sh-emulation is not set, # - in ksh (e.g. AIX /bin/sh and Solaris /usr/xpg4/bin/sh are ksh instances, # and HP-UX /bin/sh and IRIX /bin/sh behave similarly), # - in Solaris /bin/sh and OSF/1 /bin/sh. # We try the following workarounds: # - for all: respawn using $CONFIG_SHELL if that is set and works. # - for bash >= 2.04: unset the shell option xpg_echo. # - for bash >= 2.0: define echo to a function that uses the printf built-in. # - for bash < 2.0: define echo to a function that uses cat of a here document. # - for zsh: turn sh-emulation on. # - for ksh: alias echo to 'print -r'. # - for ksh: alias echo to a function that uses cat of a here document. # - for Solaris /bin/sh and OSF/1 /bin/sh: respawn using /bin/ksh and rely on # the ksh workaround. # - otherwise: respawn using /bin/sh and rely on the workarounds. # When respawning, we pass --no-reexec as first argument, so as to avoid # turning this script into a fork bomb in unlucky situations. # # Problem 2 is specific to bash 3.2 and affects the 'echo' built-in, but not # the 'printf' built-in.
