$PRODUCES shopt.c
$BUILTIN shopt
$FUNCTION shopt_builtin
$SHORT_DOC shopt [-pqsu] [-o long-option] optname [optname...]
Toggle the values of variables controlling optional behavior.
The -s flag means to enable (set) each OPTNAME; the -u flag
unsets each OPTNAME. The -q flag suppresses output; the exit
status indicates whether each OPTNAME is set or unset. The -o
option restricts the OPTNAMEs to those defined for use with
`set -o'. With no options, or with the -p option, a list of all
settable options is displayed, with an indication of whether or
not each is set.
$SHORT_DOC shopt [-pqsu] [-o] [optname ...]
Set and unset shell options.
Change the setting of each shell option OPTNAME. Without any option
arguments, list all shell options with an indication of whether or not each
is set.
Options:
-o restrict OPTNAMEs to those defined for use with `set -o'
-p print each shell option with an indication of its status
-q suppress output
-s enable (set) each OPTNAME
-u disable (unset) each OPTNAME
Exit Status:
Returns success if OPTNAME is enabled; fails if an invalid option is
given or OPTNAME is disabled.
