Usage: parse_option $SHORT_OPTS $LONG_OPTS "$@" + +parseopts.sh: +A getopt_long-like parser which portably supports longopts and shortopts +with some GNU extensions. It does not allow for options with optional +arguments. For both short and long opts, options requiring an argument +should be suffixed with a colon. After the first argument containing +the short opts, any number of valid long opts may be be passed. The end +of the options delimiter must then be added, followed by the user arguments +to the calling program. + +Reccommended Usage: + OPT_SHORT='fb:z' + OPT_LONG=('foo' 'bar:' 'baz') + if ! parseopts "$OPT_SHORT" "${OPT_LONG[@]}" -- "$@"; then + exit 1 + fi + set -- "${OPTRET[@]}" +Returns: + 0: parse success + 1: parse failure (error message supplied) |
