How to make a multi-character parameter in UNIX using getopt? -

-

i'm trying make getopt command such when pass "-ab" parameter script, script treat -ab single parameter.

#!/bin/sh args=`getopt "ab":fc:d $*` set -- $args in $args case "$i" in         -ab) shift;echo "you typed ab $1.";shift;;         -c) shift;echo "you typed c $1";shift;; esac done

however, not seem work. can offer assistance?

getopt doesn't support looking for. can either use single-letter (-a) or long options (--long). -ab treated same way -a b: option a argument b. note long options prefixed 2 dashes.
