How can I get remaining args after pulling out parsed items using getopts?

Question

I want to parse some arguments to a bash script using getopts but want to be able to access the remaining args that are not included in the option list. So for example, if I have a call:

% script -a -b param -c param -d other arguments here

I would have:

while getopts "ab:c:d" opt ; do
.
done

What is the easiest way to get "other arguments here", which should be unprocessed by getopts?

Answer 1

you need to shift when you parse an arg, or put

shift $((OPTIND -1)) after you have finished parsing, then deal in the usual way e.g.

while getopts "ab:c:d" opt ; do
.
done
shift $(( $OPTIND -1 ))

while test $# -gt 0; do
echo $1
shift
done

the $(( )) is not available in all shells, for portability, you may want to use expr instead.
