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

  • 772

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?

    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 $(expr $OPTIND - 1 )

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

  2. At the end of the parsing, once you have shifted the variable $@ contains the end of the line :

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