Question

I am writing a bash script that uses calling syntax

script [options] [dir]

To retrieve the set of options and parse them I use getopts. But how can I get the dir argument? In general, if I retrieve the last argument as ${@:${#@}}, it does not have to be the dir, it can be still an option or a value of it.

Code I use for getopts:

DIR="."
RECURSIVE=
FILTER=
while getopts “hnf:” OPTION
do
case $OPTION in
    h)
        usage
        exit 1
        ;;
    n)
        RECURSIVE="-maxdepth 1"
        ;;
    f)
        FILTER=$OPTARG
        ;;
    \?)
         exit 1
         ;;
    :)
         exit 1
         ;;
esac
done

Can you help?

Answer 1

OPTIND stores the position of the processed parameter. After the loop do a:

shift $((OPTIND-1))

Now the directories are in $@, first directory is in $1.
