Hi. Is there a way I can get 2 or more arguments from an option?

Something like:

Usage: myscript -a arg1 arg2

Then a simple printing of arg1 and arg2 will do. I just need it as a template. The script should also work if no arguments for option "a" is specified. so running "myscript -a" will still do something.

I've tried using the getopts command but I can only seem to handle arg1.

Thanks in advance.

while [ x"$1" != x -a x"${1#-}" != x"$1" ]; do 
   case "$1" in 
   -a)  opta="$2 $3"; shift 3; ;;
   -*)  echo "Unknown option: $1"; shift ;;
   esac
done
echo $opta
