This is just a good way to evaluate arguments passed to a script that I've been using.

Code

#!/bin/bash
while [ $# != 0 ]
do
    case $1 in
        -a)
            var1=$2
             shift 2
            ;;
        -b)
            var2=$2
            shift 2
            ;;
        -c)
            var3=$2
            shift 2
            ;;
          *)
            echo "invalid argument $1"
            exit 1
    esac
done
