Menu Script

Shell Programming and Scripting
1

So, I need help writing a Menu script in UNIX.
First how can I use letters for the options instead of numbers?
Also, is there any templates out on the web I can use?

I bet there are even tons of examples in this forum here. There is a search option in the menu bar above.

#!/bin/sh
read input
case "${input}" in
     [aA])     echo "You pressed a";;
     [bB])     echo "You pressed b";;
     [cC])     echo "You pressed c";;
     [0-9]*)     echo "Somehow that felt like a number";;
     *)     echo "Try again";;
esac

exit 0
