Not too much luck with that code, I have never used xdigit before.....
Obviously you are not using Korn Shell 93 then.

The following will work for bash
Code:
#!/bin/bash

while true
do
   read -p "Enter MAC address: "  MAC
   case "$MAC" in
     [[:xdigit:]][[:xdigit:]]:[[:xdigit:]][[:xdigit:]]:[[:xdigit:]][[:xdigit:]]:[[:xdigit:]][[:xdigit:]]:[[:xdigit:]][[:xdigit:]]:[[:xdigit:]][[:xdigit:]])
       break;;
   esac
   echo "Invalid MAC address"
done

The script may or may not work for your version of ksh. There are several version of ksh in common use. ksh88 is the original Korn Shell. pdksh is the public domain version of ksh88. It does not seen to be actively maintained. Solaris uses a heavily modified version of ksh88.
