Overview
This script will go through and update the serial on all your Bind/Named zone files. This is useful for administrators who may have ran sed, replace, or some other home grown application/script that may have modified the zone files. Once modified the serial needs to be incremented in order to let the DNS server and other DNS servers know that a change has been made and to dump any existing cache.
