   Chris wrote this script for personal use.
   If it messes something up, that is your fault for
   using it in the first place.  By using this script
   you agree to this.

Usage: push.sh -f <file with list of routers> <file with commands for every router>
       push.sh -d <directory where command files are located - named by router host name>
       push.sh -p [you then paste the list of routers and list of commands into the cli]
