Create swapme.sh

swap me:
#!/bin/bash
## swapip.sh by Jesse
## Swap IPs and Hostnames script.
## Will also ask about mac address at the end
# script assumes new host is in DNS
# DO NOT RUN VIA SSH. Script restarts network.
# and that's as frustrating as you would think if
# you don't have console access. This script was
# written for the casual user to update their hostname.
# assumes new host is in DNS. can't get update just IP.
