makeLocationAndStaticIP.sh

#!/bin/bash
# purpose: add a network location with manual IP info without switching 
#   This script lets you fill in settings and apply them on en0(assuming that's active)
#   but only interrupts current connectivity long enough to apply the settings,
#   it then immediately switches back. (It also assumes a 'Static' location doesn't already exist...)
#   Use at your own risk! No warranty granted or implied! Tell us we're doing it rong on twitter!
