Get primary IP of the local machine

ifconfig $(route -n |grep -m1 -e ^'0\.0\.\0\.0' |awk '{print $NF}') |grep 'inet addr' |awk '{print $2}' |sed 's/addr://1'
Plenty of commands out there for finding external IP, but sometimes getting the [internal] IP bound to the NIC handling Internet traffic is useful. Probably not production worthy, but a useful quick kludge. Assumes IPv4 and no fancy routing.
