Read just the IP address of a device

ifconfig $DEVICE | perl -lne '/inet addr:([\d.]+)/ and print $1'
Found this useful for scripts where I needed to work with the machine's IP. If $DEVICE is not specified, this will return all IPs on the machine. If $DEVICE is set to a network adapter, it will return just that adapter's IP.
