How 'bout this one-liner:
IFADDR=`/sbin/ifconfig eth1 | grep "inet addr:" | cut -f2 -d: | cut -f1
-d" "`
IFADDR gets the output of the command pipeline inside the `s. Get the
output of /sbin/ifconfig for the specific interface, grab just the
address line, grab from the colon to the next colon, then trim off the
end of the IP address.
Anyone got anything shorter??
