Grab an interface's IP from ifconfig without screen clutter

ifconfig eth1 | grep inet\ addr | awk '{print $2}' | cut -d: -f2 | sed s/^/eth1:\ /g
Sometimes, you don't really care about all the other information that ifconfig spits at you (however useful it may otherwise be). You just want an IP. This strips out all the crap and gives you exactly what you want.
Sample Output
eth1: 192.168.100.73

What Others Think

You can do all that with just awk: ifconfig eth1 | awk '/inet addr:/{sub(/^.*inet addr:/,"eth1: ");print $1,$2}' You can also do it with just sed: ifconfig eth1 | sed -n -e 's/Bcast:.*$//' -e 's/^.*inet addr:/eth1: /;2p'

I prefer using /sbin/ip over /sbin/ifconfig ip addr show dev eth0 | grep 'inet ' | awk '{print $2}' | cut -d'/' -f 1

ifconfig eth0 | grep -w inet | cut -d":" -f2 | cut -d" " -f1 No need for awk or sed
