What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

UpGuard checks and validates configurations for every major OS, network device, and cloud provider.

Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Grab an interface's IP from ifconfig without screen clutter

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.


There are 5 alternatives - vote for the best!

Know a better way?

If you can do better, submit your command here.

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
Comment by markdrago 441 weeks and 5 days ago

ifconfig eth0 | grep -w inet | cut -d":" -f2 | cut -d" " -f1

No need for awk or sed
