Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Get all IPs via ifconfig

Terminal - Get all IPs via ifconfig
ipconfig getpacket en0 | grep yi| sed s."yiaddr = "."en0: ". ipconfig getpacket en1 | grep yi| sed s."yiaddr = "."en1: ".

There are 5 alternatives - vote for the best!

Terminal - Alternatives
ifconfig | perl -nle'/dr:(\S+)/ && print $1'

Functions: ifconfig perl

Fetches the IPs and ONLY the IPs from ifconfig. Simplest, shortest, cleanest.

Perl is too good to be true...

(P.S.: credit should go to Peteris Krumins at catonmat.net)

ifconfig | awk -F':| +' '/ddr:/{print $4}'
2009-07-25 22:51:08
User: 0x89
Functions: awk ifconfig
Tags: Linux ifconfig

and, a lot uglier, with sed:

ifconfig | sed -n '/inet addr:/s/[^:]\+:\(\S\+\).*/\1/p'


Wanted to be shorter than the perl version. Still think that the perl version is the best..

ifconfig | awk '/ddr:[0-9]/ {sub(/addr:/, ""); print $2}'

User: danny_b85
Functions: awk ifconfig
Tags: Linux ifconfig

The initial version of this command also outputted extra empty lines, so it went like this:

This happened on Ubuntu, i haven't tested on anything else.

ifconfig | awk '/inet / {sub(/addr:/, "", $2); print $2}'
ifconfig | grep "inet addr" | cut -d: -f2 | cut -d' ' -f1

Know a better way?

If you can do better, submit your command here.

What others think

ipconfig en0? What operating system are you running?
