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.

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}'

and, a lot uglier, with sed:

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

Edit:

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}'

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

192.168.166.48

127.0.0.1

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?
