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.


If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/

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.

Colorize matching string without skipping others

this is useful to highlight only some code without losing other lines (eg. software, logs, scripts)

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives
tail -F file | egrep --color 'pattern|$'
sed 's/pattern/^[[1m&^[[0m/g'

Know a better way?

If you can do better, submit your command here.

What others think

You should explain yourself a bit better.

This is a very subtle but very useful idea.

By adding an empty search string to egrep (the "|" on the end), you've invented a "cat" that highlights things.

Very nice.
