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.

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

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.

What others think

loving the output of this command:

tux2231> sudo -l We trust you have received the usual lecture from the local System Administrator. It usually boils down to these two things: #1) Respect the privacy of others. #2) Think before you type. Password: Sorry, user hygrep may not run sudo on tux2231. tux2231>

@hygren: that only works if you actually have any rights assigned to your user in /etc/sudoers. Note that "sudo -l" did tell you that you had absolutely no rights ;)
