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/

Universal configuration monitoring and system of record for IT.

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.

What others think

The -e option isn't needed in this example (at least not on the two different linux systems I ran it on [CentOS 5, and a very old SUSE 7]).

meh. i meant to hit up, but my mouse moved as i clicked, and i accidentally voted it down. sorry.

i love this command. this beats hands down opening the file with vim, locating the line, and deleting it. quick, easy, painless. great command.
