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/

Get involved!

You can sign-in using OpenID credentials, or register a traditional username and password.

First-time OpenID users will be automatically assigned a username which can be changed after signing in.

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.

It is not easy to make perl give a segfault, but this does it. This is a known issue but apparently not easy to fix. This is completely useless except for showing people that perl is not bullet-proof.

This helps to keep track of what is going on when you have several tabs open in your terminal. The title automatically changes when you change directories.

xwinwrap allows you to run any program in the root desktop pane. I like to run atlantis, it goes well against Fedora 10's blue sun background. At one time this also served a useful purpose for me as a workaround for a problem that would happen when the video card went into sleep mode.

OK, not the most useful but a good way to impress friends. Requires the "display" command from ImageMagick.

Substitute whatever track number you want into the "dvd://1" parameter. The "-aid 128" is to select the English language.
