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.

Mouse around the title of this item, and note that your cookies are being logged to the console. If I were evil, I could instead send everyone's cookies to my site, and then post up-votes on all my submissions using their cookies, and try to delete every other submission, until clfu was completely pwned by me, redirecting people to malware and porn sites, and so on.

Update - now fixed.

Alternatives

There are 2 alternatives - vote for the best!

Know a better way?

If you can do better, submit your command here.

What others think

Ok, very good. Issue now fixed - was due to a recent attempt to parse commands for <CTRL+A> like insertions. Managed to introduce a security hole at the same time.

I would probably rather you emailed me instead of posting the recipe to the world though.

I found it educational, as a user of commandlinefu. But as I site owner i know how @root feels.

Hey, thanks!

I found it by accident, and since I had to post a submission in order to test it, I figured this would get your attention. For all I know, someone was already using it quietly. I'll email you next time if I spot something like this.
