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/

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.

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.

Seems only works for emacs mode of bash

Comment by nonoob 192 weeks and 3 days ago

yes-yes, this only works if you use the emacs mode in bash.

Comment by davidpgero 192 weeks and 3 days ago

doesn't work for most commands, hence useless most of the time.

Comment by gerard 192 weeks and 3 days ago

Should read "execute and re-edit."

Great for when you're working on commandline-fu that takes a couple test runs before getting it right.

Comment by h3xx 192 weeks and 3 days ago

Just as pressing "Enter" key.

Comment by totti 192 weeks and 3 days ago

Nice to know this "execute and re-edit", but definitely a misleading explanation here. If you don't know what it really does, it could even be dangerous. I *might* upvote this with a different explanation, but as it is I'm going to downvote, sorry :)

Comment by wipu 192 weeks and 3 days ago

Ah, a Bash-ism using emacs mode. Gotta love non-portable commands.

Comment by atoponce 192 weeks and 2 days ago

does not work in /bin/sh , /bin/bash nor /bin/tcsh

Comment by Mozai 192 weeks and 2 days ago
