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.

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

OMG, what's that? What's wrong with



prog1 && prog2

Suppose prog1 is already running and you need prog2 to start after prog1 exits. However, there is a simpler way to do what the submitter has proposed:

while pkill -0 prog1; do sleep 10; done; prog2
Comment by daa 218 weeks and 2 days ago

@daa, yes you're right. But i 've just found another simpler :

press Ctrl+Z to suspend prog1 then :

fg && prog2
Comment by Saorel 218 weeks and 2 days ago

Nevertheless if you don't have hand on prog1, it's a good means to wait.

Comment by Saorel 218 weeks and 2 days ago

@daa you should submit this :)
