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.

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.

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

kill process by name

Terminal - kill process by name
rush> processes.filter(:cmdline => /mc/).kill

User: chenge
kill process by name

It's easy to understand and remember. Need ruby and rush to do this.


There are 2 alternatives - vote for the best!

Terminal - Alternatives
pkill -x firefox
2010-05-02 02:17:21

Or even easier, if it's available:

killall firefox

I have no idea why you would want to rely on two unusual dependencies to do something that can be done a hundred ways from coreutils...

killall -9 <processname>
2011-12-09 02:53:46
User: symgryph
Functions: killall

Kills process by name

kill -9 `pgrep firefox`
2010-05-02 23:05:25
User: dustindorroh
Functions: kill
pgrep firefox

- this returns the Process ID for the signal firefox

kill -9 pid

- this kills the signal that had the given pid

cmd1 `cmd1` or cmd1 $(cmd1)

- here is the syntax for cmd2 to be executed first. Then the call to cmd2 is substituted with the output of cmd2, and cmd1 is executed.

Know a better way?

If you can do better, submit your command here.
