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/

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.

Will run the script as root and exit if the wrong or no password is given. Also will keep the parameters active if any where given.

Know a better way?

If you can do better, submit your command here.

What others think

What is the [-t 0] for? It does not seem to be doing anything.

Also I would add some "||exit" after the sudo command as it will otherwise just run the command if you press enter 3 times.

houghi: It checks to see if STDIN is a terminal. If it is, sudo will work. Otherwise, it's probably a GUI application and will need gksu.
