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/

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.

Know a better way?

If you can do better, submit your command here.

What others think

The cat is unnecessary. You can just use something like this:

find . -name '*.java' | xargs wc -l

This approach is not the best one: it also counts blank lines and comments. Better use a dedicated tool to count lines, e.g. CLOC, loc, or similar.
