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

What others think

First, http://www.commandlinefu.com/commands/view/1387/backticks-are-evil. Second, why is this even remotely useful?

Comment by atoponce 426 weeks and 1 day ago

atoponce, I think the real question is why should this be considered non-trivial enough to be included here?

Personally, I don't care as much about the usefulness, as the non-trivialness. I personally don't find many of the commands useful -- but others might, in different circumstances.

I don't see different circumstances turning the trivial into non-trivial, though.

@ozymandias I have no idea what you're trying to say.

Comment by atoponce 426 weeks and 1 day ago

find . -iname '*php' -exec wc -l {} \; as a better alternative

Comment by salparadise 426 weeks and 1 day ago

atoponce, it's usefulness does not matter to me. What is important is non-trivialness. This is not a place to document all possible command functions -- only the non-obvious. Using find to create a list of files to pass to wc is pretty darn trivial. Any shell user worth their salt should be able to come up with an identical solution to that problem instantly.

Comment by ozymandias 426 weeks ago

@salparadise I don't find this to be a better alternative, as it doesn't display a total line count.
