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/

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

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

Comment by atoponce 327 weeks and 3 days 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 327 weeks and 2 days ago

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

Comment by salparadise 327 weeks and 2 days 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 327 weeks and 2 days ago

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