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.

there's those backticks again... i swear we'll never rid ourselves of them

Comment by atoponce 246 weeks and 1 day ago

ffmpeg is giving error: "Unknown encoder 'libmp3lame' "

Which package contains this codec?

Comment by alperyilmaz 246 weeks ago

@alperyilmaz which *nix flavour? The lib of the lame command is actually libmp3lame.so/a, so the package is probably lame.

To make ffmpeg use it, you have to compile it with --enable-mp3lame.

@atoponce I read all about evil backticks, and I'll try to avoid them now.^^

How to extend this to download file directly with the name of the file matching the name on youtube title?
