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.

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

Know a better way?

If you can do better, submit your command here.

What others think

If you have the Perl 'rename' installed, you can use the already known:

rename 's/foo/bar/' foo*.jpg

for file in foo*.jpg; do mv "$file" "${file/foo/bar}"; done

This is the *definition* of command-line-fu.

Comment by dfego 404 weeks ago

The util-linux-ng rename works nicely here too. At least in debian/ubuntu it is included by default and invoked explicitly as rename.ul:

rename.ul foo bar *.jpg

no quoting here, and the shell will expand *.jpg. If you needed to go recursive, in zsh and bash4.0 just replace *.jpg with **/*.jpg, otherwise find works for this:

find . -name "foo*.jpg" -exec rename.ul foo bar {} +


Pretty soon I am going to start keeping a running count of how file-renaming submissions have been made here at commandlinefu.
