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/

First-time OpenID users will be automatically assigned a username which can be changed after signing in.
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.

Add -depth to prevent find complaining (it will ensure empty trees are deleted, too) and --ignore-fail-on-non-empty to stop rmdir (gnu version) complaining:
find . -depth -type d -exec rmdir --ignore-fail-on-non-empty {} \;Of course for efficiency, you can use xargs:
find . -depth -type d -print0 | xargs -0 rmdir --ignore-fail-on-non-emptyfind -depth -type d -empty -exec rmdir {} \;or even better, (the + at the end acts like xargs)
find -depth -type d -empty -exec rmdir -v {} +
