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.
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.

Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):

Lists ONLY the files changed by the given HASH/HEAD/list of hashes, etc. The message, commit ID, author, etc. is not included
Best to try first with -n flag, to preview
Uses the last argument of the last executed command, and gets the directory name from it.
Use $!:t for the filename alone, without the dirname.
If you want certain files out of a directory hierarchy, this will copy just the listed files, but will create the directory hierarchy in the new location ($DIR/)
Simply shows virtualhosts enabled, root access not needed (assuming apache2ctl is non-root executable).
