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.
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.
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,…):

If you add the bookmarklet to your browser's bookmarks with like say, the keyword 'cfu', you can for example type 'cfu hello' in the location bar and the %s gets replaced with 'hello'.
The bookmarklet will convert the search text to base64 for use with the commandlinefu website and will take you there. Tested with Firefox.
Run program as root by SSH key forwarding instead of sudoers.
Put this alias line in .bashrc or wherever you like. Alias arguments might need extra escaping.
You might wonder about security. But you'd block out root login as much as possible of course. In sshd_config you put this:
Match Address 127.0.0.1
Use when aptbackup will not start or you just want to see what's going on.
Protects your secret identity with a passphrase.
OSX 10.6 automatically does key forwarding and can store the passphrase in the keychain.
For other OSes, use ssh -A or set ForwardAgent in ssh_config to enable forwarding. Then use ssh-agent/ssh-add.
