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.
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,…):

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:
Simply copies your public key to the remote system. For the first time, this will require a password for the [email protected] account. From then on, ssh will ask for your private key keyphrase occasionally but you won't need to use the password. Very handy when you're moving files for testing etc.
stty sane resets the tty to basic usable function. The ^J is a newline -- sometimes CR/LF interpretation is broken so use the ^J explicitly.
This is more or less the same as 'reset', but with two advantages: the initial LF character makes sure you're starting a new line to the tty driver, the final one is more reliably a line-end as CR is often unset; and second, 'stty sane' is reliable on older UNIX systems, especially Berkeley-based ones.
Simply translates whitespace to newlines. Could be enhanced to compress out extra newlines, but that might be better handled in the next tool down the pipe, with eg uniq(1).
