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:
Make a signature.
Encrypt for user id name.

This deals nicely with files having special characters in the file name (space ' or ").
Parallel is from https://savannah.nongnu.org/projects/parallel/
The preferred way for scripts (and easier to parse)
gets the last number of the mac address to use it for other stuff
I alias this as "tach":
alias tach='screen -x `screen -ls | grep Detached | cut -c -10`'
If you have several detached sessions it will just grab the first one. If you're running nested screens you can open new outer windows and run tach repeatedly to grab all the detached sessions into that one.
Gets the internal and external IP addresses of all your interfaces, or the ones given as arguments
--basic --user username:password
This will authenticate your Twitter username and password
Send data to the API with POST HTTP form.
Useful after a complete system update (without a new kernel) when you want to know, which processes need to be restarted
For disk space constraint testing. Leaves a little space available for creating temp files, etc. Easily free up the used disk space again by deleting the dummy00 file. Can tailor the testing by building smaller 'blocks' to suit the needs of the testing.
WARNING: do not do this to the '/' (root) filesystem unless you know what you are doing... on some systems it could crash the OS.
A few characters shorter that the other command
This was me just succumbing to the habits, but now I rarely use quit or vim directly, so beware! :)
