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:
RU: Найдет число файлов в папке по данной маске в цикле по дням месяца
A very simple command to toggle Chrome?s default style sheet. It uses the test command to see if the "Custom.css.off" file exists, if so, it will become "Custom.css", and if not, "Custom.css" is moved to "Custom.css.off" Thus, swapping.
This is accomplished with "&&" and "||"
The 'rename' command with the first argument as "'s/\.//'" and the second argument as "" will remove the specified extension from the filenames.
A simple bash function to the find command. I use this much more than find itself.

rename a network interface

Realtime lines per second in a log file using python ... identical to perl version, except python is much better :)
chmod authorized_keys so you don't get "Authentication refused: bad ownership or modes for file /home/user/.ssh/authorized_keys"
Receives bzip'd tar archive via netcat (openbsd nc) and stores locally. Displays size with pv. Start this receiver first, then the sender.
Warning this will allow you to write to the system image on the phone, not recommended. But sometimes useful.
Iozone with a file of 2GB, 64KB record size, write/rewrite and read/re-read test, using just one thread.
Where ^M is entered by ctrl-v-m (v then m). Especially useful on cygwin when checking into a version control system. If you're not using all cygwin tools (e.g. strawberry perl instead of cygwin perl) you'll find yourself dealing with this constantly.
-U tells grep to process the file as binary; it needs this to work
-I ignores binary files so you won't get false positives
-l only prints the filename instead of the offending lines
On a machine behind a firewall, it's possible to pass the proxy server address in as a prefix to wget to avoid having to set it as an environment variable first.
