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:
Opens a snapshot of a live UFS2 filesystem, runs dump to generate a full filesystem backup which is run through gzip. The filesystem must support snapshots and have a .snap directory in the filesystem root.
To restore the backup, one can do
zcat /path/to/adXsYz.dump.gz | restore -rf -
Dumps a compressed svn backup to a file, and emails the files along with any messages as the body of the email
This command will nicely dump a filesystem to STDOUT, compress it, encrypt it with the gpg key of your choice, throttle the the data stream to 60kb/s and finally use ssh to copy the contents to an image on a remote machine.
Use of hotcopy for safety/stability of the backups.
This command dumps all SVN repositories inside of folder "repMainPath" (not recursively) to the folder "dumpPath", where one dump file will be created for each SVN repository.
This will compress the root directory to an external hard drive and split it to parts once it reaches the 4 Gigs file system limit.
You can simply restore it with:
restore ivf /media/My\ Passport/Fedora10bckup/root_dump_fedora
On Windows 2000 or newer, you can use the command line to save the current network interface info.
You can then edit the text file and re-apply it using the netsh -f command (or netsh exec). Keep a bunch of text files around to quickly switch connection info without using extra software.
...can do similar w/ tar, dd, xfsdump, e2fsdump, etc.
