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:
Calculate foldersize for each website on an ISPConfig environment. It doesn't add the jail size. Just the "public_html".
# Limited and very hacky wildcard rename
# works for rename *.ext *.other

# but fails for rename file*ext other*other and many more
# Might be good to merge this technique with mmv command...

defunct processes (zombies) usually have to be killed by killing their parent processes. this command retrieves such zombies and their immediate parents and kills all of the matching processes.
Exactly the same effect with 3 less characters ;-) (Removes all files/filesystems of a harddisk. It removes EVERYTHING of your hard disk. Be careful when to select a device.)
You can press Ctrl + C after few seconds
If you have a folder with thousand of files and want to have many folder with only 100 file per folder, run this.
It will create 0/,1/ etc and put 100 file inside each one.
But find will return true even if it don't find anything ...
This option selects the listing of all Internet and x.25 (HP-UX) network files.

I love CiteULike. It makes keeping a bibtex library easy and keeps all my papers in one place. However, it can be a pain when I add new entries and have to go through the procedure for downloading the new version in my browser, so I made this to grab it for me! I actually pipe it directly into a couple of SED one liners to tidy it up a bit too. Extremely useful, especially if you make a custom BibTeX script that does this first. That way you can sort a fresh BibTeX file for each new paper with no faf.
To use just replace with your CiteULike user name. It doesn't download entries that you've hidden but I don't use that feature anyway.

Simple Google Chrome profile manager using zenity for profile name input. Place this in a shell script and then use the path to it as the command field in a gnome/kde shortcut. When you start it you will be prompted for a profile to use, if you leave it blank you should get the default profile.
Can be useful to rip a CD.
This adds all new files to SVN recursively. It doesn't work for files that have spaces in their name, but why would you create a file with a space in its name in the first place?
