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.

sudo vim /root/bin/
##uh... autocomplete doesn't work...
sudo ls /root/bin
##ah! that's the name of the file!
