Here’s a great resource for command-line geeks; you can browse and vote on snippets that people have posted and upload your own:
Command-Line-Fu 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 and discussed – digg-esque voting is also encouraged so the best float to the top.
