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.
If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/

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,…):

Any changes to BASH shell made in .bashrc will be active in the current terminal window from the moment you execute this command, ie. aliases, prompt settings etc. No need to restart terminal.
(In BASH 'source' simile to 'eval' lets you generally execute any bunch of commands stacked in a text file).
Changes your group to the default group, has the same effect as sourcing your profile/rc file (in any shell) or logging out and back in again.
You may want to just use the shortcut "." instead of "source"
Simply sourcing .bashrc does not function correctly when you edit it and change an alias for a function or the other way round with the *same name*.
I therefor use this function. Prior to re-sourcing .bashrc it unsets all aliases and functions.
If you can do better, submit your command here.
