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:
This oneliner gets all the 'modified' files in your git repository, and opens all of them in vim.
Very handy when you're starting to work in the morning and you simply want to review your modified files before committing them.
Maybe there are better ways to do that (and maybe integrated in vim and/or git, who knows), but I found quicker to do this oneliner.
There is 1 alternative - vote for the best!
The option --porcelain makes the output of git easier to parse.
This one-liner may not work if there is a space in the modified file name.
For editing files added to the index:
vim `git diff --name-only --cached`
To edit all changed files:
vim `git diff --name-only HEAD`
To edit changed files matching glob:
vim `git diff --name-only -- '*.html'`
If the commands needs to support filenames with whitespace, it gets a bit hacky (see http://superuser.com/questions/336016/invoking-vi-through-find-xargs-breaks-my-terminal-why for the reason):
git diff --name-only -z | xargs -0 bash -c '</dev/tty vim "$@"' x
The last part can be put in a script named e.g. vimargs, and used with any command outputting NUL separated filenames:
git grep -lz foobar | vimargs
Opens all files in the index (modified plus not added yet) in tabs in vim.
Works even with spaces in filenames.
As an alias in .gitconfig:
editchanged = "!git status --porcelain | sed -ne 's/^ M //p' | tr '\\n' '\\0' | tr -d '\"' | xargs -0 vim"
