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/

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.

Write a file you edited in Vim but that you do not have the permissions to write to (unless you use sudo.) Same as #1204 but without the echo to stdout that I find annoying.
There are 4 alternatives - vote for the best!
Calls sudo tee like all the other lines, but also automatically reloads the file.
Optionally you can add
command Wq :execute ':W' | :q
and
command WQ :Wq
to make quitting easier
probably just like 1204, but uses tee as a filter (+ I actually understand how this one works)
this avoids several VIM warnings, which I seem too stupid to disable: warning, readonly! and: file and buffer have changed, reload?!
Like the http://www.commandlinefu.com/commands/view/6327/open-file-with-sudo-when-there-is-no-write-permission, but works (in zsh; my commandlinefu is not strong enough to understand why bash don't like it) with vim options, like -O, and many input files.
There could be other mistakes.
If you can do better, submit your command here.

or better
:w !sudo cat > %
You can't do a :
:w !sudo cat > %becase the sudo don't work over a redirection ( >).
You can do something like that :
:w !sudo sh -c 'cat > %'
