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,…):
Subscribe to the feed for:
A simple directive which disables all aliases and functions for the command immediately following it. Shortcut for the bash built-in 'command' - "command linefoo".
There are 2 alternatives - vote for the best!
e.g. if rm is aliased for 'rm -i', you can escape the alias by prepending a backslash:
rm [file] # WILL prompt for confirmation per the alias
\rm [file] # will NOT prompt for confirmation per the default behavior of the command
say, someone has aliased ls to 'ls --color=always' and you want to temporarily override the alias (it does not override functions)
if you have a alias like this:
alias cp='cp -i'
# cp file1 file1.bak
# cp -i file1 file1.bak
(it will not overwrite file1.bak if it exist)
# \cp file1 file1.bak
# /bin/cp file1 file1.bak
(skip alias settings, it will overwrite file1.bak if it exist)
Most distributions alias cp to 'cp -i', which means when you attempt to copy into a directory that already contains the file, cp will prompt to overwrite. A great default to have, but when you mean to overwrite thousands of files, you don't want to sit there hitting [y] then [enter] thousands of times.
Enter the backslash. It runs the command unaliased, so as in the example, cp will happily overwrite existing files much in the way mv works.
