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:
You need to apt-get install python-sqlparse. This command simply formats a sql query and prints it out. It is very useful when you want to move a sql query from commandline to a shell script. Everything is done locally, so you don't need to worry about copying sql query to external websites.
The equivalent of opening each file in vim and doing
gg=G:wq . Bufdo makes it faster by obviating the need to start vim for each file separately.
For slow flash memory (cheap thumb drive), ext4 is the fastest stable file system for all use cases with no relevant exception:
Since we can usually dispense with the benefits of a journal for this type of storage, this is a way to achieve the least awful I/O-speed.
Disabling the journal for an existing ext4 partition can be achieved using
tune2fs -O ^has_journal /dev/sdXN
Note that it is often recommended to format removable flash media with ext2, due to the lack of a journal. ext4 has many advantages over ext2 even without the journal, with much better speed as one of the consequences. So the only usecase for ext2 would be compatibility with very old software.
This will indent the input to be more readable. Warnings and messages are not send to STDOUT so you can just use a pipe to create the formatted outputfile, like:
tidy -i -xml in.xml > out.xml
xmllint2 comes with GNU libxml2 library.
The sample command searches for PHP files replacing tabs with spaces.
-u NONE # don't use vimrc
one may pass
