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/
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,…):

calculate how many different lines between two files
Open Port Check
Get the longest match of file extension (Ex. For 'foo.tar.gz', you get '.tar.gz' instead of '.gz')
`pwd` returns the current path
`grep -o` prints each slash on new line
perl generates the paths sequence: './.', './../.', ...
`readlink` canonicalizes paths (it makes the things more transparent)
`xargs -tn1` applies chmod for each of them. Each command applied is getting printed to STDERR.
On wired connections set 'eth0' instead of 'wlan0'
Runs a diff on two files ignore comments and blank lines (diff -I=RE does not work as expected). Adapted from a post found on stackexchange.
Lists everithing using -l "long listing format" wich includes the space used by the folder. Displays it in -h "human readable form" (i.e. 2.2G, 32K), and -R recurses subfolders.
grep -e using a regex, show lines containing the word "total" or a ":" at the end of the line (those with the name of the folder) only.
Substitute for #11720
Can probably be even shorter and easier.
Requirements: curl, grep, awk, internet connection with access to wikipedia
If you can make shorter version of this listgetter, you are welcome to paste it here :)
Will search for the given pattern and build a list of occurrences.
Then you can use :copen and :cclose to toggle the list.
When browsing the list, ENTER will take you to that line in the file.
Old Sys5 system and SUN computers don't have the -H option. Adding /dev/null forces grep to use the multi-file output and report the file name.
Add this line to your ~/.gitconfig for a git alias "git brd" (i.e., brd = (br)anch+(d)ate) which sorts branches by date. Allows you to pass in limited "git branch" options such as "-r" (remote) or "-a" (all). (Note: forum added "$" prefix to command; obviously in gitconfig there is no "$" prefix.)
Remove old kernels (*-generic and *-generic-pae) via apt-get on debian/ubuntu based systems. Tested on ubuntu 10.04 - 12.04.
