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.

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,…):

Can be used in a firewall script, e.g. to avoid logging broadcast packtes.
Get the hour and greet the user!
Make sure you add this to your bashrc, for a pleasant hacking experience!
enable each bash completion that you have installed at your system, that's very nice ;)
Maybe not the quicker because of the sort command, but it will also look in other man sections.

I just wanted a simple DNS request.

Gets the authors, sorts by number of commits (as a vague way of estimating how much of the project is their work, i.e. the higher in the list, the more they've done) and then outputs the results.
There is a common command for outputting a field or list of fields from each line in a file. Why wouldn't you just use cut?
Most systems (at least my macbook) have system users defined, such as _www and using "users" for example will not list them. This command allows you to see who the 'virtual' users are on your system.
I've been using it in a script to build from scratch proxy servers.
Simple and easy. No regex, no search and replace. Just clean, built-in tools.
This is helpful if you connect to several networks with different subnets such as 192 networks, 10 networks, etc. Cuts first three octets of ip from ifconfig command and runs nmap ping scan on that subnet.
Replace wlan0 with your interface. Assumes class c network, if class b use: cut -d "." -f 1-2 and change nmap command accordingly.
This is an easy way to quickly get a status for a device in multipath on SLES systems, as long as the server is configured based on Novell's standards, where multipathed disks are referred to by /dev/disk/by-... tree. Make sure to replace name_of_vg with your Volume Group name.
