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:
echo '127.0.0.1 facebook.com' | sudo tee -a /etc/hosts
Do not execute this command if you don't know what you are doing.
This command will open tcp port 3000 in your machine
run `sudo update-rc.d gdm defaults` to get it back

i'm using gawk, you may get varying mileage with other varieties. You might want to change the / after du to say, /home/ or /var or something, otherwise this command might take quite some time to complete. Sorry it's so obsfucated, I had to turn a script into a one-liner under 255 characters for commandlinefu. Note: the bar ratio is relative, so the highest ratio of the total disk, "anchors" the rest of the graph. EDIT: the math was slightly wrong, fixed it. Also, made it compliant with older versions of df.
This will limit the average amount of CPU it consumes.
This script will run each time you boot up.The script must be in /etc/init.d directory.
This short snippet outputs the state of all containers available on your system. It is quite helpful to see which ones are running and which are stopped. Please notice that the "sort -u" is needed, otherwise running containers will be reported twice (see output of "lxc-ls" on its own for why)

From live CD mount(open) the Ubuntu installed drive.
Copy the location (press Ctrl+l, Ctrl+c ) eg: /media/ubuntuuuu

It locate the urls of audio and video files so that they can be recorded.
Find which directories on your system contain a lot of files.

Will run the script as root and exit if the wrong or no password is given. Also will keep the parameters active if any where given.
Place this code at the beginning of your script to ensure that it can only be executed by the root.
