YubNub (external link) is the command line of the internet. Or should I say one of the command lines, as there are a few. But Yubnub is the best I’ve seen.

It has a simple interface just like Google. A textbox in the middle of a page. A large logo. Some writing. However with the textbox you can do most things you’d ever do on the web, and if you can’t, you can make it so you can. So you can.

Typing “g” followed by a word searches Google. “y” does the same for Yahoo!, “wp” does it for WikiPedia, “ebay” for ebay, “cnn” for CNN, “flk” for flikr, “gim” for Google Images …

And if a service that you like or a webpage you often visit isn’t available in a command then you can use the best command of all “create” to create a new command. As long as the code you want to use isn’t taken, you can make it. And it’ll work instantly.

For instance if you type in “samsblog” then you’ve guess it, you end up here.

You don’t just have to use the tool on the website there are loads of ways to install YubNub including a search plugin and a Greasemonkey Script.
