Cut the power with terminal or a script?

[Agent-X]

I was using Ubuntu recently and some of the shutdown commands. To say the least, the way computers turn off today is not exactly what I'm looking for.

I want a way of simply turning off the computer. A "hard shutdown," if you will. I want a script that is similar to "pulling the plug."

I figure I could eventually use xbindkeys to use a key commands, but at the moment, I'd interested in whether or not Linux is capable of turning off the computer without going through a "kill process."

It is possible?
How could it be done?

Check out the 'poweroff' command, particularly the '-f' flag.

I tried that, but the system froze when I did that. It froze at the terminal and nothing else happened. All the hardware froze, too.

$ sudo su
$ poweroff -f

and then it freezes.

I'm using Ubuntu Feisty.
