reboot

[theguy0000]

I successfully installed.

I log in, and I am given this:

theguy0000@debian:~$

how do I reboot / shut down the computer?

[Unforgiven]

As root, type "reboot", or "shutdown -h now".

Or if you're impatient and brave, pull the cable >

[theguy0000]

how do I do that as the root?

[oz]

open a terminal window and do: su
enter your password when asked and press enter
then enter the command as given above

...or you can install sudo and set it up so that you don't have to be root to shutdown/reboot. instead, you'd do the same command as a user:

sudo shutdown -r now
