15.7 Shutting Down 205

log out from your account, which will return you to your login screen, but if you want to completely

shut off your machine, you’ve got a couple more steps to take.

Figure 15.15: The command ‘top’ shows you running processes

Here’s why: Even though you may not be typing, listening to music or browsing with Netscape, your

machine is still working on a variety of processes in the background. (A process is a program which

is being executed. Multiple processes are running all the time on your system.)

Tip: Curious to take a peek? Just go to a shell prompt and type top.You’ll see the

processes that are currently running (see ﬁgure 15.15). To quit this view, type

Q .

(To learn more about the top command, type man top at the shell prompt; to move

forward a screen, press the

Spacebar ;tomovebackascreen,press B ;toquit,press Q .

You’ll learn more about these “man pages” later in this chapter.)

Like a faithful assistant, your Linux system is carrying out tasks silently all the time. You can’tjust

turn out the lights and lock the door on your assistant. Instead, you’ve got to give them time to put

away their work and make sure everything’s in its proper place before saying “good night.”

To shutdown or reboot while you’re in GNOME, exit from your X session (panel

Log out). Once

you’re at the login screen, left-click on Options,andselectHalt or Reboot.

You’ll then be asked whether you want to stop or restart your machine. Choose Halt to shutdown

your machine; chooseRestart to restart, or “reboot” your machine.

At the shell prompt, you can reboot or halt your system from your root account.
