15.8 Pulling Yourself Up by the Boot 207

Tip: Try substituting +5 for now;you’ll ﬁnd that you’ve just commanded your assistant

to put everything away and stop working in ﬁve minutes.

You can learn more about the shutdown command by typing:

man shutdown

at a shell prompt. You’ll be presented with a “man page,” which will tell you about this command.

To go forward a screen, press the

Spacebar ;togobackascreen,press B ;andtoquit,press Q .

Summary: To shutdown or reboot from GNOME, from the log in screen, go to Options

Halt or Reboot. From the shell prompt: Log in as root, and type shutdown -r now

(to reboot) or shutdown -h now (to halt).

15.8 Pulling Yourself Up by the Boot

When you’re logged in as the root account, you might want to take a few minutes to create a fresh

“boot diskette” or copy the diskette you already have.

There are a number of reasons you should make a boot diskette: it can help you recover from a

system failure, it can help you test a new kernel you’ve downloaded and compiled and it can help

you share your computer with more than one operating system.

Tip: You can always use a copy of the boot diskette to form the ﬁrsthalfofarescuedisk

set. You’ll need a boot diskette and a rescue diskette to enter rescue mode. To read more

about rescue mode, see later in this chapter.

You were given the opportunity to make a boot disk when you installed Red Hat Linux. If you chose

not to make a boot disk at installation, here’s your chance to start from scratch.

For now, we’ll make boot disks from the shell prompt while we’re in an X session.

Go to the shell prompt: In GNOME, for example, left-click on the GNOME footprint on the panel,

go to Utilities in the menu and click on one of the items marked xterm or on the GNOME terminal

item.

Now, make sure you’re logged in as root. At the shell prompt, if you see something like [billy@localhost

billy], for example, type:

1 2 ... 214 215 216 217 218 219 220 221 222 223 224 ... 299 300
