208 Welcome to Linux

[billy@localhost billy]$ su

Password: yourrootpassword

[root@localhost billy]#

This will allow you to change from your regular user account to the root account.

Please Note: when you’re in the root account, you are commander in chief of everything on your

system, so be careful.

Tip: The command su means substitute users, which lets you log into temporarily log

in as another user.

Brieﬂy, we’ll ﬁnd the Linux kernel version; then, we’ll use the mkbootdisk command to make a

bootable ﬂoppy from the kernel.

Put a standard diskette in the ﬂoppy drive.

Tip: In Linux, the ﬂoppy drive is referred to as /dev/fd0.

If you’ve previously used the diskette, remember: You will lose anything that had been on that

diskette!

Now, at the prompt, type:

cd /lib/modules

(Shown in ﬁgure 15.17.)

Now, type:

The command ls will list the contents of a directory. (You can learn more about the cd and ls

commands in Chapter 16 on page 217). For now, just type the commands as you see them.)

Here, you can ﬁnd the kernel version of your Red Hat Linux system. The kernel is the heart of any

Linux system. Your kernel version will be something similar to:

2.2.x-yy

1 2 ... 215 216 217 218 219 220 221 222 223 224 225 ... 299 300
