Utilities are the applications that enable you to work on the system (not to be confused with the shell).
These utilities include the Web browser for navigating the Internet, word processing utilities, e-mail
programs, and other commands that will be discussed throughout this book.
Try It Out Run Unix from a CD-ROM
The best way to learn Unix is to follow along with the book and try some of the exercises while you
are reading. If you don’t have a current install of a Unix operating system, and you do have an Intel/
AMD-based system (a PC that is Windows compatible), you can use KNOPPIX, a bootable Linux distri-
bution. KNOPPIX enables you to try Unix right from a CD, without installing or modifying any other
operating system on your computer. It provides a full-featured Linux environment and is a great way to
see what Linux and Unix is about.
1. Use the copy of Knoppix included on this book’s CD or download the KNOPPIX ISO image
from one of the mirrors listed at
http://knopper.net/knoppix-mirrors/index-en.html.
There are usually two versions of the software, one in German and one in English; choose
the image with the extension
-EN.iso.
2. If you downloaded a copy of Knoppix, use your favorite CD-burning software to burn a copy of
the ISO onto a CD-R.
3. Insert the CD-ROM included with this book or the CD-R you created into your CD-ROM drive
and boot (load) from it. By default, most systems let you boot from a CD-ROM simply by putting
the disk in the drive. (If the CD-ROM doesn’t start automatically, you may need to contact your
computer manufacturer’s manual for instructions.) You’ll see the opening KNOPPIX screen,
which should be similar to the one in Figure 1-1.
