By and large, this is an introductory Linux book, with sections on installing the operating system, getting around at the command line, manipulating files, and doing essential administration of users, devices, and network connections. As such, you'll find this book rewarding even if you're not particularly interested in earning your LPIC 1 certificate. The authors present lists of options and details, and include listings of command-line input and output, to illustrate what you should see as you work with Linux (Red Hat is the demo distribution). Questions and answers appear at chapter ends and on the companion CD-ROM. --David Wall
