Linux (+ open source tools) as a swiss army knife, 2002-11-18
Reviewer rating:
Technically, Linux is the name for the operating system kernel at the heart of "Linux" distributions such as RedHat and Debian. When most people "use" Linux, they are in fact using the shell, the web server, or any other of the zillions of open source programs that (1) are available for, (2) are distributed with, or (3) can run atop the Linux kernel.
It used to be that there were only a few things you could do with a Linux box (namely run a Unix box as a web server) but the open source community has come a long way in providing (1) applications and (2) hardware support, so that you can now do a lot of things w/ your Linux box that used to only be doable on a Windoze box.
Schwarz et al have put together a smorgasbord of things you can do with your Linux box. These projects range from things you would tend to do on a Unix box (eg IP Masquerade, SSH, system security, even a chapter on writing Apache modules!) to stuff you would expect to need to do on a Windoze box (eg burning CDRs, syncing with Palm devices, and audio/MIDI/image/video processing).
The level of detail in the chapters (as well as the required level of Linux familiarity on the part of the reader) varies considerably -- a hazard of multiple authors and the breadth of the topics covered -- but each chapter starts off with a "Difficult-o-Meter" which more or less accurately states the level of Linux proficiency required.
That said, there are some real gems to be found in this book. There are some pretty hefty howto-like treatments in this book of topics such as system security, "undernets" (collaborative web sites), and setting up a web/IMAP/mail server.
There's a chapter on "Tools You Should Know", which lists the tools a typical Unix hacker should know: regular expressions, vi, dd, sed, diff, etc. Like some other parts of the book, this chapter doesn't give you a lot of information on these individual tools, but it brings them to your attention, so you at least know what to look for.
This book by itself won't turn a newbie into a Linux ninja after one reading, but it is a good overview of many different things that can be done with open source tools on a Linux box. I would highly encourage the prospective reader to take a look at the Table of Contents of this book. If you see a topic you're interested in, then this is a worthwhile book to buy. (I suspect that most folks running Linux at home at a beginner to intermediate level will find several bits of interest in this book.)
