Foreword

    OK, so you've mastered the basics of Linux. You can run ls, grep, find, and sort, and as a C or C++ programmer, you know how to use the Linux system calls. You knowthat there's much more to life than "point and click" and that Linux will give it to you. You're just not sure yet how. So you ask yourself, "What's next?"

    This book gives you the answer. John's knowledge is broad, and he shows the no-longer-novice Linux user how to climb up the next part of the learning curve towardmastery.

    From command-line tools for debugging and performance analysis to the range of files in /proc, John shows you how to use all of them to make your day-to-day life with Linux easier and more productive.

    Besides a lot of "what" (what tools, what options, what files), there's a lot of "why" here. John shows you why things work the way they do. In turn, this lets you under-stand why the "what" is effective and internalize the Zen of Linux (and Unix!). There's a ton of great stuff in this book. I hope you learn a lot. I know I did, and that's saying something.

Enjoy,
