Content preview from Fedora® Linux® TOOLBOX: 1000+ Commands for Fedora, CentOS, and Red Hat® Power Users

Acknowledgments

I would like to acknowledge the Fedora development community for their tenacity in turning out a high-quality Linux distribution about every six months. Likewise, I'd like to thank Red Hat, Inc., for their sponsorship of Fedora and excellent contributions to the free and open source software community.

Special thanks to François Caen for giving up most of his free time over the past year, while juggling his existing professional obligations, to co-author the book with me. Thomas Blader did his usual excellent job tech editing this book. At Wiley, I'd like to thank Jenny Watson for sticking with us through the development of the book. And, last but not least, thanks to Sara Shlaer for keeping us on track with schedules and supplying the never-ending to-do lists we needed to accomplish to get this book published.

—Christopher Negus

I would like to thank Chris Negus for giving me the opportunity to co-author this book with him. We had wanted to write together for the last couple of years, and this Toolbox series was the perfect fit for our collaboration.

I couldn't have worked on this book without the unrelenting support from my wife, Tonya. Thank you for emptying the dishwasher all these times even though we both know it's my job.

Thanks to Thomas Blader for his detailed tech editing. Having done some tech editing in the past, I know what a tough job it can be. Thanks to Sara Shlaer and Jenny Watson at Wiley for being the most patient cat-herders out there. Special thanks ...

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.
