Great real world examples

Linux Programming by Example: The Fundamentals is a great book that covers three main concepts in Linux programming: files, processes and debugging. In each part the author explains and gives several examples of functions, systems calls and APIs that will help the Linux programmer. He also includes several real world examples of how these concepts are implemented. Here are the some things that I found interesting:
The Good: 1) This book really focuses on the use of standards and good program design. Right from the beginning, the author goes out of his way to make the reader aware of standards from ISO and POSIX and how they apply to good programming and design. Along this line I also like that the author explains the benefits of - and promotes - the use of Gnu software. Being an avid Gnu user myself (as most Linux users are) I agree that Gnu software is generally better software.
2) I feel that knowledge is power, and the author goes along with this idea by showing how some things should *not* be done. He often points out several functions that are available but should be avoided. I appreciated this, and feel that it makes the reader an all-around better programmer. The author also frequently gives extra information and history which helps explain why things are the way they are. This was especially useful when explaining mount points and types of file system.
3) I liked the fact that the author uses real world examples to demonstrate the ideas being presented. I really appreciated the fact that he uses V7 code (older, smaller and less comlex code) to demonstrate his examples. This allowed me to be able to see how the features were implemented in simple code, without being overwhelmed by the modern equivalents. A great example is the V7 echo program - only 23 lines!
The Bad: There weren't too many things that I didn't like about this book, but if my arm was twisted I would say the following: 1) This book is called *Linux* Programming but really it is about Unix programming. I know they are similar, and maybe I am splitting hairs here, but the title could really be *Unix* Programming. Most of this stuff is generic Unix programming, and the author points out the special exceptions not only for Linux but for other Unix variants as well - such as BSD.
2) Don't confuse the word "Fundamental" with "Beginning." This book really isn't for beginning Linux programmers, but rather it teaches basic (or fundamental) concepts that Linux programmers should know and use. The reader needs to be moderately familiar with the C programming language if he or she is to be edified.
A great read, with some excellent examples of well written Linux programs. If you are interested in moving beyond basic Linux programming then you should definitely pick up a copy of this book!
An invaluable resource

This is an exceptionally fine book.
Robbins has supplied the reader with a vast number of
programs and a lot of elucidation. This is a primer in
Linux programming, but also serves as a tract on UNIX
programming. The illustrations stem, for the most part,
from actual GNU and Linux code.
This is an invaluable resource for those converting from
another system to Linux.
A new classic

I loved this book. It's earned an honored place on my bookshelf, and I'm going to recommend it to people who need information about Linux and UNIX development.Many computer books are practically obsolete before they ship: within a few months, "Learn Foomatic 4.3 in 21 Days" is in the bargain bin at the Dollar Tree. Some books have longer lives, and a few can remain useful for years. "Linux Programming by Example" (LPE) is in this last category; this book can stand alongside Steven's "Advanced UNIX Programming" as an essential tutorial and reference. LPE covers everything you'd expect (working with files, processes, signals, users) and some things you might not (internationalization). But it's this book's voice and unique perspective that make it truly a gem. LPE is written in a clear, friendly, authoritative style. As I read, I often felt that I had gained a new understanding of things I've known for years. The long and twisted history of UNIX has given rise to multiple competing APIs. Perhaps the greatest thing about this book is the way that Robbins cuts through these thickets, explaining your choices, pointing out the best alternatives, and explaining why they're the best. LPE's modern vantage point means it can cover V7, BSD, POSIX, and GNU APIs. The chapter on signals alone is worth the purchase price of the book for the way in which it clearly compares and contrasts the various signal APIs.
