Linux Programming by Example

5 stars just because of the reason below. I read the whole book through, found two useful examples(topic) to resolve two of my issues. good book.

This is a good introductory book for Linux OS related programming concepts including memory management, files, IPC, signals and debugging. It does explain the concepts quite well and the code illustrations are very helpful. Its debugging and internalization chapters are noteworthy. As mentioned by others, this book does not cover threads and sockets. It could be better to provide more complete coverage of the topics such as IPC and memory management. For example, the IPC chapter is limited to pipes and fifos (they are not even explained depth enough). In short, I strongly recommend it as an introductory book for the topics covered.

An impressive work by a real expert.

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!

Don't judge a book by it's cover, especially this cover, with the cheesy lightsaber which screams, "secrets of the Unix Jedi". Read the the lines, "Linux" and "Fundamentals" on the cover, and that is what you need to know. If you are familiar with the classic "Advanced Unix Programming" you will be familiar with what this book covers and appreciative of the update. In short, this book covers the fundamentals of shell programming with C; files, directories, signals, memory allocation, process control, permissions, that sort of thing. It does not cover network programming or X11 GUI programming. What I liked about it was primarily that it imparted experience. For example the section on creating temporary files pointed out both good and bad ways to write the same functionality. The text was expository and informative. Where Advanced Unix Programming was a little dry and stiff in tone, this book is a little heftier, goes into more detail, and is written in a more experiential and friendly manner. There is a lot to like about this book. If the subject, within it's constraints, interests you, then you should get it. If only to broaden your depth of understanding as to how Unix works and how to write programs for it. If you are looking for books on network programming, xml, multi-threading, web serving, or X11, you should look elsewhere, but you should probably still look at this book to bone up on 'Linux' 'Fundamentals'.

Read the first two chapters so far. If you need pictures/screenshots, this book is not really for you. There is lots of text and sample code to go though.

Good book
