Book Description
This book is about writing software that makes the most effective use of the system you're running on -- code that interfaces directly with the kernel and core system libraries, including the shell, text editor, compiler, debugger, core utilities, and system daemons. The majority of both Unix and Linux code is still written at the system level, and Linux System Programming focuses on everything above the kernel, where applications such as Apache, bash, cp, vim, Emacs, gcc, gdb, glibc, ls, mv, and X exist.
Written primarily for engineers looking to program (better) at the low level, this book is an ideal teaching tool for any programmer. Even with the trend toward high-level development, either through web software (such as PHP) or managed code (C#), someone still has to write the PHP interpreter and the C# virtual machine. Linux System Programming gives you an understanding of core internals that makes for better code, no matter where it appears in the stack. Debugging high-level code often requires you to understand the system calls and kernel behavior of your operating system, too.
Key topics include:
An overview of Linux, the kernel, the C library, and the C compiler
Reading from and writing to files, along with other basic file I/O operations, including how the Linux kernel implements and manages file I/O
Buffer size management, including the Standard I/O library
Advanced I/O interfaces, memory mappings, and optimization techniques
The family of system calls for basic process management
Advanced process management, including real-time processes
File and directories-creating, moving, copying, deleting, and managing them
Memory management -- interfaces for allocating memory, managing the memory you have, and optimizing your memory access
Signals and their role on a Unix system, plus basic and advanced signal interfaces
Time, sleeping, and clock management, starting with the basics and continuing through POSIX clocks and high resolution timers
With Linux System Programming, you will be able to take an in-depth look at Linux from both a theoretical and an applied perspective as you cover a wide range of programming topics.

读后感
没觉得有多特别，后来发现LKD也是作者的作品，所以静下心来读，这书还是很不错的。 买了一堆Unix编程的书，都没有好好读过。 这次要看完这本。加油。
评分以前受到amazon上评论的影响，一直以为这就是本API Reference，所以买来后一直都没翻过。前几天偶然翻看，才发觉误会了。这不是类似APUE那种手把手教你的书，这本书中往往是用短短的一段话来陈述了一些概念背后的东西，注意，是“陈述”，没有循循善诱。所以看此书之前最好还是...

用户评价
对一个一直在应用层开发的工程师来说，如果对系统层有好奇心，可以读读这本书，有些东西就很明显了。很棒。
评分基本上, 我是把它当系统调用参考书来看的. 当然它的内涵远不止于此.
评分真的是误会这本书了呢。。。（注意“呢”）
评分帮我扫清了一些知识盲点
评分浩如烟海的man手册不是那么容易抓住重点，这个时候你需要这本书，但非常可惜的是，本书没有网络和多线程的相关内容。
