说明：  很好的linux编程书籍，对linux的各个方面都有章节详细介绍，尤其是对debug和GDB的使用为其他书籍所不多见。
(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.)
