Introduction

Linux广泛用于搭建服务器，这主要得益于其shell的强大功能。在配置管理Linux系统及服务器时，输入的指令都被传递到shell中执行，而通过shell的使用，用户就可以启动、挂起、停止进程，编写脚本程序及执行定时任务等。
所谓shell，是一种用C语言编写、介于系统用户层与核心程序间的具备特殊功能的程序接口。更确切地说，shell是一个命令行解释器，它对一些遵循语法输入的命令加以解释并传送到系统的核心中执行，再将执行结果返回。
用户为何要使用shell而不是与操作系统核心直接交互呢？其实，系统核心是系统资源的管理者与分配者，在用户需要计算机资源并向系统核心提出请求后，就等待系统分配资源。然而，从系统的角度来看，必须防止用户的操作错误对系统造成的伤害，因此要避免与用户直接交互。而且用户命令需要转为二进制代码才能用来操作计算机的硬件。通过shell能够很好解决以上问题。另外，虽然Linux系统已经具有比较强大的图形界面，但在很多情况下还需要使用文本界面，这就离不开shell脚本编程。shell互动地解释和执行用户输入的命令，定义各种变量和参数，还提供了许多只有在高级语言中才有的控制结构。而且通过shell脚本编程能够更加合理地安排和执行一些耗资源和耗时间的任务。可见shell脚本编程的重要。
目前，市场上已有不少Linux书籍，但大多以介绍shell命令的简单应用为主，很少深入讲解脚本编程。为了帮助读者系统地学习shell脚本编程，作者编写了此书。由于作者水平有限，书中难免有错漏之处，若读者在阅读过程中遇到疑问或有任何建议和意见，欢迎指正。
