本书在一开始就给出一个概述和指南，论述了从grep到sed再到awk不断改进的功能。sed和awk具有相同的命令行语法，以脚本的形式接收用户的命令。因为所有这三个程序都使用UNIX正则表达式，因此书中用一章的篇幅来介绍UNIX的正则表达式语法。 然后，本书介绍如何编写sed脚本。从编写几行简单的脚本开始，学习进行手工编辑操作的其他基本命令和高级命令，以及由此引入的简单程序结构。这些高级命令包括用于处理保持空间、即一个等量齐观时缓冲区的命令。

In this second edition, the authors take account of the renaissance of dialect research in the last twenty years. They offer new sections on dialectometry and mapping variability, a revised section ...(展开全部)
