通过本文的学习，您可以增加一些有用的设计实际正则表达式 (regexp) 的技能。构建正则表达式是任何管理员日常工作中的一部分。为了构造返回所需条件的成功正则表达式，需要学习以模式匹配的角度进行思考，而这种技能需要花大量的时间进行练习。

引言
UNIX® 管理员每天都需要构建和使用正则表达式 (regexp) 进行文本模式匹配。大多数语言都支持正则表达式的某种实现。有的应用程序（如 EMACS）具有正则表达式搜索功能，并且您可以通过各种命令行工具使用正则表达式。无论什么应用程序，构建正确的正则表达式的关键之处在于，识别仅满足需要匹配的数据的模式，以便在输入中排除其他不必要的内容。
出于这个目的，本文将逐步介绍几种正则表达式模式构建技巧，并介绍它们如何帮助您完成各种常规任务。
