--exclude-dir = DIR:匹配一个目录下的很多内容同时还要让一些子目录不接受匹配,就使用此选项。 --include = GLOB:仅搜索其基本名称与GLOB匹配的文件(使用--exclude下所述的通配符匹配)。 -R ,-r:以递归方式读取每个目录下的所有文件; 这相当于-d recurse选项。 其他选项: --line-buffered:在输出上使用行缓...

一、命令介绍 grep命令是文本搜索命令,它可以正则表达式搜索文本,也可从一个文件中的内容作为搜索关键字。grep的工作方式是这样的,它在一个或多个文件中搜索字符串模板。如果模板包括空格,则必须被引用,模板后的所有字符串被看作文件名。搜索的结果被送到标准输出,不影响原文件内容。语法:grep[option] pattern...

Subdirectories are not excluded by this option; they are searched recur- sively, subject to the --exclude-dir and --include_dir options. The pattern is a PCRE regu- lar expression, and is matched against the final component of the file name (not the entire path). If a file name ...
