grep -R "string" /directory/

当-R不跟随符号链接时，-R也跟随符号链接。

下面的示例递归地查找位于文件夹path1、path2和path3中的*.xml和*.js文件中的搜索字符串。

grep -r --include=*.xml --include=*.js "your search string" path1 path2 path3

因此，您可以在文件的子集中搜索许多目录，只需在最后提供路径。

我喜欢使用的另一个选项:

find folder_name -type f -exec grep your_text  {} \;

-type f只返回文件而不返回文件夹

-exec and{}在搜索中找到的文件上运行grep(准确的语法是“-exec command{}”)。

grep -nr 'yourString*' .

末尾的点搜索当前目录。每个参数的含义:

-n            Show relative line number in the file
'yourString*' String for search, followed by a wildcard character
-r            Recursively search subdirectories listed
.             Directory for search (current directory)

grep -nr 'MobileAppSer*'。(会找到MobileAppServlet.java或MobileAppServlet.class或MobileAppServlet.txt;“MobileAppASer *。*'是做同样事情的另一种方式。)

需要查询更多参数，使用man grep命令。

Grep -r "yourstring" * 会发现“你的字符串”在任何文件和文件夹

现在，如果你想同时查找两个不同的字符串，你可以使用选项E并为搜索添加单词。休息之后的例子

grep -rE "yourstring|yourotherstring|$" *将搜索yourstring或yourotherstring匹配的列表位置

还有:

find directory_name -type f -print0 | xargs -0 grep -li word

但这对初学者来说可能有点多。

find is a general purpose directory walker/lister, -type f means "look for plain files rather than directories and named pipes and what have you", -print0 means "print them on the standard output using null characters as delimiters". The output from find is sent to xargs -0 and that grabs its standard input in chunks (to avoid command line length limitations) using null characters as a record separator (rather than the standard newline) and then applies grep -li word to each set of files. On the grep, -l means "list the files that match" and -i means "case insensitive"; you can usually combine single character options so you'll see -li more often than -l -i.

如果您不使用-print0和-0，那么您将遇到包含空格的文件名的问题，因此使用它们是一个好习惯。
