linux - grep，但只有特定的文件扩展名(grep, but only certain file extensions)

Question

I am working on writing some scripts to grep certain directories, but these directories contain all sorts of file types.

(我正在编写一些脚本来grep某些目录，但这些目录包含各种文件类型。)

I want to grep just .h and .cpp for now, but maybe a few others in the future.

(我想grep只是.h和.cpp现在，但也许其他几个人的未来。)

So far I have:

(到目前为止，我有：)

{ grep -r -i CP_Image ~/path1/;

grep -r -i CP_Image ~/path2/;

grep -r -i CP_Image ~/path3/;

grep -r -i CP_Image ~/path4/;

grep -r -i CP_Image ~/path5/;} 

| mailx -s GREP [email protected]

Can anyone show me how I would now add just the specific file extensions?

(任何人都可以告诉我如何添加特定的文件扩展名？)

Answer 1

Just use the --include parameter, like this:

(只需使用--include参数，如下所示：)

grep -r -i --include *.h --include *.cpp CP_Image ~/path[12345] | mailx -s GREP [email protected]

that should do what you want.

(应该做你想要的。)

Syntax notes:

(语法说明：)

• -r - search recursively

  (-r - 递归搜索)

• -i - case- insensitive search

  (-i - 不区分大小写的搜索)

• --include=\*.${file_extension} - search files that match the extension(s) or file pattern only

  (--include=\*.${file_extension} - 仅搜索与扩展名或文件模式匹配的文件)
