linux - 如何递归grep？(How do I grep recursively?)

Question

如何递归grep所有目录和子目录？

find . | xargs grep "texthere" *

  ask by wpiri translate from so

Answer 1

grep -r "texthere" .

The first parameter represents the regular expression to search for, while the second one represents the directory that should be searched.

(第一个参数表示要搜索的正则表达式，而第二个参数表示应搜索的目录。)

In this case, .

(在这种情况下， .)

means the current directory.

(表示当前目录。)

Note: This works for GNU grep, and on some platforms like Solaris you must specifically use GNU grep as opposed to legacy implementation.

(注意：这适用于GNU grep，在某些平台（如Solaris）上，必须专门使用GNU grep而不是传统实现。)

For Solaris this is the ggrep command.

(对于Solaris，这是ggrep命令。)
