If your grep supports -R, do:

如果您的grep支持-R，请执行:

grep -R 'string' dir/

If not, then use find:

如果不是，则使用find:

find dir/ -type f -exec grep -H 'string' {} +

grep -r -e string directory

-r is for recursive; -e is optional but its argument specifies the regex to search for. Interestingly, POSIX grep is not required to support -r (or -R), but ~~I'm practically certain that System V grep did, so~~ in practice they (almost) all do. Some versions of grep support -R as well as (or conceivably instead of) -r; AFAICT, it means the same thing.

- r是递归;-e是可选的，但它的参数指定要搜索的regex。有趣的是，POSIX grep不需要支持-r(或-r)，但是我几乎可以肯定System V grep会支持-r，所以实际上它们(几乎)都支持。一些版本的grep支持-R以及(或可以理解地代替)-R;它的意思是一样的。
