I have many files I need to search for some string. I'm using
grep -rl 'pattern' * to find files that contain the pattern. However, I'm only interested in file count - if string occurs in more than N files, I want grep to stop immediately after hitting Nth match(as searching through the whole file hierarchy is long operation). It would be nice if it returned some meaningful exit code, but if that's impossible then I can just pipe it to
wc without a problem.
How can I tell grep to stop searching other files after matching Nth file?
