As noted in comment to other answer, this will fail to detect a string that happens to fall on a fold boundary. But if you run grep with a few different strings - `grep "string1|string2|string3" - chances are probably slim all three are always falling on a fold boundary, so you'll still find what you're looking for.

--mmap is only available in BSD grep, but Linux uses GNU grep
