Can anybody tell me how in general to grep files for hex characters 00 to ff inclusive? I can do the 26 characters 01 to 1a (being ^A to ^Z respectively) and also 20 to 7e (being <space>, punct, 0-9, A-Z, more punct, a-z, more punct) but am stuck for everything else: 00, 1b to 1f and 7f to ff. Dunno, I thought it might be something like
find . | xargs grep -l "\x8f"
but it's obviously not that. Thanks. (Maybe I can use sed just to find stuff, not replace it?)
