I was surprised at the first moment, too, but I think the answer is in first paragraph of the man page: PATTERNS is one or more patterns separated by newline characters, and grep prints each line that matches a pattern. Thus, grep $'a\nb' find all lines that either contain an a or a b. Best regards Martin
