Yes, I know that "grep(1)" only promises that "-m" works "If the input is standard input from a regular file", but IMHO we would all benefit from having an option for "grep" (and "head") that would force using "read(fd,&c,1)" when the user really, really wanted it (them) to. -Rob ----- Rob Warnock <rpw3@rpw3.org> 627 26th Avenue <URL:http://rpw3.org/>; San Mateo, CA 94403 (650)572-2607
