I just finished going through a couple of crontabs prepending the command-lines with ``exec'', when it hit me. Can shell itself recognize, there will be no more commands and just proceed to exec without forking? What would this break? This should never, of course, happen in interactive mode... The shell's source requires studying, but, may be, a knowledgeable person can answer right away? -mi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
