No no. Syslog receives the message and then pipes it to the command, "read" in the shell script reads it's standard input, hence it gets the data from a pipe the shell invokes. It has nothing to do with terminals. If this were not the case the whole pipe-command mechanism of syslogd would never work. -- Regards Cliff Sarginson -- <csfbsd@raggedclown.net> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
