And I would argue that the fdescfs is cleaner than the '-' hack. (Which, by the way, should not be considered a filename hack so much as a command-line-parameter hack; since it was invented before there was a way to say 'use stdin/stdout' on the command-line... You could think of '/dev/stdin' as "'-' version 2") -Pat To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
