As I suspected, the behavior of Linux utils on these two commands is different. In both cases, cat reads data from stdin *twice*, expecting two ^D presses to finish successfully. On the other hand, the two commands shown above, behave exactly like FreeBSD when they are executed in Solaris 7 running on a sun4u machine that I could ssh to. Ok, now I really need some sleep and a cup of strong black coffee. Or someone to point me in the correct direction, be it "you are wrong for [this] and [that] reason", or "hmmm, this is truly weird, fix it yourself and make it behave [this] or [that] way and send us a patch". -giorgos To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
