Better, apparently to "copy" (not actually), rather than to whine in the background... Still - your response is equally ignorant (Plan 9 is well known - even to students), since it offers no useful information. The /proc stuff is used in "real" Unix's such as Solaris. Just checking, I see that FreeBSD implements procfs, which is along the same lines. (still waiting for FreeBSD to "complete" a sysinstall program that doesn't look as if it was an assignment for high-school interns). -- T.E.Dickey <dickey@herndon4.his.com> http://invisible-island.net ftp://invisible-island.net
