From: Will Martin <WMartin@office-3> Hi! In TENEX, there is a handy feature whereby a user at one terminal can request a "link" to another user's job. If this is not refused, each terminal displays the system output directed to either one. This is handy for training and jointly displaying the same data in two different sites. Is there a simple way to do this under UNIX, so that, for the remainder of a session or until it is terminated, all the output going to my terminal is simultaneously directed to a number of other terminals? We are thinking about using this for teleconferencing, and would want eight or so jobs linked together, so that one user is the controller, and determines what the others will see. I have thought about redirecting output to multiple devices using a tee command with the device name files. Is this the best way to do this (assuming it would work in the first place)? We would have to set up a little shell script to replace "cat" with some term which incorporated all the redirection, but that shouldn't be a problem. I'd prefer something that would be transparent after starting it up, though, if it were possible. Any advice? Regards, Will Martin
