Is there an easy way to transfer nohup process which has been spawned by a parent no longer alive, between ttys? I am not sure how clearly, I have expressed myself. Let me try again. Suppose I leave an emacs process running, and exit. If I login as a new tty, is there a way to get back into my emacs process? Please send e-mail. Thanks! Asim Jalis.

There is a program caled "screen" which is freeware and runs only ony BSD flavors of Unix. If you hangup during a screen session, logging back in allows you to reattach to the screen's child processes. This is an added feature of "screen"; it's not its main purpose. Its main purpose is to have virtual screens on a simple tty. -- Tom Reingold tr@samadams.princeton.edu rutgers!princeton!samadams!tr 201-560-6082

This "feature" is no longer available in newer releases of "screen" -
however I can't say that I really miss it. Most interactive things can be
saved and restored later, and processes that I want to nohup and let run, I
usually mail the output to myself. As a further note, I believe "screen"
also caused the child to block on output if the parent had disconnected.
This was not optimal in my opinion and was one reason I considered it to be
a less-than-valuable function.
