How to unsuspend process after terminal session closed

Asked by Mannex

I have a shell script running and I ctrl-z to suspend it. Then, I restart the job in the background like %1 &. I later exit that terminal session. The job, of course, is still running. Now, I've opened a new terminal, and I would like to know if there is a way to bring it to the foreground. Since I am in a new terminal session, it is no longer listed as a job in jobs. I have the PID. Any ideas? Thanks.

thanks for the suggestions. Actually, these sound like great solutions, but not to my problem. I looked at the man pages for each of them and don't see a way to take a process ID of an existing running application and redirect it's output to my current tty. That's, in essence, what I'm trying to do.

did you try what marcobra suggested? or did you just look it up on manpages?

I tried various iterations, attempting to manipulate them into doing what I wanted to do. None of them seemed to work.

AFAIK, even though the process is running, once you've severed its connection to the terminal, there's no way to reconnect it.

You can get around this only if you've initially run the command under screen, nohup, etc. None of those will do any good for an already running process.

Sorry.

That was my suspicion, but I wanted to confirm. OK, thanks very much for your answer!
