[Ilugc] attach a process to terminal

[Ashish Verma]

Hi,

I had started a rsync process in the bg and then happened to close that
terminal. Now that process shows a S status in ps and is not working.

>From what I found out, this is because the process has been disconnected
from the terminal that started it. I could not locate a way to attach it to
some other terminal and restart it. Is there a way to do this. I mean can
the process be restarted in any way or connected to another terminal?

Regards,
Ashish

But then, the process should have been started in screen. I started it
directly in a pty and closed that pty.

Is there no way to restart it without reattaching it. Or opening a new pty
which is now of the same number as the closed one and doing something to
attach the process to the new pty.

Ashish

The process has to be started in screen in order to re-attach.

I don't know about re-attaching, however if all that you want is to run process 
even after closing shell or logout, you may use nohup.
e.g
$ nohup myprog &
In this case myprog will run even if you log out.

AFAIK, this is simply not possible.

You could kill the process and start it again in daemon mode:

# rsync --daemon
or
# rsync -d

How about sending SIGHUP to that process ?

I think screen might be an overkill for this
