screen -r spawning new prosses

  • 772

I'm new to screen and I'm trying to figure out how to detach from a session and reattach later. So far I've tried:

$screen
C-a z (within screen to detach)
$screen -r

So far so good but when I C-a z to detach again, I see 2 screen processes running:

$ps
  PID TTY           TIME CMD
33145 ttys000    0:00.06 -bash
33176 ttys000    0:00.01 screen
33407 ttys000    0:00.01 screen -r

If I detach and reattach again I get another screen process, etc...

So, how can I reattach to the screen session without spawning a new process?

Thanks!

  1. Try to detach within a screen:

    ctrl a d

    to reattach:

    screen -rd (detaches the screen first if was attached)

    There is also:

    screen -x (attaches the screen again, so you can watch the screen with two sessions)

    C-a z suspends your screen process. If your shell is bash, you can see the stopped process by running jobs and resume it with fg. Detaching is a different concept.

    To detach from a session, use C-a d. You will still see the screen process in your process list, and you can list it by running screen -ls. Resume with screen -r, but read the man page about the different ways to resume a running screen session.

    Congratulations on learning about screen! It's an amazing tool.
