I want to launch an app in a separate X server. It needs a window manager behind it, though.

I created a script 

#!/bin/sh
x-window-manager &
my-gui-app

and launched it with 

xinit myscript.sh -- :1

The problem is: even after closing the app, the window manager keeps running. I want it to quit after my-gui-app exits.

Is it possible to achieve it?

Try to add a last line kill %1 In interactive shells at least you can kill the pid of the background job this way. Otherwise look if the process can write a pid file or use killall, if you're sure, there's only one process of this wm

kill -TERM -$$ (kill current process group) should also do it in a race condition-safe manner.

This or kill % should be preferred to killing by pid or by name.

  • Killing the process group might kill parents of the script, depending on how it was started. If you want to use process groups here, use `setsid` or otherwise ensure that the shell runs in its own process group. – Gilles 'SO- stop being evil' Aug 02 '15 at 18:29
