Overview

W window has a _NET_WM_PID property set by the applicaiton. To really validate if the application has set this correctly is more work (see reference).

Simple Example

Run command and click the window

$ xprop _NET_WM_PID
_NET_WM_PID(CARDINAL) = 11524

Get process info

$ ps -p 11524 -f
UID        PID  PPID  C STIME TTY          TIME CMD
a211278l 11524     1  1 11:10 tty2     00:00:06 /usr/bin/gnome-system-log
