[arch-general] wmctrl doesn't show the PID of all windows

[Ralf Mardorf]

Hi,

wmctrl could fail, if I want to get the PID that belongs to a window?
assumed I want to kill just one instance of xfw, how could I e.g. get
the PID of the xfw windows?

[rocketmouse at archlinux ~]$ ps aux|grep -v grep|grep xfw
rocketm+ 28733  0.2  0.3 126964 13836 pts/4    S+   14:25   0:00 xfw
root     28734  0.0  0.1  72312  5216 pts/3    S+   14:26   0:00 sudo xfw
root     28735  0.2  0.3 127744 14220 pts/3    S+   14:26   0:00 xfw
