Pre-Logout Script

[Mike Perry]

Hey,

>From the looks of your script you are sending a SIGTERM which is causing
vmplayer to suspend. Kind of odd that when it gets a SIGTERM it is
suspending, but acting different on a SIGHUP.

When you launch vmplayer you can easily ignore the HUP with the 'nohup'
command. If it is a gui application, I'm not too certain how it will handle
that though. What may be better is to make a launch script that traps
SIGHUP and upon receiving it sends a SIGTERM to the vmplayer pid instead.
Maybe something like:

#!/bin/bash

trap 'kill -TERM $_CHILD' HUP
nohup /path/to/vmplayer $* &
_CHILD=$!

wait $_CHILD

I dunno, just a thought.

If you come up with something else you could probably simplify your
shutdown script by using 'pidof' or 'pgrep'

Cheers
