Re: [gdm-list] GDM session shutdown - how to execute an script before apps are killed.

[Ari El <ari reads gmail com>]

it didn't work :(

I did this:

ari copani:~$ cat /opt/azureus/azu-wrapper.sh
#!/bin/sh

trap 'killall -SIGHUP java' TERM INT QUIT

/opt/azureus/azureus
ari copani:~$ 


What I noticed is that, when the wrapper process is killed, Java and its
apps stay up!  So I guess, when Java receives a TERM, the wrapper does not
notice. 

So... another idea I had is to put the killall in the script that gets
executed when in GNOME menu I select System > Quit > (then I get this
mutibutton dialog, I'm using ubuntu feisty) Shutdown. Perhaps someone has a
clue about where this script is?

Thanks!
