I have written a shutdown script for transmission. Transmission calls the script after a torrent download finishes. The script runs perfectly on my machine (Ubuntu 11.04 & 12.04).

#!/bin/bash

sleep 300s



# default display on current host

DISPLAY=:0.0



# find out if monitor is on. Default timeout can be configured from screensaver/Power configuration.



STATUS=`xset -display $DISPLAY -q | grep 'Monitor'`

echo $STATUS



if [ "$STATUS" == "  Monitor is On" ]



###  Then check if  its still downloading a torrent. Couldn't figure out how.(May be) by monitoring network downstream activity? 



then



    notify-send "Downloads Complete" "Exiting  transmisssion now"

    pkill transmission



else

    notify-send "Downloads Complete" "Shutting Down Computer"

    dbus-send --session --type=method_call --print-reply --dest=org.gnome.SessionManager /org/gnome/SessionManager org.gnome.SessionManager.RequestShutdown



fi



exit 0

The problem is that when I'm downloading more than one file, when the first one finishes, transmission executes the script. I would like to do that but after all downloads are completed.

I want to put a 2nd check ( right after monitor check) if it is still downloading another torrent.

Is there any way to do this?
