The desktop shortcut doesn't show you anything because the script was meant to be running from the X-Terminal. If you run it from there you will see that it tells you when it is finished. However, I think your N900 it is not running it because the screen always shows signs of restarting.

I did not post the desktop shortcut, it was an attribution from one of the members. The script needs to be edited to show outputs if you are going to use it like that. I'm not interested in making something like that, I'm more interested in adding a shortcut to the systemui and I will work on that later, first I'm testing other stuff because the script seems to be mature enough like it is
