Thanks qwerty12 (Faheem),
However, I tried your suggestion, and chmod still doesn't work for me.

I opened my *.sh files using Leafpad on the n810 and added the line you suggested: #!/bin/sh

I then did a "Save As..." for each file using Leafpad then copied the files into the /home/user/MyDocs folder as above. After that, when I did "chmod +x *.sh" for each of the files, nothing happened. I tried installing my GLaunch.desktop file (using Type=Application) into /usr/share/applications/hildon--but, when I tapped the icon in Extras, there was no response, not even an error message.

I appreciate any help!
