Hi. I'd like to add a new icon to lxde desktop, that has associated with it the
name of a shell script (that i've written) or single command, so that when i
double-click the icon, the script/command executes.

Could you tell me how to do it please? I've looked in knoppix wiki but can't see
it covered.

I guess this kind of question would be covered by a Knoppix manual. Where would
I find such an online manual or book i can buy please? Also, I know that there
is documentation within knoppix itself, like "KDE Help Centre", but it doesn't
seem to contain instructions for doing things in the desktop environment, like
this query that i have here.

Thanks, John.
