The spec file is a way that RPM based distros like Fedora/Mandrake/Suse can create a rpm file. Since you are running Kanotix, a derivattive of knoppix/debian, you can safely ignore that .spec file.

Code:
find ./ -name '*.sh'
That should show you where the scripts are. I know for a fact that at least 1 script is in the icons folder. If the scripts are not executable, then
Code:
chmod u+x scriptname.sh
will set the execute permissions flag on the script.
