i have installed rootsh too.
and i can get root-access to my files via "sudo gainroot" in xterm.

but my problem is following:
i have a script and a desktop-shortcut to this script.

and now i have to execute this script with root-rights.
so how can this be done?

do i have to write something special after Exec= in the desktop-file?
do i have to write something special before the critical commands in the script?
what do i have to do!? i've tried so many things till now - nothing worked
