To run applications from gnome, users click on icons on their desktops or they select the applications which they want to run from a menu.
I'm looking for a valid replacement pattern, to get the current user within a desktop file.
[Desktop Entry]
Name=FooCorp Painter Pro
Exec=/run/media/%%USER_NAME%%/foocorp-usb-stick/foocorp-painter-pro
Icon=foocorp-painter-pro
Type=Application
Categories=GTK;GNOME;Utility;
