Well, I think that if you keep appending to a zipped archive you have
to unzip it, add the something and rezip it, so that becomes quite the
computative burdon.
Look at the -v option of bzip and see if that'll help you get a progress
bar. I would think you could at least put up a cylon-mode 'progress is
being made' bar.
How are using kdialog? No man page :(. Nothing in
/usr/share/doc/kdebase-bin/ :(. Nothing comes up when searching the KDE
manual :(.
BTW, you also might want to add a -p to your cp.
