I see, thanks. So I was sending it four values apparently. I did not
understand the error message.

I intend to use this in a Dolphin (KDE file manager) service menu
only. But I will try to be careful about that in the future. Running
the script in $HOME might be interesting!
Actually, I will add a check that cwd != $HOME || $HOME/.bin as those
are the only likely places it might run by accident. Or maybe I'll
wrap it in Qt and add a confirm button.

I did see that while googling, but did not understand it. Nice!

I am testing on fake data, naturally.
Thanks!
