How to check from console if a Torrent is complete ?

I have a few torrents running on my desktop machine.

I would like to know if a torrent is complete, from my netbook and
preferably without connecting graphically.

I was thinking along the lines of finding the presence or absence of some
file in ktorrents directory under ~/.kde4.

Has anyone ever tried this? I didn’t find anything yet, but I wouldn’t want
to spend hours comparing dirs if there is a simple solution.


When in doubt, use brute force.
