If you invoke functorrent without any options, it expects the contents of a torrent file
to be given in stdin. So
-$ cat ubuntu-14.10-desktop-amd64.iso.torrent | functorrent
-[....]
+ $ cat ubuntu-14.10-desktop-amd64.iso.torrent | functorrent
+ [....]
Or one can explicitly specify the torrent file as input.
-$ functorrent ubuntu-14.10-desktop-amd64.iso.torrent
-[...]
+ $ functorrent ubuntu-14.10-desktop-amd64.iso.torrent
+ [...]
