Recently, I’ve tried to download a torrent containing several individual files using bittornado and the download stalled at something like 99%, so I needed to check, which of the individual files were downloaded completely. An apt-get search lead to cfv, a versatile file checksum creator and verifier.

$ sudo apt-get install cfv
$ btshowmetainfo foo.torrent

You now get the torrent’s contents listed, cd into the directory containing the listed files.

$ cfv -f foo.torrent

The files are now checked, and the incomplete files will be listed.
