  Verbose output (can be used many times to increase verbosity level).

  Quiet output, check success or failure is set in return code.

- **-n**

  Do not check data (useful with -i option and default with -l).

- **-z**

  Fill missing data with zeros when checking (this forces hash computation).

- **-i**

  Show the content of the given torrent file. This includes the files list with their size, the tracker announce, the torrent hash value.

  List filenames with size of the given torrent file and don't check data.
