Usage

usage: torrent-edit [-h] [--public | --private] [--add URL [URL ...]] [--remove URL [URL ...]] [--replace URL [URL ...]] [-v] torrent

Edit BitTorrent metadata (private flag and trackers).

positional arguments:
  torrent               Path to the .torrent file(s)

options:
  -h, --help            show this help message and exit
  --public              Remove the private flag
  --private             Set the torrent as private (disable DHT/PEX)
  --inplace             Modify the torrent inplace even if the hash has changed instead of recreating it
                        (if the privacy flag has been toggled)(not recommended)
  --resume_path [RESUME_PATH]
                        Directory of the .resume or .fastresume file(s). Used for qBittorrent and Transmission.
  --add URL [URL ...]   Add all trackers with the provided list
  --remove URL [URL ...]
                        Remove all trackers with the provided list.
                        If no tracker is found, the file will be skipped, even if private is set.
  --replace URL [URL ...]
                        Replace all trackers with the provided list
  -v, --verbose         Enable verbose output (debug logging)

Examples

You can specify multiple files:

$ torrent-edit *.torrent [...]

• Make a torrent private / public

$ torrent-edit "Mr.and.Mr.Macron's.holidays.financed.by.your.taxes.mkv.torrent" --private

This sets the private flag in the torrent metadata. Most BitTorrent clients will disable DHT, PEX, and LSD when the torrent is private.

$ torrent-edit movie.torrent --public

Removes the private flag.

⚠️ Notice: By doing this, you are changing the torrent's hash. The file will therefore be different for the network, and your old peers will no longer be able to find you. However, you may have two torrents pointing to the same file, and the hash obtained is exactly the same as the hash that would have been obtained if the torrent had been generated from the start with this option.

⚠️ Notice: When doing this, you may need to update the path to the file in your application. This is because the torrent client treats it as a new pending download. To AVOID this, use the --resume_path parameter that points to the .resume or .fastresume files of Transmission or qBittorrent. The updates will be made automatically and visible once the client is restarted.

Use the --inplace parameter to force editing the torrent file in place (even if the hash is modified). This can be useful if you are working with torrents that not already loaded in a BitTorrent client.

• Add a tracker

$ torrent-edit movie.torrent \
    --add https://tracker/announce

You can specify multiple trackers:

$ torrent-edit movie.torrent \
    --add \
    https://tracker1/announce \
    https://tracker2/announce

• Remove a tracker

$ torrent-edit movie.torrent \
    --remove http://oldtracker/announce

• Replace all trackers

$ torrent-edit movie.torrent \
    --replace \
    https://tracker1/announce \
    https://tracker2/announce

This removes all existing trackers and replaces them with the provided ones.

How to use in real life (GNU/Linux)

• Stop the BitTorrent service or application (Transmission, qBittorrent, etc.)

• Find the directory with the torrents used by your application, and go into it.

  • For Transmission server: /var/lib/transmission-daemon/info/torrents/ (torrents), /var/lib/transmission-daemon/info/resume/ (resume files)

  • For Transmission client: ~/.config/transmission/torrents/ (torrents), ~/.config/transmission/resume/ (resume files)

  • For qBittorrent (Linux): ~/.local/share/qBittorrent/BT_backup/ (torrent & fastresume files)

  • For qBittorrent (Windows): %LOCALAPPDATA%/qBittorrent/BT_backup (torrent & fastresume files)

• Execute the script with your own arguments.

• If you are using a simple client, just restart it, it's done.

• If you are using Transmission server, you may have to restart the service and reload the torrents with the remote administration tool.

sudo find . -iname "*.torrent" -exec transmission-remote 127.0.0.1:9091 -n transmission_login:transmission_pass -a {} \;

Done!

Alternative

The tool transmission-edit allows you to update the tracker list, but will NOT allow you to toggle the private flag.

Example:

cd /var/lib/transmission-daemon/info/torrents
sudo transmission-edit -r "old_url" "new_url" *.torrent
