For rTorrent users, this bash script will extract the original .torrents corresponding to all or a part of the active torrents. The .torrents will be created in an output directory with a subdirectory structure identical to the one used for downloads.
This can be usefull to migrate a great number of active torrents to another bittorrent client, or to store the .torrent file besides their download.
To install, just download to your preferred location, make executable, and edit to modify the default paths at the first lines of the script:
- SessionDir is the .sessions directory as defined by the session= directive in .rtorrent.rc
- DownloadDir is the base directory for torrent downloads as defined by the directory= directive in .rtorrent.rc
- OutputBaseDir is the base directory where the .torrent files are to be extracted. It will be created if it doesn't exist.
For each active torrent in rTorrent there are three files kept in the .sessions directory. The name of these files is an infohash that uniquely identifies the torrent (e.g.FA8B12944B7C615F13CD98B9D845116E01992E08), but it makes difficult to correlate them to the files downloaded:
- infohash.torrent is the original .torrent renamed.
- infohash.torrent.rtorrent is a bencoded file with info and status data about the torrent.
- infohash.torrent.libtorrent_resume is a bencoded file with info to resume download and/or seeding after each restart.
This script will extract bencoded data from the first two files, like original .torrent name, download name and path, tracker or label.
With that info it will get a "human" name for the .torrent, either the original one, or an alternative name based on the download name, which makes easier to associate .torrents with their downloads. Many times both names are identical. This alternative name will also be used in some rare cases where the saved original name is blank or the infohash.
It will also create a path for the .torrent that recreates the same directory structure used for downloads (if one exist). For example, if a torrent download is located at /downloaddir/films/HDB/ the corresponding .torrent file will be created at /outputbasedir/films/HDB/.
If you make OutputBaseDir=DownloadDir and use the -a option your .torrents will be created in the same directory and with the same name that their downloads. This can be a convenient way of saving .torrents to recover from session corruptions.
The extraction can be filtered by tracker or label.
Usage: extract_torrents.sh [OPTION]...
This script will extract infohash.torrents from the .session directory, rename them to their original name (or optionally like the downloaded files).
The extracted .torrents will be copied to a base output directory with the same subdirectory structure than their downloaded files.
-a Use an alternative name for the .torrent based on the downloaded
filename or directory (for multi-file downloads).
This makes easier to associate .torrents and downloads.
-x Execute the commands. Without this switch the script will only
show the commands without executing them.
-t TRACKER Extract only .torrents from TRACKER. Use the tracker name as it
appears in rutorrent (i.e. hdbits.org apollo.rip ....)
-l LABEL Extract only .torrents that have that specific rutorrent label.
-s PATH Full path of the .session directory including trailing slash.
Default: "$SessionDir"
-d PATH Full path of the Download base directory including trailing slash.
Default: "$DownloadDir"
-o PATH Full path of the Output base directory including trailing slash.
Default: "$OutputBaseDir"
