Thanks to the powerful RPC, transmission-remote can talk to any client that has the RPC enabled. This means that a script written using transmission-remote or RPC can, without rewrite, communicate with all the Transmission clients: Mac, Linux, Windows, and headless.
macOS users may wonder whether there will be AppleScript scripts, the answer is ''no''. Although AppleScript is a nice technology, it's a pain to implement. However, macOS is a Unix after all, so any script you find here will also work on macOS. Even from within AppleScript, you can run these scripts by typing: do shell script "path/to/script".
If you are interested at writing scripts for Transmission, have a look at the following pages:
For those who need more information how to use the scripts, have a look at the following links:

Transmission can be set to invoke a script when downloads complete. The environment variables supported are:
TR_APP_VERSION- Transmission's short version string, e.g.4.0.0TR_TIME_LOCALTIMETR_TORRENT_BYTES_DOWNLOADED- Number of bytes that were downloaded for this torrentTR_TORRENT_DIR- Location of the downloaded dataTR_TORRENT_HASH- The torrent's info hashTR_TORRENT_IDTR_TORRENT_LABELS- A comma-delimited list of the torrent's labelsTR_TORRENT_NAME- Name of torrent (not filename)TR_TORRENT_TRACKERS- A comma-delimited list of the torrent's trackers' announce URLs
Here is an example script that sends an email when a torrent finishes.
Functionality of these scripts has been implemented in libtransmission and is thus available in all clients.
Tomas Carnecky (aka wereHamster) is maintaining a set of scripts in his GitHub repository.
Oguz wrote on his blog a PHP script to stop Transmission after it finishes downloading and seeding. Scripts which have not yet been ported and may not work with the latest version:
- https://pastebin.com/QzVxQDtM: Bash - (cron)script to keep a maximum number of torrents running; starting and pausing torrents as necessary
- https://github.com/jaboto/Transmission-script - (cron)script set network limits according to the number of clients in the network
transmission-daemon's packaging has many permissions disabled as a standard safety measure. If your script needs more permissions than are provided by the default, users have reported that it can be resolved by changing to NoNewPrivileges=false in /lib/systemd/system/transmission-daemon.service.
