Delete and remove files for any seeding torrents that have been idle for some number of days

transmission-cleanup.py

import datetime
import transmissionrpc

from config import TRANSMISSION

daemon = transmissionrpc.Client(
    address=TRANSMISSION.server,
    port=TRANSMISSION.port,
    user=TRANSMISSION.user,
    password=TRANSMISSION.password)

for torrent in daemon.get_torrents():
    if torrent.status == 'seeding':
        idle_time = datetime.datetime.now() - torrent.date_active
        if idle_time > datetime.timedelta(days=2):
            print 'Removing %s after %s inactivity' % (torrent.name, idle_time)
            daemon.remove_torrent(torrent.hashString, delete_data=True)

Example setup:

1. Ensure that rpc-enabled is set to true in your transmission-daemon config and that RPC is up and running (if you have something like Sonarr using it, you're all set already)
2. Put this file in its own directory somewhere safe like /home/tvrobot/transmission-cleanup/run.py
3. Install the transmission library into the system python: sudo easy_install transmissionrpc
4. Add your transmission details in a file named config.py in the same directory:

class SETTINGS:
    days_to_wait = 10

class TRANSMISSION:
    server = '127.0.0.1'
    port = '9091'
    user = 'hellorobot'
    password = ''

• days_to_wait: once a torrent has been active for this long, delete it
• server: use this for default or whatever value you've set in transmission-daemon config's rpc-bind-address
• port: transmission-daemon config's rpc-port
• user: transmission-daemon config's rpc-username (leave blank if rpc-authentication-required is false)
• password: transmission-daemon config's rpc-password if set, otherwise leave blank

5. Check where your python is installed with which python
6. Edit your crontab to add a schedule with sudo crontab -l
7. Ensure that the PATH includes your python location (add it if missing), looking something like PATH=/usr/sbin:/usr/bin:/sbin:/bin
8. Add an entry to run the cleanup, for example this runs it every night at 1am:

  0 1    *   *   *   python /home/tvrobot/transmission-cleanup/run.py
