Tvheadend

Hello!
I need to stop recording tvheadend from a terminal or bash script. I do not know what command to stop recording, but I can stop all tvheadend. I need to first stop the recording and then stop tvheadend.

To stop tvheadend use the command
systemctl start service.multimedia.tvheadend.service
To stop tvheadend use the command
systemctl start service.multimedia.tvheadend.service

The above commands work great, but I need to stop the recording.

Thanks.
