Running this script manually from the terminal, I get an error:

transmission_remove_finished.sh: 18: transmission_remove_finished.sh: Syntax error: "(" unexpected<

Any idea what I may be doing wrong?

#!/bin/bash
HAUGENE_ID=`/usr/bin/docker ps | grep "haugene" | awk '{print $1}'`
docker exec -e tmpUser=$RPC_U -e tmpPass=$RPC_P $HAUGENE_ID /shared/remove_finished

Most likely it was:

/shared/remove_finished_torrents

The script also applies to Transmission (vanilla):

#!/bin/bash
TRANSMISSION_ID=`/usr/bin/docker ps | grep "transmission" | awk '{print $1}'`
docker exec -e tmpUser=$RPC_U -e tmpPass=$RPC_P $TRANSMISSION_ID /shared/remove_finished_torrents

PS. For me it was crontab -e

Most likely it was:

/shared/remove_finished_torrents

Good catch. This was a typo. I just corrected it in the original comment.

Glad it works for you. I've had this script running on my setup for roughly 2 years without issue.

Ah yes, I copied the terminal output after the fact (crontab -l) rather than document how to actually edit it. 🙃
