A Radarr post processing script to remove the video file from packed torrents, modified version of subzero79/87a347a07964390884c9
#!/bin/bash
# Examples for testing
# radarr_moviefile_sourcefolder="/data/torrent/movies/Justice.League.2017.1080p.HDRip.X264.AAC-m2g" radarr_moviefile_sourcepath="/data/torrent/movies/Justice.League.2017.1080p.HDRip.X264.AAC-m2g/Justice.League.2017.1080p.HDRip.X264.AAC-m2g.mkv"
# Instructions
# Put this script somewhere on your file system like /usr/local/bin and make it executable.

# In Radarr, Settings -> Connect add a Custom Script

Been loving this script for many months now, but I'm thinking it needs a little tweaking that is above my scripting knowledge. If a non-RAR file is downloaded and not placed into a subdirectory, this script purges the video file. Resulting in errors in my seeds. It's a simple fix. Copy the file back, rename it, and force recheck it. But it's a little time consuming. Would it be possible to add some check that both the RAR and video file need to exist before processing? Or a way to skip if only a video file that was not placed into a sub directory? Sonarr has the same problem from time to time too.

That is what line 56 is trying to do, it should be causing it to not run on torrents not in a folder. Torrents that are single file. Do you have your torrent client setup to use the original torrent format or does it force single file torrents to not be in folders?

But really, you should move to unpackerr, it does everything correctly. Including removing the video file after import.

I saw that line after I posted. Completely missed it the first pass. I'm running deluge and to my knowledge I don't have anything special set. It does retain the same format. The only forcing may be due to the "extractor" plugin, which is set to "create torrent name sub-folder". But without this, radarr or sonarr won't import/move the file into place. Thinking a little more, maybe the extractor plugin is the issue and not this script. Although the script is the only piece that I know would delete a file.

I will have to look into unpackerr. I mentally can't wrap my mind around how it will work yet as I know the other xxxarr dockers monitor their respective download location.

EDIT: So am I correct in that I just need to disable the extractor plugin within Deluge and have unpackerr do the monitoring?

Yeah, if you switch to unpackerr you would disable this cleanup script and disable any unpacking plugin in Deluge.

It's running through my entire /downloads/ directory and unpacking everything. Is that normal for the first use? It's been less than 5 minutes, which is what the default delete delay appears to be. But did I just create a mess I need to clean up for everything that was existing?

It should only unpack things that show up in Activity in sonarr/radarr if you set it up right. Did you point it at sonarr/radarr? Or did you point it at a folder? Also, switch to unpackerr's Discord. :)

Thanks for the help and sorry to get off topic. I think I figured out the issue. Sonarr/Radarr had a hiccup on some imports and re-queued things that had already been done and processed. Being back in the queue, unpackerr picked them up. Cleaning up my queues now. Thanks again for the pointer to this docker/app.
