Help with post completion unrar script about docker-transmission HOT 5 CLOSED

1. The script simply needs to be readable by your container user ( the uid and gid you set when launchng) and executable so

chown youruid:yourgid yourscript.sh
chmod +x

Is enough

2. This is an alpine image meaning find is just a symlink to a static binary with many linux utilities called busybox. execdir is not available and adding it will never be planned (containers are supposed to run one app not be a full linux environment)

modify your script to something like this:

#!/bin/bash
cd ${TR_TORRENT_DIR}/${TR_TORRENT_NAME}
unrar e -o- *.rar

There is no need to use find in this example as you are not actually looping through results you just want to unrar anything with the file extension .rar .

3. You need to stop and take a hard look at the permissions of your bind mounted /downloads folder and the accompanying files inside of it.

On your HOST run:

ls -n

this should output lines like this:

drwxr-xr-x  10 1000 1000 4096 Jan 11 14:50 downloads

where 1000 is your UID and 1000 is your GID.

Make sure you are not only running the container as this UID and GID (options -e PGID= -e PUID=) but that on your host you chown the parent directory and all subdirectories to this user.

chown -R 1000:1000 /your/directory/here

If you are running windows, good luck.

thanks for ur help

So this might end up being more a a feature request/discussion

I've scoured the interwebz and figured out the best unrar script for post completion:

#!/bin/bash
find ${TR_TORRENT_DIR}/${TR_TORRENT_NAME} -name '*.rar' -execdir unrar e -o- {} \;

Works perfectly with a transmission-daemon on it's own.

I had 3 issues with this on docker:

1. couldn't figure out the best way to add the script. so i ended up putting it in the config folder, but is still had perms issues so i chmod 777 and it worked. i would imagine there is a better way
2. the version of find in the container is old(?) or custom(?), not too sure. but i do know that it s does NOT have the -execdir option, which i think might be necessary to keep the unpacked file in the correct dir. i tried using -exec option which i think leads to #3
3. permission denied when extracting:

UNRAR 5.40 freeware      Copyright (c) 1993-2016 Alexander Roshal

Extracting from /downloads/complete/example_show/example_show.rar

Cannot create Example_show.mkv

Thanks, team linuxserver.io

I have figured it out.

Running OMV5 with the Transmission-Openvpn docker. Issue was that the script would not ruin and this was due to the noexec under the disk where the script is being held. See below how to remove the noexec from the disk/s. Hope this helps others as it took me a while to find the issue and resolve it.

1. SSH your server and become root.

2. (type) nano /etc/openmediavault/config.xml (enter)

3. F6 to search. Search for "noexec" or "mntent"

4. Delete your instances of noexec. You can either delete it on all your disks, or just delete it from the disk that has this script.

5. Cntrl X, Y, then Enter to save.

6. Back at the prompt. For OMV 5: (type) omv-salt deploy run fstab (enter)
   For OMV 4: (type) omv-mkconf fstab (enter)

7. (type) reboot (enter)
