Accessing torrent file list in the on-completion script

[Tepelstreeltje]

I'm trying to write a simple script to scan (clamav) all files that were downloaded up on completion.
For most torrents having the torrent name and download directory is enough, however if the torrent name is not the same as the file or the directory of the content, I am forced to scan the entire downloads folder just to make sure everything was scanned.

So I'm wondering if there is an easy way to get access to a file list for the just completed torrent.
The only way i can see it working at the moment is generating a file list for every active torrent every X minutes and then using those file lists in the on-completion-script,
however I don't like that approach much, if needed i will implement it this way, but I would prefer having direct access to a filename-array of some sort directly in the on-completion script.
Is such an array available? Is it possible to implement it ?

The only variables that I have found any mention of on the web are :

TR_TORRENT_DIR
TR_TORRENT_NAME
TR_TORRENT_ID
TR_TORRENT_HASH
TR_TIME_LOCALTIME
TR_APP_VERSION

As soon as I have done a bit more polishing I will post the script here so others can use it too.

Something like :

Code: Select all

#!/bin/sh
{
# Go to the download directory (the file list is relative to that point)
cd \"$TR_TORRENT_DIR\"

# Get a list of files (it will include directory/file or similar to any depth)
transmission-remote -t $TR_TORRENT_ID --info-files  |
tail -n +3 | cut -c 35- | 

# Process the list
while read f
do
  clamdscan \"$f\"
done
} &

Which means all the information is there, be careful using transmission-remote or your script will block, since scanning can take a long time everything is run in the background.

Cheers, kinda stupid of me to forget I could use the torrent id to access the specific filelist !
I'll try to post the entire script after work tonight
