Transmission

I'm not sure where the best place would be to post this question, but I'm working with the following environment:

• Ubuntu Server 10.04
  transmission-daemon version 1.92 as provided by the Ubuntu 10.04 default repositories

My goal is to create a script to run when a torrent is completed to compress all files that torrent downloaded. The reason is simply because this is a remote server, and I want to be able to conveniently grab all of the files from the torrent by downloading one compressed archive. My questions are:

1. Is the script action for completed torrents implemented in this version, or do I need to upgrade?
   Is there an environment variable for the actual files the torrent downloaded to the download directory? I didn't see one, and I could see how that would be difficult for Transmission to determine...
   Assuming that Transmission doesn't have a built-in mechanism capable of executing this, does anyone have any ideas or an existing implementation of this facility?

A simple point in the right direction would be most helpful. I've been playing with a few cron scripting ideas, but the tricky part is knowing when it should execute and making sure it doesn't treat the same downloads multiple times. So far, I had the idea of spawning text files when a torrent is complete to notify the cron script, but I can't figure a way to link those text files to the right downloaded files unless someone has an answer to my second question above.

I'd be grateful for any input. Thanks!

you would need Transmission version 2.00 or higher to run a script on download completion.
something like above would give you a "torrent-name.tar.gz" file in your download directory. this is only a basic outline .. if you do it test on some small torrents first.
