Sometimes its the little things that annoy us so much on the Unix command line.  One big question for me was… How to do you differentiate between directories and files when recursively chmod-ing?

find . -type f -exec chmod 0644 {} \;

I had some interesting requirements for my Bittorrent needs.  First I wanted to move everything to my linux mediaserver/fileserver.  So I needed a way to work with bittorrent files without traditional access to the machine.  eg. No screen or windowing system.  This led me to TorrentFlux-b4rt, which is a php based web interface to Transmission client meant to be run on apache servers.  Second I wanted to ability to download torrents automatically from RSS sources using scripting.  This is where the original TorrentFlux had failed me and I went searching.

The following is a gathering of scripts I have found and tested.  Most scripts require that you have access to Cron scheduling and the python scripting language.  And, of course, a bittorrent client that scans a directory looking for torrent files.  I am using these scripts in conjunction with rTorrent (a commandline bittorrent client) as well as TorrentFlux-b4rt on various servers.
