For use with transmission-daemon, enable script-torrent-done-enabled and set this script as script-torrent-done-filename. It will scan your TV folders and try to move the completed torrent into the correct one, by turning both the folder name and torrent name to lower case, stripping out all non alpha characters, and looking for the folder name …

torrent_complete.sh

#!/bin/bash

for i in /home/jwh/Downloads/HTPC/TV/*
do
    # Look for the TV folder names inside the torrent name
    SHOWDIR=`basename "$i" | tr '[A-Z]' '[a-z]' | tr -cd [:alpha:]`
    SHOW=`echo ${TR_TORRENT_NAME} | tr '[A-Z]' '[a-z]' | tr -cd [:alpha:]`

    if [[ ${SHOW} =~ ${SHOWDIR} ]]
    then
        # Move, stop and remove the torrent
        CMD="mv $TR_TORRENT_DIR/\"$TR_TORRENT_NAME\" \"$i\""
        eval $CMD
        transmission-remote localhost:9091 --auth=bt:bt -t ${TR_TORRENT_ID} -r
