Transmission post-download script: Sort Torrents in folders by tracker

trkrsort.sh

#! /bin/bash
#Requires transmission-remote in $PATH.
#Make sure you are allowing the RPC and are not being limited by the whitelist
#First see how can you log in to transmission and then adjust these values
#Try running `transmission-remote` first and see what happens
	TR_USERNAME="username"
	TR_PASSWORD="password"
	# might be able to leave empty, test it out. I'm running mine through an nginx reverse proxy.
	TR_HOST="https://localhost/transmission/rpc"

TRACKER=$(transmission-remote $TR_HOST -n "$TR_USERNAME":"$TR_PASSWORD" -t$TR_TORRENT_ID -it | sed -n -e '/[:]/p' | head -1 | awk '{print substr($0, index($0,$3))}' | awk -F[/:] '{print $4}')

dir="${TR_TORRENT_DIR}/${TRACKER}"
if [[ ! -d "$dir" ]]; then
	mkdir -p "$dir"
fi

transmission-remote $TR_HOST -n "$TR_USERNAME":"$TR_PASSWORD" -t$TR_TORRENT_ID --move "$dir"

This script will create folders in your default torrent directory based off what the domain of the first tracker is.
For example, if you download The ubuntu 20.04 server torrent, it will make a folder called torrent.ubuntu.com and move the torrent data there.
