## For updating kodi, but this can be done already from amc script in filebot.
## Besides that, updating library this way does not work if the library is a shared mysql database.
## Leaving this here anyway in case i need it:
# /usr/bin/wget --header='Content-Type:application/json' --post-data='{"jsonrpc": "2.0", "method": "VideoLibrary.Scan", "id": "osmc", "params": {"directory":"'"$TR_TORRENT_DIR"'/"}}' "http://localhost:8080/jsonrpc"

transmission-complete.sh

#!/bin/sh

# Wrapper for stuff i want to run after torrent completion, and because
# transmission is a PITA when dealing with scripts other than shell.
# I can't get environemntal variables directly from my python script so
# this wrapper acts as a proxy since, for some reason, the variables are
# working only in shell scripts so they are then passed on to the child
# processes. Have not tried /bin/sh -c "/PATH/TO/SCRIPT.py" though, maybe
# that works. Who knows. Oh well.
