add .mkv to sonarr comples but not imported

sonarrMKV.py

#!/usr/bin/python3
import os
import pathlib

####
# What is this for?
# For some reason, Sonarr does not support automatic NOR manual importing
# of files if the filenames are obfuscated and contain no file extension.
# IMO, if the episode directory can be parsed correctly, and there is only
# one file (without an obvious file type extension) in the directory, we can confidently
# assume that to be the target episode video file.
# All this script does it rename that file with ".mkv" appended to the filename,
# which should trigger automatic importing/completion in sonarr.
####

####
# Make sure you `cd` into your downloads folder where the Show folders are.
# e.g., /downloads/Series
# make sure this python file is in the directory and executable
# run it: ./sonarrMKV.py
# or as long as it's readable: `python3 sonarrMKV.py`
