# what is this? query your Radarr library and make changes via the API.
# in this example we query all Radarr entries, identify movies that are named (movie title), THE (year) and update the .path and .folderName to (THE movie title) (year)
# after updating Radarr, rename the folders on the filesystem; https://gist.github.com/scrathe/0bedf625916df1a0d070c053c284017d
