I've been searching here and across the web for a bash script that leverages the YouTube API to update the Title, Description, Playlist, Category and Thumbnail given a YouTube livestream video ID. My preference is to do this using bash/curl to keep it simple, but I've been unable to make any progress.
I've seen this question asked a few times, but the feedback given over the last couple years has been a redirect to the YouTube API documentation which I've gone through thoroughly, but have been unsuccessful in achieving the outcome described above.
Looking forward to any help you can provide.
