Setup

1. Download this file from YouTube and place it in the folder with the script with the name .subscription_manager.
2. Run ./.yt-subscriptions.sh. It will use youtube-dl to automatically download all videos since the last time it was run (or 24h if it has not been run before).
3. Run ./.start.sh to automatically play each video, and prompt for deletion after playing.

I recommend setting a keybind to run .start.sh in a terminal. You can also use crontab to have .yt-subscriptions.sh automatically download videos in the background.
