How to create m3u playlists per directory using the CLI, terminal, on Ubuntu

[scooke]

Hello! I hope everyone is well.

I run a jellyfin instance, and upload folders of music, many of which don't have a playlist file, .m3u. I've come across posts (not many) which suggest I can use Strawberry to create playlists... but they don't say how.

I've installed Strawberry on my Ubuntu server, and am hoping someone can tell me the proper cli commands to create a playlist for a folder full of music files (mp3, flac, etc, but each folder is just one music file type). Thank you!
