deleting m4a after merging youtube-dl

Question

I am trying to download a playlist from youtube but I always have this problem:

youtube-dl download video, sound and merge.

But when it tries to delete the rest, there is no progress.

Answer 1

This is a shell problem not a youtube-dl issue, since the url contains a & character you have to quote the url:

youtube-dl 'https://www.youtube.com/watch?v=cKlJrMyWAE0&list=PLBD47CE9F15D97BEC'

otherwise youtube-dl only gets https://www.youtube.com/watch?v=cKlJrMyWAE0(you can check this by running youtube-dl with the --verbose option). There is more info in the youtube-dl README.
