How to set highest quality when downloading?

[humanfriend22]

Videos have differing qualities, so I would like to download them at the highest quality available. How is this possible?

  # check required params and arguments
  [[ ${#args[@]} -eq 0 ]] && die "Missing script arguments"

  echo "[]" > /tmp/youtube.json
