Wie lade ich mit youtube-dl herunter, um den Videotitel als Dateinamen zu erhalten?

Wie wurde die aktuelle Datei heruntergeladen, um den Originaltitel anzuzeigen? Wenn ich immer gerne herunterlade P9pzm5b6Fxx.mp4, wenn der Titel ist Tigerking.

Wie stelle ich es so ein, dass es als heruntergeladen wird tigerking.mp4?

Von man youtube-dl:

-o, --output TEMPLATE
      Output filename template.   Use  %(title)s  to  get  the  title,
      %(uploader)s  for  the  uploader  name,  %(uploader_id)s for the
      uploader  nickname  if  different,  %(autonumber)s  to  get   an
      automatically  incremented  number,  %(ext)s  for  the  filename
      extension, %(format)s for the format  description  (like  "22  -
      1280x720"  or  "HD"),  %(format_id)s  for  the  unique id of the
      format (like YouTube's itags: "137"),  %(upload_date)s  for  the
      upload date (YYYYMMDD), %(extractor)s for the provider (youtube,
      metacafe, etc), %(id)s for  the  video  id,  %(playlist_title)s,
      %(playlist_id)s,   or   %(playlist)s   (=title  if  present,  ID
      otherwise) for the playlist the video is in,  %(playlist_index)s
      for  the position in the playlist.  %(height)s and %(width)s for
      the width and height of the video format.  %(resolution)s for  a
      textual  description  of the resolution of the video format.  %%
      for a literal percent.  Use - to output to stdout.  Can also  be
      used  to  download to a different directory, for example with -o
      '/my/downloads/%(uploader)s /%(title)s-%(id)s.%(ext)s' .

Also vermutlich:

youtube-dl -o '%(title)s.%(ext)s' <URL-of-video>
