title: youtube-dl How to get subtitles filename?
body: <p>With youtube-dl, you can get the video filename (--get-filename) and you can get the list of available subtitles (--list-subs), but it doesn't seem to have anyway to retreive the file name of the downloaded subtitles.</p>
  
  <p>If I want to only download the subtitles of a video, I'd do something like this :</p>
  
  <p><code>youtube-dl.exe --write-sub --sub-format best --sub-lang en --skip-download -o "~/Videos/%%(title)s.%%(ext)s" YOUTUBE_URL</code></p>
  
  <p>Then, the subtitle would download as 
     TITLE-en.EXTENSION</p>
  
  <p>But if I do something like this</p>
  
  <p><code>youtube-dl.exe --write-sub --sub-format best --sub-lang en --skip-download -o "~/Videos/%%(title)s.%%(ext)s" YOUTUBE_URL --get-filename</code></p>
  
  <p>It only gives me the filename of the video.</p>
  
  <p>Any help ?</p>
