title: Remove Android SDK packages from command line
body: <p>is there a way to remove selected package (e.g. "Samples" for each API level) from command line?
  I'm using Linux.
  I'm aware of the answer <a href="https://stackoverflow.com/questions/19775404/uninstalling-selected-parts-of-android-sdk-on-the-command-line">Uninstalling selected parts of Android SDK on the command line</a> but it doesn't quite cover all the topic.</p>
  
  <p>Or is it safe to delete the folders without using any android tool?</p>
