title: Apple File System (APFS) Check if file is a clone on Terminal (shell)
body: <p>With macOS High Sierra a new file system is available: APFS.</p>
  
  <p>This file system supports clone operations for files: No data duplication on storage.</p>
  
  <p><code>cp</code> command has a flag (-c) that enables cloning in Terminal (shell).</p>
  
  <p>But I didn't find a way to identify theses cloned files after.</p>
  
  <p>Somebody knows how to identify cloned files with a shell command, or a flag in a existent command, like <code>ls</code>?</p>
