title: How can I work with command line on synology?
body: <p>How do I access the command line interface on a Synology NAS.</p>
  <p>Specifically, I am trying to access the command line on a Synology DS1520+, running DSM 7.1, so I can enter the command:
  <code>sudo shutdown -h</code>,
  so I can power down the NAS remotely.</p>
  <p>I am pretty sure I should use SSH and unix/linux style commands.</p>
