title: Getting Primary HDD serial on OSx using terminal
body: <p>Ok, so I think the title of this question pretty much sums it up.</p>
  
  <p>I would to know of a way to obtain the serial number of the HDD  that the operating system is installed on, in OSx without having Admin privileges. Preferably, I would like to do this using Terminal because I need to use the serial in my Java application and I doubt Java has the capabilities to obtain the information itself.</p>
  
  <p>Thanks in advance</p>
