title: How to view unallocated free space on a hard disk through terminal
body: <p>I want to view the unallocated free space on my hard disk through terminal.
  I've burned my brains searching the internet for a possible solution, but all in vain.</p>
  
  <p>I used all sorts of commands like <code>df</code>, <code>du</code>, <code>fdisk</code>, <code>parted</code>, etc.
  It tells me about the disks that are mounted and unmounted, but what about the unallocated space that I've left free?</p>
  
  <p>Of course I can view it using the 'Disk Utility' app provided by Fedora, but since I LOVE being in the terminal I'd like to view in it.</p>
  
  <p>Can anyone please help me with a solution?</p>
