How to view unallocated free space on a hard disk through terminal

linux terminal fedora hard-drive

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.

I used all sorts of commands like df, du, fdisk, parted, etc. It tells me about the disks that are mounted and unmounted, but what about the unallocated space that I've left free?

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.

Can anyone please help me with a solution?

GNU Parted 2.3
