How to get the Disk Image property using terminal?

Question

Let's say I have the volume path. Normally I can right-click and 'Get info' to get its Disk image. I want to replicate the same on terminal (basically need to code it in objective C) mdls doesn't seem to helping. Not xattr, putils etc.

Answer 1

The Disk Utility application shows the following on my Mac.

If I select "Get Info" on Marlin, I get the following popup.

I can also get information about the volume labeled Marlin by entering the following command in a Terminal application window.

diskutil  info  Marlin

Doing so produces the following output.

   Device Identifier:        disk0s4
   Device Node:              /dev/disk0s4
   Whole:                    No
