How to get the Disk Image property using terminal? 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.
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.

Which is basically the same as using the Disk Utility application.
