How to utilize the About this Mac Storage report through Terminal


Anybody know a way to run the System Profiler (System Information) app, which provides the About this Mac/Storage info? The goal would be to combine the results from this dialog box (ie how much Audio, Movies, Photos, etc.) along with a DF command and Search command for how many files of a specific type (ie .psd, .jpg, .mov, .mp3, etc) to supply a report of user's data types and sizes.

I've found two 3rd party utilities, but in any case, I can't find any related terminal commands in order to script and process the results.
Daisy Disk
But I'd prefer the built in System Profiler.

Any guidance would be appreciated.
