macOS How do I find my Macs model from terminal?

[glossywhite]

Hi. what command do I issue to Terminal.app, to get my Mac model; for example "Macmini3,1". It HAS to be Terminal, thanks.

[EDIT]

FOUND IT!!:

sysctl hw.model

 

[Guiyon]

try:

/usr/sbin/system_profiler SPHardwareDataType

The information you want will be next to the "Model Identifier" key

 

[angelwatt]

Try this out,

system_profiler | grep "Model Id"

 

[Peace]

Why use the terminal when it's right there in the system profile ?

... because I am trying to find out if this PERL script is checking model ID of Macs, when installing Snow Leopard. Can someone shed some light on what this script does?:

#!/usr/bin/perl
