我如何从命令行知道 macOS 有英特尔芯片（或）m1 芯片？

Question

I need to run an executable based on the processor it has. If it has intel based chip then I will run one kind of executable and for an arm-based m1 chip, I will run another executable intended for the same operation.

In order to do the above task, in my code, I need to get the information on which processor was installed in the mac PC from the command line? Could anyone suggest how to get the processor information from the command line for macOS?

It would be great if you answer for other operating systems such as Linux and Windows?
