I’m just trying to understand what workflow you’re trying to simulate here. What exactly would this apply to in real world usage? I don’t use bash or anything so I don’t know what you’re showing with this thread?
That's like asking why anyone would need to learn how to drive a car when they already ride a bike. If you haven't used MacOS or any other mainstream unix OS with bash shell and don't see the significance of batch processing then this thread isn't for you.
