How to generate a new module using angular CLI?

Like component and services, we can create module in the same way. Below are the commands

ng g m students -d -m=app.module

ng g m students -d -m=app.module --spec=true

ng g m students -d -m=app.module --spec=true --flat=true

ng g m students -m=app.module --spec=true --flat=true
