Yep. It's pretty much that simple. Kind of hard to believe for me actually. And, I think I know what you mean by "no feedback" because I sort of still yearn for the days when command prompt was still in heavy rotation (at least in college) when you'd type a command (some switch) and the system would always provide some decent feedback like, "command executed successfully." https://support.microsoft.com/en-us/kb/3161102
Sorry for nothing more technical. Best of luck.
