Ok so long story short, my raspberry I is no longer connecting to the Internet. I did some research and found that the interfaces file is not in the interfaces.d folder and I'm trying to move it. The I used not the sudo cp and sudo mv commands and they're not recognizing the destination. I've entered it as just "interfaces.d", "/ect/network/interfaces.d", and about a dozen variations of each. I need help.
I agree with joan.
The tutorial How do I set up networking/WiFi/Static IP describes the contents and locations of configuration files (assuming you are using a recent Raspbian - which you haven't specified).
There is ABSOLUTELY NO REASON to fiddle with
If you have done any other damage you may have to start from scratch.
