@tuicemen Thanks for replying so fast!
Well, it's not just about backup. That was just an example.
I'm talking on Amazon Echo 4th, not Raspberry Pi.
I just want to receive feedback off of what I'm running, the exit code or some echo command.
For example, if I'm doing it without alexa, say running a simple script of echo "hello", I want to know if that was successful or make alexa say "X was done successfuly" or not if it didn't, know what I mean?
