script must display an error message if arguments are invalid, and then terminate.

2) Clear the screen before you begin processing the command.

3) If the destination directory exists, prompt the user to verify that this is destination is
acceptable. For example:
▪ if user responds y then continue processing
▪ if user responds n then terminate the script.
▪ else, prompt again.
