When writing scripts always use param names and avoid using aliases for code readability and maintainability. get-alias gsv. To explore a command say ps -c dc you can start by issuing get-alias ps to find out what command it is, then get help for the command get-help get-process -Detail. Also it can figure out that -c is parameter computer-name because no other available param starts with a c.
