        SYNOPSIS:
            history [<COUNT>]

        DESCRIPTION:
            Returns a formatted string giving the event number and
            contents for each of the events in the history list
            except for current event.

            If [COUNT] is specified, only the [COUNT] most recent
            events are displayed.

            > history
              - Display the full history of events.
            > history 10
              - Display last 10 commands of the history.
