history  [<N>]                                         Default: 10

     The history command displays the number and contents of previous
     commands retained in a circular list, or sets the depth <N> of the
     history list.  These commands can be recalled by the UP-arrow and
     DOWN-arrow keys.  Press return to execute a recalled command, or
     backspace to erase from the right side.  No further editing is
     currently supported.  Setting the list size to 0 (zero) disables
     this feature.
