As with all DOS and Windows commands issued at the command line,
the correct syntax is obtained by issuing the command with the
switch /?

So for the command shell, you obtain the following:

command /?
Starts a new instance of the MS-DOS command interpreter.

COMMAND [[drive:]path] [device] [/E:nnnnn] [/P] [/C string] [/MSG]

  [drive:]path    Specifies the directory containing COMMAND.COM file.
  device          Specifies the device to use for command input and output.
  /E:nnnnn        Sets the initial environment size to nnnnn bytes.
  /P              Makes the new command interpreter permanent (can't exit).
  /C string       Carries out the command specified by string, and then stops.
  /MSG            Specifies that all error messages be stored in memory. You
                  need to specify /P with this switch.
