Command: command.com (or FreeCom)

  COMMAND starts a new copy of the FreeDOS command shell.

Syntax:

  COMMAND [[drive:]path] [device] [/E:nnnnn] [/L:nnnn] [/U:nnn] [/P]
          [/MSG] [/LOW] [/Y [/[C|K] command]]
  COMMAND [/?]
  [drive:]path  The drive and path where the shell is to look for the
                transient part of COMMAND.COM. This is usually only
                needed to set the COMSPEC,
                e.g. C:\FREEDOS\BIN\
  drive         The drive letter, e.g. C:
  path          The directory, e.g. \FREEDOS\BIN\
  device        Specifies the device to use for command input
                and output.

Options:

  /e:nnnnn   The environment size, in bytes, in the range 160-32768.
             This number will be rounded up the nearest 16 bytes.
             The default is 256.
  /L:nnnn    Specifies internal buffers length (requires /P as well).
             (nnnn should be between 128 and 1,024.)
  /U:nnn     Specifies the input buffer length (requires /P as well).
             (nnn should be between 128 and 255.)
  /P         Makes the shell permanent, so the EXIT command does
             not exit the shell.
  /MSG       Stores all error messages in memory (requires /P as well).
  /LOW       Forces the command shell to keep its resident data in
             low memory.
  /Y         Steps through the batch program specified by /C or /K
  /C string  Executes the command in {string}, then exits.
  /K string  Executes the command in {string}and continues running.
  /?         Shows the help

Comments:

  Command (command.com) is also named FreeCom. It contains a lot of
  internal commands which need no other file in order to work. You can
  find the list of internal commands here or by typing "?" in
  command line.
