Command Ü
ßßßßßßßß
Starts another instance of the command interpreter.
A command interpreter is a program that lets you type commands. Use the
EXIT command to stop the new command interpreter and return control to
the old one.
Syntax: COMMAND [[drive:]path] [device] [/E:nnnnn] [/Y [/C command|
/K command]]
In your CONFIG.SYS file, use the following syntax:
SHELL=[[dos-drive:]dos-path]COMMAND.COM [[drive:]path][device]
[/E:nnnnn] [/P [/MSG]]
drive:path
Specifies the directory in which the command interpeter is to look
for the COMMAND.COM file when the transient part of the program
needs to be reloaded. This parameter must be included when loading
COMMAND.COM for the first time if the COMMAND.COM file is not located
in the root directory. This parameter is used to set the COMPSPEC
environment variable.
device
Specifies a different device for command input and output.
DOS-drive:DOS-path
Specifies the location of the COMMAND.COM file.
/C command
Specifies that the command interpreter is to perform the specified
command and then exit. This switch must be the last switch on the
command line.
/E:nnnnn
Specifies the environment size, where nnnnn is the size in bytes.
The value of nnnnn must be in the range of 160 to 32768. FreeDOS
rounds this number up to a multiple of 16 bytes. The default value
is 256.
/K command
Runs the specified command, program, or batch program and then
displays the FreeDOS command prompt. This switch must be the last
switch on the COMMAND command line.
/P
Should be used only when COMMAND is used with the SHELL command in
the CONFIG.SYS file. The /P switch makes the new copy of the
command interpreter permanent. In this case, the EXIT command
cannot be used to stop the command interpreter. If you specify
/P, FreeDOS runs your AUTOEXEC.BAT file before displaying the
command prompt. If there is no AUTOEXEC.BAT file in the root
directory of the startup drive, FreeDOS carries out the DATE and
TIME commands instead. If you do not have a SHELL command in your
CONFIG.SYS file, COMMAND.COM is automatically loaded from the root
directory with the /P switch.
/MSG
Specifies that all error messages should be stored in memory.
Usually, some messages are stored only on disk. This switch is
useful only if you are running FreeDOS from floppy disks. You must
specify the /P switch when you use the /MSG switch.
/Y
Directs COMMAND.COM to step through the batch file specified by
the /C or /K switches. This switch is useful for debugging batch
files.
