------------------------- MS-DOS v6.22 Help: SHELL -------------------------
<Notes> <Examples>                                                   <Index>
----------------------------------------------------------------------------
 
                                   SHELL
 
Specifies the name and location of the command interpreter you want MS-DOS
to use. You can use this command only in your CONFIG.SYS file.
 
If you want to use your own command interpreter (instead of COMMAND.COM),
you can specify its name by adding a SHELL command to your CONFIG.SYS file.
 
Syntax
 
    SHELL=[[drive:]path]filename [parameters]
 
Parameters
 
[[drive:]path]filename
    Specifies the location and name of the command interpreter you want
    MS-DOS to use.
 
parameters
    Specifies any command-line parameters or switches that can be used with
    the specified command interpreter.
 
Related Command
 
For information about COMMAND.COM switches, see the <COMMAND> command.

                                SHELL--Notes
 
Default setting
 
The default command interpreter for MS-DOS is COMMAND.COM. If you do not use
a SHELL command in your CONFIG.SYS file, MS-DOS searches for COMMAND.COM in
the root directory of your startup drive. You need to use the SHELL command
if you want to specify a COMMAND.COM file that is not in the root directory
or if you do not want to use the default environment size for COMMAND.COM.
For information about COMMAND.COM switches, see the <COMMAND> command.
 
Using switches with a command interpreter
 
The SHELL command itself does not accept any switches, but if the command
interpreter does, you can include them on the SHELL command line.
 
                                      ***

<Syntax> <Notes>
----------------------------------------------------------------------------
 
                              SHELL--Examples
 
Suppose the file NEWSHELL.COM is in a directory named BIN on your startup
drive, and suppose you want to use NEWSHELL.COM as your command interpreter.
To do this, add the following command to your CONFIG.SYS file:
 
    shell=\bin\newshell.com
 
Suppose you add the line SHELL=NEWCMDP.COM to your CONFIG.SYS file, and
suppose the NEWCMDP.COM command interpreter accepts the switches /C, /P, and
/E. You can now use any of these switches on the SHELL command line. Thus,
the following command would be valid:
 
    shell=newcmdp.com /c /p /e
 
The SHELL command is the preferred method of using COMMAND to increase the
size of the environment. To increase the environment size to 512 bytes, add
the following command to your CONFIG.SYS file:
 
    shell=command.com /e:512 /p
 
To start an MS-DOS command interpreter located in the directory OLD on drive
C, add the following command to your CONFIG.SYS file:
 
    shell=c:\old\command.com c:\old /e:256 /p
 
For information about COMMAND.COM switches, see the <COMMAND> command.
