Start a specified program or command in a separate window.
Syntax
START " title " [/D path ] [ options ] " command " [ parameters ]
Key:
title : Text for the CMD window title bar (required)
path : Starting directory
command : The command, batch file or executable program to run
parameters : The parameters passed to the command
Options:
/MIN : Minimized
/MAX : Maximized
/WAIT : Start application and wait for it to terminate
/LOW : Use IDLE priority class
/NORMAL : Use NORMAL priority class
/HIGH : Use HIGH priority class
/REALTIME : Use REALTIME priority class
/B : Start application without creating a new window. In this case
^C will be ignored - leaving ^Break as the only way to
interrupt the application
/I : Ignore any changes to the current environment.
Options for 16-bit WINDOWS programs only
/SEPARATE Start in separate memory space (more robust)
/SHARED Start in shared memory space (default)
Notes:
Always include a TITLE this can be a simple string like "My Script" or just a pair of empty quotes ""
According to the Microsoft documentation, the title is optional, but you may have problems if it is omitted.
Document files may be invoked through their file association just by typingthe name of the file as a command.
e.g. START "" WORD.DOC would launch the application associated with the .DOC fileextension
Examples
START "My Login Script" /Min Login.cmd
START "" /wait MySlowProgram.exe
Printers
A new printer can be installed very quickly (and the driver downloaded)with the command:
START \\print_server\printer_name
Setting a Working Directory
To start an application and specify where files will be saved:
START /Dc:\Documents\ /MAX "Maximised Notes" notepad.exe
Forcing a Sequence of Programs
If you require your users to run a sequence of 32 bit GUI programs to completea task, create a batch file that uses the start command:
@echo off
start /wait /b First.exe
start /wait /b Second.exe
start /wait /b Third.exe
Create a shortcut to this batch file and place it on the Start menu or desktop.Set it to run minimized.
When the user double-clicks the shortcut, <First.exe> runs.
When <First.exe> terminates, <Second.exe> runs
When <Second.exe> terminates, <Third.exe> runs
An alternative method is to run a .BAT batch file under command.com (16 bit)
If Command Extensions are disabled, the START command will no longer recognise file Associations, and will not automatically evaluatethe COMSPEC variable when starting a second CMD session.
Missing file extensions
When executing a command line whose first token does NOT contain anextension, then CMD.EXE uses the value of the PATHEXT environmentvariable to determinewhich extensions to look for and in what order. The default value forthe PATHEXT variable is:
.COM;.EXE;.BAT;.CMD
Notice the syntax is the same as the PATH variable, with semicolons separating the different elements.
When executing a command, if there is no match on any extension, thenWindows will look to see if the name, without any extension, matches adirectory name andif it does, the START command will launch Explorer on that path.
