DOS / batch refrence

@ Does not echo back the text after the at symbol. This is most commonly used as @ECHO OFF to prevent any of the commands in the batch file from being displayed, just the information needed.


%1 The percent followed by a numeric value, beginning with one, allows users to add variables within a batch file. The below line is an example of what can be used in a batch file.

ECHO Hello %1

When the above one-line batch file is created, add your name after the batch file. For example, typing myname (being the name of the bat file) and then your name:

myname bob

would output:

Hello bob

Note: This can be extended to %2, %3, and so on.




:LABEL By adding a colon in front of a word, such as LABEL, you create a category, more commonly known as a label. This allows you to skip to certain sections of a batch file such as the end of the batch file. Also see GOTO.



CALL This is used to run another batch file within a batch file. When the batch file that is called is completed, the remainder of the original batch file is completed. Note if the batch file does not exist it will give an error message.


CHOICE See running different programs for an example of how to use this command.


CLS Just like the DOS command would clear your screen.



ECHO Will echo a message in the batch file. Such as ECHO Hello World will print Hello World on the screen when executed. However, without @ECHO OFF at the beginning of the batch file you'll also get "ECHO Hello World" and "Hello World." Finally, if you'd just like to create a blank line, type ECHO. adding the period at the end creates an empty line.



EXIT Exits out of the DOS window if the batch file is running from Windows.


GOTO LABEL Used to go to a certain label, such as LABEL. An example of GOTO would be to GOTO END. For an example of this see running different programs.


IF Used to check for a certain condition if the condition exists. If that condition exists it will perform that function. To see an example of this see running different programs.


PAUSE Prompt the user to press any key to continue.



REM Allows you to place remarks into the batch file without displaying or executing that line when the batch file is run.



SHIFT Changes the position of replaceable parameters in a batch program.



START Used for Windows 95, Windows 98, and Windows NT 4.0 and above to start a windows application; such as START C:\WINDOW\CALC would run the Windows Calculator. Users running Windows 3.x need to utilize the WIN command. For example, WIN C:\Windows\CALC.EXE would run Windows and then Calculator after Windows has finished loading.
