Using AUTOEXEC.BAT and Other Batch Files
As you get used to using MS-DOS and your application
programs, you may find that there are commands you need to
run frequently. You can automate the execution of these
commands by listing them in a special file called a “batch” file.
When you type the name of the batch file and press Enter,
MS-DOS executes the commands in the file just as if you had
typed each command from the keyboard.
If you have a word processing program that can save a file as a
text-only file (sometimes called an ASCII file), you can use it to
create a batch file. You can also use the MS-DOS COPY or
EDLIN command to create the file.
One batch file that you may find particularly useful is called
AUTOEXEC.BAT. E
very time you turn on your computer,
MS-DOS looks for the AUTOEXEC.BAT file and
automatically executes each of the commands.
