Creating a batch file
Running a batch file
Suppose, for example, that you want to create a batch file to
format and check a new disk. To do this you simply follow
these steps:
E First, type the following:
copy con checknew.bat
Press return. This command tells ms-dos to copy the informa
tion from the console (keyboard) to the file checknew.bat.
[H Next, type the following lines, pressing return after each:
rem This is a file to format and
rem check new disks.
rem It is named CHECKNEW.BAT.
pause Insert new disk in drive B:
format b: /v
chkdsk b:
H] After the last line, press control-z and then press return to
save the batch file, ms-dos displays the message "1 File(s)
copied" to show that it created the file.
H Now, to execute the file, simply type the following command:
chec knew
U
U
u
o
u
The result is the same as if the lines in the .bat file were entered
from the keyboard as individual commands.
About Batch Processing
Here are a few things you should know before you run a batch
process with ms-dos:
■ You must name each batch file with an extension of .bat.
■ To execute a batch file, you type only its filename and not the
extension.
■ If you press control-c while the batch file is running, ms-dos
asks you to confirm that you want to terminate the batch
process.
■ If you remove the disk that contains a batch file being run, ms-
dos prompts you to reinsert the disk so that it can continue
processing the file.
■ You can specify the name of another batch file as the last com
mand in a batch file. This feature allows you to call one batch
file from another when the first has finished.
