A batch file is a special kind of computer file that tells a computer a list of instructions to do in order. Batch files were used a lot when DOS was used by many people. They are good for automating many small pieces of work. Some people still use batch files today.
Hello World example[change | change source]
This is an example of a batch file. It is called a "Hello World" example because it prints the text "Hello World!" to the screen.
@ECHO off
ECHO Hello World!
PAUSE
When that text is put into a file with an extension of .bat, saved, and run, it will put this on the screen:
Hello World! Press any key to continue . . .
