A batch file is a text file that includes the lines of Microsoft DOS commands. DOS batch files have the .bat file name extension. Batch files are useful to automatically execute programs in a sequence and to automate the computer tasks that require multiple or repetitive steps. You can use the ECHO command in a batch file to see text messages on the computer screen. By displaying text messages included with the .bat file, you can monitor its execution.
