Batch programs (also called batch files) allow you to simplify routine or repetitive tasks. A batch program is an unformatted text file that contains one or more commands and has a .BAT or .CMD filename extension. When the filename is typed at the command prompt, the commands in the file are run sequentially.
Any command can be included in a batch file. In addition, several commands allow conditional processing of the commands in the batch file. For example, the if command carries out a command based on the results of a condition. Other commands allow you to control input and output and to call other batch programs. You can use the following commands in batch programs.
