A batch file is a text file containing a series of commands that are executed by the command interpreter on MS-DOS, IBM OS/2, or Microsoft Windows systems.
Batch files are text-based scripts, usually saved with the .bat, .cmd, or .btm filename extension. They are executed by the command processor (typically COMMAND.COM on MS-DOS and earlier versions of Windows, cmd.exe on IBM OS/2 and later version of Windows). Note that, while batch files are still supported under Windows, recent versions have the much more expressive Powershell.
Example
This is the source code to a typical "Hello world" program in batch programming:
@ECHO off
ECHO Hello World!
PAUSE
Note the ! may not display if delayed expansion is enabled.
Tag usage
The tag batch-file can be used for programming-related problems in writing a batch script file for a Windows-based operating system. Please avoid "suggest a book"-type questions. Note the batch-file tag is not to be used for questions referring to a "batch of files" but for questions related to the shell language only.
