BAT File Format

Batch file

BAT is a file extension for a batch file format. BAT files are primarily associated with Microsoft’s Batch Processing.

A batch file takes the form of a text file containing a sequence of commands for an operating system. Batch files are named for the fact that they batch commands into a single file that would otherwise have to be presented to the system interactively from a keyboard one at a time.

The best known batch file is the AUTOEXEC.BAT file, which initializes DOS when you start the system.) In Unix-based operating systems, a batch file is called a shell script.  

Batch processing began in the early days of the mainframe and continues in the mainframe environment to this day.  

MIME type: application/bat, application/x-bat, application/x-msdos-program, application/textedit, application/octet-stream
