A batch file is a kind of script file in DOS, OS/2 and Windows. A sequence of commands for a computer operating system that store in a text file is known as batch file. Its called a batch file because it batches (bundles or packages) into a single file. A batch file is usually created for command sequences for which a user has a repeated need. Commonly needed batch files are often delivered as part of an operating system. You initiate the sequence of commands in the batch file by simply entering the name of the batch file on a command line.
A batch file has the file name extension "BAT". In UNIX-based operating systems, a batch file is called a shell script. In IBMs mainframe VM operating systems, its called an EXEC.
