It makes its results available in the form of files or (via Insert/Update/Delete) in databases or via other output devices (e.g. error situations with the need for operator interventions. The program runs completely independently after startup and usually without any user interaction Exceptions could be e.g. In commercial data processing, batch processing means the automatic, sequential and complete processing of the data contained in one or more input file(s). Overall, the term script is also being used more and more for batch programs.
The current system macOS is also a Unix variant and also knows batch files in the usual sense. On Apple’s Macintosh, these programs are called AppleScript.

These are much more powerful than the first DOS batch programs (up to Windows 9x) since more operating system commands or tools are available on Unix. In Unix, batch files are called shell scripts. On Windows, they can be started by double-clicking. With DOS/Windows, the batch files are usually provided with the file name extension or file name extension. Batch files contain a set of commands that take advantage of the operating system features these are processed step by step by executing the batch file. In this context, the term batch file or the batch file has become known, especially through MS-DOS. The term batch processing is often used to process operating system-related services and tasks. The term ‘batch processing’ has two different meanings: In this form of processing, the work results are also usually available as ‘quantity’, for example as documents, lists (reports), new or changed data sets, etc. magnetic tapes and disk drives, and interactive work with the dialogue computer became possible (with direct input via a terminal), the term was preserved and is still used today for non-interactive data processing: you place an order this is processed by the computer with all associated data “without the intervention of the user in sequence”. Later, when the punch card was replaced by other storage media, e.g.

At that time, data sets were often available in the form of punch cards and were processed successively by the respective computer program – whose program code was often also available as a stack of punched cards – as a stack of cards. The term batch processing comes from the early days of data processing when interactive processing was not yet possible. After that, the program ‘waits’ for further transactions any orders that may arrive in parallel must be processed one after the other or separately from each other. The program processes exactly one operation (a transaction), which is usually initiated interactively by a user via a computer workstation for processing. The complementary form of processing is called “dialogue processing”. Batch processing is a term used in data processing and refers to the way computer programs work in which the amount of tasks or data provided as input in one or more data sets is processed completely, automatically and usually sequentially.
