批处理（Batch）通常被认为是一种简化的脚本语言，它应用于DOS和Windows系统中，它是由DOS或者Windows系统内嵌的解释器（通常是COMMAND.COM或者CMD.EXE）解释运行。类似于Unix中的Shell脚本。批次档具有.bat或者.cmd的扩展名，其最简单的例子，是逐行书写在命令行中会用到的各种命令。更复杂的情况，需要使用if、for、goto等命令控制程序的运行过程，如同C、Basic等高级语言一样。如果需要实现更复杂的应用，利用外部程序是必要的，这包括系统本身提供的外部命令和第三方提供的工具或者软件。批处理进程虽然是在命令行环境中运行，但不仅仅能使用命令行软件，任何当前系统下可运行的进程都可以放在批处理文档中运行。

A batch file is a kind of script file in DOS, OS/2 and Windows. It consists of a series of commands to be executed by the command line interpreter, stored in a plain text file. A batch file may contain any command the interpreter accepts interactively and use constructs that enable conditional branching and looping within the batch file, such as "if", "for", "goto" and labels. The term "batch" is from batch processing, meaning "non-interactive execution", though a batch file may not process a batch of multiple data.
