box-sizing: border-box; text-size-adjust: none; overflow-wrap: break-word; word-break: break-all; color: #4D4D4D;">.EXE）解释运行。类似于Unix中的Shell脚本。批处理文件具有.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等中高级语言一样。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。</span></p><p style="font-family: -apple-system, "white-space:normal;background-color:#FFFFFF;line-height:24px !important;";
