如何等待所有批处理文件在退出前完成？

问题描述

我比调用的主批处理文件4其他批处理文件，所以我们可以并行运行。

I have a main batch file than calls 4 other batch files so we can run in parallel.

例如：

Main.bat

    start call batch1.bat
    start call batch2.bat
    start call batch3.bat
    start call batch4.bat

    exit

我希望所有的BATCH1批4已经停止执行后，Main.bat退出。通过这种方式，我可以得到批处理文件的总运行时间。问题是Main.bat退出BATCH1到batch4执行完毕之前也。

I want the Main.bat to exit after all the batch1 to batch 4 has stopped executing. In this way, I can get the total run time of the batch file. Problem is Main.bat exits even before batch1 to batch4 finishes executing.

我试图来计算％ERRORLEVEL％每批文件，但它始终返回0，即使4 .bat文件仍在运行。

I tried to compute for %errorlevel% for each batch file, but it always return 0 even though the 4 .bat files are still running.

希望有人能帮帮我！

感谢您！ ：）

推荐答案

我觉得这是最简单，最有效的方式：

I think this is the simplest and most efficient way:

@echo off

echo %time%

(
    start call batch1.bat
    start call batch2.bat
    start call batch3.bat
    start call batch4.bat
) | set /P "="

echo %time%

在此方法中的主要文件中的等待状态的事件驱动的，所以它不占用任何CPU！

In this method the waiting state in the main file is event driven, so it does not consume any cpu!
