batch-file - 等待并行批处理脚本

Question

我有 4 个批处理文件。我想同时运行 one.bat 和 two.bat。完成这两个批处理文件后，two.bat 和 four.bat 应立即并行运行。我尝试了很多方法，但效果都很好。

谁能帮我解决这个问题吗？

使用我为Parallel execution of shell processes提供的解决方案的简化版本可以轻松完成此操作。 。请参阅该解决方案以了解文件锁定如何工作的说明。

@echo off
setlocal
set "lock=%temp%\wait%random%.lock"

:: Launch one and two asynchronously, with stream 9 redirected to a lock file.
:: The lock file will remain locked until the script ends.
start "" cmd /c 9>"%lock%1" one.bat
start "" cmd /c 9>"%lock%2" two.bat

:Wait for both scripts to finish (wait until lock files are no longer locked)
1>nul 2>nul ping /n 2 ::1
for %%N in (1 2) do (
  ( rem
  ) 9>"%lock%%%N" || goto :Wait
) 2>nul

::delete the lock files
del "%lock%*"

:: Launch three and four asynchronously
start "" cmd /c three.bat
start "" cmd /c four.bat
