并行启动多个任务，然后在Windows中等待它们? [英] Start multiple tasks in parallel and wait for them in windows?

问题描述

如何在批处理脚本中并行执行一些任务并等待它们?

How do I execute some tasks in parallel in batch script and wait for them?

command1;

# command3, command4 and command5 should execute in sequence say task1
# command6, command7 and command8 should execute in sequence say task2
# both task1 and task2 should run independently

command3; command4; command5 | command6; command7; command8;

# should execute only after the above parallel tasks are completed

command9;

作为概念验证，我尝试了类似的方法，但是它不起作用:

As a proof of concept I tried something like but it is not working:

echo "Starting"
start /wait wait20.bat   
start /wait wait40.bat 
echo "Finishing"

wait20.bat看起来像:

echo "starting 20 seconds job"
timeout 20
echo "finishing 20 seconds job"

我在做什么错了?

推荐答案

我认为这是最简单的方法

command1

(
   start "task1" cmd /C "command3 & command4 & command5"
   start "task2" cmd /C "command6 & command7 & command8"
) | pause

command9
