同时运行多个Python脚本，然后依次运行 [英] Running multiple Python scripts simultaneously and then sequentially

问题描述

我可以从bash脚本中同时运行多个Python脚本；

I can run multiple Python scripts simultaneously from a bash script like this;

#!/bin/bash
python pr1.py & 
python pr2.py &
python aop.py &
python loader.py &

但是，如果我希望一批同时启动，并且在它们运行后又要依次启动，该怎么办?这行得通吗?:

But what if I want a batch to fire simultaneously and after they've run, start some more sequentially. Will this work?:

#!/bin/bash
python pr1.py & 
python pr2.py &
python ap.py &
python loader.py
python cain.py
python able.py

推荐答案

在bash脚本上，您可以像这样简单地添加 wait 命令:

On your bash script you can simply add the wait command like this:

#!/bin/bash
python pr1.py & 
python pr2.py &
python ap.py &
wait
python loader.py
python cain.py
python able.py

显然，

wait 将等待所有作业(您触发的后台过程)完成才能继续.

wait will, obviously, wait for all the jobs (the background proccess you fired) to be finished for it to continue.
