如何在 Powershell 中启动一个比其父进程还长的后台作业? [英] How can I start a background job in Powershell that outlives it's parent?

问题描述

考虑以下代码:

start-job -scriptblock { sleep 10; cmd /c set > c:\env.txt; }
exit

当父进程退出时后台作业被终止，因此对 cmd.exe 的调用永远不会发生.我想写一些类似的代码，让父进程立即退出，子进程继续在后台运行.

The background job is killed when the parent exits, so the call to cmd.exe never occurs. I would like to write some similar code, such that the parent exits immediately, and the child continues to run in the background.

如果可能，我想将所有内容都保存在一个脚本中.

I would like to keep everything in one script if possible.

推荐答案

您必须启动一个流程:

start-process powershell -ArgumentList "sleep 10; cmd /c set > c:\env.txt" -WindowStyle hidden
