在 powershell 退出时运行脚本

Question

我将如何运行可在exit命令或 shell 关闭上运行的 powershell 脚本。我希望这个脚本在每个关闭的 shell 上运行，而不仅仅是一个 shell。

脚本

Answer 1

使用Register-EngineEvent您可以这样做：

Register-EngineEvent PowerShell.Exiting –Action { 'Type your Code' }

# Alternatively with hiding the event: 
Register-EngineEvent PowerShell.Exiting –Action -SupportEvent { yourExitFunction; }

Answer 2

将其从函数中取出并在脚本块中运行它，如下所示：
