阅读更多关于 powershell v2 - how to get process ID

问题 I have an Application, that runs multiple instances of itself. e.g AppName.exe instance1 AppName.exe instance2 AppName.exe instance3 Using Powershell v2 I am trying to create a simple script that given an array of AppNames and instances, it loops through them, checks if they are running, and then shuts them down.

阅读更多关于 Call a BAT in an elevated window and changing ENV variables before
