The Exit-PSHostProcess cmdlet closes an interactive session with a local process that you have opened by running the Enter-PSHostProcess cmdlet. You run the Exit-PSHostProcess cmdlet from within the process, when you are finished debugging or troubleshooting a script that is running within a process.
Example 1: Exit a process
[Process:1520]: PS> Exit-PSHostProcess PS>
In this example, you have been working in an active process to debug a script running in a runspace in the process, as described in Enter-PSHostProcess. After you type the exit command to exit the debugger, run the Exit-PSHostProcess cmdlet to close your interactive session with the process. The cmdlet closes your session in the process, and returns you to the PS C:\> prompt.
