Key
   CommonParameters:
       -Verbose, -Debug, -ErrorAction, -ErrorVariable, -WarningAction, -WarningVariable,
       -OutBuffer -OutVariable.

To end the interactive session and disconnect from the remote computer, use Exit-PSSession, or type "exit".

Examples

Start and then stop an interactive session with the Server64 remote computer:

PS C:> Enter-PSSession -computername Server64
Server01\PS> Exit-PSSession

Start and stop an interactive session with Server64, the status of the PSSession shows that the session is still available when the interactive session ends.:

PS C:> $sess = new-pssession -computername Server64
C:\PS> Enter-PSSession -session $sess
Server01\PS> Exit-PSSession
C:\PS> $sess
    
    Id Name            ComputerName    State    ConfigurationName
    -- ----            ------------    -----    -----------------
    1  Session1        Server64        Opened   Microsoft.PowerShell

Note that if Enter-PSSession -ComputerName is used (instead of new-psSession), then Enter-PSSession would have automatically created a temporary session that would close as soon as the interactive session ends.

Start PowerShell.exe and run a .ps1 script that will exit returning an ErrorLevel back to the calling shell (in this case CMD.exe)

C:\> Powershell.exe -noprofile –file "C:\bats\DemoScript.ps1"
:: DemoScript.ps1ends with the line: Exit-PSSession 64
C:\> Echo %ERRORLEVEL%
64
