How to close every interactive PowerShell session?

Question

Is there a way to exit every interactive PowerShell session created by Enter-PSSession in PowerShell?

I tried something like :

Get-PSSession -ComputerName $computerName -Credential $credential | Exit-PSSession

or

Get-PSSession -ComputerName "pp1KYCiis01" -Credential eperret@vppp.local | foreach { Exit-PSSession $_ }

But does not seem to be right...

Exit-PSSession : The input object cannot be bound to any parameters for the command either because the command does not take
pipeline input or the input and its properties do not match any of the parameters that take pipeline input.
[...]

Example of Get-PSSession :

PS C:\Users\eperret> Get-PSSession -ComputerName $computerName -Credential $credential

 Id Name            ComputerName    ComputerType    State         ConfigurationName     Availability
 -- ----            ------------    ------------    -----         -----------------     ------------
 36 WinRM7          computerNam     RemoteMachine   Disconnected  Microsoft.PowerShell          Busy
 37 WinRM4          computerNam     RemoteMachine   Disconnected  Microsoft.PowerShell          Busy
 38 WinRM2          computerNam     RemoteMachine   Disconnected  Microsoft.PowerShell          Busy
 39 WinRM5          computerNam     RemoteMachine   Disconnected  Microsoft.PowerShell          Busy
 40 WinRM3          computerNam     RemoteMachine   Disconnected  Microsoft.PowerShell          Busy

and piping Disconnect-PSSession ...

PS C:\Users\eperret> Get-PSSession -ComputerName $computerName -Credential $credential | Disconnect-PSSession

 Id Name            ComputerName    ComputerType    State         ConfigurationName     Availability
 -- ----            ------------    ------------    -----         -----------------     ------------
 46 WinRM7          computerNam     RemoteMachine   Disconnected  Microsoft.PowerShell          Busy
 47 WinRM4          computerNam     RemoteMachine   Disconnected  Microsoft.PowerShell          Busy
 48 WinRM2          computerNam     RemoteMachine   Disconnected  Microsoft.PowerShell          Busy
 49 WinRM5          computerNam     RemoteMachine   Disconnected  Microsoft.PowerShell          Busy
 50 WinRM3          computerNam     RemoteMachine   Disconnected  Microsoft.PowerShell          Busy

Answer 1

Try Disconnect-PSSession followed by Remove-PSSession :

Get-PSSession -ComputerName $computerName -Credential $credential | Disconnect-PSSession | Remove-PSSession

The Remove-PSSession cmdlet closes PowerShell sessions (PSSessions) in the current session. It stops any commands that are running in the PSSessions, ends the PSSession, and releases the resources that the PSSession was using. If the PSSession is connected to a remote computer, this cmdlet also closes the connection between the local and remote computers.

Answer 2

From get-help Exit-PSSession -full I can see :

Exit-PSSession [] , You cannot pipe objects to this cmdlet.

What I think you are looking for is:

Get-PSSession | Disconnect-PSSession
