Description
The Remove-PSSession cmdlet closes Windows 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, Remove-PSSession also closes the connection between the local and remote computers.
To remove a PSSession, enter the Name, ComputerName, ID, or InstanceID of the session.
If you have saved the PSSession in a variable, the session object remains in the variable, but the state of the PSSession is "Closed."
Parameters
-ComputerName <string[]>
Closes the PSSessions that are connected to the specified computers. Wildcards are permitted.
Type the NetBIOS name, an IP address, or a fully qualified domain name of one or more remote computers. To specify the local computer, type the computer name, "localhost", or a dot (.).

-Id <Int32[]>
Closes the PSSessions with the specified IDs. Type one or more IDs (separated by commas) or use the range operator (..) to specify a range of IDs
An ID is an integer that uniquely identifies the PSSession in the current session. It is easier to remember and type than the InstanceId, but it is unique only within the current session. To find the ID of a PSSession, use Get-PSSession without parameters.

-InstanceId <Guid[]>
Closes the PSSessions with the specified instance IDs.
The instance ID is a GUID that uniquely identifies a PSSession in the current session. The InstanceID is unique, even when you have multiple sessions running on a single computer.
The InstanceID is stored in the InstanceID property of the object that represents a PSSession. To find the InstanceID of the PSSessions in the current session, type "Get-PSSession | Format-Table Name, ComputerName, InstanceId".

-Name <string[]>
Closes the PSSessions with the specified friendly names. Wildcards are permitted.
Because the friendly name of a PSSession might not be unique, when using the Name parameter, consider also using the WhatIf or Confirm parameter in the Remove-PSSession command.

-Session <PSSession[]>
Specifies the session objects of the PSSessions to close. Enter a variable that contains the PSSessions or a command that creates or gets the PSSessions, such as a New-PSSession or Get-PSSession command. You can also pipe one or more session objects to Remove-PSSession.

<CommonParameters>
This command supports the common parameters: Verbose, Debug, ErrorAction, ErrorVariable, OutBuffer, OutVariable, WarningAction, and WarningVariable. For more information, see about_CommonParameters.
Inputs and Outputs
The input type is the type of the objects that you can pipe to the cmdlet. The return type is the type of the objects that the cmdlet returns.
|
Inputs |
System.Management.Automation.Runspaces.PSSession You can pipe a session object to Remove-PSSession. |
|
Outputs |
None Remove-PSSession does not return any objects. |
Notes
The ID parameter is mandatory. You cannot type "remove-pssession" without parameters. To delete all the PSSessions in the current session, type "Get-PSSession | remove-pssession".
A PSSession uses a persistent connection to a remote computer. Create a PSSession to run a series of commands that share data. For more information, see about_PSSessions.
PSSessions are specific to the current session. When you end a session, the PSSessions that you created in that session are forcibly closed.
Example 1
| Copy Code |
|
|---|---|
C:\PS>remove-pssession -id 1, 2 Description ----------- This command removes the PSSessions that have IDs 1 and 2. |
|
Example 2
| Copy Code |
|
|---|---|
C:\PS>get-pssession | remove-pssession - or - C:\PS> remove-pssession -session (get-pssession) - or - C:\PS> $s = get-pssession C:\PS> remove-pssession -session $s Description ----------- These commands remove all of the PSSessions in the current session. Although the three command formats look different, they have the same effect. |
|
Example 3
| Copy Code |
|
|---|---|
C:\PS>$r = get-pssession -computername Serv* $r | remove-pssession Description ----------- These commands close the PSSessions that are connected to computers that have names that begin with "Serv". |
|
Example 4
| Copy Code |
|
|---|---|
C:\PS>get-pssession | where {$_.port -eq 80} | remove-pssession
Description
-----------
This command closes the PSSessions that are connected to port 80. You can use this command format to identify PSSessions by properties other than ComputerName, Name, InstanceID, and ID.

Example 5
| Copy Code |
|
|---|---|
C:\PS>get-pssession | ft computername, instanceID -auto

C:\PS> remove-pssession -InstanceID fc4e9dfa-f246-452d-9fa3-1adbdd64ae85
Description
-----------
These commands show how to close a PSSession based on its instance ID (RemoteRunspaceID).
The first command uses the Get-PSsession cmdlet to get the PSSessions in the current session. It uses a pipeline operator (|) to send the PSSessions to the Format-Table cmdlet (alias: ft), which formats their ComputerName and InstanceID properties in a table. The AutoSize parameter ("auto") compresses the columns for display.
From the resulting display, the administrator can identify the PSSession to be closed, and copy and paste the InstanceID of that PSSession into the second command.
The second command uses the Remove-PSSession cmdlet to remove the PSSession with the specified instance ID.

Example 6
| Copy Code |
|
|---|---|
C:\PS>function EndPSS { get-pssession | remove-pssession }
Description
-----------
This function deletes all of the PSSessions in the current session. After you add this function to your Windows Powershell profile, to delete all sessions, just type "endpss".
