我编写了一个脚本，用于优化断开连接或空闲时间超过60分钟的用户。我已经设置了这些参数，但过滤器运行良好;该脚本不是断开该服务器中的特定用户，而是将服务器断开连接为整体
我正在使用另外两个函数，其中一个我直接添加到脚本中。另一个来自Get-LoggedOnUser.ps1 Disconnect-LoggedOnUser和Get-LoggedOnUser旨在协同工作。我保留了注销脚本的说明。我已将此完整脚本包含在此GitHub gist
中非常感谢任何帮助或建议！ 以下所有相关代码：
Description
-----------
This command dot sources the script to ensure the Disconnect-LoggedOnUser function is available in your current PowerShell session
.EXAMPLE
Disconnect-LoggedOnUser -ComputerName server01 -Id 5
Description
-----------
Disconnect session id 5 on server01
.EXAMPLE
.\Get-LoggedOnUser.ps1 -ComputerName server01,server02 | Where-Object {$_.UserName -eq 'JaapBrasser'} | Disconnect-LoggedOnUser -Verbose
＆lt; #My script＃＆gt;
<#
.SYNOPSIS
Convert output from CMD's 'query.exe user' to usable objects.
.DESCRIPTION
Take the text based output returned by 'query.exe user' and convert it to objects that can be manipulated in PowerShell.
.PARAMETER Name
Computer name to run query.exe against.
.EXAMPLE
PS C:\> Convert-QueryToObjects -Name server01
ComputerName Username SessionState SessionType
------------ -------- ------------ -----------
server01 bobsmith Disconnected
server01 janedoe Active tcp-rdp
#>
function Disconnect-LoggedOnUser {
<#
.SYNOPSIS
Function to disconnect a RDP session remotely
.DESCRIPTION
This function provides the functionality to disconnect a RDP session remotely by providing the ComputerName and the SessionId
.PARAMETER ComputerName
This can be a single computername or an array where the RDP sessions will be disconnected
.PARAMETER Id
The Session Id that that will be disconnected

.EXAMPLE
. .\Disconnect-LoggedOnUser.ps1
Description
-----------
This command dot sources the script to ensure the Disconnect-LoggedOnUser function is available in your current PowerShell session
.EXAMPLE
Disconnect-LoggedOnUser -ComputerName server01 -Id 5
Description
-----------
Disconnect session id 5 on server01
.EXAMPLE
.\Get-LoggedOnUser.ps1 -ComputerName server01,server02 | Where-Object {$_.UserName -eq 'JaapBrasser'} | Disconnect-LoggedOnUser -Verbose
Description
-----------
Use the Get-LoggedOnUser script to gather the user sessions on server01 and server02. Where-Object filters out only the JaapBrasser user account and then disconnects the session by piping the results into Disconnect-LoggedOnUser while displaying verbose information.

答案 0 :(得分：2)
问题是H:\WindowsPowerShell\Get-LoggedOnUser.ps1 -ComputerName $Server| Disconnect-LoggedOnUser -Verbose未使用Where-Object进行过滤。因此，您需要保存需要断开连接的用户会话的信息，然后使用该过滤后的信息断开连接。
这是一种接近它的方法，内联评论。
