Powershell 2.0 - Where-Object：无法绑定参数 'FilterScript'

Question

我有脚本可以监控来自 txt 文件的服务是否运行

标准list.txt:

Amsp
LTService

Bellow 块适用于 Powershell 2.0/3.0

$servicesToMonitor = Get-Content "$scriptpath\standard list.txt"
$servicebool = $true
$serviceList =@()
$status = 0

foreach($s in $servicesToMonitor){
    $tempservice = Get-Service $s -ErrorAction SilentlyContinue | Select-Object -Property Name, Status 
    $serviceList += $tempservice
    if($tempservice.Status -like "Running"){
        #Write-Host $tempservice.Name "-" $tempservice.Status 
    }elseif($tempservice -ne $null){
        $servicebool = $false 
        #Write-Host $tempservice.Name "-" $tempservice.Status
    }
}

$serviceList 变量：

Name          Status
----          ----  
Amsp          Stopped
LTService     Running

但是，此块仅在 PowerShell 2.0 上失败

$faultyservice = $serviceList | where Status -ne "Running"
 write-host "CRITICAL:" $faultyservice
 $status = 2

Where-Object : Cannot bind parameter 'FilterScript'. Cannot convert the "Status" value of type "System.String" to type "System.Manageme
nt.Automation.ScriptBlock".

修改为：

$faultyservice = $serviceList | where-object {Status -ne "Running"}

然后得到：

The term 'Status' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name
, or if a path was included, verify that the path is correct and try again.

Answer 1

PowerShell 3.0 中引入了 Where-Object propertyName -op value 语法。

更改为：

... |Where-Object {$_.Status -ne 'Running'}
