在 foreach 循环中组合 powershell 命令

Question

我对powershell很陌生，我想知道为什么这不起作用。 基本上，我有一个 foreach 循环，用于检查 IIS 是否正在运行并报告操作系统版本（如果是），并将其写入文件。 但是，它没有正确报告。 似乎它获取了第一项（IIS 状态和操作系统）的值，然后通过我的循环中的其他项目填充它。

#Get List of Servers to Scan
$servers = (Get-Content e:servers.txt)
#Determine if IIS is Running
foreach($server in $servers){
$iis = get-wmiobject Win32_Service -ComputerName $server -Filter "name='IISADMIN'";
if($iis.State -eq "Running")
{$OSVer= [environment]::OSVersion.Version}
Write-Host "$server,$IISRun,$OSVer" | Out-File -FilePath "E:results.txt"
}

结果：

 Server1,true,5.2.3790.131072     <---- Correct
 Server2,true,5.2.3790.131072     <---- Correct 
 Server3,true,5.2.3790.131072     <---- Wrong OS reported (windows 2008)
 Server4,true,5.2.3790.131072     <---- Wrong OS reported (windows 2008)
 Server5,true,5.2.3790.131072     <---- IIS isn't installed here at all
 Server6,true,5.2.3790.131072     <---- IIS isn't installed here at all

感谢您的任何建议...

[environment]::OSVersion.Version获取本地操作系统版本。改用Get-WmiObject Win32_OperatingSystem -ComputerName $server来获取目标计算机的操作系统信息，例如：

foreach ($server in $servers)
{
    $iis = Get-WmiObject Win32_Service -ComputerName $server -Filter "name='IISADMIN'"
    $os = Get-WmiObject Win32_OperatingSystem -ComputerName $server
    $iisRunning = $iis.State -eq "Running"
    $osVersion = $os.Version
    Write-Host "$server, $iisRunning, $osVersion"
}
