在Foreach循环中组合Powershell命令

Question

我对Powershell还是很陌生，想知道为什么它不起作用。 基本上，我有一个foreach循环，用于检查IIS是否正在运行，如果正在运行，则报告OS版本，并将其写到文件中。 但是，报告不正确。 似乎它获取了第一个项目（IIS状态和OS）的值，然后通过循环中的其他项目来填充它。

#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获取您的本地OS版本。 使用Get-WmiObject Win32_OperatingSystem -ComputerName $server来获取目标计算机的OS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"
}
