Question

我对powershell很新，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。它似乎获取第一个项目（IIS状态和操作系统）的值，然后通过我的循环中的其他项填充它。

#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为您提供本地操作系统版本。请使用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"
}

在Foreach循环中组合Powershell命令
