多个服务器上的PowerShell - get-hotfix -错误处理

Question

我在检查多个服务器上的多个修补程序时遇到了脚本问题。有时我没有到服务器的rpc连接，在这种情况下，我希望将此信息记录到同一个输出文件中。有人能帮帮我吗？谢谢

$computers =  Get-Content -path C:\00-Scripts\printer\server.txt
$Patch = Get-Content -path C:\00-Scripts\printer\kb.txt
  
foreach ($computer in $computers) {
    foreach ($patch1 in $patch) {
        Try {
            if (get-hotfix -id $patch1 -ComputerName $computer -ErrorAction stop) {
                Add-content "$patch1 is Present in $computer" -path C:\00-Scripts\printer\Hotfix.txt
             }
             Else {
                 Add-content "$patch1 is not Present in $computer" -path C:\00-Scripts\printer\Hotfix.txt
             }
         }
         catch {
             Add-content "can not check $computer" -path C:\00-Scripts\printer\Hotfix.txt
         }
     }
}

在这种情况下，您需要首先检查是否可以访问计算机。如果是，循环遍历补丁程序以报告是否可以找到它们。在您无法到达机器中，在日志中只记录一个故障行，然后继续下一台计算机。

$computers = Get-Content -path 'C:\00-Scripts\printer\server.txt'
$Patch     = Get-Content -path 'C:\00-Scripts\printer\kb.txt'
$logFile   = 'C:\00-Scripts\printer\Hotfix.txt'
foreach ($computer in $computers) {
    if (Test-Connection -ComputerName $computer -Count 1 -Quiet) {
        foreach ($patch1 in $patch) {
            # use -ErrorAction SilentlyContinue here so $hotfix will either become $null or an object
            $hotfix = Get-HotFix -Id $patch1 -ComputerName $computer -ErrorAction SilentlyContinue
            if ($hotfix) {
                "$patch1 is Present in $computer" | Add-Content -Path $logFile
            }
            else {
                "$patch1 is not Present in $computer" | Add-Content -Path $logFile
            }
        }
    }
    else {
        "Can not check $computer" | Add-Content -Path $logFile
    }
}
