基本输出重定向

Question

我搜索并放在一起的PowerShell脚本来检查服务器列表中是否运行Windows服务（SNARE）。此时，如果脚本没有错误，脚本将打印“Snare正在运行”，如果遇到错误，脚本会显示“未安装/关闭”。我还在寻找的是，如果脚本不会以错误结尾，我能以某种方式获取状态的输出（下例）并打印“Snare is stopped”？

Status Name    DisplayName 
------ ----    ----------- 
Stopped SNARE    SNARE

#Powershell 
$serverList = gc Final.txt 
$collection = $() 
foreach ($server in $serverList) { 
    $status = @{ 
    "ServerName" = $server 
    "TimeStamp" = (Get-Date -f s) 
    } 
    if (Get-Service -Name SNARE -ComputerName $server -EA SilentlyContinue) { 
    $status["Results"] = "Snare is running" 
    } else { 
    $status["Results"] = "Not installed/Powered off" 
    } 
    New-Object -TypeName PSObject -Property $status -OutVariable serverStatus 
} 

Answer 1

从Get-Service输出分配给一个变量，并抓住​​从该Status属性：

if (($snare = Get-Service -Name SNARE -ComputerName $server -EA SilentlyContinue)) 
{ 
    $status["Results"] = "Snare is running" 
    $status["Status"] = $snare.Status 
} 
else 
{ 
    $status["Results"] = "Not installed/Powered off" 
    $status["Status"] = "Unknown" 
}
