Powershell 不讀取 .txt 行

Question

我無法讓 PowerShell 運行這個 .txt 文件，我做錯了什么？ 我嘗試更改 .txt 的名稱並檢查通過的腳本，一切似乎都相同，但我不斷收到錯誤消息，指出“.txt 無效”

$POSName = "$PSScriptRoot\Bex.txt"

foreach ($POS in (Get-Content $POSName)) {
    $Bex = Get-Service -ComputerName $POSName | Where-Object { $_.name -eq "BexServ" }
}

If ($Bex -eq $null) {
    # Service does not exist
    Write-Host " doesn't exist." -ForegroundColor Red
} 
Else {
    # Service does exist
    Write-Host "The $($Bex.Name) service found." -ForegroundColor Green
           
    If ($Bex.Status -eq "Running") {
        # Stop Service
        Set-Service -status stopped -ComputerName $POSName -name $Box.Name -ErrorAction Stop

        Write-Host "The $($Bex.Name) successfully stopped."  -ForegroundColor Green 
    }
    else {
        #service already stopped
        If ($Bex.Status -eq "Stopped") {
            Write-Host "The $($Bex.Name) service already Stopped." -ForegroundColor Green
        }
    }
}

正如所評論的，您在循環中使用了錯誤的變量。 代碼讀取文本文件就好了，它是Get-Service無法處理-ComputerName參數中的文件路徑。

此外， if..else的放置應該在循環內，而不是在循環之后。

嘗試

$POSName = "$PSScriptRoot\Bex.txt"

foreach ($POS in (Get-Content $POSName)) {
    $Bex = Get-Service -ComputerName $POS | Where-Object { $_.name -eq "BexServ" }

    If (!$Bex) {
        # Service does not exist
        Write-Host " doesn't exist." -ForegroundColor Red
    } 
    Else {
        # Service does exist
        Write-Host "The $($Bex.Name) service found." -ForegroundColor Green
           
        If ($Bex.Status -eq "Running") {
            # Stop Service
            Set-Service -status stopped -ComputerName $POSName -name $Box.Name -ErrorAction Stop

            Write-Host "The $($Bex.Name) successfully stopped."  -ForegroundColor Green 
        }
        else {
            #service already stopped
            If ($Bex.Status -eq "Stopped") {
                Write-Host "The $($Bex.Name) service already Stopped." -ForegroundColor Green
            }
        }
    }
}

^{在Write-Host行中輸出計算機名 ( $POS ) 也可能是個好主意}
