powershell - ForEach循环的日志输出

Question

下面的代码可远程获取计算机信息。我无法将其发送输出到日志文件。另外，如何将所有未查询的计算机记录在单独的日志文件中？

   Code: 

   $ArrComputers =  gc .\computernames.txt

  Clear-Host
  ForEach ($Computer in $ArrComputers) 
  { 
$computerSystem = get-wmiobject Win32_ComputerSystem -Computer $Computer
$computerBIOS = get-wmiobject Win32_BIOS -Computer $Computer
$Version = Get-WmiObject -Namespace "Root\CIMv2" -Query "Select * from Win32_ComputerSystemProduct" -computer $computer | select version 

 write-host "System Information for: " $computerSystem.Name   -BackgroundColor DarkCyan
    "-------------------------------------------------------"

    "Model: " + $computerSystem.Model
    "Serial Number: " + $computerBIOS.SerialNumber
    "Version: " + $Version

    ""
    "-------------------------------------------------------"

      }

Answer 1

记录非常简单。您只需要将输出存储在变量中，然后使用Out-File cmdlet:

$ArrComputers = gc .\computernames.txt
$OutputLog = ".\output.log" # Main log
$NotRespondingLog = ".\notresponding.log" # Logging "unqueried" hosts

$ErrorActionPreference = "Stop" # Or add '-EA Stop' to Get-WmiObject queries
Clear-Host

ForEach ($Computer in $ArrComputers) 
{
    try
    {
        $computerSystem = get-wmiobject Win32_ComputerSystem -Computer $Computer
        $computerBIOS = get-wmiobject Win32_BIOS -Computer $Computer
        $Version = Get-WmiObject -Namespace "Root\CIMv2" `
            -Query "Select * from Win32_ComputerSystemProduct" `
            -computer $computer | select -ExpandProperty version
    }
    catch
    {
        $Computer | Out-File -FilePath $NotRespondingLog -Append -Encoding UTF8
        continue
    }

    $Header = "System Information for: {0}" -f $computerSystem.Name

    # Outputting and logging header.
    write-host $Header -BackgroundColor DarkCyan
    $Header | Out-File -FilePath $OutputLog -Append -Encoding UTF8

    $Output = (@"
-------------------------------------------------------

Model: {0} 
Serial Number: {1} 
Version: {2} 

-------------------------------------------------------

"@) -f $computerSystem.Model, $computerBIOS.SerialNumber, $Version

    # Ouputting and logging WMI data
    Write-Host $Output
    $Output | Out-File -FilePath $OutputLog -Append -Encoding UTF8
}
