更改 Export-CSV 输出输出格式

Question

我正在编写一个 PowerShell 脚本，该脚本将使用 Export-Csv 命令将系统管理员列表输出到 CSV 文件。获取数据的脚本部分是：

Foreach ($Computer in $Computers){
  $Online = Test-Connection -ComputerName $Computer -Quiet
  if ($Online -eq "True"){
    $GroupName = Get-WmiObject win32_group -ComputerName $Computer | ? {$_.SID -eq 'S-1-5-32-544'} | Select-Object name -ExpandProperty name
    $LocalGroup =[ADSI]"WinNT://$Computer/$GroupName"
    $GroupMembers = @($LocalGroup.psbase.Invoke("Members"))
    $Members = $GroupMembers | foreach {$_.GetType().InvokeMember("Name", 'GetProperty', $null, $_, $null)}
    foreach ($Member in $Members){
      $obj = New-Object System.Object
      $obj | Add-Member -MemberType NoteProperty -Name "Computer" -Value $Computer
      $obj | Add-Member -MemberType NoteProperty -Name "AdminGroupMembers" -Value $Member
      $obj
    }
  }
}

}

Get-Admins | Export-Csv -NoTypeInformation c:\scripts\adm.csv -Encoding UTF8

当前输出的格式如下：

"Computer1", "Admin1"
"Computer1", "Admin2"
"Computer1", "Admin3"
"Computer1", "Admin4"
"Computer2", "Admin1"
"Computer2", "Admin2"
"Computer3", "Admin1"

我试图让输出看起来像这样：

"Computer1", "Admin1" , "Admin2" , "Admin3" , "Admin4"
"Computer2", "Admin1" , "Admin2"  
"Computer3", "Admin1" , "Admin2" , "Admin3"

有什么想法吗？

Answer 1

您的输出格式不是 CSV，因此Export-Csv 不是适合您的工具。试试这个：

Get-Admins | group { $_.Computer } | % {
  '{0},{1}' -f @($_.Group.Computer)[0], ($_.Group.AdminGroupMembers -join ',')
} | Out-File 'output.csv'

对于 PowerShell v2，您需要手动展开组属性：

Get-Admins | group { $_.Computer } | % {
  $computer = @($_.Group | select -Expand Computer)[0]
  $admins   = ($_.Group | select -Expand AdminGroupMembers) -join ','
  '{0},{1}' -f $computer, $admins
} | Out-File 'output.csv'
