Question

我正在运行一个首先获取所有群组的脚本，然后获取这些已收集群组的所有成员并将其放入.csv。

我现在已经等了3个多小时了，甚至还不到一半...

以下是剧本。

Get-QADGroup -SizeLimit 0 -properties * | 
Select samaccountname| 
Export-CSV D:\Test_PowerShell\group.csv -NoTypeInformation

Get-Content "D:\Test_PowerShell\group.csv" | 
foreach-object {$group = $_ -replace '"', ""# grab current group name get-qadgroupmember $group -sizelimit 0 -indirect | 
`select-object samaccountname,@{n="GroupName";e={$group}}} | 
export-csv D:\Test_PowerShell\groupandmem.csv -notypeinformation

Answer 1

试试这个：

( Get-QADGroup -SizeLimit 0 ) | 
foreach-object {                    
                 $group = $_.samaccountname
                 get-qadgroupmember $_.samaccountname -sizelimit 0 -indirect | 
                 select-object samaccountname, @{n="GroupName";e={$group}}
               }

如果您使用的是PowerShell版本3.0 / 4.0 ，您可以尝试使用PowerShell工作流程（我没有对性能进行过任何大量测试，但理论上至少可以将速度提高一倍）：

workflow get-UserAndGroup 
{
   $a = inlinescript {   add-pssnapin Quest.ActiveRoles.ADManagement
                        Get-QADGroup -SizeLimit 0 | select -expa samaccountname
                    }                           

   foreach -parallel ( $group in $a ) 
   {                    
     inlinescript {
                    add-pssnapin Quest.ActiveRoles.ADManagement
                    Get-qadgroupmember $using:group -sizelimit 0 -indirect | 
                    select-object samaccountname, @{n="GroupName";e={$using:group}}
                  } 
    } 
}

像这样使用：

 get-UserAndGroup | select samaccountname, groupname | export-csv .\myfile.csv -notypeinformation

我的效果测试（包含5到50个用户的30个小组）：

PS C:\ps> workflow get-UserAndGroup 
{
   $a = inlinescript {   add-pssnapin Quest.ActiveRoles.ADManagement
                        Get-QADGroup  -SizeLimit 0 | select -expa samaccountname
                    }



   foreach -parallel ( $group in $a ) 
   {                    
     inlinescript {
                    add-pssnapin Quest.ActiveRoles.ADManagement
                    Get-qadgroupmember $using:group -sizelimit 0 -indirect | 
                    select-object samaccountname, @{n="GroupName";e={$using:group}}
                  } 
    } 
}

PS C:\ps> Measure-Command { get-UserAndGroup }
