如何使用Powershell進行多個到多個CSV文件的合併？

Question

我有兩個不同的CSV。一個是全球團體，地方團體和系統的報告。另一個是用戶，登錄ID和全局組的列表。

正如您所看到的，全局AD組是常用列，並且在這兩個文件中都標記爲「成員」。成員中的一些項目實際上是本地用戶或域用戶。需要將本地用戶過濾掉，並且需要將域用戶移植到結果中。

什麼使這項任務困難的是，聯接是多對多。另外，我需要能夠輕鬆地向腳本添加新列。我已經知道如何獲取您創建的任何腳本的輸出，並根據需要對列進行重新排序。

理想情況下，每個CSV文件中的列應該無關緊要，腳本應該基於公共列將兩個文件中的所有列連接在一起。雖然，如果在調用函數時可以指定公共列，那將會很好。

所以樣本數據會看起來像：

$CSV1 
"Members","LocalGroup","System" 
"System1\local-user","Guests","System1" 
"adminaccounts","Administrators",System2" 
"adminaccounts","Auditors","System2" 
"System3\User1","Administrators","System3" 
"System3\Temp","Guests","System3" 
"System4\Temp","Guests","System4" 
"System5\Temp","Guests","System5" 
"Domain1\ngd","Users","System6" 
"Domain1\Group1","Administrators","System7" 
"Domain1\Group1","Administrators","System8"

"Domain1\Group4","Administrators","System4" 
"Domain2\Group1","Administrators","System5" 
"Domain2\Group1","Administrators","System6" 
"Domain2\Group1","Administrators","System2"

你可以使用Join-Collections script。

$csv1 = import-csv csv1.csv 
$csv2 = import-csv csv2.csv 
$collection = Join-Collections -FirstCollection $csv1 -FirstJoinColumn Members -SecondCollection $csv2 -SecondJoinColumn Members 
$collection | export-csv result.csv
