PowerShell的：Outputing Sucess和錯誤

Question

我已經寫了批量重命名AD組一個非常簡單的PowerShell腳本，下面是代碼

# This script will perform a bulk rename of AD groups. 
# Takes input from a csv file called "ADGroups.csv" with two columns, 
# first column labelled "ObjectGUID" and contains the GUID of the AD Group you wish to rename and 
# the second column is labeled "NewName" and contains the name that you want the group to be renamed to. 
# Outputs results to console and a file called ADGroupBulkRenameLog.txt 

$Groups = Import-Csv ADgroups.csv 

Foreach ($Group in $Groups) 
{ 
    $OldName = Get-ADGroup -Identity $Group.ObjectGUID | Select Name 
    Rename-ADObject -Identity $Group.ObjectGUID -NewName $Group.NewName 
    Set-ADGroup -Identity $Group.ObjectGUID -SamAccountName $Group.NewName 
    Write-Output ($OldName.Name + " has been renamed to " + $Group.NewName) | Tee-Object ADGroupBulkRenameLog.txt -Append 
} 

重新命名部分工作正常，但我有麻煩的部分是輸出。輸出字符串被寫入文件和控制檯，但是如果發生錯誤（例如，新名稱已存在），則錯誤不會寫入文件，並且寫入輸出命令仍會運行。

我想知道是否有人知道這樣做的更好方法？最終目標是輸出到控制檯並記錄是否成功重命名組，如果出錯則繼續。

在此先感謝！

你或許可以改寫你的foreach循環是這樣的：

foreach ($Group in $Groups) 
{ 
    try 
    { 
     $OldName = Get-ADGroup -Identity $Group.ObjectGUID | Select Name 
     Rename-ADObject -Identity $Group.ObjectGUID -NewName $Group.NewName 
     Set-ADGroup -Identity $Group.ObjectGUID -SamAccountName $Group.NewName 
     Write-Output ($OldName.Name + " has been renamed to " + $Group.NewName) | Tee-Object ADGroupBulkRenameLog.txt -Append 
    } 

    catch 
    { 
     Write-Output "Error: $_" | Tee-Object ADGroupBulkRenameLog.txt -Append 
    } 
}
