PowerShell的：Outputing Sucess和错误

Question

我已经写了批量重命名AD组一个非常简单的PowerShell脚本，下面是代码

# 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，但我有麻烦的部分是输出。输出字符串被写入文件和控制台，但是如果发生错误（例如，新名称已存在），则错误不会写入文件，并且写入输出命令仍会运行。

我想知道是否有人知道这样做的更好方法？最终目标是输出到控制台并记录是否成功重命名组，如果出错则继续。

在此先感谢！

你或许可以改写你的foreach循环是这样的：

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 
    } 
}
