Powershell：输出成功和错误

Question

我写了一个非常简单的 Powershell 脚本来批量重命名 AD 组，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
}

重命名部分工作正常，但我遇到问题的部分是输出。输出字符串同时写入文件和控制台，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 write-output 命令仍然运行。

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和文件，说明组是否成功重命名，如果出错则继续。

提前致谢！

你可以这样重写你的 foreach 循环：

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
    }
}
