Powershell更改AD用户属性

Question

I need to search through all users in AD, find their attribute "mail" and in this attribute replace @hell.com to @heaven.com

I'm stuck at exporting and importing to csv...

Import-Module ActiveDirectory
get-aduser -Filter {samaccountname -like "gmaleev"} -properties * | Select-Object SamAccountName,mail | export-csv -NoTypeInformation d:\1.csv
$impfile = "d:\1.csv"
Import-CSV $impFile
foreach ($user in $users)
{
$sam = $user.samaccountname
$email = $user.mail
write-host "User $sam has mail $mail"
}

It doesn't work, why?

Answer 1

The current issue is that you are running a cmdlet to import the data but not saving it. Your ForEach cmdlet is not processing any data so you should have blank output except that of Import-CSV which should be outputing to console.

Also it seems redundant to export the data to import it again. I will presume that you have a reason for exporting it.

Import-Module ActiveDirectory
$impfile = "d:\1.csv"
$results = Get-AdUser -Filter {samaccountname -like "gmaleev"} -properties * | Select-Object SamAccountName,mail 
$results | export-csv -NoTypeInformation d:\1.csv
$results | foreach ($user in $users){
    $sam = $user.samaccountname
    $email = $user.mail
    write-host "User $sam has mail $mail"
}

This should address what you are showing. It will get the same data and save it to the variable $results . Export that data and then piping it to the ForEach to process

Your title suggets that you want to change user attributes. To do that you would need to use Set-Aduser . Depending on what your environment is this might not be the best way to manipulate email attributes.
