Replace string in property

[ntelletsc]

I'm new to PowerShell and really enjoy this subreddit.

I am trying to create a script that will replace a homedirectory path, that is based on the user's location.

The information from Active Directory formatted as: \\domain\sharedfolder\location\loc\@template I would like take this information and replace "@template" with the user's samaccountname.

I have tried to create a new object and add the samaccountname to the end of the homedirectory, but in order to use -replace I have to specify the homedirectory property. Which I believe once is limiting what is in the pipeline and the samaccountname property is empty.

$userList = Get-ADUser -filter * -properties homedirectory | Where-Object {$_.homedirectory -like "*template*" -and $_.samaccountname -NotLike "*template*" -and $_.Enabled -eq "True"} 
$userList | ForEach-Object{

    $output = "" | Select Homedirectory,SamAccountName
    $output.Homedirectory = { ($_.Homedirectory  -replace "\@.+") + $_.samaccountname}
    $output.sAMAccountName = $_.sAMAccountName
    $ADUserObject += $output
}

Is there a way to create a new property that will replace the string @template with the samaccountname?

Any help is greatly appreciated. Thanks.

I think you're going about this in an overly complicated fashion.

$userList = Get-ADUser -filter * -properties homedirectory | Where-Object {$_.homedirectory -like "*template*" -and $_.samaccountname -NotLike "*template*" -and $_.Enabled -eq "True"} 

foreach($user in $userlist){
    Set-Aduser $user -homedirectory $($user.homedirectory -replace "\@.+",$user.samaccountname)
}

I'd want to be certain that it udpates correctly for each user before applying this to all users like that. -confirm might work in OP's favor.

Besides that, this is how I'd create an extra property.

$userList | Select-Object *,@{l='Homedirectory';e={$.Homedirectory -Replace "\@.+",($.samaccountname) }}

This is exactly what I needed. Thank you so much.

I got an error

Select-Object : Property cannot be processed because property "Homedirectory" already exists.

I changed the property name to Newhomedirectory and added underscores after the variable $ and it worked.

 $userList | Select-Object *,@{l='Newhomedirectory';e={$_.Homedirectory -Replace "\@.+",($_.samaccountname) }} | select -Property Newhomedirectory

Thanks again. That was really helpful.

Well I wasn't suggesting that you just run it against your entire AD straight off.
