Remove characters in display name after special character

Question

I am pretty new to powershell and hope I can get some ideas to my problem.

The display names of the users in our OU are set up to look like this: 'lastname title initial@department@location'
The display name is created manually, so the lastname, title and initial are not retrieved from any other field.

When users go to a different department and location we move them to a transfer OU, so the OU in that location can retrieve the account.
When we move the users we remove everything after the first @, so only the 'lastname title inital @' remain in the display name.

I have been looking for a script to remove everything after the first @ without changing anything in front of the @ but did not found anything.

Is this even possible? If yes, please let me know how to do this?

Thank you

Answer 1

You can also use a regex to accomplish the task:

$string = 'lastname title initial@department'  
  
$x = $string -replace "^(.+?@).*$", '$1'  

The result (in $x) is:

lastname title initial@

Answer 2

PowerShell Script:

$string = 'lastname title initial@department'
$string.Substring(0, $string.IndexOf('@'))

Write-Output $string

--------

input: lastname title initial@department
output: lastname title initial

Answer 3

Use Split in PowerShell

$string = 'lastname title initial@department@location'  
 $loginname = $string.Split('@')[0]  
  
 Write-Host `The user login name is: $loginname`  

In the variable $LoginNane you will have only lastname title initial

Answer 4

With Set-ADUser first you must to know which options you will update

The command would be something like this

Set-ADUser -Identity $loginname -Replace @{title="manager"}  

Here can see all the fields available

set-aduser
