Powershell - SET-ADUSER Modify samaccountname

Question

New to powershell and still trying to get the logic.

I would like to filter out the samaccountname's in active directory in a specific OU, that also contain "adm" at the end of the string (phil_test_adm). When the users are found i want to replace with the "adm" with "tst". So far i have the below, again i am struggerling with the logic.

import-module activedirectory
$Path = 'OU=Example, OU=Users,DC=uk,DC=random,DC=com'
$users = Get-ADUser -filter 'SamAccountName -like "*adm"' -SearchBase $Path | select-object samaccountname, name
#foreach ($user in $users) 
#{
#Set-ADUser $user.samaccountname -Replace { 
#if $user.sammaccountname -eq "*adm"  }

As you can see where foreach begins i have just been playing about. Thank you for any help!

Solution

Assuming your first few lines are working to retrieve the correct results, this foreach block should work:

foreach ($user in $users) 
{
    $newSamAccoutname = $user.SamAccountName.replace("adm","tst")
    Set-ADUser $user -Replace @{samaccountname=$newSamAccoutname} 
}
