Rename users / Searching and replacing with regex
  1. $regex = '(?<=CN=)[A-Z][a-z]*\s\([A-Z][a-z]*\)\s[A-Z][a-z]*' 
  2. $regexr = '\s\([A-Z][a-z]*\)' 
  3. $Users = Get-ADUser -Filter {Enabled -eq "True"} -Properties DistinguishedName, name, displayname | Where-Object { $_.DistinguishedName -match $regex} 
  4. ForEach ($User In $Users) 
  5. { 
  6.     $NM = $User.Name 
  7.     $NR = $NM -Replace $regexr,"" 
  8.     Rename-ADObject -Identity $user -NewName $NR 
  9. } 

I needed to clean up some usernames that had been created in the form "Johnny (John) Smith">  Get-ADUser -Filter {name -like "*(*)*"} got me close but I needed more precision. Regex provided great control.
