script to copy group from one user to other

hello,

i have a powershell script to copy all group from one user to second user.
i need to add to this script an exclusion to exclude a list of group to be copied.
ideally a txt file named groupexlusion.txt where i can add group to exlude like this:

group1
group2

so when i lunsh my script to copy groups from user 1 to user2, all group will be copied exept the group1 and group2 (if user1 is memeber of this 2 group)

here my script:

Import-Module ActiveDirectory
$ErrorActionPreference = "SilentlyContinue"

while ($ok -ne "non" ) {
    Write-Host 
    $usr1 = Read-Host "plz enter the username source" 
    $test = Get-ADUser -LDAPFilter "(sAMAccountName=$usr1)"
   
    If ($test -eq $Null) {
        while ($test -eq $Null) {
          Write-Host  
          Write-Host "user not exist"
          Write-Host
		  $usr1 = Read-Host "plz enter the username source" 
		  $test = Get-ADUser -LDAPFilter "(sAMAccountName=$usr1)"
	   }
    }
    Write-Host
    Write-Host "here the groups $usr1 is member:" 
        Get-ADPrincipalGroupMembership -Identity $usr1 | select-Object name
    Write-Host
    Write-Host	


    $usr2 = Read-Host "plz enter the username destination" 
    $test2 = Get-ADUser -LDAPFilter "(sAMAccountName=$usr2)"
   
    If ($test2 -eq $Null) {
    	while ($test2 -eq $Null) {
          Write-Host  
          Write-Host "user not exist"
          Write-Host
		  $usr2 = Read-Host "plz enter the username destination" 
		  $test2 = Get-ADUser -LDAPFilter "(sAMAccountName=$usr2)"
	}
    }


    Write-Host
    Write-Host "here the groups $usr2 is memeber : "
    Write-Host 
        Get-ADPrincipalGroupMembership -Identity $usr2 | select-Object name
    Write-Host
	Write-Host 
    
    
    
    
    do{
        $go = Read-Host "Would you copy groups from $usr1 to $usr2 ? plz respond 'oui' or 'non'"
    }
    while  (($go -ne "oui") -and ($go -ne "non"))
    
    if ($go -eq "oui") {
        Get-ADPrincipalGroupMembership -Identity $usr1 | % {Add-ADPrincipalGroupMembership -Identity $usr2 -MemberOf $_}
    }
    
    
    
    Write-Host
    Write-Host "here the groups $usr2 is now memeber : "
    Write-Host 
        Get-ADPrincipalGroupMembership -Identity $usr2 | select-Object name
    Write-Host 
    Write-Host "------------------------------------------------------------"
	Write-Host
    
    do{
    $ok = Read-Host "do you need to do this operation to other user ? plz respond 'oui' or 'non'"
    }
    while  (($ok -ne "oui") -and ($ok -ne "non"))
}

Try replacing line 55 with the following two lines.
$exclude = Get-Content groupexclusion.txt
Get-ADPrincipalGroupMembership -Identity $usr1 | ? {$exclude -notcontains $_.name} | % {Add-ADPrincipalGroupMembership -Identity $usr2 -MemberOf $_}
