active directory - Compare two organizational units with Powershell -

i compare 2 organizational units users. can user list command:

ou_number_1:  get-aduser -filter * -searchbase "ou=ou_number_1,ou=ou-sne_sharepoint,dc=vf,dc=local" | select samaccountname   ou_number_2:     get-aduser -filter * -searchbase "ou=ou_number_2,ou=ou-sne_sharepoint,dc=vf,dc=local" | select samaccountname 

i homonymous these lists. have put users in lists , compare them ? or better idea ?

to summary, list homonymous of ou's.

/update

try

$usergroup1 = get-aduser -filter * -searchbase "ou=ou_number_1,ou=ou-sne_sharepoint,dc=vf,dc=local" | select samaccountname   $usergroup2 = get-aduser -filter * -searchbase "ou=ou_number_2,ou=ou-sne_sharepoint,dc=vf,dc=local" | select samaccountname   $userinbothou = compare-object $usergroup1 $usergroup2 -includeequal 

be aware array $userinbothou contains powershell objects. when want samaccountname, must that:

foreach($user in $userinbothou) {     write-host $user.samaccountname } 

because samaccountname attribute.
