Out-String a result of a CMDLET and manipulate it in PowerShell -

i have variable gives me canocical name of object in active directory:

$lastou = get-adorganizationalunit -filter * -properties * |           sort { $_.whencreated } -descending |           select -first 1 {$_.canonicalname} |           out-string 

if run command write-host $lastouit indeeds gives me result expected:

@{$_.canonicalname=domain.local/microsoft/userz}

what i'm trying manipulate string have

microsoft

selected.

i used out-string method have result of command string.

after, use .split()-function manipulate result.

i $compname = $lastou.split(...).

however error:

method invocation failed because [selected.microsoft.activedirectory.management.adorganizationalunit] not contain method named 'split'.

this means result not string? wrong in command?

change select statement include -expandproperty, should give string instead of object.

change this

select -first 1 {$_.canonicalname} |out-string 

to this

select -expandproperty canonicalname -first 1
