How to receive OU values separately in different columns via powershell? - powershell

Question

The powershell query I use to get the list of all the workstations registered in AD is on below:
Get-ADComputer -Filter {OperatingSystem -NotLike "*server*"} -Property * | Select-Object Name,SID,DistinguishedName,whenCreated,LastLogonDate | Export-CSV allworkstations2.csv -NoTypeInformation -Encoding UTF8
An example of "DistinguishedName" is like:
CN=500-AV,OU=Workstations,OU=SecondOU,OU=ThirdOU,OU=FourthOU,DC=myDC1,DC=myDC2
CN=600-AV,OU=FirstOU,OU=SecondOU,OU=ThirdOU,OU=FourthOU,OU=FifthOU,DC=myDC1,DC=myDC2
Please note that the number of OU values for each workstation can differ, can't say it is always 4. Edit: Maximum number of OU a workstation can have is 5.
I need all the OU values separately, as different columns (OU1, OU2, ... etc). In Excel, I was using this formula below to receive all the OU values in separate columns:
=TRIM(MID(SUBSTITUTE(MID($B2,FIND(",OU=",$B2)+4,FIND(",DC=",$B2)-FIND(",OU=",$B2)-4),",OU=",REPT(" ",999)),(COLUMN(A:A)-1)*999+1,999))
What I want is to get the OU values in different columns directly from the powershell. I couldn't find out the correct syntax to update my query accordingly. Any help would be appreciated.
Here is the version info:
Edit2: Example of expected output:
WorkstationName SID OU1 OU2 OU3 OU4 OU5 createdDate LastLogin
500-AV X Workstations SecondOU ThirdOU FourthOU null 1/1/2018 6/1/2018
600-AV X FirstOU SecondOU ThirdOU FourthOU FifthOU 1/1/2018 6/1/2018

now that you clarified things a tad, i think this does what you want. [grin]
what it does ...
creates two user objects to work with
delete this when you are ready to work with your data set. [grin]
iterates thru the user list
splits the DistinguishedName to get the OUs
makes the $OuList variable into an array even if there is only one OU
builds a custom object with the anticipated max number of OUs
you will need to determine that ahead of time.
sends that object out to the $Results collection
displays that collection
at that point, you have a collection that will gracefully export to a CSV file. [grin]
here's the code ...
$UserList = #(
[PSCustomObject]#{
ComputerName = '111-AV'
SID = '1-22-333'
DistinguishedName = 'CN=111-AV,OU=SolitaryOU,DC=myDC1,DC=myDC2'
DateCreated = '2011-11-11'
LastLogon = '2019-08-11'
}
[PSCustomObject]#{
ComputerName = '500-AV'
SID = '1234-5678-90'
DistinguishedName = 'CN=500-AV,OU=Workstations,OU=SecondOU,OU=ThirdOU,OU=FourthOU,DC=myDC1,DC=myDC2'
DateCreated = '2001-01-01'
LastLogon = '2019-08-08'
}
[PSCustomObject]#{
ComputerName = '666-AV'
SID = '777-888-999'
DistinguishedName = 'CN=666-AV,OU=Servers,OU=SrvOu2,OU=SrvOu3,OU=SrvOu4,OU=SrvOu5,DC=myDC1,DC=myDC2'
DateCreated = '1999-12-31'
LastLogon = '2019-08-20'
}
)
$Results = foreach ($UL_Item in $UserList)
{
[array]$OuList = #($UL_Item.DistinguishedName.Split(',')).
Where({$_ -match 'OU='}).
ForEach({$_.Split('=')[-1]}).
Trim()
[PSCustomObject]#{
ComputerName = $UL_Item.ComputerName
SID = $UL_Item.SID
OU_1 = $OuList[0]
OU_2 = $OuList[1]
OU_3 = $OuList[2]
OU_4 = $OuList[3]
OU_5 = $OuList[4]
DateCreated = $UL_Item.DateCreated
LastLogon = $UL_Item.LastLogon
}
}
$Results
output to screen ...
