Powershell Select-Object like two value - powershell

Question

first time posting here.
I'm stuck with what i thought would be a simple task, trying to list Computers in AD with one or another Membership.
I just want to look in my #Ring variable for two strings as such as 'UPGRADE' or 'RING_'
Is there a simple way to do this ?
Thanks,
For now my code is like that
Get-ADComputer -SearchBase $Base_recherche -Properties * -Filter * |
Select-Object #{name="Nom machine";expression={$_.Name}},
#{n="Dernière date de connexion";e={$_.LastLogonDate}},
#{n="Systeme exploitation";expression={$_.OperatingSystem}},
#{n="Version";expression={$_.OperatingSystemVersion}},
#{n="CheminAD";expression={$_.CanonicalName}},
#{n="Ring";e={$_.memberof -like '*UPGRADE*'}} |
Export-CSV $Chemin_Export -Encoding UTF8 -NoTypeInformation

Answer 1

It seems if you need to only choose AD objects with a membership of 'UPGRADE' or 'RING_' you will need to use the -Filter parameter to filter out the objects ahead of time.
Get-ADComputer -SearchBase $Base_recherche -Properties * -Filter 'memberof -like '*UPGRADE*' -or memberof -like '*RING_*'
This will give you just the objects that satisfy the condition.
EDIT
You can combine the above code with your Select-Object but just add both elements you are looking for.
#{name="Ring";expression={$_.memberof -like '*Ring_*'}},
#{name="Upgrade";expression={$_.memberof -like '*UPGRADE*'}}
This will give you the two columns in your CSV with TRUE/FALSE values per computer line. This way you can know which systems belong to corresponding groups.
ComputerName,Ring,UPGRADE
machineA,true,false
machineb,true,true
machinec,false,true

Get-ADComputer by default returns objects with these properties:
DistinguishedName, DNSHostName, Enabled, Name, ObjectClass, ObjectGUID, SamAccountName, SID, UserPrincipalName
By writing -Properties * you're asking for ALL properties, which is wasteful and time consuming.
Better ask for the extra properties you DO need
Below joins the MemberOf DN's that have either 'UPGRADE' or 'RING_' with a semi-colon as Ring property in the output
$properties = 'LastLogonDate', 'OperatingSystem', 'OperatingSystemVersion', 'CanonicalName', 'MemberOf'
Get-ADComputer -SearchBase $Base_recherche -Properties $properties -Filter * |
Select-Object #{Name = "Nom machine"; Expression = {$_.Name}},
#{Name = "Dernière date de connexion"; Expression = {$_.LastLogonDate}},
#{Name = "Systeme exploitation"; Expression = {$_.OperatingSystem}},
#{Name = "Version"; Expression = {$_.OperatingSystemVersion}},
#{Name = "CheminAD"; Expression = {$_.CanonicalName}},
#{Name = "Ring"; Expression = {($_.MemberOf -match 'UPGRADE|RING_') -join '; '}} |
Export-CSV -Path $Chemin_Export -Encoding UTF8 -NoTypeInformation
If you want your Ring property to be just True if there is any MemberOf that has either 'UPGRADE' or 'RING_' found or False otherwise, then change this
#{Name = "Ring"; Expression = {($_.MemberOf -match 'UPGRADE|RING_') -join '; '}}
into
#{Name = "Ring"; Expression = {[bool]($_.MemberOf -match 'UPGRADE|RING_')}}
