Powershell - How To Filter Output - powershell

Question

I need assistance in filtering what is going in to my output.
Here is my code:
$FolderPath = Get-ChildItem -Directory -Path "Z:\D482\F11\SECURE" -Recurse -Force
$Output = #()
ForEach ($Folder in $FolderPath) {
$Acl = Get-Acl -Path $Folder.FullName
ForEach ($Access in $Acl.Access) {
$Properties = [ordered]#{'Folder Name'=$Folder.FullName;'Group/User'=$Access.IdentityReference }
$Output += New-Object -TypeName PSObject -Property $Properties
}
}
$Output | ConvertTo-Csv | Out-File C:\Temp\Secured.txt
My output looks like this:
#TYPE System.Management.Automation.PSCustomObject
"Folder Name","Group/User"
"Z:\D482\F11\SECURE\QA\CDM\To_Load\Duals\Load_Completed","S-1-5-21-1275210071-879983540-1801674531-105509"
"Z:\D482\F11\SECURE\QA\Files\CDM\To_Load\Duals\Load_Completed","S-1-5-21-1275210071-879983540-1801674531-121910"
"Z\D482\F11\SECURE\QA\D482\To_Load\Duals\Load_Completed","DOMAIN\CXL3708"
In my output, I only want lines that contain our domain name ( as illustrated by the line with DOMAIN in it.
I have not been successful - either I get nothing, or I get error messages in the console.

here is one way to do the job ... [grin]
what it does ...
sets the constants
builds a parameter splat for the Get-ChildItem call
grabs the dirs from the source path
iterates thru the dir list
gets the acl list for the current dir & filters for those that start with the required domain name
note that i don't have a .IdentityReference property in my ACL, so i used .Owner instead.
iterates thru those acl items
builds a [PSCustomObject] for the current acl
sends that out to the $AccessInfo collection
displays the content of the above on screen
saves the collection to a csv file
the code ...
$SourcePath = $env:TEMP
$DomainName = $env:USERDOMAIN
$ReportFile = "SO_Erich_Powershell - How To Filter Output.csv"
$FullReportFile = Join-Path -Path $env:TEMP -ChildPath $ReportFile
$GCI_Params = #{
LiteralPath = $SourcePath
Directory = $True
Force = $True
Recurse = $True
ErrorAction = 'SilentlyContinue'
}
$DirList = Get-ChildItem #GCI_Params
$AccessInfo = foreach ($DL_Item in $DirList)
{
$AclList = Get-Acl -LiteralPath $DL_Item.FullName |
Where-Object {
$_.Owner -match "^$DomainName"
}
foreach ($AL_Item in $AclList)
{
[PSCustomObject]#{
DirName = $DL_Item.FullName
# my single system has no ".IdentityReference" property
# so i used ".Owner"
GroupOrUser = $AL_Item.Owner
}
}
}
# display the data
$AccessInfo
# send to a csv file
$AccessInfo |
Export-Csv -LiteralPath $FullReportFile -NoTypeInformation
truncated screen output ...
DirName GroupOrUser

truncated csv file content ...
