All three of these methods display the results in similar manners. My question is why in METHOD 01, I can't use Write-Output {$_.FullName}, instead, I have to use a ForEach-Object?

I have to use METHOD 01 to run it against a function that I created.

Clear-Host

#METHOD 01
Get-ChildItem -Path 'D:\' -Directory -Depth 0 | 
ForEach-Object{$_.FullName} | 
Sort-Object

#METHOD 02 (Sticking into Variable)
$AA = Get-ChildItem -Path 'D:\' -Directory -Depth 0
Write-Output $AA.FullName | 
Sort-Object

#METHOD 03 (Sticking into Variable)
$AA = Get-ChildItem -Path 'D:\' -Directory -Depth 0
ForEach($oItem in $AA)
{
    $oItem.FullName
}

    You can use Get-ChildItem | Write-Output -InputObject { $_.FullName }, which resolves the ambiguity between pipeline input and argument. Commented Aug 31, 2022 at 8:12
  • Zett42, I know I can use $Input.FullName to call it from a function. But how do I pass InputObject into my function? Get-ChildItem -Path 'D:\' -Directory -Depth 0 | MyFunction -InputObject {-FirstName $_.FullName -LastName $_.FullName } Commented Aug 31, 2022 at 8:50
  • Simplest way is a filter function: Filter MyFunction { $_ }. This would be a "do nothing" filter. For more complex stuff create an advanced function with a parameter that accepts pipeline input ([Parameter(ValueFromPipeline)] $InputObject). Commented Aug 31, 2022 at 9:15
  • Thanks and I agree on the advance function Zett42. I found this and it is what I am looking for. I am going to analyze it. Thank You and have a good night. Commented Aug 31, 2022 at 9:20
