member-enumeration

I am writing a recursive function that goes through a directory and copies every file and folder in it. The first check I have in the function is to see if the path passed in has children. To find this out, I use the following method: [array]$arrExclude = @("Extras") Function USBCopy { Param ([string]$strPath, [string]$strDestinationPath) try { $pathChildren = Get-ChildItem -Path $strPath if($pathChildren.Length -gt 0) { foreach($child in $pathChildren) { if($arrExclude -notcontains $child) { $strPathChild = "$strPath\$child" $strDestinationPathChild = "$strDestinationPath\$child" Copy-Item

Let's say we have an array of objects $objects. Let's say these objects have a "Name" property. This is what I want to do $results = @() $objects | %{ $results += $_.Name } This works, but can it be done in a better way?

The most popular answer for this question involves the following Windows powershell code (edited to fix a bug): $file1 = Get-Content C:\temp\file1.txt $file2 = Get-Content C:\temp\file2.txt $Diff = Compare-Object $File1 $File2 $LeftSide = ($Diff | Where-Object {$_.SideIndicator -eq '<='}).InputObject $LeftSide | Set-Content C:\temp\file3.txt I always get a zero byte file as the output, even if I remove the $Diff line. Why is the output file always null, and how can it be fixed? PetSerAl , as he routinely does, has provided the crucial pointer in a comment on the question (with no intent of
