I am trying to compare two folders at the hash level.
I get the hash information; Algorithm, Hash, Path $SourceDocs and $DestDocs both have the Algorithm, Hash, Path
When I run Compare-Object, the only value that gets passed along is SideIndicator
I had this running without the Hash, but files with similar names but different would pass as ok
cls
$Folder1 = "E:\Backups\Offsite"
$Folder2 = "E:\s3-drive\Backup\Compare"
$Folder3 = "E:\Backups\Temp_transfer"
Write-host
$time = Get-Date -Format HH:mm
Write-host $time
Write-host $Folder1
Write-host $Folder2
Write-host $Folder3
Write-host
Write-host
$time = Get-Date -Format HH:mm
Write-host $time
Write-host "Getting Directory Hash: " $Folder1
$SourceDocs = Get-ChildItem –Path $Folder1 | foreach {Get-FileHash –Path $_.FullName -Algorithm MD5}
Write-host
Write-host "Results for: " $Folder1
$SourceDocs
Write-host
Write-host
$time = Get-Date -Format HH:mm
Write-host $time
Write-host "Getting Directory Hash: " $Folder2
$DestDocs = Get-ChildItem –Path $Folder2 | foreach {Get-FileHash –Path $_.FullName -Algorithm MD5}
Write-host
Write-host
Write-host "Results for: " $Folder2
$DestDocs
Write-host
Write-host
$time = Get-Date -Format HH:mm
Write-host $time
Write-host "Comparing..."
Compare-Object -ReferenceObject $SourceDocs.Hash -DifferenceObject $DestDocs.Hash -IncludeEqual -Property path, hash, SideIndicator -PassThru
Write-host
$time = Get-Date -Format HH:mm
Write-host $time
Write-Host "These Files do not require action" -ForegroundColor Yellow
Compare-Object -ReferenceObject $SourceDocs.Hash -DifferenceObject $DestDocs.Hash -IncludeEqual -Property path, hash, SideIndicator -PassThru |
Where-Object { $_.SideIndicator -eq '==' } | Select-Object -Property path, hash, SideIndicator |
foreach-object -process{
Write-Host $_.path $_.hash $_.SideIndicator}
Write-host
$time = Get-Date -Format HH:mm
Write-Host "Duplicate Files to" -ForegroundColor Yellow -NoNewline; Write-Host " " $Folder1 -ForegroundColor Cyan
Compare-Object -ReferenceObject $SourceDocs.Hash -DifferenceObject $DestDocs.Hash -IncludeEqual -Property path, hash, SideIndicator -PassThru |
Where-Object { $_.SideIndicator -eq '<=' } | Select-Object -Property path, hash, SideIndicator |
foreach-object -process{

Write-host

Where-Object { $_.SideIndicator -eq '=>' } | Select-Object -Property path, hash, SideIndicator |
foreach-object -process{
Write-Host $_.path $_.hash $_.SideIndicator}
Break
And this is the output

Copy Files to E:\Backups\Offsite

The whole idea here is to compare the two folders and take one of 3 options:
Any insight would be appreciated
Update...
The Get-FileHash now looks like this:
$SourceDocs = Get-ChildItem -path $Folder1 -File | foreach {
Get-FileHash –Path $_.FullName -Algorithm MD5
New-Object PSCustomObject -Property @{
"DisplayName" = (Split-Path $_.FullName -Leaf -Resolve)}}
for some reason i could not get the name only to show so i used the New-Object and forced it
and the compare statement had to be adjusted too:
$compare = Compare-Object -ReferenceObject $SourceDocs -DifferenceObject $DestDocs -Property Hash -IncludeEqual -PassThru | Select-Object Hash, SideIndicator, Path
to
$compare = Compare-Object -ReferenceObject $SourceDocs -DifferenceObject $DestDocs -Property Hash -IncludeEqual -PassThru | Select-Object Hash, SideIndicator, DisplayName
UPDATE
Taken from the part where you are comparing, I think this will give you the wanted output:
Write-host "Comparing..."
$compare = Compare-Object -ReferenceObject $SourceDocs -DifferenceObject $DestDocs -Property Hash -IncludeEqual -PassThru | Select-Object Hash, SideIndicator, Path
Write-host
$doNothing = $compare | Where-Object { $_.SideIndicator -eq '==' }
if ($doNothing) {
Write-Host "These Files do not require action" -ForegroundColor Yellow
$doNothing | Format-Table -AutoSize
}
$doCopy = $compare | Where-Object { $_.SideIndicator -eq '<=' }
if ($doCopy) {
Write-Host "Copy these files" -ForegroundColor Cyan
$doCopy | Format-Table -AutoSize
}
$doDelete = $compare | Where-Object { $_.SideIndicator -eq '=>' }
if ($doDelete) {
Write-Host "Delete these files" -ForegroundColor Magenta
$doDelete | Format-Table -AutoSize
}
And to answer the question in the title: In your Compare-Object statement, you set it to compare only the Hash properties where you should compare the full objects $SourceDocs and $DestDocs
