Can someone describe a good pattern to compare $entry[X] to $entry[Y] to determine if they are the same? I'm trying to get readable summaries of my logs and don't want to spit out 400 identical lines.

```
foreach ($log in $logs) {

    $nm = $log.LogDisplayName

    $header = $log.LogDisplayName
    Write-Host $header
    Add-Content $output "$header Log Errors/Warnings, Past 48 Hours"

    $entries = $log.Entries | ? {$_.TimeWritten -gt ($(Get-Date).AddDays(-2)) -and (($_.EntryType -like "Error") -or ($_.EntryType -like "Warning"))}

    foreach ($entry in $entries) { 

        ***here is where I think I need to compare array elements***

    }

    out-string -inputobject $entries | add-content $output

```
