Post Body

Hi r/powershell,

I have a script that periodically gets some things, and I want to keep the processed objects in memory and also on disk. But I only want to keep the last x objects, not all of them. Currently I'm doing it like this:

$TailLog = @()

While ($true) {

    $TailLog  = Get-Thing
    $TailLog  = $TailLog | Select-Object -Last 100

    $TailLog | Export-Csv -Path .\taillog.csv

}

Is there a better way to achieve this? This potentially can run once a second, so I was wondering if there is a more efficient / faster / resource friendly way.
