More PowerShell Runspace Fun

In the last article, we began to explore how to use custom runspaces in our PowerShell scripting. Is still believe that using cmdlets like Start-Job and Invoke-Command are preferred. Let PowerShell do the work. But, there may be situations where advanced scripters want to have more granular control over the process.

Last time, we looked at using runspaces sequentially. Like a background job, the results remain in the runspace, and you may want to keep things separate. You can also easily re-run the code in the runspace.

Here's a simple script.

#MeasureFolder.ps1
Param([string]$Path = '.')

$stat = Get-ChildItem -Path $Path -Recurse -File | Measure-Object -Property Length -Sum -Average

[PSCustomObject]@{
    PSTypeName   = 'folderInfo'
    Path         = Convert-Path $Path
    Files        = $stat.Count
    Size         = $stat.Sum
    Average      = $stat.Average
    Computername = [System.Environment]::MachineName
    Date         = Get-Date
}
