Pre-defined Typed Object
The Measure-Object command outputs an object of type Microsoft.PowerShell.Commands.GenericMeasureInfo
function Display-FolderStats([string]$path){
$files = dir $path -Recurse | where {!$_.PSIsContainer}
$totals = $files | Measure-Object -Property length -sum
return $totals
}
Display-FolderStats "c:\temp"
PowerShell’s default format rules arrange it properties in a vertical manner
Count : 1
Average :
Sum : 592406
Maximum :
Minimum :
Property : Length
Custom Object
If you are not happy with the default display format, you can convert the object from a pre-defined type object to a custom one
function Display-FolderStats([string]$path){
$files = dir $path -Recurse | where {!$_.PSIsContainer}
$totals = $files | Measure-Object -Property length -sum
$stats = "" | Select path,count,size
$stats.path = $path
$stats.count = $totals.count
$stats.size = [math]::round($totals.sum/1MB, 2)
return $stats
}
Display-FolderStats "c:\temp"
The rendered results become
path count size
---- ----- ----
c:\temp 1 0.56
