How to sum only 2nd column values using powershell?

To sum the sizes do this:

$totalSize = ($report | Measure-Object Size(MB) -Sum).Sum

$total = 0 
$report | % {[float]$tmp = $_.Size(MB).TrimEnd( MB); $total += $tmp}

Then you can just add the $total object to your custom $report object before you convertTo-html and bango. Thanks for the neat script.

Only thing that confused me a little was your () your size property of $report makes PS think its a method, thus the quotes. Is not the best convention, but it works.

More explicitly :

...
[array]$report += $obj
}

$total = 0 
$report | % {[float]$tmp = $_.Size(MB).TrimEnd( MB); $total += $tmp}
$obj = new-object psobject 
add-member -inp $obj noteproperty Path Total Size: 
add-member -inp $obj noteproperty Size(MB) $total 
[array]$report += $obj
#display the table
...

Also, Remove | Sort Size -Descending for the total to appear on the bottom.

I had a similar need and here is my simple solution:

$stuff=get-stuff
$results=
    foreach ($item in $stuff) {
        $item | select column1,@{N=Column 2;E={$_.column2}},description,created,@{N=Size (GB);E={{0:N2} -f $_.sizegb}}
    }

$results_sorted=@($results | sort created)
$results_sorted+=$item | select @{N=column1;E={Totals}},@{N=Column 2;E={$null}},@{N=Description;E={$null}},@{N=Created;E={$null}},@{N=Size (GB);E={($results | Measure-Object size (gb) -Sum).Sum}}
$results_sorted | ft column1,Column 2,Description,Created,Size (GB)
