Powershell Group By Multiple Properties

Question

I am trying to determine if there\'s an easier way to write a Powershell function that groups an array by multiple properties and sums specified properties in the group, sim

Answer 1

I have the same, perhaps a bit simpler, I remove two |

$grouped = $ungrouped | group ID, ID2
$grouped | foreach {
    $b= $_.name -split ', '
    [pscustomobject] @{
         ID = $b[0];ID2 = $b[1]
        'Sum Value' = ($_.group | measure value -sum).sum
    }
}

One liner :

Import-Csv 'YourFile.csv' | Group-Object -Property ID,ID2 | % {$b=$_.name -split ', ';$c=($_.group | Measure-Object -Property value -Sum).Sum;[PScustomobject]@{ID=$b[0];ID2=$b[1];Sum=$c}}
