Group, get subtotal and output the final result as a table? - powershell

Question

I have following powershell script.
$groups = gc $fn |
Select -Property #{name='G1'; expression={$_.SubString(340, 7)}},
#{name='G2'; expression={$_.SubString(32, 2)}},
#{name='V1'; expression={$_.SubString(420, 8)}},
#{name='V2'; expression={$_.SubString(43, 11)}} |
group G1,G2
$groups | % {
$g = $_.Group | ? { [float]($_.V1) -ne 0 } | measure V1 -Sum #V2???
$_.Name, $g
}
However I want the result as following. How to include the sum of V2? How to generate the object list for the final result?
Name SumOfV1 SumOfV2
G1, G2 3243243 2432432
.....
Workable example:
ps | select -Property #{name='g1'; expression = {$_.Name}},
##{name='g2'; expression = {$_.Id}},
#{name='v1'; expression = {$_.PM}},
#{name='v2'; expression = {$_.WS}} |
group g1 | % {
[pscustomobject] #{
Name = $_.Name
Sum = $_.Group | Measure V1,V2 -Sum | select -ExpandProperty Sum
}
}

Piece of cake, don't even need to see your data to be honest. In your ForEach loop simply create a PSCustomObject to output down the pipe with 3 properties, the Name of the group, the sum of V1, and the sum of V2. It can be done as such:
$groups = gc $fn |
Select -Property #{name='G1'; expression={$_.SubString(340, 7)}},
#{name='G2'; expression={$_.SubString(32, 2)}},
#{name='V1'; expression={$_.SubString(420, 8)}},
#{name='V2'; expression={$_.SubString(43, 11)}} |
group G1,G2
$groups|ForEach{
[pscustomobject]#{
'Name'=$_.name
'V1Sum'=$_.group|measure V1 -sum|select -expand sum
'V2Sum'=$_.group|measure V2 -sum|select -expand sum
}
}
I fabricated data for testing (yay get-random!):
G1 G2 V1 V2
-- -- -- --
Happy Meals 97 20
Happy Meals 71 21
Happy Meals 24 54
Tickle Fight 87 19
Tickle Fight 14 18
Tickle Fight 25 0
Tickle Fight 78 51
This provided the output of:
Name V1Sum V2Sum
---- ----- -----
Happy, Meals 192 95
Tickle, Fight 204 88
