powershell - Get-Process with total memory usage

Question

$Processes = get-process -computername $tag1 | Group-Object -Property ProcessName
foreach($Process in $Processes)
{
    $Obj = New-Object psobject
    $Obj | Add-Member -MemberType NoteProperty -Name Name -Value $Process.Name
    $Obj | Add-Member -MemberType NoteProperty -Name Mem -Value ($Process.Group|Measure-Object WorkingSet -Sum).Sum
    $Obj
}   

Currently, this displays memory usage in bytes, how can I change this to show something like:

76,592 KB

and also output everything that is autosized? (aligned to the left)

Answer 1

Format-Table can show expressions and auto-size the columns to fit the results:

On 64 bits:

get-process -computername $tag1 | Group-Object -Property ProcessName | 
    Format-Table Name, @{n='Mem (KB)';e={'{0:N0}' -f (($_.Group|Measure-Object WorkingSet64 -Sum).Sum / 1KB)};a='right'} -AutoSize

On 32 bits:

get-process -computername $tag1 | Group-Object -Property ProcessName | 
    Format-Table Name, @{n='Mem (KB)';e={'{0:N0}' -f (($_.Group|Measure-Object WorkingSet -Sum).Sum / 1KB)};a='right'} -AutoSize
