Vista Tutorial - filter out text..

In this I want to filter out "0 KB" (e.g Those apps whose WS has not
changed in the specified $args [time])...but I am thinking my
construct is not working with objects quite right. Any input is
appreciated.


$then = ps | %{$_ | Select Name, WorkingSet}
sleep $args[0]
$now = ps | %{$_ | Select Name, WorkingSet}
$count = $now.count
$difference = ( 0..$count |
%{"WS diff is" + " " + $Now[$_].Name + " " + ( ( $then
[$_].WorkingSet / 1KB ) - ( $Now[$_].WorkingSet / 1KB ) ) + " " +
"KB"} )
$difference

[output like:]

..\WS_diff.ps1 1200
.....
WS diff is explorer -12 KB
WS diff is GoogleToolbarNotifier 0 KB
WS diff is GoogleUpdate 0 KB
WS diff is GoogleUpdaterService 0 KB
WS diff is gpowershell 0 KB
....
WS diff is powershell -16 KB

Try something like this

$then = Get-Process | Select Name, WorkingSet
#sleep $args[0]
Start-Sleep -Seconds 5
$now = Get-Process | Select Name, WorkingSet
for ($i=0; $i -lt $now.count; $i++){

## check names
if ($now[$i].Name -eq $then[$i].Name){
$diff = $now[$i].WorkingSet - $then[$i].WorkingSet
if ($diff -gt 0){
"WS diff is {0} {1} KB" -f $($now[$i].Name), $($diff/1kb)
Write-Host $now[$i].WorkingSet $then[$i].WorkingSet
}
}
}

I would recommend that you capture the Id also. That way you are comparing
the same process from run to run. Relying on the process name isn't very
reliable.

120> $sb = { gps | Select Name, Id, WorkingSet }
121> $then = &$sb
....
123> $now = &$sb
124> $ht=@{}; $then | %{$ht[$_.Id]=$_}
133> $now | ? {$ht[$_.Id] -and $ht[$_.id].WorkingSet -ne $_.WorkingSet} |
Select Name, @{n='Diff';e={$_.WorkingSet - $ht[$_.id].WorkingSet}} |
Sort Diff -desc | % { "WS diff for $($_.Name) is $($_.Diff/1KB) KB"}
