Did you ever need to compare two arrays? Compare-Object might help. Check this out:
$array1 = 1..100 $array2 = 2,4,80,98 Compare-Object -ReferenceObject $array1 -DifferenceObject $array2 | Select-Object -ExpandProperty InputObject
The result is the content of $array1 minus the content of $array2.
To find out the array elements that are missing in $array1 but are present in $array2, try this:
$array1 = 1..100 $array2 = 2,4,80,98, 112 Compare-Object -ReferenceObject $array1 -DifferenceObject $array2 -ExcludeDifferent -IncludeEqual | Select-Object -ExpandProperty InputObject
