If we want to extend our disk checking to multiple machines we can input the computer names via an array.

## listing 2.12
cls

$convert = 1MB
$computers = "pcrs2", "pcrs3", "pcrs4"
$threshold = 100

foreach ($computer in $computers) {
    $disks = Get-WmiObject -ComputerName $computer -Class Win32_LogicalDisk
    foreach ($disk in $disks) {
        $free = [int]($disk.Freespace/$convert)
        if ($free -lt $threshold){Write-Host "$computer $($disk.DeviceID) is low on diskspace"}
    }
}

We then do a simple foreach loop for each computer in the array and substitute its name into Get-WMIObject.  Note that the -Computername parameter of Get-WMIObject does not accept pipeline input so we need a foreach of some kind
