We have a script that will run through the logical disks on a machine and return the free space. How do we run that multiple times?

$convert = 1MB
$computer = "pcrs2"
#$pause = 3600 ## 1 hour
$pause = 10 ## 10 seconds
for ($i=1; $i -le 12; $i++){
## iterate through results collection
$disks = Get-WmiObject -ComputerName $computer -Class Win32_LogicalDisk
Get-Date -DisplayHint Time
foreach ($disk in $disks) {
Write-Host "There are $([int]($disk.Freespace/$convert)) megabytes of free disk space on $($disk.DeviceID)"
}
Start-Sleep -Seconds $pause
}
If we take our script from last time and warp it in another loop we can control how many times it runs. In this case I’ve use a for loop with a counter that increments from 1-12. Within that loop we use get-date to display the time and then display the free space. PowerShell would run the loops continuously so we we use start-sleep to pause the script. For testing I used 10 seconds but you can choose any number of seconds – 3600 would be running it hourly.
It doesn’t take a lot of PowerShell to give some very useful functionality.
