You call this scripting?

1. The following command is for you to add to a script. You should first identify any elements that should be parameterized, such as the computer name. Your final script should define the parameter, and you should create comment-based help within the script. Run your script to test it, and use the Help command to make sure your -comment-based help works properly. Don’t forget to read the help files referenced within this chapter for more information.

Here’s the command:

Example

Get-WmiObject Win32_LogicalDisk -comp $env:computername -filter "drivetype=3" |
Where { ($_.FreeSpace / $_.Size) -lt .1 } |
Select -Property DeviceID,FreeSpace,Size

Answer

$minimumFreePercent = $minimumFreePercent / 100

Get-WmiObject Win32_LogicalDisk -comp $computername -filter "drivetype=3" | Where-Object { ($_.FreeSpace / $_.Size) -lt $minimumFreePercent } | Select-Object -Property DeviceID,FreeSpace,Size
