Comparing versions in PowerShell

Was recently asked on twitter how to compare properties of an object in the version format  (ie >= Well, as the property was string, which came into my mind was to remove the point. Something like

(Get-WmiObject win32_pnpsigneddriver |
Where-Object {(($_.DriverVersion).replace(‘.’,”)) -ge ‘3211’}).DriverVersion

Well, this solution will fail in some cases , as if you have NULL or other chars in the property. So, doing a better research, I found a post from Shay Levy (Actually he helped someone else)

You can use the [version] type in Powershell to perform the operation Alegre (as showing in the post above)

(Get-WmiObject win32_pnpsigneddriver |
Where-Object {[version]$_.DriverVersion -ge [version]’1.0.20′}).DriverVersion

Awesome !!!
