PowerShell – PowerShell Installed/Compatible Version

Possibly one of my important commands is to find out what version I have available on the computer.

There are various ways to get this and some are rather long and arduous in comparison

clear

Write-Output "Get-Host (Really Only For 1.0, use once of the two below instead)"
     get-host | Format-Table name, version -AutoSize

Write-Output "`nPSVersionTable.PSVersion (If All you care about is the version)"
     $PSVersionTable.PSVersion

Write-Output "`nGet-PSVersion"
     function Get-PSVersion {
          if (test-path variable:psversiontable) {$psversiontable.psversion} else {[version]"1.0.0.0"}
     }
     Get-PSVersion

Write-Output "`nPSVersionTable"
     $PSVersionTable | format-table -AutoSize

Write-Output "`nPSVersionTable - Custom Hash Table"
     $system = @{
          "PS Version" = $PSVersionTable.PSVersion
          "PS Compatible Versions" = $PSVersionTable.PSCompatibleVersions
     }

     $system | format-table -AutoSize -HideTableHeaders

This will display something like this:

Get-Host (Really Only For 1.0, use once of the two below instead)
     Name                        Version
     ----                        -------
