Question

We are providing scripts to clients that will be working only in Powershell 2.0.

Through command we can ensure that powershell 2.0 is installed like below

$version = Get-host | Select-object Version

But if we provide script how to ensure that they are executing it from Powershell 2.0?

When executing the script , Powershell 2.0 features may give script errors while initiating the script itself.Isn’t it?

Answer 1

You can annotate your script with #requires and state that it shouldn’t run on anything less than PowerShell v2:

#requires -Version 2.0

_{(Side note: This is surprisingly hard to find even if you know vaguely that it exists.)}
