Class: Inspec::Resources::VBScript

Inherits:
PowershellScript show all
Defined in:
lib/resources/vbscript.rb

Overview

This resource allows users to run vbscript on windows machines. We decided not to use scriptcontrol, due to the fact that it works on 32 bit systems only: $script = new-object -comobject MSScriptControl.ScriptControl $script.language = “vbscript” $script.ExecuteStatement($Cmd)

For that reason, we call csript.exe directy with the script. Vbscript is embedded in Powershell to ease the file transfer and reuse powershell encodedCommand since train does not allow file upload yet.

We run cscript with /nologo option to get the expected output only with the version information.

Since Windows does not delete tmp files automatically, we remove the VBScript after we executed it
