function Save-DbaDiagnosticQueryScript { <# .SYNOPSIS Save-DbaDiagnosticQueryScript downloads the most recent version of all Glenn Berry DMV scripts .DESCRIPTION The dbatools module will have the diagnostice queries pre-installed. Use this only to update to a more recent version or specific versions. This function is mainly used by Invoke-DbaDiagnosticQuery, but can also be used independently to download the Glenn Berry DMV scripts. Use this function to pre-download the scripts from a device with an Internet connection. The function Invoke-DbaDiagnosticQuery will try to download these scripts automatically, but it obviously needs an internet connection to do that. .PARAMETER Path Specifies the path to the output .PARAMETER Silent Use this switch to disable any kind of verbose messages .NOTES Author: André Kamman (@AndreKamman), http://clouddba.io dbatools PowerShell module (https://dbatools.io, clemaire@gmail.com) Copyright (C) 2016 Chrissy LeMaire This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
