By making use of the dbo.InstanceList in my DBA database I am able to target instances, by SQL Version, OS Version, Environment, Data Centre, System, Client or any other variable I choose. An agent job that runs every night will automatically pick up the instances and the scripts that are marked as needing installing. This is great when people release updates to the above scripts allowing you to target the development environment and test before they get put onto live.
I talked to a lot of people in Hannover and they all suggested that I placed the scripts onto GitHub and after some how-to instructions from a few people (Thank you Luke) I spent the weekend updating and cleaning up the code and you can now find it on GitHub here
Check out his solution, especially if you do not already have an administrative database on your instances.
