How to learn Batch Script?

Question

I would like to learn more about Batch Script, but I have difficulties finding more material on the internet. Where can I find more advanced material?

Answer 3

Arthur Siqueira I don't know batch scripting myself, so even if I could give you some resources, I wouldn't know how good they are myself.

So, see @Martin Taylor's answer instead. They have mentioned some links.
