I'm an L1 tech and want to get more experience and practicing automating certain small processes. Adding users to a domain, removing them, resetting passwords. Very small stuff.

What are some resources I can look at for doing these things? Either making them myself, or more likely considering all the security implications I'd have to be dealing with, modules I can be using to do these tasks in CLI versus GUI? Any other ideas of small things I can be doing? I'm considering data manipulation w/interacting w/excel sheets as well as learning about APIs and how to work with them.

Any resources (books, videos, links, etc) would be appreciated.
