Exciting you're interested in the terminal. Personally I find it an invaluable tool, it's powerful and versatile, suitable for almost any task. So as you learn, I'd encourage you to be concious about what you find interesting or fun, whether it is the coding-, problem solving-, automation-part, or an entiely different aspect.
There are several gamified introductions to programming, scripting and using the shell, which may be a good start. Some of my favourites (off the top of my head) are:
- "The Bandit" on Over the Wire to get familiar with the basics of the shell (terminal).
- Rustlings a collection of small exercises, and a great intro to tge Rust programming language
