Here’s a good primer: https://www.freecodecamp.org/news/command-line-for-beginners/ More on reddit.com

macos is a descendant of BSD unix -- it's unix under the hood. terminal is the shell program that allows you to use the command line under the GUI. current versions of macos use zsh. it's not a programming language, it's a "shell." most people don't need to use terminal. if you do, you're probably either already a power user with experience on linux/unix or are doing something really weird with controls that macos doesn't normally expose in the settings dialogs. https://support.apple.com/en-au/guide/terminal/welcome/mac the question i'd ask is, do you need or want to become a fluent user of the command line? most average users of macos do not need the command line most of the time. like, do you really want to learn what this means or how to figure out what it means? /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" [for everybody watching: that's the install command for homebrew] if so, i'd suggest spinning up a linux virtual machine that you can afford to trash to learn the fundamentals, because protections on the command line are more limited than in the gui. although most linux distributions use bash instead of zsh, most of the skills will transfer, and you can even use zsh in linux.

If it’s for “noobs” why not go for fish shell?  zsh is a monster requires tons of configs and (from my experience) is one of the slowest. More on reddit.com

You can start learning about package managers, assuming you haven’t used one before. Homebrew is the package manager you need for macOS. Try installing a few apps (aka casks on homebrew) using the terminal. More on reddit.com
