That’s a variable order. I prefer a more consistent order like a default section structure (which a lot of man pages adopt) and an alphabetical order for flags (which a lot of man pages also adopt).

When I open a manual it’s usually for: flags and argument ordering; argument format (for things like string format or globbing). Some manuals are short enough that it can serve as a guide, but most assumes domain knowledge.

What you want is a cheatsheet. And there’s a lot on the internet and even some tools that collect them. But most practitioners write shell aliases and functions
