I was never able to properly parse large man pages, I'm so happy that llms can now prepare half a usable command without spending an hour reading a time without a single usage example.
`tldr` is also great. It's essentially a collection of example invocations of *nix commands.
What I usually do when I have to read large man pages like bash(1) is I read them as PDFs:
man -Tpdf bash | zathura -
Replace zathura with any PDF viewer reading from stdin or just save the PDF. Hope that can be useful to someone!
