it's probably not as obvious when you are just out of jail(which is a shame, being locked up should be exactly the time when you can educate yourself, but not in real life probably)

But using linux terminal as devbox doesnt mean you dont have access to modern auto-complete syntax lookups formating etc, there are vim/neovim/emacs with any kind of configurations for all of it, and it can be preconfigured by others with projects like https://github.com/AstroNvim/AstroNvim or https://github.com/syl20bnr/spacemacs

So if you know anyone in the same kind of situation, you can advise them to use that.
