Linux

I mean, I'm not a big fan of bash, the most likely default shell, so my advice would be to explore some alternate shells.

I am a little surprised completions aren't working in bash by default, but yeah idk if it's possible to get the cycling through suggestions. double tap tab and it should at least list the options though.

I'd recommend you hop between some shells and see what you like. most distros tend to keep the default shell pretty vanilla, the most change you'll get is maybe zsh with some nicer defauls.

nushell is great and would be my first recommendation. everything is structured like powershell, but way less verbose and more emphasis on integrating the existing cli ecosystem than pwsh's commandlets for everything.

fish or oh-my-zsh are things other people recommend. you don't get structured data but they do give a better completion experience and other nice things

I want to like xonsh, and used it for a few years, but it has the same problems pwsh has with separate ecosystems of structured commands and unstructured text. if you're a python person though I'd consider it too though.
