I've been using
nnn for a few months now, and I can't overhype it.
It's a no-frills, super-fast file manager that runs in your terminal. It's open source and written in C.
nnn in action
[Features] [Quickstart] [Plugins] [Documentation]
nnn (n³) is a full-featured terminal file manager. It's tiny and nearly 0-config with an incredible speed.
It is designed to be unobtrusive with smart workflows to match the trains of thought.
nnn can analyze disk usage, batch rename, launch apps and pick files. The plugin repository has tons of plugins to extend the capabilities further e.g. preview, (un)mount disks, find & list, file/dir diff, upload files.
It runs smoothly on the Pi, Termux (Android), Linux, macOS, BSD, Haiku, Cygwin, WSL, across DEs and GUI utilities or a strictly CLI environment.

The Quickstart guide is excellent.
