nnn - type less, do more, way faster

navigate-as-you-type & du (click to see demo video)

Introduction

nnn is a full-featured terminal file manager. It's tiny, extremely light and fast.

nnn is also a disk usage analyzer, a fuzzy app launcher, a batch file renamer and a file picker. The plugin repository has 30+ plugins to extend the capabilities further. There's an independent (neo)vim plugin.

It runs smoothly on the Raspberry Pi, Termux on Android, Linux, macOS, BSD, Cygwin and Linux subsystem for Windows. nnn works seamlessly with DEs and GUI utilities. It's nearly zero-config (with sensible defaults) and can be setup in less than 5 minutes.

Add to that an awesome Wiki!
