Introduction

nnn (or n³) is a full-featured terminal file manager. It's tiny and nearly 0-config with an incredible performance.

nnn can analyze disk usage, batch rename, launch apps and pick files. The plugin repository has tons of plugins and documentation to extend the capabilities further e.g. preview hovered, (un)mount disks, find & list, file/dir diff, upload files. There's an independent (neo)vim plugin.

It runs smoothly on the Pi, Termux (Android), Linux, macOS, BSD, Haiku, Cygwin, WSL, across DEs and GUI utilities or a strictly CLI environment.

Quickstart

  1. Install nnn and deps (if you need any). All files are opened with the desktop opener by default.
  2. Add option -e to your alias to open text files in $VISUAL/$EDITOR/ vi. Open detached if you wish.
  3. Configure cd on quit.
  4. Install plugins.
  5. Use option -x to copy selected file paths to system clipboard and show notis on cp, mv, rm completion.
  6. For a CLI-only environment, customize and use plugin nuke with option -c (overrides -e).

Don't memorize! Arrows (or h j k l), /, q suffice. Tab creates, cycles contexts. ? lists shortcuts.
