nnn - supercharge your productivity!

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

Introduction

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

nnn is also a du analyzer, an app launcher, a batch renamer and a file picker. The plugin repository has tons of plugins and documentation to extend the capabilities further. You can plug new functionality and play with a hotkey. There's an independent (neo)vim plugin.

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

Quickstart

1. Install the utilities you may need based on your regular workflows.
2. Configure cd on quit.
3. Optionally open all text files in $VISUAL (else $EDITOR, fallback vi): export NNN_USE_EDITOR=1.
4. For additional functionality install plugins.
5. To copy selected file paths to system clipboard and show notis on cp, mv, rm completion use option -x.
6. For a strictly CLI environment, see plugin nuke. It's a sample opener you can customize.

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

Release packages

Packages for Arch Linux, CentOS, Debian, Fedora and Ubuntu are auto-generated with the latest stable release.

From source

Download the latest stable release or clone this repository (risky), install deps and compile. On Ubuntu 18.04:

$ sudo apt-get install pkg-config libncursesw5-dev libreadline-dev
$ sudo make strip install

To compile without libreadline:

$ sudo apt-get install pkg-config libncursesw5-dev
$ sudo make O_NORL=1 strip install

PREFIX is supported, in case you want to install to a different location.

See the developer guides for source verification, compilation notes on the Pi, Cygwin and other tips.

Shell completion

Completion scripts for Bash, Fish and Zsh are available. Refer to your shell's manual for installation instructions.
