## Introduction

`nnn` is a full-featured terminal file manager. It's tiny and nearly 0-config with an [incredible performance](https://github.com/jarun/nnn/wiki/Performance).

`nnn` is also a du analyzer, an app launcher, a batch renamer and a file picker. The [plugin repository](https://github.com/jarun/nnn/tree/master/plugins#nnn-plugins) 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](https://github.com/mcchrish/nnn.vim).

It runs smoothly on the Pi, [Termux](https://www.youtube.com/watch?v=AbaauM7gUJw), Linux, macOS, BSD, Haiku, Cygwin, WSL, across DEs and GUI utilities or a strictly CLI environment.

[**Wiki**](https://github.com/jarun/nnn/wiki).

## Quickstart

1. Install the [utilities you may need](https://github.com/jarun/nnn#utility-dependencies) based on your regular workflows.
2. Configure [cd on quit](https://github.com/jarun/nnn/wiki/Basic-use-cases#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](https://github.com/jarun/nnn/tree/master/plugins#installing-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 <kbd>h</kbd> <kbd>j</kbd> <kbd>k</kbd> <kbd>l</kbd>), <kbd>/</kbd>, <kbd>q</kbd> suffice. <kbd>Tab</kbd> creates, cycles contexts. <kbd>?</kbd> lists shortcuts.

#### Release packages

Packages for Arch Linux, CentOS, Debian, Fedora and Ubuntu are auto-generated with the [latest stable release](https://github.com/jarun/nnn/releases/latest).

#### 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](https://github.com/jarun/nnn/wiki/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](misc/auto-completion). Refer to your shell's manual for installation instructions.
