## Introduction

<img align="left" src="misc/logo/logo-128x128.png">

`nnn` (or `n³`) 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` can analyze disk usage, batch rename, launch apps and pick files. The [plugin repository](https://github.com/jarun/nnn/tree/master/plugins#nnn-plugins) 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](https://github.com/mcchrish/nnn.vim).

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

## Black magic! :dark_sunglasses:

- Load, sort, filter thousands of files instantly
- Type to navigate with automatic dir selection
- Select files from anywhere (not just a single dir)
- Never lose context - start where you quit `nnn`
- Edit and preview markdown, man page, html
- Open a file and auto-advance to the next
- Export (filtered) list of visible files
- find/fd/grep/ripgrep/fzf from `nnn` and list in `nnn`
- Unlimited bookmarks, plugins, cmds with custom hotkeys
- Write a plugin in any language you know
- Configure the middle mouse click to do anything
- Fuzzy search subtree and open a file (or its parent dir)
- Load four dirs with custom settings at once
- Notifications on cp, mv, rm completion
- Auto-sync selection to system clipboard
- Open text files detached in another pane/tab/window
- Create files/dirs/duplicates with parents (like `mkdir -p`)
- Toggle hidden with <kbd>.</kbd>, visit HOME with <kbd>~</kbd>, last dir with <kbd>-</kbd>
- Pin a frequently visited dir at runtime
- Mount any cloud storage service in a few keypresses
- Mount and modify archives
- Filter filtered entries
- Sort files by access time and inode change time
- Access selection from another instance of `nnn`
- Compile out features you don't need
- Watch matrix text fly or read fortune messages
- Configure in 5 minutes!

## Quickstart

1. [Install](https://github.com/jarun/nnn/wiki/Usage#installation) `nnn` and deps (if you need any).
2. Configure [cd on quit](https://github.com/jarun/nnn/wiki/Basic-use-cases#configure-cd-on-quit).
3. Use option `-e` in your alias to open text files in `$VISUAL`/`$EDITOR`/ vi. [Open detached](https://github.com/jarun/nnn/wiki/Basic-use-cases#detached-text) if you wish.
4. [Install plugins](https://github.com/jarun/nnn/tree/master/plugins#installing-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`](https://github.com/jarun/nnn/blob/master/plugins/nuke) with option `-c` (overrides `-e`).

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.
