`nnn` (_n³_) is a full-featured terminal file manager. It's tiny and nearly 0-config with an [incredible speed](https://github.com/jarun/nnn/wiki/Performance).

It is designed to be unobtrusive with smart workflows to match the trains of thought.

`nnn` can analyze disk usage, batch rename, launch apps and pick files. The plugin repository has tons of plugins to extend the capabilities further e.g. [preview](https://github.com/jarun/nnn/wiki/Live-previews), (un)mount disks, find & list, file/dir diff, upload files.

There are 2 independent (neo)vim plugins - [nnn.vim](https://github.com/mcchrish/nnn.vim) and [vim-floaterm nnn wrapper](https://github.com/voldikss/vim-floaterm#nnn).

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

## Quickstart

1. [Install](https://github.com/jarun/nnn/wiki/Usage) `nnn` and any dependencies you need. 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](https://github.com/jarun/nnn/wiki/Basic-use-cases#detached-text) if you wish.
3. Configure [`cd` on quit](https://github.com/jarun/nnn/wiki/Basic-use-cases#configure-cd-on-quit).
4. [Sync subshell `$PWD`](https://github.com/jarun/nnn/wiki/Basic-use-cases#sync-subshell-pwd) to `nnn`.
5. [Install plugins](https://github.com/jarun/nnn/tree/master/plugins#installation).
6. Use `-x` to sync selection to system clipboard, show notis on `cp`, `mv`, `rm` completion and set xterm title.
7. For a CLI-only environment, customize and use plugin [`nuke`](https://github.com/jarun/nnn/blob/master/plugins/nuke) with option `-c` (overrides `-e`).
8. Bid `ls` goodbye! `alias ls='nnn -de'` :sunglasses:
9. Visit the [Live previews](https://github.com/jarun/nnn/wiki/Live-previews) and [Troubleshooting](https://github.com/jarun/nnn/wiki/Troubleshooting) Wiki pages.

Don't memorize! Arrows, <kbd>/</kbd>, <kbd>q</kbd> suffice. <kbd>Tab</kbd> creates and/or cycles contexts. <kbd>?</kbd> lists shortcuts.
