:dolphin: The missing terminal file manager for X.

n³ - supercharge your productivity!

type-to-nav & du (click to see demo video)

Introduction

nnn (or n³) 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 (Android), Linux, macOS, BSD, Haiku, Cygwin, WSL, across DEs and GUI utilities or a strictly CLI environment.

Black magic! 🕶️

1. Load, sort, filter thousands of files instantly
2. Type to navigate with automatic dir selection
3. Select files from anywhere (not just a single dir)
4. Edit and preview markdown, man page, html
5. Open a file and auto-advance to the next
6. Export (filtered) list of visible files
7. Find files by mime-type and list in nnn
8. Unlimited bookmarks, plugins, commands with custom hotkeys
9. Write a plugin in any language you know
10. Configure the middle mouse click to do anything
11. Fuzzy search subtree and open the dir of a file
12. Load four dirs with custom settings at once
13. Notifications on cp, mv, rm completion

15. Open text files detached in another pane/tab/window
16. Create files/dirs/duplicates with parents (like mkdir -p)
17. Toggle hidden with ., visit HOME with ~, last dir with -
18. Pin a frequently visited dir at runtime
19. Mount any cloud storage service in a few keypresses
20. Mount and modify archives
21. Filter filtered entries
22. Sort files by access time and inode change time
23. Access selection from another instance of nnn

Quickstart

1. Install optional deps (if you need any).
2. Configure cd on quit.
3. Use option -e in your alias to open text files in $VISUAL/$EDITOR/ vi. Open detached if you wish.
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.

sudo apt-get install pkg-config libncursesw5-dev libreadline-dev
sudo make 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.
