nnn - Supercharge your productivity!

[Features] [Quickstart] [Plugins] [Documentation]

nnn (n³) is a full-featured terminal file manager. It's tiny and nearly 0-config with an incredible speed.

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, (un)mount disks, find & list, file/dir diff, upload files. A patch framework hosts sizable user-submitted patches which are subjective in nature.

There are 2 independent (neo)vim plugins - nnn.vim and vim-floaterm nnn wrapper.

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

Quickstart

1. Install 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 if you wish.
3. Configure cd on quit.
4. Sync subshell $PWD to nnn.
5. Install plugins.
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 with option -c (overrides -e).
8. Bid ls goodbye! alias ls='nnn -de' 😎
9. Visit the Live previews and Troubleshooting Wiki pages.

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