#### INTRODUCTION
## Introduction
`nnn` is a full-featured file manager for low-end devices and the regular desktop. It's extremely light and fast (**[performance](https://github.com/jarun/nnn/wiki/performance)**).
`nnn` is also a disk usage analyzer, a fuzzy app launcher, a batch file renamer and a file picker. Many **[plugins](https://github.com/jarun/nnn/tree/master/plugins)** are available to extend its power. Custom plugins are easy to add. There's an independent [(neo)vim picker plugin](https://github.com/mcchrish/nnn.vim) project.
It runs on Linux, macOS, Raspberry Pi, BSD, Cygwin, Linux subsystem for Windows and Termux on Android.
It runs on Linux, macOS, Raspberry Pi, BSD, Cygwin, Linux subsystem for Windows and Termux on Android. `nnn` works seamlessly with DEs and GUI utilities. It's nearly zero-config (with sensible defaults) and can be setup in less than 5 minutes.

Option completion scripts for Bash, Fish and Zsh can be found in respective subdirectories of [`misc/auto-completion/`](misc/auto-completion). Please refer to your shell's manual for installation instructions.
#### QUICKSTART
1. Install the [utilities you may need](#utility-dependencies) based on your regular workflows.
2. Configure [cd on quit](https://github.com/jarun/nnn/wiki/hacking-nnn#cd-on-quit).
3. Optionally open all text files in `$EDITOR` (fallback vi): `export NNN_USE_EDITOR=1`
4. For additional functionality [install plugins](https://github.com/jarun/nnn/tree/master/plugins#installing-plugins) and the GUI app launcher [`nlaunch`](https://github.com/jarun/nnn/tree/master/misc/nlaunch).
- Don't memorize keys. Arrows, <kbd>/</kbd> and <kbd>q</kbd> suffice. Press <kbd>?</kbd> for help on keyboard shortcuts anytime.
- When you are ready for more, start [hacking `nnn`](https://github.com/jarun/nnn/wiki/hacking-nnn).
- To set `nnn` as the default file manager, follow these [instructions](https://github.com/jarun/nnn/wiki/nnn-as-default-file-manager).

For auto-mounting external storage drives use udev rules or udisks wrappers.
#### SSHFS mounts
To connect to and mount remote shares using SSHFS, `nnn` requires the ssh configuration file `~/.ssh/config` to have the host entries. sshfs reads this file.
Example host entry for a Termux environment on Android device:
```
Host phone
HostName 192.168.0.102
User u0_a117
Port 8022
```
The above host `phone` will be mounted at `${XDG_CONFIG_HOME:-$HOME/.config}/nnn/phone`. `nnn` creates the directory `phone` if it doesn't exist.
If you need to pass options to the `sshfs` command, you can do so:
export NNN_SSHFS_OPTS='sshfs -o reconnect,idmap=user,cache_timeout=3600'
The options must be preceded by `sshfs` and comma-separated without any space between them.
Notes:
1. `nnn` takes you to the mount point after successful mounts. To jump back to the last directory, press the usual <kbd>-</kbd>.
2. `nnn` doesn't delete the mount point on unmount to prevent accidental data loss. **Please ensure the mount point is not mounted if you are deleting it manually.**
3. More information on [SSHFS](https://wiki.archlinux.org/index.php/SSHFS).

There is a known issue where if you close the terminal directly with `nnn` **_waiting for a spawned process_**, a deadlock occurs and `nnn` uses 100% CPU. Please see issue [#225](https://github.com/jarun/nnn/issues/225) for more details. Make sure you quit the spawned process before closing the terminal. It's not a problem if there is no spawned process (`nnn` isn't blocked) as `nnn` checks if the parent process has exited.
#### WHY FORK?
## Why fork?
`nnn` was initially forked from [noice](http://git.2f30.org/noice/) but is significantly [different](https://github.com/jarun/nnn/wiki/nnn-vs.-noice) today. I chose to fork because:
- one can argue my approach deviates from the goal of the original project - keep the utility `suckless`. `noice` was rudimentary. In my opinion evolution is the taste of time.

Trivia: The name `nnn` is a recursive acronym for the initial words from _Noice is Not Noice, a noicer fork..._, suggested by a longtime friend.
