#### 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.

`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. **[Quickstart](#quickstart)** and see how `nnn` simplifies workflows.

Visit the **[wiki](https://github.com/jarun/nnn/wiki)** for more.

Here's a video of [`nnn` on Termux (Android)](https://www.youtube.com/watch?v=AbaauM7gUJw).

    $ make
    $ sudo make strip install

`PREFIX` is supported, in case you want to install to a different location.

- Compilation notes for [Raspberry Pi](https://github.com/jarun/nnn/issues/182)
- Instructions for [Cygwin](https://github.com/jarun/nnn/wiki/Cygwin-instructions)

#### Shell completion

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).

| Left single on top row after context numbers | Visit parent |
| Left single/double on last 2 rows | Toggle nav-as-you-type |
| Left single | Select context or entry |
| Left double | Select context or open entry |

##### Leader key

The Leader key provides a powerful multi-functional navigation mechanism. It is case-sensitive and understands contexts, bookmarks and location shortcuts.

| Key | Function |
|:---:| --- |
| <kbd>1-4</kbd> | Go to/create selected context |
| <kbd>></kbd>, <kbd>.</kbd> | Go to next active context |
| <kbd><</kbd>, <kbd>,</kbd> | Go to previous active context |
| key | Go to bookmarked location |
| <kbd>~</kbd> <kbd>`</kbd> <kbd>@</kbd> <kbd>-</kbd> | Go to HOME, `/`, start, last visited dir |
| <kbd>q</kbd> | Quit context |

#### Contexts

Contexts serve the purpose of exploring multiple directories simultaneously. 4 contexts are available. The status of the contexts are shown in the top left corner:

- the current context is in reverse
- other active contexts are underlined
- rest are inactive

To switch to a context press the Leader key followed by the context number (1-4).

The first time a context is entered, it copies the state of the last visited context. Each context remembers its last visited directory.

When a context is quit, the next active context is selected. If the last active context is quit, the program quits.

##### Context-specific color

Each context can have its own directory color specified:

    export NNN_CONTEXT_COLORS='1234'
colors: 0-black, 1-red, 2-green, 3-yellow, 4-blue (default), 5-magenta, 6-cyan, 7-white

#### Dual pane

Any number of `nnn` instances can be opened simultaneously using the lightweight terminal multiplexter [`dvtm`](http://www.brain-dump.org/projects/dvtm/). For example, to open 2 instances or a dual pane mode, have the following alias:

    alias n2="dvtm -m '^h' nnn nnn"

Note that the `dvtm` MOD key is redefined to <kbd>^H</kbd> as the default one (<kbd>^G</kbd>) is also an `nnn` shortcut.

#### Selection

Use <kbd>^K</kbd> to select the file under the cursor.

To select multiple files:

- press <kbd>^Y</kbd> to enter selection mode. In this mode it's possible to
  - cherry-pick individual files one by one by pressing <kbd>^K</kbd> on each entry (works across directories and contexts); or,
  - navigate to another file in the same directory to select a range of files
- press <kbd>^Y</kbd> again to save the selection and exit selection mode.

_NOTE:_ If you are on BSD/macOS, please check the [BSD terminal issue](https://github.com/jarun/nnn#bsd-terminal-issue) with <kbd>^Y</kbd> for workaround.

Selected files are visually indicated by a `+` before the entries.

The selection can now be listed, copied, moved, removed, archived or linked.

Navigate to a target directory then use <kbd>V</kbd> (move) or <kbd>P</kbd> (copy) to have the selected files moved or copied.

Absolute paths of the selected files are copied to the temporary file `.selection` in the config directory. The path is shown in the help and configuration screen. If `$NNN_COPIER` is set the file paths are also copied to the system clipboard.

#### Filters

Filters support regexes (default) to instantly (search-as-you-type) list the matching entries in the current directory.

Common use cases:
- to list all matches starting with the filter expression, start the expression with a `^` (caret) symbol
- type `\.mkv` to list all MKV files
- use `.*` to match any character (_sort of_ fuzzy search)

There is a program option to filter entries by substring match instead of regex.

#### Navigate-as-you-type

In this mode directories are opened in filter mode, allowing continuous navigation. Works best with the **arrow keys**.

When there's a unique match and it's a directory, `nnn` auto selects the directory and enters it in this mode. To disable this behaviour,

    export NNN_NO_AUTOSELECT=1

This mode takes navigation to the next level when short, unique keypress sequences are possible. For example, to reach `nnn` development directory (located at `~/GitHub/nnn`) from my `$HOME` (which is the default directory the terminal starts in), I use the sequence <kbd>g</kbd><kbd>n</kbd>.

The **_wild load_** option can be extremely handy for users who use this mode constantly. The entries are unsorted when the directory loads. Applying filters sorts the entries (with directories on top). Directory color is disabled in this mode.

#### File indicators

The following indicators are used in the detail view:

| Indicator | File Type |
|:---:| --- |
| `/` | Directory |
| `*` | Executable |
| <code>&#124;</code> | Fifo |
| `=` | Socket |
| `@` | Symbolic Link |
| `@/` | Symbolic Link to directory |
| `b` | Block Device |
| `c` | Character Device |
| `?` | Unknown |

#### Hot-plugged drives

External storage devices can be (un)mounted using the plugin [nmount](https://github.com/jarun/nnn/blob/master/plugins/nmount).

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).

#### Help

    $ nnn -h
    $ man nnn
To lookup keyboard shortcuts at runtime, press <kbd>?</kbd>.

#### TROUBLESHOOTING

##### Tmux configuration

`nnn` might not handle keypresses correctly when used with tmux (see issue #104 for more details). Set `TERM=xterm-256color` to address it.

##### BSD terminal issue

TLDR: Use the keybind <kbd>K</kbd> to toggle selection if you are having issues with <kbd>^Y</kbd>.

By default in OpenBSD & FreeBSD (and probably on macOS as well), `stty` maps <kbd>^Y</kbd> to `DSUSP`. This means that typing <kbd>^Y</kbd> will suspend `nnn` as if you typed <kbd>^Z</kbd> (you can bring `nnn` back to the foreground by issuing `fg`) instead of entering multi-selection mode. You can check this with `stty -a`. If it includes the text `dsusp = ^Y`, issuing `stty dsusp undef` will disable this `DSUSP` and let `nnn` receive the <kbd>^Y</kbd> instead.

##### 100% CPU usage

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?

`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.
- I would like to have a bit of control on what features are added in the name of desktop integration. A feature-bloat is the last thing in my mind. Check out the [design considerations](https://github.com/jarun/nnn/wiki/design-considerations) for more details.

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.
