- [x] [Next release highlights & ToDo list](https://github.com/jarun/nnn/issues/137)

`nnn` is probably the [fastest and most resource-sensitive](#comparison) file manager you have ever used. It integrates seamlessly with your DE and favourite GUI utilities, has a unique [navigate-as-you-type](#navigate-as-you-type-mode) mode with auto-select, disk usage analyzer mode, bookmarks, contexts, application launcher, familiar navigation shortcuts, subshell spawning and much more.

[Integrate utilities](https://github.com/jarun/nnn#sample-scripts) like sxiv or fzy easily, transfer selected files using lftp or use it as a [(neo)vim plugin](https://github.com/jarun/nnn#neovim-plugin); `nnn` supports as many scripts as you need!

It runs on Linux, macOS, Raspberry Pi, Cygwin, Linux subsystem for Windows and Termux.

[Quickstart](#quickstart) and see how `nnn` simplifies those long desktop sessions.

Help & settings, file details, media info and archive listing are shown in the PAGER. Please use the PAGER-specific keys in these screens.

#### Leader key

The Leader key (<kbd>`</kbd> or <kbd>^/</kbd>) provides a powerful multi-functional navigation mechanism. It is case-sensitive and understands contexts, bookmarks and handy 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> | Go to HOME directory |
| <kbd>-</kbd> | Go to last visited directory |
| <kbd>&</kbd> | Go to start directory |
| <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 used contexts are underlined
- rest are unused

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 start directory and last visited directory.

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

#### Directory color

Each context can have its own color for directories specified:

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

#### Filters

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

Ways to exit filter prompt:
- press <kbd>^L</kbd> to clear filter followed by <kbd>Bksp</kbd> (to clear the filter symbol, like vi)
  - at other prompts <kbd>^L</kbd> followed by <kbd>Enter</kbd> discards all changes and exits prompt
- run a search with no matches and press <kbd>Enter</kbd>

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)

If `nnn` is invoked as root or the environment variable `NNN_SHOW_HIDDEN` is set the default filter will also match hidden files.

#### Navigate-as-you-type mode

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

In case of only one 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

#### 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 |

#### Utility dependencies

| External dependency | Operation |
| --- | --- |
| xdg-open (Linux), open(1) (macOS), cygstart (Cygwin) | desktop opener |
| file | determine file type |
| cp, mv, rm, xargs (from findutils on Linux)  | copy, move and remove files |
| mediainfo, exiftool | multimedia file details |
| atool, patool ([integration](#integrate-patool)) | create, list and extract archives |
| vidir (from moreutils) | batch rename, move, delete dir entries |
| vlock (Linux), bashlock (macOS), lock(1) (BSD) | terminal locker |
| $EDITOR (overridden by $VISUAL, if defined) | edit files (fallback vi) |
| $PAGER | page through files (fallback less) |
| $SHELL | spawn a shell, run script (fallback sh) |

To edit all text files in EDITOR (preferably CLI, fallback vi):

    export NNN_USE_EDITOR=1

Arguments to the `$EDITOR`, `$PAGER` and `$SHELL` should be combined together, e.g.,

    export EDITOR='vim -xR'

The option `open with` takes 1 combined argument and `launcher` takes 2.

#### Help

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

#### QUICKSTART

1. Install the [utilities required](#file-handling) for your regular activities.
2. Configure [cd on quit](#cd-on-quit).
3. Optionally open all text files in EDITOR (fallback vi):

       export NNN_USE_EDITOR=1
4. Run `n`.
5. Press <kbd>?</kbd> for help on keyboard shortcuts anytime.
6. For additional functionality [setup custom scripts](#run-custom-scripts).

#### HOW TO

#### add bookmarks

Set environment variable `NNN_BMS` as a string of `key_char:location` pairs (max 10) separated by semicolons (`;`):

    export NNN_BMS='d:~/Documents;u:/home/user/Cam Uploads;D:~/Downloads/'

NOTE: Bookmark keys should be single-character to use them in combination with the Leader key.

#### copy file paths

##### selection

Use <kbd>^K</kbd> to copy the absolute path of the file under the cursor.

To copy multiple absolute file paths:

- press <kbd>^Y</kbd> (or <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> (or <kbd>Y</kbd>) _again_ to copy the paths and exit the selection mode

The files in the list can now be copied (<kbd>P</kbd>), moved (<kbd>V</kbd>) or removed (<kbd>X</kbd>).

To list the file paths copied to memory press <kbd>y</kbd>.

File paths are copied to the temporary file `DIR/.nnncp`, where `DIR` (by priority) is:

    $HOME or,
    $TMPDIR or,
    /tmp

The path is shown in the help and configuration screen..

To use the copied paths from the cmdline, use command substitution. For example, if `DIR` above is `/home/user`:

    # bash/zsh
    ls -ltr `cat /home/user/.nnncp`
    ls -ltr $(cat /home/user/.nnncp)

    # fish
    ls -ltr (cat /home/user/.nnncp)

An alias may be handy:

    alias ncp='cat /home/user/.nnncp'

so you can easily handle files together:

    # bash/zsh
    ls -ltr `ncp`
    ls -ltr $(ncp)

    # fish
    ls -ltr (ncp)

##### to clipboard

Along with default copy, `nnn` can pipe the absolute path of the current file or multiple files to a copier script. For example, you can use `xsel` on Linux or `pbcopy` on macOS. Here's a sample [copier script](https://github.com/jarun/nnn/tree/master/scripts/copier).

To inform `nnn` of the executable copier script location:

    export NNN_COPIER="/path/to/copier.sh"

##### get selection manually

To get a space-separated list of the file paths in selection, say at the command-prompt:

    cat ~/.nnncp | xargs -0 echo

Set an easy to remember alias:

    alias ncp="cat ~/.nnncp | xargs -0 echo"

To get the list in a file:

    ncp > out.txt

#### cd on quit

To quit `nnn` and switch to the directory last opened follow the instructions below.

Pick the appropriate file for your shell from [`scripts/quitcd`](scripts/quitcd) and add the contents to your shell's rc file. You'll need to spawn a new shell for the change to take effect. You should start `nnn` as `n` (or modify the function name to something else). To change directory on quit press `^G` while exiting.

As you might notice, `nnn` uses the environment variable `NNN_TMPFILE` to write the last visited directory path. You can change it.

#### (neo)vim plugin

`nnn` can be used as a file picker/chooser within vim or neovim. Find the plugin [here](https://github.com/mcchrish/nnn.vim).

#### run custom scripts

`nnn` can invoke custom scripts with the currently selected file name as argument 1.

Export the path to the custom executable script:

    export NNN_SCRIPT=/usr/local/bin/nscript

Press <kbd>R</kbd> to run the script in the current directory.

It's possible to run multiple scripts with `nnn` as long as the scripts are in the same location and share the same prefix. To enable multiple scripts,

    export NNN_MULTISCRIPT=1

With the example of `NNN_SCRIPT` above, some more scripts could be:

    /usr/local/bin/nscript1
    /usr/local/bin/nscript2
    /usr/local/bin/nscriptcustom1
    /usr/local/bin/nscriptcustom2
    and so on...

Type the correct suffix  when prompted on pressing the keybind <kbd>R</kbd>. To use the base script (`NNN_SCRIPT`), just press <kbd>Enter</kbd>.

##### sample scripts

- Open image files in current dir in **sxiv**:

      #!/usr/bin/env sh

      sxiv -q * >/dev/null 2>&1

- Fuzzy find files in **fzy** and open with xdg-open:

      #!/usr/bin/env sh

      xdg-open $(find -type f | fzy) >/dev/null 2>&1

#### change dir color

The default color for directories is blue. Option `-c` accepts color codes from 0 to 7 to use a different color:

    0-black, 1-red, 2-green, 3-yellow, 4-blue, 5-magenta, 6-cyan, 7-white

Any other value disables colored directories.

#### integrate patool

On systems where `atool` is not available but `patool` is, drop two copies of the Python3 script [natool](https://github.com/jarun/nnn/tree/master/scripts/natool) as `atool` and `apack` somewhere in `$PATH`.

#### lftp transfers

lftp can be used from `nnn` for automated remote transfers or copying a selection to a server. Visit the [wiki page](https://github.com/jarun/nnn/wiki/simplify-remote-transfers-with-lftp) for more details on the integration.

#### work faster at rename prompt

The rename prompt supports some bash-like command-line shortcuts - <kbd>^A</kbd>, <kbd>^E</kbd>, <kbd>^U</kbd>. <kbd>^L</kbd> clears the name.

#### set idle timeout

The terminal locker is disabled by default. To set the wait time in seconds, use environment variable `NNN_IDLE_TIMEOUT`.

#### show hot plugged drives

Enable volume management in your DE file manager and set removable drives or media to be auto-mounted when inserted. Then visit the usual mount point location (`/mnt` or `/media/user`) in `nnn`.

#### 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

By default in OpenBSD & FreeBSD, `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-copy 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.

#### Disable file open on navigation

In order to disable opening files on accidental navigation key (<kbd>→</kbd> or <kbd>l</kbd>) press:

    export DISABLE_FILE_OPEN_ON_NAV=1

To open files with this setting, press <kbd>Enter</kbd>.

#### 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 [nnn design considerations](https://github.com/jarun/nnn/wiki/nnn-design-considerations) for more details.
