nnn in action! (click to play video)
`nnn` is probably the [fastest and most resource-sensitive](#performance) (with all its capabilities) file manager you have ever used. It's extremely flexible too - integrates with your DE and favourite GUI utilities, works with the desktop opener, supports bookmarks, has smart navigation shortcuts, [navigate-as-you-type](#navigate-as-you-type-mode) mode, disk usage analyzer mode, comprehensive file details and much more. `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.
If you want to edit a file in vi with some soothing music in the background while referring to a spec in your GUI PDF viewer, `nnn` got it! [Quickstart](#quickstart) and see how `nnn` simplifies those long desktop sessions...
`nnn` supports as many scripts as you want to run! So you can [integrate utilities](https://github.com/jarun/nnn#sample-scripts) like sxiv (to view images in a directory) or fzy (to fuzzy find files in a directory tree) easily.

#### Filters
Filters support regexes to instantly (search-as-you-type) list the matching entries in the current directory.
There are 3 ways to reset a filter:
- pressing ^L (at the new/rename prompt ^L followed by Enter discards all changes and exits prompt)
- a search with no matches
- an extra backspace at the filter prompt (like vi)
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.
#### File indicators
The following indicators are used in the detail view:
| Indicator | File Type |
|:---:| --- |
| `/` | Directory |
| `*` | Executable |
| | | Fifo |
| `=` | Socket |
| `@` | Symbolic Link |
| `@/` | Symbolic Link to directory |
| `b` | Block Device |
| `c` | Character Device |
#### File handling
| External dependency | Operation |
| --- | --- |
| xdg-open (Linux), open(1) (OS X), cygstart (Cygwin) | desktop opener |
| mediainfo, exiftool | multimedia file details |
| gnome-search-tool, catfish | desktop search utility |
| atool, patool ([integration](#integrate-patool)) | create, list and extract archives |
| vidir from moreutils | batch rename, move, delete dir entries |
| vlock (Linux), bashlock (OS X), 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
- To enable the desktop file manager key, set `NNN_DE_FILE_MANAGER`. E.g.:
export NNN_DE_FILE_MANAGER=thunar
export NNN_DE_FILE_MANAGER=nautilus
#### Help
$ nnn -h
$ man nnn
To lookup keyboard shortcuts at runtime, press ?.
### Quickstart
1. Install the [utilities required](#file-handling) for your regular activities.
2. Configure file path copy [using X clipboard](#copy-file-paths-to-clipboard) or [without X](#copy-file-paths-when-x-is-missing).
3. Configure [cd on quit](#cd-on-quit).
4. Optionally open all text files in EDITOR (fallback vi):
export NNN_USE_EDITOR=1
5. Run `n`.
6. Press ? for help on keyboard shortcuts anytime.
7. For additional functionality [setup custom scripts](#run-custom-scripts).
### How to
#### add bookmarks
Set environment variable `NNN_BMS` as a string of `key:location` pairs (max 10) separated by semicolons (`;`):
export NNN_BMS='doc:~/Documents;u:/home/user/Cam Uploads;D:~/Downloads/'
The bookmark prompt also understands the ~ (HOME), - (last visited directory) and & (start directory) shortcuts.
#### use cd .....
To jump to the nth level parent, use `n + 1` dots (the first `.` denotes PWD). For example, to jump to the 6 parent of the current directory, use 7 dots. If the number of dots would take you *beyond* `/` (which isn't possible), you'll be placed at `/`.
#### 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).
As you might notice, `nnn` uses the environment variable `NNN_TMPFILE` to write the last visited directory path. You can change it.
#### copy file paths to clipboard
`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 OS X.
Sample Linux copier script:
#!/bin/sh
# comment the next line to convert newlines to spaces
IFS=
echo -n $1 | xsel --clipboard --input
export `NNN_COPIER`:
export NNN_COPIER="/path/to/copier.sh"
Use ^K to copy the absolute path (from `/`) of the file under the cursor to clipboard.
To copy multiple file paths, switch to the multi-copy mode using ^Y. In this mode you can
- select multiple files one by one by pressing ^K on each entry; or,
- navigate to another file in the same directory to select a range of files.
Pressing ^Y again copies the paths to clipboard and exits the multi-copy mode.
To wrap each file path within single quotes, export `NNN_QUOTE_ON`:
export NNN_QUOTE_ON=1
This is particularly useful if you are planning to copy the whole string to the shell to run a command. Quotes can be toggled at runtime using ^T.
Note that the filename is not escaped. So copying may still fail for filenames having quote(s) in them.
#### copy file paths when X is missing
A very common scenario on headless remote servers connected via SSH. As the clipboard is missing, `nnn` copies the path names to the tmp file `$HOME/.nnncp`.
`nnn` needs to know X is unavailable:
export NNN_NO_X=1
Use ^Y and/or ^K to copy file paths as usual. To use the copied paths from the cmdline, use command substitution:
# 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 -
# bash/zsh
ls -ltr `ncp`
ls -ltr $(ncp)
# fish
ls -ltr (ncp)
Note that you may want to keep quotes disabled in this case.
#### 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 R 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 R. To use the base script (`NNN_SCRIPT`), just press Enter.
##### 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 $(find -type f | fzy) >/dev/null 2>&1
#### dual-pane or multi-pane
`nnn` doesn't have a native dual-pane or multi-pane mode. Use it with tmux, GNU Screen, Terminator or Tilix.
#### change dir color
The default color for directories is blue. Option `-c` accepts color codes from 0 to 7 to use a different color:
0-black, 1-red, 2-green, 3-yellow, 4-blue, 5-magenta, 6-cyan, 7-white
Any other value disables colored directories.
#### file copy, move, delete
`nnn` doesn't support file copy, move, delete natively. However, it simplifies the workflow:
1. copy the absolute paths using ^Y and/or ^K
2. spawn a shell in the current directory (!)
3. while typing the desired command, copy the file paths (usually ^-Shift-V)
In addition, `nnn` integrates with vidir. vidir supports batch file move and delete.
#### integrate patool
On systems where `atool` is not available but `patool` is, drop two copies of the Python3 script [natool](https://github.com/jarun/nnn/blob/master/scripts/natool) as `atool` and `apack` somewhere in `$PATH`.
#### work faster at rename prompt
The rename prompt supports some bash-like command-line shortcuts - ^A, ^E, ^U. ^L clears the name.
#### set idle timeout
The terminal screensaver 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 config
`nnn` might not handle keypresses correctly when used with tmux (see issue #104 for more details). Set `TERM=xterm-256color` to address it.
### Why fork?
I chose to fork because:
- one can argue my approach deviates from the goal of the original project - keep the utility `suckless`. 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.
