nnn in action! (click to play video)
nnn is probably the fastest and most resource-sensitive file manager you have ever used. It integrates seamlessly with your DE and favourite GUI utilities, has a unique navigate-as-you-type mode with auto-select, disk usage analyzer mode, bookmarks, contexts, application launcher, familiar navigation shortcuts, subshell spawning and much more.
Integrate utilities like sxiv or fzy easily, or use it as a vim file picker; nnn supports as many scripts as you need!
It runs on Linux, OS X, Raspberry Pi, Cygwin, Linux subsystem for Windows and Termux.
Quickstart and see how nnn simplifies those long desktop sessions... Missing a feature? Want to contribute? Head to the rolling ToDo list.

The Leader key (` or ^/) provides a powerful multi-functional navigation mechanism. It is case-sensitive and understands contexts, bookmarks and handy location shortcuts.
| Key | Function |
|---|---|
| 1-4 | Go to selected context |
| >, . | Go to next active context |
| <, , | Go to previous active context |
| key | Go to bookmarked location |
| ~ | Go to HOME directory |
| - | Go to last visited directory |
| & | Go to start directory |
| q | Quit context |
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.
Filters support regexes to instantly (search-as-you-type) list the matching entries in the current directory.
Ways to exit filter prompt:
- press ^L to clear filter followed by Bksp (to clear the filter symbol, like vi)
- at other prompts ^L followed by Enter discards all changes and exits prompt
- run a search with no matches and press Enter
Common use cases:
- to list all matches starting with the filter expression, start the expression with a
^(caret) symbol - type
\.mkvto 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.
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

| mediainfo, exiftool | multimedia file details |
| atool, patool (integration) | 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
$ nnn -h
$ man nnn
To lookup keyboard shortcuts at runtime, press ?.
-
Install the utilities required for your regular activities.
-
Configure cd on quit.
-
Optionally open all text files in EDITOR (fallback vi):
export NNN_USE_EDITOR=1 -

Press ? for help on keyboard shortcuts anytime.
-
For additional functionality setup custom scripts.
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.
Use ^K to copy the absolute path of the file under the cursor.
To copy multiple absolute file paths:
- press ^Y (or Y) to enter selection mode. In this mode it's possible to
- cherry-pick individual 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
- press ^Y (or Y) again to copy the paths and exit the selection mode
The files in the list can now be copied (P), moved (V) or removed (X).
To list the file paths copied to memory press y.
File paths are copied to the temporary file DIR/.nnncp, where DIR (by priority) is:
$HOME or,
$TMPDIR or,
/tmp
To see the path to the temporary copy file, run nnn, press ? and look up copy file.
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)
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 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"
To quit nnn and switch to the directory last opened follow the instructions below.
Pick the appropriate file for your shell from 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.
nnn can be used as a file picker/chooser within vim or neovim. Find the plugin here.
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.
-
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
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.
On systems where atool is not available but patool is, drop two copies of the Python3 script natool as atool and apack somewhere in $PATH.
The rename prompt supports some bash-like command-line shortcuts - ^A, ^E, ^U. ^L clears the name.
The terminal locker is disabled by default. To set the wait time in seconds, use environment variable NNN_IDLE_TIMEOUT.
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.
nnn might not handle keypresses correctly when used with tmux (see issue #104 for more details). Set TERM=xterm-256color to address it.
By default in OpenBSD & FreeBSD, stty maps ^Y to DSUSP. This means that typing ^Y will suspend nnn as if you typed ^Z (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 ^Y instead.
In order to disable opening files on accidental navigation key (→ or l) press:
export DISABLE_FILE_OPEN_ON_NAV=1
To open files with this setting, press Enter.
nnn was initially forked from noice but is significantly different today. I chose to fork because:
- one can argue my approach deviates from the goal of the original project - keep the utility
suckless.noicewas 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 for more details.
