nnn
Noice is Not Noice, a noicer fork...
nnn in action! (Thanks Luke Smith for the video!)
nnn is smooth... like butter. It's also one of the fastest and most lightweight file managers you have ever used. It comes in a ~50KB binary using ~3.5MB resident memory at runtime.
nnn 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, quick notes and much more.
Integrate utilities like sxiv (view images in directory) or fzy (fuzzy search subtree) easily, transfer selected files using lftp or use it as a (neo)vim plugin; nnn supports as many scripts as you need! Refer to the How to section on wiki for more details.
It runs on Linux, macOS, Raspberry Pi, BSD, Cygwin, Linux subsystem for Windows and Termux on Android.
Quickstart and see how nnn simplifies those long desktop sessions.

Leader key
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/create 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
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 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 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
Selection
Use ^K to copy the absolute path of the file under the cursor.
To copy multiple absolute file paths:
- press ^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 (works across directories and contexts); or,
- navigate to another file in the same directory to select a range of files
- press ^Y again to save the selection and exit selection mode.
Selected files are visually indicated by a +.
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
The path is shown in the help and configuration screen.
Filters
Filters support regexes by 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
\.mkvto 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.
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
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
The wild mode program option can be handy for users who use this mode constantly. The entries are unsorted when the directory loads. Applying filters sort 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 |
| |
Fifo |
= |
Socket |
@ |

QUICKSTART
-
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 -
Run
n. -
Don't memorize keys. Arrows, / and q suffice. Press ? for help on keyboard shortcuts anytime.
-
The prompt can be used as a launcher and to run commands.
- For additional functionality setup custom scripts.
- Visit the How to for many more specific usecases.
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 K to toggle selection if you are having issues with ^Y.
By default in OpenBSD & FreeBSD (and probably on macOS as well), 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.
Restrict file open
In order to disable opening files on accidental navigation key (→ or l) press:
export NNN_RESTRICT_NAV_OPEN=1
Use Enter to open files.
Restrict 0-byte files
Restrict opening 0-byte files due to unexpected behaviour; use edit or open with to open the file.
export NNN_RESTRICT_0B=1
WHY FORK?
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.
