nnn (type less, do more)
nnn in action (Thanks Luke Smith for the video!)
nnn is 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 works seamlessly with your DE and favourite GUI utilities. It runs on Linux, macOS, Raspberry Pi, BSD, Cygwin, Linux subsystem for Windows and Termux on Android.
Have as many scripts as you want to extend the power of
nnn! Pick from the scripts repository or add your own.

Help & settings, file details, media info and archive listing are shown in the PAGER. Use the PAGER-specific keys in these screens.
The Leader key provides a powerful multi-functional navigation mechanism. It is case-sensitive and understands contexts, bookmarks and location shortcuts.
|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|
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.
Each context can have its own directory color specified:
colors: 0-black, 1-red, 2-green, 3-yellow, 4-blue (default), 5-magenta, 6-cyan, 7-white
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.
NOTE: If you are on BSD/macOS, please check the BSD terminal issue with ^Y for workaround.
Selected files are visually indicated by a
The selection can now be listed, copied, moved, removed, archived or linked.
File paths are copied to the temporary file
DIR (by priority) is:
$HOME or, /tmp $TMPDIR or,
The path is shown in the help and configuration screen.
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
\.mkvto list all MKV files
.*to match any character (sort of fuzzy search)
There is a program option to filter entries by substring match instead of regex.
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,
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 gn.
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.
The following indicators are used in the detail view:
||Symbolic Link to directory|
nnn supports the following environment variables for configuration.
||specify bookmarks (max 10)|
||custom file opener|
||do not block when invoking file opener|
||specify per context color [default: '4444' (all blue)]|
||idle seconds before locking terminal [default: disabled]|
||system clipboard copier script [default: none]|
||path to script dir or a single script|
||path to note file [default: none]|
||file to write current open dir path to for cd on quit|
||Open text files in
||do not auto-select matching dir in nav-as-you-type mode|
||open files on ↵, not → or l|
||do not open 0-byte files|
||trash files to the desktop Trash [default: delete]|
||show copy, move progress on Linux|
$ nnn -h $ man nnn
To lookup keyboard shortcuts at runtime, press ?.
nnn can invoke custom scripts in the current directory (
$PWD for the script) with the currently selected file name as the argument.
Copy the scripts of your interest in the user-scripts directory and let
nnn know the location:
Use the run/pick script shortcut to jump to the script directory and pick a script. Repeating the same shortcut cancels the operation and puts you back in the original directory.
In case you need only one script:
If you have an interesting script feel free to raise a PR.
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:
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.
- one can argue my approach deviates from the goal of the original project - keep the utility
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.
Trivia: The name
nnn stands for Noice is Not Noice, a noicer fork....
