Noice is Not Noice, a noicer fork...
nnn in action! (click to play video)
nnn is probably the fastest and most resource-sensitive (with all its capabilities) file browser 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 mode, disk usage analyzer mode, comprehensive file details and much more.
nnn was initially forked from noice but is significantly different 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 and see how
nnn simplifies those long desktop sessions...
nnn supports as many scripts as you want to run! So you can integrate utilities like sxiv (to view images in a directory) or fzy (to fuzzy find files in a directory tree) easily.
Have fun with it! Missing a feature? Want to contribute? Head to the rolling ToDo list.

Help & settings, file details, media info and archive listing are shown in the PAGER. Please use the PAGER-specific keys in these screens.
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
\.mkvto list all MKV files
.*to match any character (sort of fuzzy search)
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.
The following indicators are used in the detail view:
|xdg-open (Linux), open(1) (OS X)||desktop opener|
|mediainfo, exiftool||multimedia file details|
|gnome-search-tool, catfish||desktop search utility|
|atool||create, list and extract archives|
|vidir from moreutils||batch rename, move, delete dir entries|
|vlock (Linux)||terminal locker|
|$EDITOR ($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):
To enable the desktop file manager key, set
export NNN_DE_FILE_MANAGER=thunar export NNN_DE_FILE_MANAGER=nautilus
$ nnn -h $ man nnn
To lookup keyboard shortcuts at runtime, press ?.
Add the following to your shell's rc file for the best experience:
Use a shorter and sweeter alias:
Optionally open all text files in EDITOR (fallback vi):
Set a desktop file manager to open directories with (if you ever need to). E.g.:
Press ? for help on keyboard shortcuts anytime.
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
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
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
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
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.
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
nnn needs to know X is unavailable:
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 /tmp/nnncpuser` ls -ltr $(cat /tmp/nnncpuser) # fish ls -ltr (cat /tmp/nnncpuser)
An alias may be handy:
alias ncp='cat /tmp/nnncpuser'
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:
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,
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
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:
- copy the absolute paths using ^Y and/or ^K
- spawn a shell in the current directory (!)
- while typing the desired command, copy the file paths (usually ^-Shift-V)
nnn integrates with vidir. vidir supports batch file move and delete.
boost chdir prompt
nnn uses libreadline for the chdir prompt input. So all the fantastic features of readline (e.g. case insensitive tab completion, history, reverse-i-search) are available to you based on your readline configuration.
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
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 (
nnn might not handle keypresses correctly when used with tmux (see issue #104 for more details). Set
TERM=xterm-256color to address it.
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 for more details.
