nnn
Noice is Not Noice, a noicer fork...
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, familiar navigation shortcuts, subshell spawning and much more.
Integrate utilities like sxiv or fzy easily; nnn supports as many scripts as you need!
Quickstart and see how nnn simplifies those long desktop sessions...

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
\.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.
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. To disable this behaviour,
export NNN_NO_AUTOSELECT=1

Run
n. -
Press ? for help on keyboard shortcuts anytime.

For additional functionality setup 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.
copy file paths
File paths can be copied to the clipboard or to a specific temporary file (if X is unavailable, for example). When in multi-copy mode, currently copied file paths can be listed by pressing y.
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.
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 DIR/.nnncp, where DIR (by priority) is:
$HOME or,
$TMPDIR or,
/tmp
nnn needs to know X is unavailable:
export NNN_NO_X=1
To see the path to the copy file, run nnn, press ? and look up NNN_NO_X.
Note: despite the name of the environment variable, this method works even if X is available.
Use ^Y and/or ^K to copy file paths as usual. 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 copy, move or delete multiple files together:
# bash/zsh
ls -ltr `ncp`
ls -ltr $(ncp)
cp -rvf `ncp` .
mv `ncp` .
rm `ncp` -rf
# fish
ls -ltr (ncp)
cp -rvf (ncp) .
mv (ncp) .
rm (ncp) -rf
Note that you may want to keep quotes disabled in this case.
copy, move, delete files
The nnn workflow to copy, move or delete files is:
- Copy the absolute paths using ^Y and/or ^K
- To copy or move files navigate to the destination directory. You can also fire a new instance of
nnnin another tab of your terminal emulator and open the destination directory. - Spawn a subshell in the destination directory (!)
- While typing the desired command, copy the file paths (usually ^-Shift-V) from the clipboard. If X is unavailable, refer to this section.
In addition, nnn integrates with vidir. vidir supports batch file move and delete.
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 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 Q (it's capital) or ^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.
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.
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 /.
integrate patool
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.
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?
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. 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.
