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 probably the fastest and most lightweight file manager you have ever used; so you don't keep losing precious time every time a sub-optimal file-manager lags.
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 (image preview) or fzy (fuzzy subtree search) 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.
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 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.
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 (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 (works across directories and contexts); 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
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)
To filter entries by substring match:
export NNN_PLAIN_FILTER=1
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
File indicators
The following indicators are used in the detail view:

Utility dependencies
| External dependency | Operation |
|---|---|
| xdg-open (Linux), open(1) (macOS), cygstart (Cygwin) | desktop opener |
| file | determine file type |
| cp, mv, rm, xargs (from findutils on Linux) | copy, move and remove files |

| $EDITOR (overridden by $VISUAL, if defined) | edit files (fallback vi) |
| $PAGER | page through files (fallback less) |

The option open with takes 1 combined argument.

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.
