nnn in action! (click to play video)
`nnn` is probably the [fastest and most resource-sensitive](#memory-usage) file manager you have ever used. It integrates seamlessly with your DE and favourite GUI utilities, has a unique [navigate-as-you-type](#navigate-as-you-type-mode) mode with auto-select, disk usage analyzer mode, bookmarks, contexts, application launcher, familiar navigation shortcuts, subshell spawning and much more. [Integrate utilities](https://github.com/jarun/nnn#sample-scripts) like sxiv or fzy easily, or use it as a [vim file picker](https://github.com/jarun/nnn#neovim-plugin); `nnn` supports as many scripts as you need! It runs on Linux, OS X, Raspberry Pi, Cygwin, Linux subsystem for Windows and Termux. [Quickstart](#quickstart) and see how `nnn` simplifies those long desktop sessions... Missing a feature?

Please use the PAGER-specific keys in these screens. #### 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 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. #### Filters Filters support regexes to instantly (search-as-you-type) list the matching entries in the current directory. Ways to exit filter prompt: - press ^L to clear filter followed by Bksp (to clear the filter symbol, like vi) - at other prompts ^L followed by Enter discards all changes and exits prompt - run a search with no matches and press Enter Common use cases: - to list all matches starting with the filter expression, start the expression with a `^` (caret) symbol - type `\.mkv` to 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 #### File indicators The following indicators are used in the detail view: | Indicator | File Type | |:---:| --- | | `/` | Directory | | `*` | Executable | |
| | Fifo |
| `=` | Socket |
| `@` | Symbolic Link |
| `@/` | Symbolic Link to directory |
| `b` | Block Device |
| `c` | Character Device |
#### File handling
| External dependency | Operation |
| --- | --- |
| xdg-open (Linux), open(1) (OS X), cygstart (Cygwin) | desktop opener |
| file | determine file type |
| cp, mv, rm | copy, move and remove files |
| mediainfo, exiftool | multimedia file details |
| atool, patool ([integration](#integrate-patool)) | create, list and extract archives |
| vidir (from moreutils) | batch rename, move, delete dir entries |
| vlock (Linux), bashlock (OS X), lock(1) (BSD) | terminal locker |
| $EDITOR (overridden by $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):
export NNN_USE_EDITOR=1
#### Help
$ nnn -h
$ man nnn
To lookup keyboard shortcuts at runtime, press ?.
#### QUICKSTART
1. Install the [utilities required](#file-handling) for your regular activities.
2. Configure [cd on quit](#cd-on-quit).
3. Optionally open all text files in EDITOR (fallback vi):
export NNN_USE_EDITOR=1
4. Run `n`.
5. Press ? for help on keyboard shortcuts anytime.
6. For additional functionality [setup custom scripts](#run-custom-scripts).
#### HOW TO
#### add bookmarks
Set environment variable `NNN_BMS` as a string of `key_char:location` pairs (max 10) separated by semicolons (`;`):
export NNN_BMS='d:~/Documents;u:/home/user/Cam Uploads;D:~/Downloads/'
NOTE: Bookmark keys should be single-character to use them in combination with the Leader key.
#### copy file paths
##### 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; 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
To see the path to the temporary copy file, run `nnn`, press ? and look up `copy file`.
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 handle files together:
# bash/zsh
ls -ltr `ncp`
ls -ltr $(ncp)
# fish
ls -ltr (ncp)
##### to clipboard
Along with default copy, `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"
#### 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`](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 `^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.
#### (neo)vim plugin
`nnn` can be used as a file picker/chooser within vim or neovim. Find the plugin [here](https://github.com/mcchrish/nnn.vim).
#### 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 $(find -type f | fzy) >/dev/null 2>&1
#### change dir color
The default color for directories is blue. Option `-c` accepts color codes from 0 to 7 to use a different color:
0-black, 1-red, 2-green, 3-yellow, 4-blue, 5-magenta, 6-cyan, 7-white
Any other value disables colored directories.
#### integrate patool
On systems where `atool` is not available but `patool` is, drop two copies of the Python3 script [natool](https://github.com/jarun/nnn/blob/master/scripts/natool) as `atool` and `apack` somewhere in `$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 locker 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 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
By default in OpenBSD & FreeBSD, `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.
#### Disable file open on navigation
In order to disable opening files on accidental navigation key (→ or l) press:
export DISABLE_FILE_OPEN_ON_NAV=1
To open files with this setting, press Enter.
#### WHY FORK?
`nnn` was initially forked from [noice](http://git.2f30.org/noice/) but is significantly [different](https://github.com/jarun/nnn/wiki/nnn-vs.-noice) today. I chose to fork because:
- one can argue my approach deviates from the goal of the original project - keep the utility `suckless`. `noice` was 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](https://github.com/jarun/nnn/wiki/nnn-design-considerations) for more details.
