`nnn` is a fork of [noice](http://git.2f30.org/noice/), a blazing-fast lightweight terminal file browser with easy keyboard shortcuts for navigation, opening files and running tasks. noice is developed considering terminal based systems. There is no config file and mime associations are hard-coded. However, the incredible user-friendliness and speed make it a perfect utility on modern distros.
|
||||
|
||||
`nnn` can use the desktop opener at runtime and handle text files or actions with [nlay](https://github.com/jarun/nnn/wiki/all-about-nlay), a customizable bash script. `nnn` adds new navigation options, [navigate-as-you-type](#navigate-as-you-type-mode) mode, enhanced DE integration, a disk usage analyzer mode, comprehensive file details and much more. Add to that a huge [performance](#performance) boost. For a detailed comparison, visit [nnn vs. noice](https://github.com/jarun/nnn/wiki/nnn-vs.-noice).

Filters do not stack on top of each other. They are applied anew every time. There are 4 ways to reset a filter: <kbd>^L</kbd>, an empty filter expression, a search with no results or an extra backspace at the filter prompt (like vi).

`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) is available to you based on your readline [configuration](https://cnswww.cns.cwru.edu/php/chet/readline/readline.html#SEC9).
|

|

#### change text file association
|
||||
|
||||
If `NNN_OPENER` is not set, `nnn` tries to recognize text files by extension and invokes nlay. To add a new extension mainline, please raise a bug. Without it `nnn` will not invoke nlay.
|
||||
|
||||
Text files are opened in vim by default. You can easily change it in nlay.
|
||||
|

nlay has provisions (disabled by default) to handle a specific file extension too. However, the extension should be recognized by `nnn` first.

#### set idle timeout
