### Introduction
|
||||
|
||||
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 default desktop opener at runtime and handle media types with `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 support regexes to display only the matched entries in the current directory view. This effectively allows searching through the directory tree for a particular entry. Matching entries are shown instantly (search-as-you-type).

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