# navi icon [![Actions Status](https://github.com/denisidoro/navi/workflows/Tests/badge.svg)](https://github.com/denisidoro/navi/actions) ![GitHub release](https://img.shields.io/github/v/release/denisidoro/navi?include_prereleases) An interactive cheatsheet tool for the command-line. [![Demo](https://asciinema.org/a/406461.svg)](https://asciinema.org/a/406461) **navi** allows you to browse through cheatsheets (that you may write yourself or download from maintainers) and execute commands. Suggested values for arguments are dynamically displayed in a list. #### Pros - it will spare you from knowing CLIs by heart - it will spare you from copy-pasting output from intermediate commands - it will make you type less - it will teach you new one-liners It uses [fzf](https://github.com/junegunn/fzf), [skim](https://github.com/lotabout/skim), or [Alfred](https://www.alfredapp.com/) under the hood and it can be either used as a command or as a shell widget (*à la* Ctrl-R).

Trying out online ----------------- If you don't have access to a Unix shell at the moment and you want to live preview **navi**, head to [this playground](https://www.katacoda.com/denisidoro/scenarios/navi). It'll start a docker container with instructions for you to install and use the tool. Note: login required.
