# navi <img src="https://raw.githubusercontent.com/denisidoro/navi/master/assets/icon.png" alt="icon" height="28px"/> [](https://github.com/denisidoro/navi/actions) 
|
|
|
|
An interactive cheatsheet tool for the command-line.
|
|
|
|
[](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).
