An interactive cheatsheet tool for the command-line so that you’ll never say the following again:

How to run that command again?
Oh, it’s not in my bash history
Geez, it’s almost what I wanted but I need to change some args

Demo

naviallows you to browse through cheatsheets (that you may write yourself or download from maintainers) and execute commands, prompting for argument values.

Motivation

The main objectives are:

  • to increase discoverability, by finding commands given keywords or descriptions;
  • to prevent you from running auxiliar commands, copying the result into the clipboard and then pasting into the original command;
  • to easily share one-liners with others so that they don ‘t need to figure out how to write the commands;
  • to improve terminal usage as a whole.

Sure, you can find autocompleters out there for all your favorite commands. However, they are very specific and each one may offer a different learning curve.

Or you can launch a browser and search for instructions on Google, but that takes some time.

navi, on the other hand, intends to be a general purpose platform for bookmarking any command at a very low cost.

Using your own cheatsheets

In this case, you need to pass the directory which contains.cheatfiles as in:

navi --dir"/ folder / with / cheats""

Alternatively, you can set an environment variable in your.Bashrc– like file:

(export) ****************************** (NAVI_DIR=)"/ folder / with / cheats''

Submitting cheatsheets

Feel free to fork this project and open a PR for me to include your contributions.
