The largest Awesome List of CLI/TUI programs

This repository contains a list of CLI/TUI apps with links and a short description.

To the best of my knowledge, this is the largest collection of CLI/TUI tools available in the form of awesome list.

If you are looking for additional information, you may like CLIpedia, a growing blog about CLI/TUI programs.

Data organization and building of the list

The peculiarity of this repository is that the source of information is structured into CSV files with a simple structure. See the data/ directory.

This README file is generated from the CSV files. To build README.md run:

make

python3 is required for building. And make, of course. :-)

How to contribute

If you have any suggestion or want your project included in the list, you can either open a pull request or send me an email with the necessary information.

If you want to contribute through a pull request, make sure to add new entries to the correct CSV file under the data/ directory. Please commit the CSV file only, not the README. I will review the request and, upon acceptance, I will take care of generating the README and updating the list.
