Modernizing Command Line Interfaces: A Human-First Design Guide

Command Line Interface Guidelines

We created an open-source guide to help developers build better command-line programs by updating traditional UNIX principles for today. Our focus is on human-first design, ensuring tools are simple, composable, and consistent. We believe the command line remains the most versatile part of computing, offering depth and control that graphical interfaces cannot match, and we want to maximize its utility for everyone.

"Because people don't understand what computing is about, they think they have it in the iPhone, and that illusion is as bad as the illusion that 'Guitar Hero' is the same as a real guitar."
