A beginner-friendly guide to using command-line interfaces (CLIs) for business professionals who want to unlock the power of AI coding assistants.
Windows PC user? Head to the PC version instead.
You're a business professional—maybe you work in operations, finance, marketing, HR, or management. You've probably used Claude through the website (claude.ai) or the desktop app. That's great for conversations, but there's a more powerful way to work with AI.
Claude Code runs in your terminal (command line) and can actually read, write, and edit files on your computer. It's the difference between talking about work and doing work.
This guide will take you from zero to productive, even if you've never opened a terminal in your life.
| Desktop Claude | Claude Code (CLI) |
|---|---|
| Chat conversations | Chat + file access |
| Copy/paste text manually | Read files directly from your computer |
| Describe what you want | Actually create and edit files |
| Talk about code | Run code and commands |
| Limited context | Full access to your projects |
The bottom line: Claude Code can do things the desktop app simply cannot. It's like the difference between describing a recipe and having a chef cook it for you.
