GitHub Copilot CLI 101: How to use GitHub Copilot from the command line

You don’t have to leave your terminal to use GitHub Copilot anymore. 

With GitHub Copilot CLI, you can ask questions, generate scripts, refactor code, and run commands—all without breaking your flow.  

In this blog, we’ll explore exactly what GitHub Copilot CLI is, how it works, the best ways to use it, and how you can start working with Copilot right from your terminal.

What is GitHub Copilot CLI?

A command-line interface (CLI) is where you can type commands directly into a terminal or console to interact with software and systems. It’s how you often run scripts, automate workflows, and access APIs.

The GitHub Copilot CLI brings Copilot’s AI capabilities right into that environment. Instead of jumping between your IDE and browser, you can ask Copilot to generate, explain, or execute commands. In short, Copilot CLI gives you more precision and control over how you work. 

For instance, you can ask:

copilot "create a bash script to check for uncommitted changes and push if clean"

The Copilot CLI will write the script, explain what it does, and ask you to confirm before running it.

Whether you’re debugging code, managing environments, navigating a legacy codebase, or handling complex implementations, Copilot CLI helps you work faster without leaving your local environment—saving you time and effort.

How does GitHub Copilot CLI work?

CLIs follow a simple loop: you type a command, the system runs it, and you get a result.

GitHub Copilot CLI builds on that workflow but adds an AI-powered twist. Instead of just running predefined commands, you can talk to your terminal in natural language. You tell Copilot CLI what to do, and it figures out the commands to make it happen. (Copilot CLI also supports a number of slash commands and integrations with MCP to extend its capabilities.)

You can use Copilot CLI in two ways:

• Interactive mode (the default mode) lets you start a session with the copilot command and have a back-and-forth conversation, refining tasks as you go. 
• Programmatic mode is for one-off prompts: pass a request directly with -p or –prompt, and Copilot responds inline. For tasks that involve modifying or executing files, you can enable approval options to keep things safe and consistent. 

No matter how you use it, Copilot CLI will always ask for confirmation before reading, modifying, or executing files. That means you stay in control of your environment. (Note: One exception is if you choose “Yes, and remember this folder for future sessions” or “Yes, and approve TOOL for the rest of the session” when prompted—Copilot will follow these instructions instead. More details in our starter kit below!)

Starter kit: How to install and use GitHub Copilot CLI

Using GitHub Copilot CLI is easier than you think. We created a starter kit for you that explains how to install GitHub Copilot CLI, a step-by-step tutorial on how to use the tool, and common use cases and prompts you can use with Copilot in your terminal. Let’s dive in. 

Step one: Installing GitHub Copilot CLI

To get started with GitHub Copilot CLI, you need:

• A GitHub Copilot subscription: Copilot CLI is currently available with the GitHub Copilot Pro, GitHub Copilot Pro+, GitHub Copilot Business, and GitHub Copilot Enterprise plans. 
• Node.js version 22 or later
• npm version 10 or later

[Note: If you get Copilot access from an organization, the Copilot CLI policy must be enabled in your organization’s settings.]

Install Copilot CLI with the following command:

npm install -g @github/copilot

That’s it. Now you’re ready to get started. ✨

Step two: How to use GitHub Copilot CLI

It’s time to start using Copilot in the command line (we have step-by-step instructions on how to do this in our docs).

1.  In your terminal, choose the folder with the code you’re working on.
2.  Type copilot into the chat box to begin using Copilot CLI. You’ll be prompted to confirm that you trust the contents of the folder. 

1.  You can select one of these options:

• Yes, proceed: Copilot can access and use the files in this location for only this session.
• Yes, and remember this folder for future sessions: The files in this folder are trusted for current and future sessions. When starting Copilot CLI from this folder, you won’t be asked this question again (so only select this option if you are sure that it will always be safe for Copilot to work with these files).
• No, exit (Esc): End your Copilot CLI session.

2. If you are not currently logged in to GitHub, you’ll be prompted to use the /login slash command. Enter this command and follow the on-screen instructions to authenticate.

Enter your prompt in the CLI (we’ll explore some examples of great prompts in the next section!)

Step three: GitHub Copilot CLI use cases, plus example prompts and workflows

In this section, we’re providing tons of use cases along with sample prompts that you can feed Copilot to achieve similar outcomes.

GitHub Learn: GitHub Copilot CLI

In this video tutorial, @arilivigni, senior learning advocate and cloud solutions architect at GitHub, demonstrates some foundational ways to use GitHub Copilot CLI to create GitHub issues, pull requests, and more. 

Here are some of the GitHub Copilot CLI prompts that were highlighted in the video:

Create a GitHub Issue: Log actionable tasks that keep progress visible.

Create an issue for adding GitHub Copilot instructions

Create Copilot custom instructions: Give Copilot more context on your project so it can deliver even better AI assistance that fits your workflows.

Create a branch for GitHub Copilot custom instructions

Create a pull request: Propose changes that enhance code quality.

Create a pull request with the changes we have made

Attach this pull request to issue #4

Show the content of issue #4

What pull requests are attached to this issue?

Use the MCP server to list all open issues and pull requests

Use MCP servers to query Microsoft Learn: Access official Microsoft Learn content directly from the CLI for quick answers and guidance.

Using the Microsoft Learn MCP server, tell me all the GitHub Copilot Microsoft Learn modules that exist

What are the names of the hands-on Skills exercises that exist in each module? 

Create a README with all the Microsoft Learn GitHub Copilot modules and the hands-on skills with headings and subheadings

Create an alias to use with the CLI: Reduce repetitive effort with shortcuts that boost speed and efficiency.

alias grep copilot

cpcli='copilot --allow-all-tools -p "$@"'

Explain and fix scripts: Diagnose script errors and apply fixes to keep your code running smoothly.

cpcli "Explain each of these scripts and offer improvements" 

Other ways to use GitHub Copilot CLI

Here are some common use cases for GitHub Copilot CLI, along with specific prompts you can feed Copilot.

Codebase maintenance: Handle security patches, upgrade dependencies, and perform focused refactoring to keep your codebase healthy.

• Request a script for scanning and fixing security vulnerabilities
