2. Installing GitHub CLI

Getting started with the GitHub CLI is straightforward. Installation instructions vary slightly depending on your operating system. For Windows users, the easiest method is to download the installer directly from the GitHub CLI releases page. If you’re on macOS, you can use Homebrew with the command brew install gh. Linux users can find installation instructions for various distributions on the official GitHub CLI documentation page.

After installation, you can verify that the CLI is working correctly by typing gh --version in your terminal. You should see the version number of the GitHub CLI you installed. This step ensures that everything is set up correctly before you dive into using it.

3. Authenticating with GitHub

Once installed, the next step in this GitHub CLI tutorial is to authenticate your GitHub account. You can do this easily by running the command gh auth login. The CLI will guide you through the authentication process, where you can choose between HTTPS and SSH methods. For beginners, HTTPS is often simpler.

During the authentication process, you’ll be prompted to open a browser window to log in to your GitHub account. After logging in, you’ll receive a verification code to enter back in the CLI. Once authenticated, your credentials are securely stored, allowing you to interact with your repositories without needing to re-enter your username and password.

4. Basic Commands to Get Started

Now that you’re authenticated, let’s explore some basic commands you can use with the GitHub CLI. One of the most common operations is cloning a repository. You can do this by running gh repo clone . This command pulls the repository from GitHub and creates a local copy on your machine.

Another useful command is gh issue create, which allows you to create a new issue in a repository directly from the command line. You’ll be prompted to enter a title and body for the issue, making it easy to document bugs or feature requests without switching contexts.

It’s also worth mentioning the command gh repo view , which gives you a quick overview of the repository’s details, including the README, recent commits, and any active issues. This can be particularly useful when you’re working on multiple projects and need to switch contexts frequently.

5. Working with Pull Requests

Pull requests (PRs) are a key part of collaborative development, and the GitHub CLI makes managing them a breeze. You can create a new pull request using the command gh pr create. This command will guide you through the process, allowing you to select the base and head branches, and even add a title and description. (See: Learn more about GitHub.)

Additionally, you can view existing pull requests with gh pr list, which shows you a list of open PRs in the current repository. You can also check the status of a specific pull request using gh pr view , making it easy to stay updated on code reviews and feedback.

If you need to merge a pull request, the command gh pr merge allows you to do this directly from the terminal. You can choose between different merging options such as merge, squash, or rebase, giving you flexibility based on your team’s workflow preferences. This command streamlines the merging process and helps maintain your project’s integrity without having to leave the command line.

6. Managing Issues Effectively

Issues are a vital component of any development workflow, and using the GitHub CLI to manage them can enhance your productivity. You can view all issues in your repository with gh issue list. This command displays a list of issues along with labels, state, and assignees, helping you prioritize tasks effectively.

Creating issues is simplified with gh issue create, but you can also close or edit existing issues using commands like gh issue close or gh issue edit . This level of control from the command line can save you time, especially when you need to make quick adjustments.

It’s also beneficial to utilize labels and milestones for better issue management. You can add labels using the command gh issue edit --add-label , which helps categorize issues for easy tracking. Similarly, milestones can be set to group related issues and track progress toward project goals, helping you manage larger projects more effectively.
