GitHub CLI gh Complete Command Line Guide 2026

GitHub CLI, often referred to as gh, is a powerful command-line tool that allows developers to interact with GitHub repositories directly from the terminal. For Pakistani students learning programming and software development, mastering GitHub CLI 2026 is an essential skill. Whether you’re submitting pull requests for your Lahore-based open-source project, managing issues for a Karachi startup, or automating workflows in Islamabad, gh simplifies workflows, improves productivity, and makes collaboration easier.

Unlike the web interface, the CLI allows faster navigation, scripting, and automation of tasks like pull requests, issues, releases, and more—all without leaving the terminal.

Prerequisites

Before diving into GitHub CLI, make sure you have the following:

• Basic knowledge of Git and GitHub
• Familiarity with the command line (Terminal in macOS/Linux, PowerShell/Command Prompt in Windows)
• Git installed on your machine
• A GitHub account (signup here)
• Optional: Basic knowledge of shell scripting for automation tasks

Pakistani students working on university projects at NUST, FAST, or COMSATS will find that gh complements Git knowledge with practical efficiency in collaborative coding projects.

Core Concepts & Explanation

Understanding GitHub CLI Authentication

Before using gh, you must authenticate it with your GitHub account. This allows the CLI to perform actions such as creating pull requests, issues, or viewing repositories.

gh auth login

Explanation:

gh auth login       # Starts the authentication process

• Choose GitHub.com
• Select HTTPS or SSH (HTTPS is recommended for beginners)
• Complete authentication via web browser or token

This ensures all commands you run are authorized with your GitHub account.

Navigating Repositories with gh

You can view, clone, and manage repositories entirely via CLI.

gh repo clone iqra-edu/learning-project

Line-by-line explanation:

gh repo clone       # Clone a repository from GitHub
iqra-edu/learning-project  # Repository owner and repository name

• Ahmad in Lahore can clone his university project repo directly without opening GitHub.com
• You can list repositories with gh repo list iqra-edu

Pull Requests (PRs) Management

Creating, viewing, and merging PRs becomes simple:

gh pr create --fill --base main --head feature/login

Explanation:

gh pr create       # Command to create a pull request
--fill             # Auto-fills title and description from the branch
--base main        # Target branch to merge into
--head feature/login # Branch containing your changes

• Fatima in Karachi can now open a PR for her login feature without leaving the terminal

Issues Management

Track and create issues directly:

gh issue create --title "Fix login bug" --body "Error occurs when password is empty"

Explanation:

gh issue create     # Command to create a new issue
--title             # Title of the issue
--body              # Description of the problem

• Ali in Islamabad can report bugs in group projects efficiently
• View open issues using gh issue list

Workflows & Automation

GitHub Actions workflows can also be triggered from the CLI:

gh workflow run build.yml

Explanation:

gh workflow run   # Command to trigger a workflow
build.yml         # Name of the workflow file

• This allows students to automate CI/CD pipelines for testing, building, or deploying projects

Practical Code Examples

Example 1: Creating a Pull Request

# Step 1: Checkout to feature branch
git checkout -b feature/signup

# Step 2: Make changes and commit
git add .
git commit -m "Add signup feature"

# Step 3: Push branch to GitHub
git push origin feature/signup

# Step 4: Create pull request
gh pr create --fill --base main --head feature/signup

Line-by-line explanation:

• git checkout -b feature/signup → Creates and switches to a new branch for your signup feature
• git add . → Stages all changes
• git commit -m "Add signup feature" → Commits changes with a message
• git push origin feature/signup → Pushes branch to GitHub
• gh pr create --fill --base main --head feature/signup → Opens a PR automatically

Example 2: Real-World Application — Automating Issue Tracking

# Create issue
gh issue create --title "Update README for lab project" --body "Add steps for setting up environment"

# Assign to a collaborator
gh issue edit 1 --assignee Ahmad

Line-by-line explanation:

• gh issue create → Adds a new issue for project documentation
• gh issue edit 1 --assignee Ahmad → Assigns issue #1 to Ahmad for completion
• Ideal for group projects in Lahore or Karachi universities

Common Mistakes & How to Avoid Them

Mistake 1: Not Authenticating gh

Problem: Commands fail due to lack of authentication.

Solution: Always run:

gh auth login

Mistake 2: Wrong Branch Reference in PR

Problem: Creating a PR with incorrect --base or --head.

Solution: Verify branches first:

git branch
gh pr create --fill --base main --head feature/correct-branch

Practice Exercises

Exercise 1: Create Your First PR

Problem: Clone a repository, create a new branch, and open a PR.

Solution:

gh repo clone iqra-edu/student-project
git checkout -b feature/test
git add .
git commit -m "Initial test commit"
git push origin feature/test
gh pr create --fill --base main --head feature/test

Exercise 2: Assign Issues to Team Members

Problem: Create an issue and assign it to Fatima.

Solution:

gh issue create --title "Fix navigation bug" --body "Navbar overlaps content"
gh issue edit 1 --assignee Fatima
