Hub Command Line Tool: Features and Installation Guide

The Hub command line tool is a Git wrapper that adds GitHub-specific functionality—such as pull request creation, repository forking, and issue management—directly from your terminal.

The tiimgreen/github-cheat-sheet repository documents how Hub extends standard Git workflows with seamless GitHub integration. This guide explains the core features and installation steps to configure this CLI utility according to the official documentation at README.md#L592-L604.

Key Features of the Hub Command Line Tool

Git-Enhanced Commands

As documented in the tiimgreen/github-cheat-sheet source, Hub provides augmented versions of standard Git commands that automatically interact with GitHub's API. Key commands include hub clone, hub fork, hub pull-request, hub issue, and hub compare. These functions perform the same actions as their Git counterparts but add GitHub-specific context and automation.

Automatic Remote Handling

When you execute hub clone, the tool intelligently detects your repository permissions. If you have write access, Hub automatically configures the remote as your personal fork while adding the original repository as an upstream remote. This eliminates manual remote configuration and streamlines the contribution workflow.

Pull Request and Issue Management

The hub pull-request command creates a new pull request from your current branch, pre-populating the title and description using your latest commit message. Similarly, hub issue opens the GitHub issue creation page directly from the command line, allowing you to file bugs or feature requests without switching contexts.

Git Aliases Integration

Hub provides shortcut aliases that map standard Git commands to Hub functionality. For example, git pr translates to hub pull-request. You can enable these aliases by including the Hub alias file in your Git configuration, reducing typing overhead for common GitHub operations.

Installing the Hub Command Line Tool

macOS Installation

Install Hub using Homebrew:

brew install hub

Linux Installation

For Debian and Ubuntu distributions:

sudo apt-get install hub

For Fedora systems:

sudo dnf install hub

Windows Installation

Using the Chocolatey package manager:

choco install hub

Build From Source

Clone the official Hub repository and compile manually:

# Clone the hub source

git clone https://github.com/github/hub.git
cd hub

# Build and install

make install

Configuration and Verification

After installation, verify that Hub is correctly installed:

hub version
hub help

To enable the built-in Git aliases, add the following configuration to your ~/.gitconfig:

[include]
    path = /usr/local/etc/hub.aliases

Once configured, Hub commands function as drop-in replacements for standard Git commands, providing seamless GitHub integration while maintaining full backward compatibility with your existing workflows.

Summary

• Hub is a Git wrapper that adds GitHub-specific features like hub pull-request, hub fork, and hub issue directly from the terminal
• Installation is supported via package managers including Homebrew, apt, dnf, and Chocolatey, or by building from source
• The tool automatically configures remotes when cloning, setting up fork and upstream relationships without manual intervention
• Enable shortcut aliases by including /usr/local/etc/hub.aliases in your .gitconfig to use commands like git pr
• Verify your installation using hub version before integrating into your daily workflow

Frequently Asked Questions

What is the Hub command line tool and how does it differ from Git?

The Hub command line tool is a wrapper that extends Git with GitHub-specific functionality. While Git handles local version control, Hub adds commands to create pull requests, fork repositories, and manage issues by interacting with GitHub's API directly from your terminal.

Can Hub completely replace my existing Git installation?

Yes, Hub is designed as a drop-in replacement for Git. All standard Git commands work identically when prefixed with hub, and you can optionally alias git to hub in your shell configuration to automatically gain the additional GitHub features without changing your workflow habits.

How do I create a pull request using the Hub CLI?

Run hub pull-request from within your feature branch. The command opens a new pull request on GitHub, automatically using your latest commit message as the PR title and description, eliminating the need to manually fill out web forms.

Where is the Hub aliases file located on macOS systems?

According to the tiimgreen/github-cheat-sheet documentation, when installed via Homebrew, the aliases file is located at /usr/local/etc/hub.aliases. You can include this path in your ~/.gitconfig under the [include] section to enable shortcuts like git pr for hub pull-request.
