What Is Head In Git

How To Articles

In my journey as a developer, I have often come across the term “head” in the context of Git. At first, it seemed like a puzzling concept, but as I delved deeper, I realized its significance in version control and its role in managing different states of the repository. Let’s explore what “head” really means in Git and its implications for version control.

Understanding “Head” in Git

At its core, “HEAD” in Git refers to the currently checked out snapshot of the repository. It essentially points to the current branch or commit that you are working on. It acts as a reference to the latest commit in the current branch, serving as the entry point for your work. Understanding “HEAD” is crucial as it dictates which version of the project files you are currently working with.

Impressively, “HEAD” is flexible and can reference different types of objects in Git, including commits, branches, and tags. This versatility allows developers to seamlessly switch between different snapshots of the project, making it easier to work on multiple features or bug fixes simultaneously.

The Two Types of “Head”

In Git, “HEAD” can be categorized into two main types:

  1. Symbolic Ref: When “HEAD” points to a branch, it is referred to as a symbolic ref. This means that any new commits added will cause the branch to move forward, and “HEAD” will automatically update to reflect the latest commit.
  2. Detached HEAD: This scenario occurs when “HEAD” points directly to a commit instead of a branch. It essentially means that any new commits made in this state will not be associated with any branch and can be easily lost if not properly referenced.

Utilizing “Head” in Workflow

When working on a new feature or bug fix, Git allows developers to create a new branch using “HEAD” as the starting point. This feature is incredibly powerful as it enables seamless collaboration and isolation of changes. Additionally, “HEAD” allows for effortless navigation between different snapshots, providing the flexibility needed to manage complex codebases.

Personal Touch

As a developer, I have found “HEAD” to be a fundamental concept in my daily workflow. The ability to switch between branches and commits using “HEAD” has not only streamlined my development process but also empowered me to experiment with different ideas without the fear of disrupting the main codebase. It’s like having a trusty guide that keeps track of my progress and allows me to explore different paths while ensuring I can always find my way back.


In essence, “HEAD” in Git serves as a navigational compass, guiding developers through the vast landscape of version control. Its role in referencing the current state of the repository and facilitating seamless switching between different snapshots is truly invaluable. Understanding “HEAD” not only enhances the efficiency of development but also empowers developers to confidently explore new features and innovations.
