Another situation that causes a detached HEAD is checking out the remote branch. We already demonstrated that if you check out the SHA-1 commit hash, you will be in the detached HEAD state.

Checking out to a remote branch without fetching it first.

Checking out a specific Secure Hash Algorithm 1 (SHA-1) commit hash.

You can find yourself in a detached HEAD state primarily through two scenarios: Scenarios that can cause a detached HEAD state In this case, HEAD does not point to any branch-it references a commit. Continuing from the previous scenario, if you check out to the first commit on the main branch, you will see that HEAD is now detached. In Git, you can also check out a particular commit, which results in the detached HEAD state. In both of the diagrams above, HEAD points to the most recent commit in the currently checked out branch, which is its normal state.

You can create this scenario with the following Git commands: git branch feature Since you are checked out to the feature branch, HEAD points there. In this situation, you have two branches, the main branch and a feature branch. HEAD is also a common state when working with multiple branches. In this image, the HEAD points to the latest commit and current checked-out branch on every commit in the current branch. However, in a detached HEAD state, the HEAD does not point to any branch, but a specific commit or the remote repository.īelow is a diagram of the Git HEAD in a normal state, pointing to the latest commit in the main branch. In Git, HEAD refers to the currently checked-out branch’s latest commit.

Then, we will demonstrate how to save or discard changes in a detached head so you can quickly recover from the situation. In this article, we will explore what the Git detached HEAD state is and some situations that cause it.

Complex commands and a less intuitive user interface can sometimes lead to unwanted states, including a state called detached HEAD. However, learning Git is more complicated than learning SVN or CVS. It is fast, scalable, and has more commands and flexibility than older version control tools like Apache Subversion (SVN) and Concurrent Versions System (CVS).

It makes collaboration easier by allowing branching to keep code for different features separate and seamlessly merging commits by various people. Git allows developers to maintain a history of changes, or commits, to their code and revert to previous commits in seconds if something goes wrong.

The introduction of Git as a source-code management system in 2005 fundamentally transformed the process of software development.
