![]() ![]() 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. So, if you have checked out a past specific commit, then please don’t make any changes to your repo unless you create a new branch for them or you switch back to the latest commit HEAD.The introduction of Git as a source-code management system in 2005 fundamentally transformed the process of software development. That is why, git automatically gives you two options shown above – either create a new branch for future changes, or revert back to the original HEAD and then make changes. $ git switch -īut please note, if you checkout a past commit, then your HEAD pointer will become detached, that is, all future changes will not belong to any branch unless you create a new one to record future changes. Or you can run the following command, to switch back to the latest HEAD (that is the latest commit before checkout). Now the above commit will be checked out for you and its changes will be the latest changes for you.Īt this point, you can choose to create a new branch for future commits, using the following command. If you want to checkout a previous commit with ID, run the git checkout command followed by that commit’s ID. These identifiers are generated and stored by git command.Īs you can see in the previous step, the latest commit has an ID 7d6a76ad9c370ccacabca27d765a8a13ddad36a5. The above output lists 3-4 most recent commits, each having a commit ID, author, datetime and the commit message.Ĭommit history is a history of all the commits made to your git repository, starting from initial commit all the way to the latest one.Įach commit in git history has an SHA1 identifier that is used to uniquely identify the commit. Next, run the following command to view the commit history of your git repository. Next, navigate to the repository folder using cd command. You can also clone your git repository from other sites like BitBucket. Else you can clone your git repository from a remote URL. If you already have a working git repository on your system, you can skip this step. Here are the steps to checkout specific commit in git. In this article, we will learn how to checkout specific commit in Git. In other words, you may want to switch to a specific commit. Sometimes you may need to checkout a specific commit. These commits allow you to view the changes made in a specific snapshot and even revert to a specific commit. It keeps track of changes to source code in the form of snapshots, known as commits. Git is a popular distributed version control system used by many developers and organizations around the world.
