For example, "main" is a "head" since a branch is a reference to it. It may refer to all of the "heads" in a repository while "head" is written in lowercase. In lowercase, you can see "head" printed. Note: to signify this status, we have used all capital letters. The HEAD is the branch (or a commit) you are now looking at. In my case, it’s pointing to the main branch, so the following output will appear on the shell:Īnd, if you are interested in the commit hash Id on which head is pointing, you can use the following command to display it: You can see where the current Git HEAD is pointing to with the following command: The default used is 1, if no number is mentioned, so HEAD~ is equal to HEAD^. The tilde (~) is a shorthand character for a row of several characters (^).Īnd, in the same way, the equivalence of HEAD~3 to HEAD^^^. The Caret (^) is the parent of the Commit. ![]() More specifically, HEAD is a moving pointer that may or may not refer to the current branch, but it always refers to the current commit. In other words, the HEAD is a pointer to the parent of the next commit or where the next commit will occur since it is where the repo left off. In the repository, HEAD points to the starting point of the current branch at all times. HEAD is a reference to the last commit in the current check-out branch. Whenever you check out a branch or create a new branch, Git HEAD transfers it. In simple terms, you can say Git HEAD is the current branch. When you use the git checkout branch, HEAD points out the last commit. There are many git commands that you can use to manage your branches in git. Git branches are super helpful, and you can create a new branch, merge a branch, or delete a branch, per your requirements. You will learn about the detached head and how you can reset it with a few simple git commands. In this Git HEAD guide, I will explain all about the basics. In case you need a downloadable pdf copy, you can get it here. This will keep the history the same, and it will not change the record of the branch’s history.Recently, I published a detailed guide about Git reset HEAD. You could also make a new commit that signifies exactly the same state of the venture as f414f31.Also, the commits you did after f414f31 will no longer be included in the history of your master branch. Yet, this is rewriting the history of your branch, so if you share your branch with anyone it is best to not use this option. This can be done with git reset –hard f414f31. You could make your current branch to point to the older commit instead.(You can find that via git log or by viewing any history browser.) You then have a few different choices dependent on what you would like to do: ![]() Here is another example, presume that the good commit that you want to go back to is f414f31. HEAD shows your current branch, or current commit, meaning that all git reset –hard HEAD will do is to throw away all of the uncommitted changes you have. Then it will make the files in the working tree and the index (“staging area”) the same as the versions committed in.Make your present branch (typically master) back to point at.When you want to revert to a past commit using git reset – – hard, add. For example, if you do git add to stage a newer version of the file, this will override the past staged version of the file in the staging area. But be sure to note that Git does not take track of changes to your files. When you have created a commit, which will have your project files stored in a particular state, they ae safe. Git records the state of the files when you stage them with git add or when you make a commit. Be sure to always double check that the output of git status is empty (clean) before you begin using it. Luckily there is an easy solution to follow to correct this.įirst of all git reset - hard is a very dangerous command because it eliminates all of your noncommitted changes. A question that comes up with developers is how to use git reset– hard HEAD to revert to previous commit.
