A Git repository is composed of different objects and references. If you were to, for example, run the git checkout HEAD~3 command, then the HEAD would move/point to the commit with the id " 76af06471c3a5281ff7fe38ce9". This is the default behavior of git checkout when is not a branch name. The term HEAD in Git refers to the latest commit of your currently checked-out branch.3 commits older than HEAD)įor a more practical example, let's consider the following git commit history: Another use case for 'checkout' is when you want to restore a historic version of a specific file. The most common use case for 'checkout' is when you want to switch to a different branch, making it the new HEAD branch. If you were to switch branches with git checkout then the HEAD will change to the last commit on the branch. HEAD: It is just your current branch last commit snapshot. In the example above, since HEAD is pointing to " X", the following would be true: git checkout The 'checkout' command can switch the currently active branch - but it can also be used to restore files. Its important to be aware: checking out a Git commit or a Git tag will move the HEAD point to a commit instead of a branch. It refers to your local directory and git status will give you the state of your working directory. To understand this better, consider for example, the following visualization: HEAD~3 # refers to first parent of the "grandparent" HEAD~2 # refers to first parent of the first parent (or the "grandparent") Letâs have a look at the changes using the git status command. ![]() It rollbacks any content changes to those of the specific commit. HEAD~1 # refers to the first parent of the commit object In order to move the HEAD to one commit before, use the git reset command with the soft option and specify HEAD git reset -soft HEAD (or HEAD1) This time, the staging area will be filled with the changes done between the commit 7a9ad7f and the commit 802a2ab. Checkout: Use this to move the HEAD pointer to a specific commit or switch between branches. FATAL: Could not checkout null with start. In git, ~N suffix added to HEAD points to the " N"-th ancestor commit relative to HEAD (or more specifically, from the first parent of the commit object that HEAD points to) in the current branch: Command git read-tree -mu HEAD returned status code 128: stdout: stderr: fatal: Not a valid object name HEAD. ![]()
