Rebase is a Git utility that serves for integrating changes from one branch to another. Along with <\/span>git merge<\/span><\/i>, it is the only change integration utility. While <\/span>git merge<\/span><\/i> is a forward-moving process, <\/span>rebase <\/span><\/i>provides powerful history rewriting features. In a way, we can understand <\/span>rebase <\/span><\/i>as a merge with Git history.<\/span><\/p>\n

That being said, it may happen that you accidentally performed the <\/span>git rebase<\/span><\/i> command on a local branch and pushed the changes to remote. So, which steps should you take to undo this action and resolve the problem? In today\u2019s article, our <\/span>web development agency in Chicago<\/span><\/a> explores ways to undo rebase in Git. We\u2019ll also talk about common rebase use cases and caveats, as well as provide a detailed look at <\/span>git rebase<\/span><\/i> configuration and execution.<\/span><\/p>\n

What is rebasing in Git?<\/h2>\n

Rebase is the process that allows you to move or combine a sequence of commits to a new base commit. In the context of a feature branching workflow, you can visualize the process, as shown in the figure below.<\/span>
\n<\/span><\/p>\n\"\"\n

If we view this operation from a content perspective, we can say that rebasing is the action of changing the base of a branch from one commit to another. Developers use rebase to change the starting point of a branch in commit history to the final commit of the main or any other branch. In layman’s terms, rebase allows you to move the starting point of your branch to another point.<\/span><\/p>\n

Though, at first glance, it may seem that your branch looks the same, it is essential to note that it is actually made of entirely new commits applied to the specific base.<\/span><\/p>\n

Use cases<\/h3>\n

Git rebase is most commonly used to maintain a linear history of your project. Let\u2019s say that the master branch of your project has further progressed while you were working on your feature branch. Now, you wish to get those master branch updates to your feature branch and keep your branch\u2019s history clean, so you can later seamlessly merge it back into the master branch. By doing rebase, you\u2019ll get the same outcome as if you were working off the latest master branch.<\/span><\/p>\n

To better understand the benefits of keeping a clean branch history, imagine the following situation:<\/span><\/p>\n

A bug appeared on the master branch that prevented a particular feature from functioning as intended. You use the <\/span>git log<\/span><\/i> to check the history of the master branch. Since you and your team followed the practice of keeping a clean history, you\u2019ll have no problems understanding the data. If you cannot identify when the bug was introduced with the <\/span>git log<\/span><\/i> command, you\u2019ll likely execute <\/span>git bisect<\/span><\/i>. Due to the clean history, <\/span>git bisect<\/span><\/i> can work with a refined set of commits and compare them to find the one that introduced the bug, giving you the chance to act accordingly and promptly.<\/span><\/p>\n

There are two ways to integrate your feature branch into the master branch:<\/span><\/p>\n
