![]() Execute git fetch to pull the latest remote commits. Make sure the receiving branch and the merging branch are up-to-date with the latest remote changes. In our case we will execute git checkout main. If needed, execute git checkout to switch to the receiving branch. Confirm the receiving branchĮxecute git status to ensure that HEAD is pointing to the correct merge-receiving branch. Preparing to mergeīefore performing a merge there are a couple of preparation steps to take to ensure the merge goes smoothly. This scenario is a version control conflict and Git will need user intervention to continue. If Git encounters a piece of data that is changed in both histories it will be unable to automatically combine them. When creating a merge commit Git will attempt to auto magically merge the separate histories for you. Merge commits are unique against other commits in the fact that they have two parent commits. Git will determine the merge algorithm automatically (discussed below). Invoking this command will merge the specified branch feature into the current branch, we'll assume main. We now want to merge this feature branch into main. ![]() Say we have a new branch feature that is based off the main branch. Once Git finds a common base commit it will create a new "merge commit" that combines the changes of each queued merge commit sequence. The following examples in this document will focus on this branch merging pattern. In these scenarios, git merge takes two commit pointers, usually the branch tips, and will find a common base commit between them. Git merge will combine multiple sequences of commits into one unified history. In the most frequent use cases, git merge is used to combine two branches. Again, this means that git merge is often used in conjunction with git checkout for selecting the current branch and git branch -d for deleting the obsolete target branch. The current branch will be updated to reflect the merge, but the target branch will be completely unaffected. Note that all of the commands presented below merge into the current branch. The git merge command lets you take the independent lines of development created by git branch and integrate them into a single branch. Our integration was successful and, if our feature work on "contact-form" is finished, we could safely delete that branch.Merging is Git's way of putting a forked history back together again. Looking at our project's commit history, we'll notice that a new commit was created: a so-called "merge commit" that represents the actual "melting knot" that combines the two branches. With such perfect preparation, the actual merge process itself is easy as pie: $ git merge contact-form The last thing to check before actually starting the merge process is our current HEAD branch: we need to make sure that we've checked out the branch that should receive the changes.īut since we just updated "master" and already performed a "git checkout master", we're good to go! Starting the Merge ![]() If properly configured, a plain "git pull" should suffice (after making "master" our active branch): $ git checkout master We must update "master" before we can integrate our own changes. The remark tells us that "master" has received new changes on the remote. ![]() Start with a "git fetch", followed by a "git branch -va": $ git fetch Both your local feature / bugfix / branch and the receiving branch should be updated with the latest changes from your remote server. Preparing to Mergeīefore merging your code into one of your project's long-running branches (like a "development" or "master" branch), make sure that your local repository is up to date. Our goal is to integrate the changes from "contact-form" back into "master". Let's assume a very simple example scenario: ![]()
