If only one branch changes any file, you'll not have a merged conflict. We have just seen that a merge conflict can occur if different branches change the same part of the file in different ways. A person needs to decide how to write fileA.txt. Git doesn't know how to write fileA.txt, then you have a merge conflict. However, when Git tries to combine the work, it notices that the second line of fileA.txt is different on each branch. When you perform a merge, Git tries to automatically create a merge commit, combining the work of commits B and C. You cannot use a fast forward merge because commit C has been made to the master branch after you created the feature two branch. Now you are ready to merge your feature two work into the master branch. Commit B contains the string feature two as the second line of the fileA.txt file. Now let's say that you have finished feature two and made a commit B on the feature two branch. Commit C contains a fileA.txt file that includes the string feature three as the second line of the file. While you are working on the feature two branch, someone makes commit C on the master branch. Then let's say that you create a feature two branch based on commit A. That commit contains a fileA.txt file containing the string feature one. In this example, we start with commit A on the master branch. In that case, a merge conflict occurs and a person needs to make a decision on how to resolve it. However, there are cases where multiple branches make different changes to the same part of a file. If you perform a merge with a merge commit, Git takes on the responsibility of combining the work of multiple branches and placing the result into a single merge commit. We will start with a merge conflict overview. In this video, we'll discuss resolving merge conflicts. It will probably take you about 5-10 hours to go through one of the two paths, but your mileage may vary. This course tries to be as concise as possible. However, most of the knowledge that you gain in this course applies to Git itself, and you can apply this knowledge to other hosted Git providers (such as GitHub). Bitbucket is free for teams of up to 5 people, including private repositories. This course uses Bitbucket () as the hosted provider for remote Git repositories. If you use the command line path through the course, you can also use Linux. You can watch the videos and take the quizzes from your phone if you want, but the hands-on labs require you to have a Windows or Mac computer. Besides, repetition is good for learning :) Eventually, you might want to go through both paths, so that you can decide which tool to use for specific tasks. If you are not experienced with a command line, we highly suggest that you go through the Sourcetree path. One path assumes that you have experience using a command line interface, and the other path uses the Sourcetree graphical client. This is especially true if you currently "know just enough Git to be dangerous". This course assumes no previous knowledge of Git, but if you do have experience with it, you may find this course to be both useful and challenging. In this course, you will not learn everything there is to know about Git, but you will build a strong conceptual understanding of the technology, and afterward will be able to confidently dig deeper on any topic that interests you. You could also use Git to manage the many continuously improving revisions of that book that you are writing. It is a core component of DevOps, continuous delivery pipelines and cloud-native computing. It is used by most major technology companies, and is assumed knowledge for many modern programming and IT jobs. This allows the team to continuously improve its product. Git manages team files for large and small projects. Git is open source software originally created by Linus Torvalds. The Version Control with Git course provides you with a solid, hands-on foundation for understanding the Git version control system.
