![]() ![]() The output might have different colors, depending on your configurations. Just run git diff and you’ll see a result like the following: You’re now ready to perform your first comparison. The next step is appending a new line to the end of the file: We’ll start by creating a new repository, adding a single file and committing it: How Do We Use Git Diff? A Minimum ExampleĪfter covering the “what” and “why” of git diff, let’s proceed to the “how” by showing a minimal example of this command in action. You can see the changes made since the last commit, to review what will go into the next commit. It’s also possible to see the evolution of a single file through time, so you can, for instance, understand how a recent refactoring affected it. You can compare two branches to see the result of a future merge. It might help you track down how a bug was introduced. Why Do We Use Git Diff?īeing able to make comparisons in your project is extremely useful: ![]() We’ll talk about this format later for now, let’s focus on the reasons why this command is useful. The output from git diff comes in a standardized format that makes it easier to understand what changed but also serves the purpose of allowing the changes to be applied later. More specifically, it’s Git’s implementation of the famous diff utility. In a nutshell, git diff is the comparison command in Git. ![]() Let’s start our git diff guide by walking you through the fundamental questions. The tutorial will assume you’re comfortable working with the command line and know your way around the basic Git commands. You’ll learn about its main use cases and the most common options, always with practical examples. In this post, we’ll give you a complete yet focused guide for this Git command. In Git, you use the command git diff to compare commits, branches, individual files and more. In a similar fashion, if we write git diff branch2_name branch1_name then it will show all the changes being done in branch1 in green color and changes being done in branch2 in red color.Version control tools are great at many things. So now if I use the command to show all the changes on branch 2 then it will show the change done in the master branch in red color and the change done in branch2 only will be in green color only. So now if I create a file in branch1 add it into the staging area and then commit it then those changes are getting tracked in branch1, not in branch2. Git in branch1 that is what the change in between the 2 branches. ![]() Here we can see that when the command is git diff branch1_name brach2_name it is showing all the changes on the branch_name 2 that too in green color which means that those changes are staged and committed in that branch and in the second command which is just the reverse of the first command git diff branch2_name branch1_name it is showing all the changes in red color that means those changes are not tracked by ISRO CS Syllabus for Scientist/Engineer ExamĬomparing the two branches by using the above command.ISRO CS Original Papers and Official Keys.GATE CS Original Papers and Official Keys.DevOps Engineering - Planning to Production.Python Backend Development with Django(Live).Android App Development with Kotlin(Live).Full Stack Development with React & Node JS(Live).Java Programming - Beginner to Advanced.Data Structure & Algorithm-Self Paced(C++/JAVA).Data Structures & Algorithms in JavaScript.Data Structure & Algorithm Classes (Live). ![]()
