![]() To compare the differences between two commits in Git, you can use the git diff command followed by the commit IDs of the two commits you want to compare. The git diff command displays any uncommitted repository modifications by default. The syntax for the git diff command is as follows:: git diff. It is commonly used in conjunction with git status and git log to analyze the condition of a git repository. We will learn how to do that in the next chapter. In this blog post, weâll explore the git diff command and show you how it can be used to quickly view the differences between two commits. These commands all compare two sets of things what is compared differs: git-diff-index compares the and the files on the filesystem. This command executes a diff function against a Git data source.In some cases, you would like to see a list of the previous commits. But, the basic git diff without any options will list the changes in our working directory that are. Like most git commands, there are many options we can add when using git diff. This can include changes between commits, branches, files, our working directory, or many other situations. I always run git status and git diff before making any commits, just so that I'm sure what has changed. Basically, the git diff command is used to view changes. " to unstage)įinally, if you run git status again you will see that there are no changes to be committed. The output would look like this, indicating that there is 1 modified file: On branch main Then again run git status to check the current status:.Next, let's go ahead and stage that change and commit it with the comments that we've learned from the previous chapters! In our case, as we only added 1 new line to the file, Git indicates that only 1 file was changed and that only 1 new line was added. So maybe kernel/sched.c hasnât actually changed, and itâs just that you touched it. In case that we remove a line, you would see a - sign instead. As with other commands of this type, git diff-index does not actually look at the contents of the file at all. +Git is awesome: here, the important part is the +, which indicates that this is a new line that was added.-1 +1,2 here git indicates that 1 new line was added.diff -git a/README.md b/README.md: here git indicates that it shows the changes made to the README.md file since the last commit compared to the current version of the file.If we were to run the command in our repository, we would see the following output: diff -git a/README.md b/README.mdĪs we only changed the README.md file, Git is showing us the following: You can check the actual changes that were made with the git diff command. As mentioned in the last chapter, the git status command gives us a great overview of the files that have changed, but it does not show us what the changes actually are.
