Git diff command1/19/2024 The output returned by the Git Diff command can be a little complicated to understand. We can also pass the name of a file to the above commands to compare the versions of just a single file. This is just a way to compare the branch with the commit point from which it originated to see what all we have done with the branch since its creation. To compare the latest commit of one branch with the commit of the common ancestor of the two branches we use the … (triple dot) notation. We can also use just a single space between the names of two branches to do the same thing. To compare the latest commit of one branch with the latest commit of some other branch, we can use the. We can also compare the differences between different branches by using the git diff command. We can also pass a specific file name in the above commands to compare the differences for a single file. To see the changes between the versions of files that were previously committed and the version on which you are currently working: $ git diff We can use the HEAD to see the difference in the versions of files for a previous commit and the most recent commit. We need to know the hash of the two commits that we want to compare. We can compare a file that has been committed several times and see the changes made to the files for each commit. Running the above two commands without giving the file name will return the changes made to all the files. To compare a staged file with its last committed version we can use the -staged option. The above command will not be able to tell us about the changes made to a staged file. To view the changes made to a file since the last time it was staged: $ git diff Let’s take a look at how to use the Git Diff command for these entities. These entities can be files, commits, or branches. Git Diff can be used to compare the changes between different entities. Git Diff helps us in viewing these changes and assists us to better understand how our project changed over time. When working with hundreds of lines of code and altering just a few lines among them, it becomes a tedious task to find those few lines that we had altered. In most cases, the two files that are given as input to Git Diff will be two different versions of the same file. Git Diff also uses a diff function to tell us about the changes we have made to our files. It is a function that takes two files as input and returns the difference between them. Diff Commandĭiff is short for the word difference. When working with multiple files, we may forget the changes that we have made since the last commit or we just want to check the changes that we have made before finally committing them. We can compare the changes made to files, commits, or even different branches. Git Diff is a command that helps us to see the changes that we have made to a particular entity.
