![]() ![]() You start by indicating a point in history that contains the “thing” you’re trying to identify the origin of-that’s typically a bug-and another point where you’re sure the code doesn’t contain said element. Git bisect is a powerful command that allows you to search throughout your project’s history using a binary search. They’re both useful, but each offers very different results. Git blame, on the other hand, tells you who was the last one to touch each line of the code. In short, git log gives you the overall history of the file through the entire timeline. With the syntax git log - you can use it to see all the commits that touched a given file. Git log is one of the most well-known commands in Git you use it to learn about the history of a project. “The only difference between this command and git-blame is that they use slightly different output formats, and this command exists only for backward compatibility to support existing scripts, and provide a more familiar command name for people coming from other SCM systems.”įor comparison, here you see the outputs of git blame and git annotate side by side: Git Blame vs. What is the difference between them? To make a long story short, they’re virtually the same. There’s another command very similar to git blame called git annotate. Let’s briefly cover how git blame relates to other Git commands. Having covered the very basics, let’s go a bit deeper. ^2e9344d (Haacked 14:23:45 -0800 1) # SeeGit - The Git Repository Visualizerģ2aef720 (Haacked 16:06:17 -0800 3) This is a little experiment in creating a realtime git repository visualizer.Īs you can see, the results from git blame contain the following parts for each line:įirst, the commit hash identifying the commit that last modified the lineįinally, the actual content of the file’s line, preceded by its number You’ll start by cloning a repo on GitHub:Īfter the cloning is complete, access the created folder: In its most basic form, this command “blames”-that is, indicates the authorship-of all lines in a file. ![]() Git blame is the command that can tell you who was the last person to modify each line of code and when. Or maybe you’re struggling to understand a piece of code and want to reach out directly to the author to ask them about it. This is useful, for instance, if you’re trying to determine when a bug was introduced. Knowledge of at least the most basic Git commandsĭuring development, you’ll often want to know who made a specific change. If you want to follow along with our examples, there are some basic requirements: In this guide, you’ll learn more about this command: how exactly it works, what the main command line options are, how it differs from similar commands, and much more. This information is valuable in many scenarios, as you’ll see-such as investigating when and how bugs were introduced. With this command, you can find out the authors of code changes in varying levels of detail. Git, of course, isn’t an exception-among the various Git commands you should be aware of is git blame. Version control tools are great at a variety of things, one of which is recording authorship of changes. ![]()
