You can use this command to search for code changers at different levels of detail. As you'll see, this information is valuable in many situations, such as investigating when and how bugs were introduced.
In this guide, you will learn more about this command: how exactly it works, what are the main command line options, how it differs from similar commands, and much more. let's dive in

What does Git Blame do in Git?
During development, you often want to know who made a particular change. This is useful, for example, when you want to determine when an error occurred. Or maybe you have trouble understanding some code and want to ask the author directly.

GitBlame: How does it work?
In its simplest form, this command "blames" all lines in the file; H. gives authorship. The syntax is:
the idiot is to blame
Let's see an example. Start by cloning the repository on GitHub:
Clone of Git https://github.com/haacked/seegit.git
Once the cloning is complete, navigate to the folder you created:
Now it shows the authorship of the file:
Git Blame README.md
The result will look like this:
Let's analyze it in a little more detail.

Git Blame: go deeper
Now that we've covered the basics, let's dig a little deeper.
differences and similarities
Let us briefly explain howthe idiot is to blamerefers to other Git commands.
Git Blame vs. Git Annotation
There is another command that is very similar.the idiot is to blamecalledgit annotation. What is the difference between them? In short, they are practically the same. I quote fromdocumentation:
"The only difference between this command and git-blame is that they use slightly different output formats, and this command only exists for backwards compatibility, support for existing scripts, and to provide a more familiar command name for people." that use other SCM systems they go to."
Here are the results to compare.the idiot is to blameIgit annotationNext to each other:
Git Culpa a Git Log
Git registryis one of the most popular commands in Git; They use it to learn more about the history of the project. with syntax
git log –You can use it to see all the commits that were in a particular file. So how is it different fromthe idiot's fault?
in summary,Git registrygives you the overall history of the file across the entire timeline.git bugOn the other hand, you will know who last touched each line of code. Both are useful, but each produces very different results.
Git Blame contra Git Bisect
go halfwayis a powerful command that allows you to search the entire history of your projectbinary search. You start by specifying a point in the story where there is a "thing" whose source you want to identify (this is usually an error), and another point where you are sure the code does not contain that item.go halfwayIt will then guide you through the history, allowing you to rate each stop as good or bad until the bisect command identifies the commit that caused the error.
When should the word "halve" be used instead of the word "fault"? Very simple: you usually usegit in halfin situations where you know little about how the error arose. If you don't even know which file is responsible for the problem, how are you going to use it?the idiot is to blame?
In other words:git bugis when you know where to look.
As with most Git commands:the idiot is to blamesupports many different options. Now we will show you some of the most important:
-e: show the email of the author
As you have seen, the standard output of the programthe idiot is to blamedoes not contain the author's email address. use these-miOption if you want to attach an email.
-l : print long commit hash
As you may have already noticed, the standard output shows the hash of the commit. If you want the full commit hash, add it-lOption (lowercase letter L).
-L: specify a line range
Now that we've discussed the lowercase "L" option, it seems appropriate to use the uppercase "L" as well.
you use-Lpossibility of providingthe idiot is to blameseries of lines instead of blaming the entire file. Let's take the README file again as an example, but this time only lines 2 to 5.
Git Blame README.md -L 2,5
The result looks like this:
--first-parent : Track only the first parent commit of a merge commit
Passivein Git, it can have zero, one, or multiple parents. Root commits have zero parents, most commits have one parent ito combineAdoptions can have two or more parents.
He--first fatherThis option tells Git to only follow the first parent in merge commits when assigning blame to a file. This is extremely useful, for example, when he needs to ignore changes made to another file.Zweig.
We have covered some options that you may find useful while you workthe idiot is to blameon the command line.
However, when working in a GUI context, credit information is often needed. Now we will see how to use it.the idiot is to blamein VS Code and in the GitHub interface.
