What is Git? Git Tutorial for Beginners

We’ll go into more detail here as we make changes, but this message is basically saying we haven’t done anything—so no changes to report. However, there are times where you will overwrite or change the same piece of content as someone else and we’ll have to figure out how to settle those differences—and we’ll see that soon. The next thing we’ll do is create a new repository in Github. There’s definitely a lot more to Git than is presented here, but these are things you’ll learn as you work with it over time.

  • Git can be used for any type of industry from restaurants to colleges, so it is an important part of web design.
  • Part two of this tutorial explains the object
    database, the index file, and a few other odds and ends that you’ll
    need to make the most of Git.
  • Changes on the chapter-2 branch will not affect the main branch at all.
  • After committing, you push your new branch to the origin (git push origin ) and create a pull request.
  • Meaning to make sure you’re working on the latest version of the git repo each time you start working, a git pull command is the way to go.

We need to resolve the conflict by deleting one of the lines or combining the two lines into one (and remember to remove all of the extra markers that Git put in there as well). Visiting the URL above, we arrive at a page to open a new pull request. To view these changes, we’ll first look at the command line way (which I never use), and then a way that uses a GUI (which is 100% nicer). However, from the output above we can’t really tell what those changes were—we just know that they exist. Before we can commit a set of changes, we first have to stage them.

With Azure DevOps, you get Azure Boards, Azure Repos, Azure Pipelines, Azure Test Plans and Azure Artifacts. Let us see which version of Git we have and how can we update to the latest git fundamentals version. I have a Win 10 machine currently, which already has Git installed. Installation of Git comes with a Git terminal (Git Bash) and Git GUI (Image 1, Image2, Image3).

  • Please note that the fix branch contains all commits belonging to the main branch (C3 – C2 – C1), having only one commit ahead of the main (C4).
  • It was developed by Linus Torvalds in 2005 for Linux kernel development and It is used for keeping track of code changes and collaborating with others on code.
  • Git is telling us that our branch is “up to date” with something called origin/main.
  • And sometimes you just want to know “who wrote this crap”, and having access to that information is worthwhile ?.
  • With Git, every time you commit, or save the state of your project, Git basically takes a picture of what all your files look like at that moment and stores a reference to that snapshot.

This is an important section to absorb, because if you understand what Git is and the fundamentals of how it works, then using Git effectively will probably be much easier for you. As you learn Git, try to clear your mind of the things you may know about other VCSs, such as CVS, Subversion or Perforce — doing so will help you avoid subtle confusion when using the tool. Remember, a commit takes all of your staged changes and submits it to the repository. So stage only those changes that you want to commit to the repository.

Step 0: Make a GitHub Account. Duh.

Everything in Git is checksummed before it is stored and is then referred to by that checksum. This means it’s impossible to change the contents of any file or directory without Git knowing about it. This functionality is built into Git at the lowest levels and is integral to its philosophy. You can’t lose information in transit or get file corruption without Git being able to detect it. In this tutorial you will understand what Git is and how to use it on the remote repository platforms, like GitHub. Note that since we haven’t staged any changes yet, the staging area would still be empty.

We could have just done a git pull initially instead of first doing a git fetch, but I wanted to explain git fetch as it is useful in its own right. Our local repository now knows about the presence of these new commits, but we haven’t done anything with them yet. There are other files currently in our project (chapter-1.txt, chapter-2.txt), but those files didn’t change so there’s no need to show them. We’re now back on the main branch, and we get a quick status message saying we’re up to date with origin/main. The first thing we need to do is be on the primary branch that we want to merge changes into.

Introduction to Git

Let us open bash and first create a directory; we will add few files and then initialize the directory as a git repo. Git is a version control system used to track changes that generally occur in code and documents. GitHub is a platform that provides hosting for Git repositories and different tools for collaboration. We could have also created our own branch off of the chapter-3-collaboration branch.

  • Git repositories are not live-updating—they’re just a snapshot of the history at a point in time.
  • For example, to browse the history of the project, Git doesn’t need to go out to the server to get the history and display it for you — it simply reads it directly from your local database.
  • Or you can simply see what changes you made to your code over time.

It includes Azure Administrator interview questions and answers from real interviews, as well as advice from experts in the field. We will provide you with answers to some of the most common Windows administrator interview questions. Whether you’re just starting out or have been administering Azure for a while, this book will help you prepare for your next interview. Git branch creates a branch but we need to checkout that branch and then work. There’s also a lot of underlying Git “magic” (that is, code being run that you don’t understand yet), but you will learn and pick up more of this with time.

It is basically the history tab for your code editor(With no incognito mode ?). If at any point while coding you hit a fatal error and don’t know what’s causing it you can always revert back to the stable state. Or you can simply see what changes you made to your code over time. Using a VCS also means that if you screw things up or lose files, you can generally recover easily.

  • In the beginning, don’t make it any harder than it has to be!
  • The resulting commit history has both of the commits on the branch and our merge commit at the top.
  • These files are pulled out of the compressed database in the Git directory and placed on disk for you to use or modify.
  • Let’s execute gitadd .command to stage the changed files in registration branch.

Note that in general, Alice would want her local changes committed before
initiating this pull. In case you messed up something in the checkout, execute git checkout master to return to the latest commit (“Add poem 3”). Once you’ve done that, have a look at the contents of your project folder.
