Git Fundamentals Free Online Course

You will see how we can use the features of Git to work on and create a final version of the list. We could have also created our own branch off of the chapter-3-collaboration branch. This would let us work without having to worry about merge conflicts until the very end. Git tells us our branch and the remote branch have 1 commit different from each other. It also tells us that we have some “unmerged paths”—that we’re currently mid-merge and we need to fix the conflicts. After running git pull, if we run git status once again we’ll see that everything is up to date.

Go and check out how to do one here and give me a pull request with your code file. By using the porcelain git fetch origin main, Git will download the remote branch and synchronize it with a new local branch called origin/main, also known as the upstream branch. To work with remote branches, we have to add a remote to our local repository, using the porcelain command git remote. The second command git branch -M main changes your main branch’s name to “main”. The default branch might be created as “master”, but “main” is the standard name for this repo now.

Before using Git we should know why we need it

A file in the staged state means it is ready to be committed. In this state, all necessary changes have been made so the next step is to move the file to the commit state. Before https://remotemode.net/become-a-front-end-developer/git-fundamentals/ we “add” and “commit” our files, you need to understand the stages of a file being tracked by Git. For our project, we’ll make a to-do list written in a text (txt) file.

• The GIT basics program will help you understand the three-stage workflow in GIT (a version control system, or VCS) and set up GIT in your system.
• But if you have your project hosted on GitHub, you can access and download that project with a command on whatever computer you have access to.
• If you want to get started on learning about Git technology, you’ve come to the right place.
• For our project, we’ll make a to-do list written in a text (txt) file.

You should try doing it yourself so you understand how it works. As a hint, add the file and then commit with a message (refer to the previous section for details showing you how to do that). We created the new branch from the state of our last commit. After making changes to the file, it moved to the modified state – but it’s not yet staged for commit, so you can’t push it to GitHub yet. Git has not taken a final snapshot of this current state as it’s only comparing the changes we have made now with the last snapshot. Let’s make changes to the file and take note of the states.

Search code, repositories, users, issues, pull requests…

This is because we are not creating a new branch but rather switching to an existing one. You can check all the branches that exist in your repo by running the git branch command. The first line has information about my PC and the path to where the folder exists. The second line is the command git init, and the third line is the response sent back telling me that my repository (repo) has been initialized.

• The default branch might be created as “master”, but “main” is the standard name for this repo now.
• We’re currently on the main branch locally, so we need to tell GitHub to update its own main with the new commit that we made.
• 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.
• So Git can be used to store content — and it is mostly used to store code because of the other features it provides.

This article was a bit too long, but I could express the main topics I think are important to understand about Git. If we want to change the tag pointer, we must delete it and create another one with the same name. By using git reset –hard, any difference between revisions will be discarded and they won’t appear in the index. The following porcelain commands are widely used, which manipulate the Git references under the hood.

How to push a repository to GitHub

We can see that, given a commit with a parent, we can traverse all commits recursively, through all their trees until we get to the final blobs. Once the promotion is done, time to add some metadata to the tree, so we can declare the author’s name, date and so on. In the tree object, Git returns all the objects that were added to the index.

The rebasing conflict can also be solved with the help of the Git merging tool. For new users, using the terminal view can seem a bit complicated. We will keep it really simple, and learning this way gives you a good grasp of how Git works. Seriously, mention your Git username and email address, since every Git commit will use this information to identify you as the author.

Remote Commands

So I will create a new branch called test to see what my list would look like with more tasks included. A conflict occurs when merging two changes that have changed the same line in a file. If two commits have changed the same line in a file, Git doesn’t know which commit’s changes to use, and it will require you to make the choice. Our local repository now knows about the presence of these new commits, but we haven’t done anything with them yet.
