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. You will additionally learn to create branches and track files, along with creating a repository in GIT, GitHub, and much more. GitHub builds collaboration directly into the development process. Work is organized into repositories where developers can outline requirements or direction and set expectations for team members.
Personally, I prefer to use VSCode – it’s a pretty nice diffing tool. The output of this command can be seen in Listing 1. Don’t stage this newly appended content and run Git status -s again. This time you’ll see that dontreadme.md status https://remotemode.net/become-a-front-end-developer/git-fundamentals/ now says “MM”, one M is green, and the other is red. The current state of my Git repo is shown in Figure 21. You can imagine that afolder could be something like node_modules, or something that you actually wanted to get rid of.
Bike Shedding — Developer Opinions Explained
If you want to get a copy of an existing Git repository — for example, a project you’d like to contribute to — the command you need is git clone. If you’re familiar with other VCSs such as Subversion, you’ll notice that the command is “clone” and not “checkout”. This is an important distinction — instead of getting just a working copy, Git receives a full copy of nearly all data that the server has. Every version of every file for the history of the project is pulled down by default when you run git clone. By default, every git repository’s first branch is named `master` (and is typically used as the primary branch in the project). In other documentation and discussions, you may see “master”, or other terms, used to refer to the primary branch.
- Your dev tools or development environment need these files, but they’re downloaded or generated on the fly.
- In GitLab, you typically use a merge request to merge your changes, instead of using the command line.
- This is your source code, and you need plenty of things to help you keep control of what’s being committed.
- Also, I’m going to create another file in the root of my repo.
Tags are very similar to branches, but the difference is that tags are immutable. It means, tag is a branch, which nobody intends to modify. Once a tag is created for a particular commit, even if you create a new commit, it will not be updated. Usually, developers create tags for product releases. To instruct Git to ignore the env.txt and afolder folder, I’ll create a new file in the root of my repo called .gitignore. You can also choose to create a .gitignore file per folder and have those settings apply only to that folder and its children.
Syntax Desk Setups
You can push this and your remote repo will reflect these changes. Visit your GitHub repo, and you should now see a nice helpful message, as shown in Figure 12. See, in Figure 10, I effectively now have multiple versions of my code base. I can now revert back to a production version in “main” while switching to a dev version in “newchange”. At any point, you can run “git branch” to verify which branch you’re on and which branches are available locally. Inside this folder is a hidden folder called “.git”.
- First of all, Git remote lets me manage tracked remote repositories.
- Here, you’re making things, breaking things, and editing stuff, and edits don’t preserve history.
- What I wish to do now is instruct Git to ignore the “afolder” contents going forward.

When you completed your task in your branch if everything works fine the final step is to merge your branch with the parent branch (main/master/dev). By creating new branch,we can experiment without breaking what already works, several developers can work in parallel on the same project simultaneously. This will create a new Git repository in your local system.
Graphical Summary of Git¶
First let’s reset my repo to what’s checked into remote. Go ahead and execute the Git remote add origin command, as shown in the last snippet. The yellowish color indicates that my repo has unstaged changes. If I wish to see what the current status of my Git repo is, I can use the following command. Figure 1 shows my settings that have a few additional things I haven’t talked about.
Clone with HTTPS when you want to authenticate each time you perform an operation
between your computer and GitLab. To start using Git from your computer, you must enter your credentials
to identify yourself as the author of your work. The username and email address
should match the ones you use in GitLab. If your computer doesn’t recognize git as a command, you must install Git. To help you visualize what you’re doing locally, you can install a
Git GUI app.
Will I get a certificate after completing the GIT training?
Regardless of the name, just keep in mind that nearly every repository has a primary branch that can be thought of as the official version of the repository. If it’s a website, then the primary branch is the version that users see. If it’s an application, then the primary branch is the version that users download. This isn’t technically necessary (git doesn’t treat any branches differently from other branches), but it’s how git is traditionally used in a project. DVCS clients not only check out the latest snapshot of the directory but they also fully mirror the repository.
Now, running a Git status basically tells me everything that I just did. The way authentication works here is that by default, GitHub uses username password. So it also supports ssh, which is what I have set up on my computer. Finally, you can use credential helpers to use alternate mechanisms of authentication as well.
