Quick guide to basic Git commands. Quickly learn the main commands to keep your projects up to date!

🤔 What's Git?

Git is a distributed version control system that tracks changes in any set of computer files. Git is often used to update GitHub projects from the machine to the server by specific codes.

💻 How to write a Git command?

  • Write on Visual Studio Code.

    • Open the VSCode
    • Go to the toolbar --> Terminal --> New Terminal (or just Ctrl + Shift + ')
    • Something like PS C:\Users\you> will apear on terminal. Use the command cd [path to project folder], like cd C:\Users\you\Projects
    • Write the commands!

  • Write on Command Prompt.

    • Open the Command Prompt. You can open it by Window Icon + R and write cmd. Or search 'Command Prompt' on Window search bar.
    • Something like C:\Users\you> will apear on terminal. Use the command cd [path to project folder], like cd C:\Users\you\Projects
    • Write the commands!

⌨️ Commands

Create the repository

  • The repositoty needs to be empty, without any file, even the README.md. Just don't select the checkbox 'Add a README file' when you create the repository. It's possible to do it in a full repository, but we'll not focus on that at the moment.

  • When it's created, use these commands on terminal:

git init

git add .

git commit -m "a message"
  • git init will create a file named as '.git' on your project folder.
  • git add . add your changes to your next commit.
  • git commit -m 'a message' Captures a snapshot of your project. Now you can push it to your GitHub repository.

Then write the three commands that appear on your repository. They look like this:

  • git remote add origin https://github.com/YourGitHubUsername/repositoryName.git
  • git branch -M main
  • git push -u origin main This creates a connection with your GitHub project and send the commit to your repository. You just need to use these three commands once. You already has your repository up to date! 🎉

To update again:

git add .

git commit -m "message"

git push origin main

Just this!

Your repository was changed by a collaborator, how to update your LOCAL CODE

git fetch

git pull

Creates a connection to the GitHub server and changes your code to match your project.

Now you can use the basics Git commands!
