Git and GitHub are two essential tools that are widely used in the software development industry. They are used to manage the version control of code, collaborate with team members, and track changes in the code. Git is a distributed version control system that allows you to keep track of the changes made to your code and revert back to any previous version of your code. GitHub is a web-based platform that provides a hosting service for Git repositories.
In this beginner’s guide, we will explore the basics of Git and GitHub and how you can use them to manage your code.
The first step is to install Git on your computer. You can find the instructions to install Git on your specific operating system on the official Git website. Once Git is installed, you can open the command prompt or terminal and type `git –version` to verify the installation.
Creating a Repository
A repository is a central location where all your code is stored. To create a repository, you need to create a folder on your computer where you want to store the code and initialize it as a Git repository by using the command `git init` in the terminal.
After creating a repository, you can add files to it by using the command `git add
Once you have added the necessary files to the staging area, it is time to commit the changes. Committing means to take a snapshot of the changes so that you can easily revert back to a previous version if required. To commit the changes, use the command `git commit -m “Commit message”` in the terminal. The commit message should be descriptive so that you can easily understand what changes were made in that commit.
You can view the history of your commits by using the command `git log` in the terminal. This command will show you a list of all the commits made to your repository.
Branching is a feature that allows you to create a copy of your code and work on it separately. This feature is particularly useful when you want to experiment with new features without affecting the main code. To create a new branch, use the command `git branch
When you are ready to merge your changes with the main code, use the command `git merge
Collaboration with GitHub
GitHub is a web-based platform that provides a hosting service for Git repositories. It allows you to collaborate with other developers by sharing your code. To collaborate with others, you need to create a GitHub account and create a repository on the platform. Once you have created a repository, you can push your changes to the remote repository by using the command `git push
In conclusion, Git and GitHub are powerful tools that can revolutionize the way you work on your code. This beginner’s guide provides you with the basics of Git and GitHub and helps you get started on managing your code effectively. With practice, you will become more proficient and be able to collaborate with others on a more advanced level.
