Git and GitHub are two essential tools in the world of software development. Git is a distributed version control system that allows developers to keep track of changes in their code and collaborate with other developers. GitHub is a web-based platform that provides hosting for Git repositories, making it easier for developers to share and collaborate on code.
In this tutorial, we'll be exploring Git and GitHub from the ground up, so even if you're new to software development, you'll be able to understand and follow along. By the end of this tutorial, you'll be comfortable using Git to manage your code and GitHub to share and collaborate with others.
What is Git?
Git is a distributed version control system that helps developers keep track of changes to their code. It's designed to handle small to large projects with speed and efficiency. With Git, you can track changes to your code over time, revert to previous versions, and collaborate with other developers.
How does Git work?
Git works by tracking changes to a project's files and directories. Each change you make to your code is recorded as a "commit". A commit is like a snapshot of your code at a particular moment in time. When you make a change to your code, you create a new commit with the changes.
In Git, you work with a local repository on your computer. You can make changes, create commits, and perform other Git actions on your local repository. When you're ready to share your code with others, you can "push" your changes to a remote repository, such as a repository hosted on GitHub.
Getting started with Git
To get started with Git, you'll need to install it on your computer. You can download the latest version of Git from the official Git website.
Once you've installed Git, you'll need to set up your Git configuration. This includes setting your user name and email address, which will be associated with your Git commits. To set up your Git configuration, open a terminal window and enter the following commands:
$ git config --global user.name "Your Name"
$ git config --global user.email "your.email@example.com"
Creating a Git repository
To create a Git repository, you'll need to navigate to the directory that contains your code. Then, run the following command:
csharpCopy code$ git add .
Once you've added the files, you can create a new commit with the changes by running the following command:
rubyCopy code$ git commit -m "Initial commit"
In this command, the -m the option allows you to specify a commit message. The commit message is a description of the changes you've made in this commit.
