Have you ever wondered if using Git and GitHub offers the same experience in software development? Contrary to a common misconception, these two are distinct entities, serving different roles and owned by separate companies. So, what exactly are Git and GitHub, and how do they differ as software tools and services?
What is Git? Git is a widely used tool for managing code, with 70% of developers using it. It helps save different code versions in a repository, making it easy to track changes. Each change is recorded as a "commit." When you commit in Git, you'll see "commit to main," indicating the stable version of your project.
Git Repository Structure A Git repository has four key parts that help in managing code changes:
Working Directory: Your local space where you create and modify the project (write code). Staging Area (or Index): An intermediate area where changes are placed before committing. They are used for code review by team members before making them final. Local Repository: Your local storage where committed changes are stored. Corresponds to the hidden .git folder in your project directory. Central Repository: The main project is stored on a central server (like GitHub). Every team member has a local copy of this repository. The repository structure is internal to Git and is managed behind the scenes, making it transparent to developers.
Here are some essential commands related to the repository structure:
Add Changes to Staging Area:
Transfers your project changes from the working directory to the staging area.
Commit Changes to Local Repository:
git commit -m "Your message here"
Move your changes from the staging area to the local repository with a descriptive message.
Push Changes to Central Repository: Sends you committed changes from the local repository to the central repository (requires an internet connection).
What is GitHub? Git and GitHub are related but not the same. Git is a tool for managing code versions, while GitHub is a place to store those versions online.
GitHub lets you back up your code, share it, and work with others. It's like a cloud storage for your Git projects. Many organizations, big and small, trust and use GitHub because it's free and reliable.
To get started with GitHub, you need an account. Here's how:
Open a new tab in your browser. Go to github.com. Create an account. Check your email for a message from GitHub and follow the instructions to verify your email. Once your account is set up, you can use GitHub and explore its features, including GitHub Desktop, for an easier way to manage your Git projects.
Accessing the Github central repository via HTTPS or SSH When working with GitHub, you have two primary ways to access the central repository: through HTTPS or SSH .
Via HTTPS: The default way to access GitHub. Utilizes Lossless Compression Techniques to transfer changes efficiently. To link your local project to the GitHub central repository, use the following terminal commands:
git remote add origin http_url
Here, "origin" is the name given to the central repository, and "http_url" is the HTTPS URL of your GitHub repository.
Via SSH: Allows you to connect to Linux or other servers remotely. Eliminates the need to enter your username and password each time you push changes to GitHub. Here are the terminal commands for setting up SSH: Generate SSH Key:
ssh-keygen -t rsa -b 4096 -C "your_email@example.com" This generates an SSH key using the RSA cryptographic algorithm.
Enable SSH Agent:
This activates information about the local login session.
Add SSH Key:
Adds the SSH key to the agent.
Display SSH Key (if needed):
Use the displayed Key or its .pub file if connection issues arise.
Now, add the SSH key to your GitHub account:
Go to GitHub Settings -> New SSH Key -> Create Key . To test the connection: ssh -T git@github.com
This command verifies and activates the SSH key. Once done, refresh your GitHub page. This setup ensures secure and password-free access to your GitHub central repository using SSH. How Git and GitHub Handle Commands Differently Let's understand how Git and GitHub handle basic commands differently:
Git: Clone a Repository:
ssh -T git@github.comgit clone <repository_url>
Create a Branch:
git branch <branch_name> git checkout <branch_name>
Commit Changes:
git add <file_name> git commit -m "Commit message"
Push Changes:
git push origin <branch_name>
GitHub: Clone a Repository:
Similar to Git, using git clone <repository_url>. Create a Branch:
It is usually done on the GitHub website by clicking a button. Commit Changes:
This can be done on the GitHub website or by syncing local changes made with Git. Push Changes:
After committing locally, push changes to GitHub using git push origin <branch_name> . Git handles core tasks through the command line, while GitHub provides a user-friendly web interface for collaboration, adding features like pull requests and issue tracking. Both work together, offering flexibility in how developers interact with their projects.
