Weekly Report: Version Control (Git)

Introduction

This week, I actively studied Git version control system. In this post, I will discuss Git setup, working with repositories, and essential commands, along with presenting my lab report.

📌 Git Basics

Git is a distributed version control system (VCS) that allows tracking file changes, managing different project versions, and collaborating on software development.

🔹 Key Terms:

• Repository — a project storage with a change history.
• Commit — a saved state of files with a description of changes.
• Branch — an isolated code version for working on new functionality.
• Merge — integrating changes from different branches.
• Remote Repository — a repository on a server (e.g., GitHub).

⚙️ Git Setup

🔑 Generating SSH Key

To work with remote repositories without entering a password, create an SSH key:

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

Add the key to the SSH agent:

eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_rsa

Copy the key and add it to GitHub:

cat ~/.ssh/id_rsa.pub

📌 Add key to GitHub: Go to SSH key settings

🛠️ Basic Git Configuration

Set up name and email:

git config --global user.name "Hovik Adjabkhanyan"
git config --global user.email "your_email@example.com"

Enable convenient encoding for Russian language support:

git config --global core.quotepath false

📂 Working with Repositories

🏗️ Creating a New Repository

Create a local repository and link it to GitHub:

mkdir my_project && cd my_project
git init
git remote add origin git@github.com:username/my_project.git

Add files and make the first commit:

echo "# My Project" > README.md
git add .
git commit -m "Initial commit"
git push -u origin main

📌 GitHub Repository: Open Project

🔄 Cloning an Existing Repository

git clone git@github.com:username/my_project.git

🌿 Working with Branches

Create a new branch:

git checkout -b feature-branch

Merge a branch:

git checkout main
git merge feature-branch

Delete a branch:

git branch -d feature-branch

📜 Lab Report

🔹 Course Directory Setup

📸 Creating Project Structure:

mkdir -p ~/work/study/2023-2024/Computer_Architecture
cd ~/work/study/2023-2024/Computer_Architecture
git clone --recursive git@github.com:username/study_2023-2024_arch-pc.git archpc

🖼️ Created Structure:

🔹 Independent Work Assignment

Add files to the repository:

git add .
git commit -m "feat: added lab report"
git push origin main

📌 View Repository: GitHub Repository

🎯 Conclusion

During the lab work, I: ✅ Set up Git and GitHub ✅ Created an SSH key for secure connection ✅ Organized the repository and learned essential commands
