Git Basics for Developers: A Quick Guide

#Day_13 – Starting Git, GitHub & GitLab (DevOps Journey) Today, I started learning Git, GitHub, and GitLab, and this is one of the most important steps in my DevOps journey. 👉 Version control is not optional… it is a must for every developer and DevOps engineer. 🔹 What is Git? (Basic Understanding) Git is a version control system that helps track changes in code. Keeps a history of all changes Helps in teamwork Easy to go back to previous versions 👉 It is like a “save + history + backup system” for code. 🔹 Basic Git Commands git init – start a new repository git status – check current state git add . – add files to staging git commit -m "message" – save changes git log – see commit history 👉 These are the most used daily commands. 🔹 What is GitHub? GitHub is a cloud platform where we store our Git repositories. Store code online Share projects Collaborate with others 👉 It is widely used in industry. 🔹 What is GitLab? GitLab is similar to GitHub but also provides: Built-in CI/CD More control for DevOps Used in many companies 👉 Both GitHub and GitLab are important tools. 🔹 Working with Remote Repositories git remote add origin <url> git push – upload code git pull – get the latest code 👉 Helps in teamwork and syncing code. 🔹 Branching Concept git branch – create branch git checkout – switch branch git merge – merge changes 👉 Branching helps work on features without affecting the main code. 🔹 Collaboration Basics Multiple people work on the same project Use pull requests/merge requests Review code before merging 👉 This is how real companies work. 🔹 Why Git is Important in DevOps? Track every change Easy rollback Supports CI/CD pipelines Helps automation 👉 Without Git, DevOps is incomplete. What I realised today: ✔ Git is the backbone of development ✔ GitHub/GitLab make collaboration easy ✔ Version control is a must-have skill ✔ Every DevOps engineer uses Git daily 👉 Today was very important for my journey. Let’s keep learning and growing 💪 #Linux #DevOps #Git #GitHub #GitLab #Day13 #LearningInPublic #ITSkills #CareerGrowth #trainwithshubham #joshbatch10 #devopsengineer

🚀 Day 37 – Git & GitHub 🔧🌐 Today I learned about version control systems, especially Git and GitHub, which are essential tools for developers and DevOps engineers 💻 🔧 What is Git?

If you're starting your journey in DevOps or software development, there’s one tool you simply cannot ignore: 👉 Git (Version Control) This blog is a complete beginner-friendly guide that explains not just how to use Git, but why it exists and what problems it solves. Here’s what this blog/Attached PDF covers: 1) What version control is and why it’s essential 2) The problems teams face without version control 3) How code is shared using remote repositories 4) The complete Git workflow: → Pull → Work → Stage → Commit → Push 5) What a repository is and how Git tracks history 6) What merge conflicts are and how to handle them 7) How Git maintains full history and allows you to revert changes 8) Why commit messages matter 9) The 4 core components of Git: → Remote repo → Local repo → Staging area → Git client 10) Essential Git commands (git status, git log, git add, etc.) 11) How Git fits into DevOps (Infrastructure as Code) One key idea: Git is not just about storing code. It’s about tracking every change, collaborating safely, and being able to go back to any point in time when needed. This blog builds a strong foundation so that when you start using Git in real projects, everything makes sense instead of feeling confusing. You can read the complete blog using the link below, or you can review the attached document—both contain the same information: [ https://lnkd.in/gqV9j6-W ] Quick takeaway: If you understand Git, you understand how modern development and DevOps workflows actually work. Comment what should I write about next? Feel free to comment below & I’ll try to create a post on your suggestion within a day. I can cover topics like: Git, Ansible, Jenkins, Groovy, Terraform, AWS, Networking, Linux, DevOps practices, Cloud architecture, CI/CD pipelines, Infrastructure as Code, or anything related. If you find the content useful, please share it with your network and drop a like 👍 it really helps these posts reach more Linux, DevOps, and Cloud folks. Your likes and shares are what keep me motivated to keep writing consistently.

Day 3 — Git and GitHub for DevOps As part of my daily DevOps posts, today I’m sharing one of the most important foundations in modern software delivery: Git and GitHub. Git is the version control system that helps track changes in code, collaborate safely, and manage different versions of a project. GitHub makes it easier to work with teams, review code, and support CI/CD workflows. Some essential Git commands and concepts: • git init — initialize a repository • git clone — copy an existing repo • git status — check current changes • git add — stage files for commit • git commit — save changes • git push — send changes to GitHub • git pull — get latest changes • git fetch — download changes without merging • git branch — create or view branches • git checkout — switch branches • git switch — modern way to switch branches • git merge — combine branches • git rebase — reapply commits on top of another branch (clean history) • git stash — temporarily save changes • git log — view commit history • git diff — see changes between commits/files • git reset — undo changes (careful usage) Key concepts: • Branching strategy • Pull requests (PRs) for code review • Conflict resolution • Clean commit history Git and GitHub are used in almost every DevOps workflow, especially for collaboration, automation, and CI/CD pipelines. I’ll continue posting one DevOps tool or concept every day. #Git #GitHub #DevOps #VersionControl #CICD #Automation #SoftwareEngineering #CloudComputing #DevOpsEngineer #Coding #TeamCollaboration #TechCommunity #LearningEveryDay #DeveloperTools #job #hr #hiring

🚀 DevOps Journey – Day 16 / 100 Today I explored Git Merge vs Rebase, Stash & GitHub basics 🔥 🔹 🔁 Merge vs Rebase (Interview Perspective) ✅ Git Merge • Combines branches with a merge commit • Preserves full history • Best for team collaboration ✅ Git Rebase • Rewrites commit history linearly • Cleaner & readable history • Best for local development 💡 Difference in One Line: 👉 Merge = Safe & history preserved 👉 Rebase = Clean & linear history ⸻ 🔹 📦 Git Stash (Temporary Save) • git stash → Save uncommitted changes • git stash list → View stash list • git stash apply → Reapply changes • git stash clear → Delete all stash ⸻ 🔹 🌐 GitHub Basics • Create account on GitHub • Create a repository • Default branch = main 🔹 🔗 Connect Local to GitHub • git remote add origin <URL> • git remote -v → Verify remote ⸻ 🔹 🚀 Push Code • git push origin branch • git push origin --all 💡 Note: Using HTTPS → Requires username + personal access token (PAT) instead of password ⸻ 🔥 Pro Tip: Use Merge in real projects, Rebase for clean commits before pushing! Consistency + Practice = DevOps Success 💪 #DevOps #Git #GitHub #Linux #VersionControl #100DaysOfDevOps #LearningJourney #Cloud #Automation #selflearning #devops #software

Sharing this Git commands guide — quite insightful. While I regularly use git push and git pull in my workflow, it’s always valuable to revisit and expand our understanding of other commands that can enhance development productivity.

🔹 Git in a Nutshell – Simple Understanding for Everyday Use 🔹 Git is an essential tool for every developer and DevOps engineer. This visual gives a clear overview of how the Git workflow actually works in real projects. Here’s a quick breakdown in simple terms 👇 👉 Create / Clone Start your project by creating a repo or cloning an existing one. 👉 Make Changes Work on your code, add features, fix bugs. 👉 Stage (git add) Select the changes you want to track. 👉 Commit Save your work locally with meaningful messages. 👉 Branching Create branches to work on features without affecting the main code. 👉 Merge / Rebase Combine your changes back into the main branch. 👉 Push / Pull Push your code to remote (GitHub/GitLab) and pull updates from others. 👉 Handle Conflicts When multiple people work on the same code, conflicts may occur — resolve them carefully. 💡 Key Tip: Good commit messages + proper branching strategy = clean and maintainable projects. This workflow is something I use daily in DevOps for CI/CD pipelines, deployments, and collaboration. #Git #DevOps #VersionControl #Learning #CI_CD #Developers #TechJourney #Github
