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.

It's becoming increasingly clear to me as I learn more about DevOps that Git is more than simply a coding tool; it's essentially a fundamental component of everything else. Collaboration, change review, and the safe deployment of work are all impacted by version control. I've been taking more time lately to comprehend things that I used to ignore: • How local work is truly connected to GitHub via remotes • The significance of SSH setup • When to utilise the stash • The differences in behaviour between reset and revert • Why.gitignore is more important than it first appears Even understanding commit history properly with <git log> and <git show> makes it easier to see how projects evolve over time. Still building confidence with it, but definitely seeing why strong Git habits matter early. #DevOps #LearningInPublic #CoderCo

🚀 Day 6 of #100DaysOfDevOps Challenge Today I explored one of the most fundamental pillars of modern software development — Version Control Systems (VCS) and Git 🔥 📌 Here’s what I learned today: 🔹 What is Version Control System (VCS)? A system that tracks changes in code over time, enabling collaboration, history tracking, and easy rollback when needed. 🔹 Why is it important? ✔️ Maintains complete history of changes ✔️ Enables team collaboration ✔️ Supports branching & experimentation ✔️ Ensures code safety and integrity 🔹 What is Git & Why Git? Git is a distributed VCS known for its speed, flexibility, and powerful branching capabilities. It’s widely used in DevOps and CI/CD pipelines. 🔹 Git Stages Explained: 📂 Working Directory – Where you create/modify files 📌 Staging Area – Where changes are prepared (git add) 📦 Repository – Where changes are permanently stored (git commit) 🔹 Git Lifecycle: Modify ➝ Stage ➝ Commit ➝ Push ➝ Pull 🔹 Linux Commands to Install Git: sudo apt install git -y sudo yum install git -y sudo dnf install git -y 🔹 Git Logs: Tracking history using commands like: git log git log --oneline git log --graph 💡 Key Takeaway: Mastering Git is not optional — it’s a must-have skill for every DevOps Engineer to manage code efficiently and collaborate seamlessly. 📈 Every commit you make is a step closer to becoming a better engineer! 🔥 What’s next? Diving deeper into branching strategies and Git workflows! #DevOps #100DaysOfDevOps #Git #VersionControl #Linux #CloudComputing #SoftwareDevelopment #DevOpsJourney #LearningInPublic #TechGrowth #CI_CD #Automation #Programming #Developers #flm #Engineering #CareerGrowth #OpenSource #TechCommunity #BuildInPublic 🚀

Today I strengthened my understanding of version control with some important Git commands: 🔹 git clone – Learned how to copy a remote repository to my local system 🔹 git fetch – Understood how to retrieve updates from a remote repo without merging 🔹 git merge – Practiced combining changes from different branches These commands are fundamental for collaboration and managing code efficiently in real-world projects. Step by step, I’m building a strong foundation in DevOps and version control. 💻 #Git #VersionControl #DevOps #LearningJourney #TechSkills #SoftwareDevelopment #frontlinesedutech #flm #frontlinesmedia

🚀 Git feels complicated… until you see the whole picture in one flow. If you’re starting with Git, terms like commit, push, pull, merge, rebase can feel overwhelming. I was there too - trying to memorize everything without understanding how it connects. Here’s the simple way to look at it 👇 🔹 Git = Version Control System Tracks every change in your code and lets you go back anytime. 🔹 Works Locally First You write code → save changes → commit locally. 🔹 Then Sync with Remote (GitHub) push → send your code to remote repo pull → get latest changes clone → copy repo to your system 🔹 Collaboration Made Easy branch → work on features safely merge → combine changes PR (Pull Request) → review before merging fork → your own copy of a repo 💡 The key mindset shift: Git is not about commands… it’s about flow Local → Commit → Push → Collaborate → Merge Once you understand this flow, everything starts making sense. If you're learning DevOps or development, mastering Git is non-negotiable. #Git #GitHub #DevOps #VersionControl #Programming #Developers #TechLearning #OpenSource #SoftwareEngineering

🚀 Day 39 – Git Merge Conflicts & Resolution ⚠️🔧 Today I learned about merge conflicts in Git and how to resolve them — an important skill when working in team projects 💻 ⚠️ What is a Merge Conflict? A merge conflict occurs when two changes are made to the same file or line of code in different branches, and Git is unable to automatically merge them. 🔍 When Do Conflicts Happen? Two developers edit the same file Same line is modified in different branches Changes overlap ⚙️ How to Identify Conflict When merging, Git shows: <<<<<<< HEAD Your changes ======= Other branch changes >>>>>>> feature 🛠️ Steps to Resolve Conflict 1️⃣ Open the conflicted file 2️⃣ Identify the conflicting code 3️⃣ Edit and keep the correct version 4️⃣ Remove conflict markers 5️⃣ Add and commit 👉 Commands: git add . git commit -m "resolved conflict" 💡 Best Practices ✔ Pull latest code before starting work ✔ Use small commits ✔ Communicate with team ✔ Avoid editing same file simultaneously 📌 My Learning Today Understanding merge conflicts helped me realize how important collaboration and proper version control are in real-world projects. Resolving conflicts is a key DevOps skill 💪 #Git #MergeConflict #DevOps #VersionControl #CloudComputing #LearningJourney #TechSkills #WomenInTech #CloudEngineer

🚀Day 34/90 Days DevOps Challenge - Introduction to Git & Basic Commands Today I completed Shell Scripting and started a new tool: Git & GitHub. This marks a shift from scripting to version control, which is a core part of DevOps. Git is a distributed version control system used to track and manage changes in source code efficiently. 🔹 What Git Helps With It tracks: • Who made the changes (author) • What changes were made • When the changes were made It solves major problems like collaboration, tracking code history, and maintaining backups. 🔹 History of Git Before Git, developers faced issues in collaboration and version tracking. Tools like BitKeeper were used but had limitations. Git was introduced by Linus Torvalds in 2005 as a free and open-source solution. 🔹 Git Workflow (Very Important Concept) Working Directory → Staging Area → Local Repository → Remote Repository Understanding this flow is critical. If you skip this, Git will always confuse you. 🔹 Core Git Operations • Adding → Move files to staging area • Committing → Save changes in local repo • Pushing → Upload code to remote repo • Pulling → Download latest changes 🔹 Basic Commands I Practiced • git init → Initialize a repository • git config user.name / user.email → Set identity • git add <file> → Add file to staging • git add . → Add all files • git status → Check file status • git commit -m "message" → Save changes • git log → View commit history • git remote add origin <url> → Connect to GitHub • git remote -v → Verify remote connection • git push origin master → Push code to GitHub 💡Key Learning Git is not about memorizing commands. It’s about understanding the flow of how code moves from your system to a shared repository. 📌 Tomorrow’s Topic: pulling, fetch & cloning in Git #90DaysOfDevOps #DevOps #CICD #Docker #Kubernetes #AWS #terraform #ansible #prometheus #grafana #CloudComputing #InfrastructureAsCode #LearningInPublic #FreshGraduate #CloudEngineer #Linux #Git #GitHub #VersionControl

DevOps Concept of the Day: Git Basics Git tracks every code change, enabling collaboration, rollbacks, and full audit history. Commits = snapshots, branches = parallel work, pull requests = review gates to merge. Today's DevOps/MLOps update (ArgoCD): stable: Bump version to 3.3.7 on release-3.3 branch (#27377) Signed-off-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by:… https://lnkd.in/dcsfY_Ni Why it matters: Staying current with releases means your pipelines stay secure, efficient, and compatible. #Git #DevOps #VersionControl #GitHub

Git Series | Day 9: Optimization & Deployment — Squash, Cherry-Pick, and .gitignore 🚀 As I near the end of this series, I am focusing on the "polishing" tools that professional DevOps Engineers use to ensure their repositories are clean, secure, and ready for production. 1. Squash: Consolidating the Journey Why show 10 "work-in-progress" commits when one clean commit will do? Squash allows me to combine multiple commits into a single, meaningful entry. The Command: git rebase -i HEAD~number The Workflow: In the interactive editor, I keep the first commit as "pick" and change the others to "squash." The Benefit: It keeps the master branch history concise and high-level for senior reviewers. 2. Cherry-Pick: Surgical Precision Sometimes you don't want an entire branch; you just want one specific fix or feature. The Concept: Picking a single commit from one branch and applying it to another. The Command: git cherry-pick <commit-id> The Use Case: Great for pulling a critical hotfix from a development branch directly into production without bringing unfinished features along. 3. .gitignore: The Silent Guardian A professional repository should never contain logs, environment variables, or temporary build files. The Mechanism: By creating a .gitignore file, I tell Git which files to permanently ignore from tracking. Standard Exclusions: I typically exclude *.log, .env (security), and folders like /db or node_modules. The Result: Smaller repository size and zero risk of pushing sensitive credentials to GitHub. 4. Deployment: Hosting via GitHub Pages Git isn't just for tracking; it’s for delivering. I practiced hosting static web applications directly from a repository. Push your code to a new GitHub repository. Navigate to Settings > Pages. Select the master branch and save. Your application is live and accessible via a public URL! My use of .gitignore ensures that sensitive configuration data and "garbage" files never enter the version control system. I Streamline Code Reviews: By squashing messy development commits before merging. #Git #DevOps #100DaysOfCode #WebDeployment #GithubPages #CleanCode #SoftwareEngineering #SysAdmin #GitIgnore
