Hello dev.to community! 👋
Yesterday, I shared the DevOps Roadmap 2025 (Step by Step) and kicked off my learning journey. Today, let’s dive into the first milestone → Linux.
🔹 Why Linux for DevOps?
Almost every DevOps tool and cloud platform runs on Linux. If you’re aiming to be a DevOps Engineer, Linux is your foundation. It helps you:
Understand how servers actually work
Manage processes, files, and permissions
Write shell scripts to automate tasks
Troubleshoot issues in production environments
🛠️ Linux Topics I’m Starting With:
✅ File system navigation (cd, ls, pwd, tree)
✅ File management (cp, mv, rm, touch, mkdir)
✅ Permissions & ownership (chmod, chown, groups)
✅ Process management (ps, top, kill, systemctl)
✅ Package management (apt, yum, dnf)
✅ Bash scripting basics (loops, conditions, functions)
💡 Hands-on Practice Ideas
Write a shell script to automate backup of a folder
Monitor CPU & memory usage using top and log it
Set up a simple cron job for daily tasks
🎯 Key Takeaway
If you’re new to DevOps → start with Linux. It’s not just a skill, it’s the environment where everything else (Docker, Kubernetes, CI/CD tools) will run.
👉 Tomorrow (Day 3), I’ll be covering Git & GitHub basics for DevOps — version control is the next step before we move to CI/CD.
Let’s keep building step by step 💪
