Hey Geeks! 👋

Mastering Linux is a must-have skill for any DevOps engineer. Whether you're managing servers, automating deployments, or troubleshooting issues, Linux is at the heart of it all. Let’s dive into some essential commands and concepts!

🔹 Why Linux is Essential for DevOps

Linux is the backbone of modern DevOps, cloud computing, and infrastructure automation. As a DevOps engineer, you'll work with:
✔ Servers (Most run Linux, especially in the cloud)
✔ Containers (Docker/Kubernetes rely on Linux kernels)
✔ Automation & Scripting (Bash/Python are key)
✔ Networking & Security (Firewalls, SSH, permissions)

Since 90% of the cloud runs on Linux, mastering it is non-negotiable!

📂 Basic Linux Commands

1. File & Directory Operations

2. File Permissions & Ownership

3. Viewing & Editing Files

🛠 DevOps-Specific Linux Skills

1. Process & System Monitoring

2. Networking

3. Package Management

🔧 Pro Tips for DevOps

✅ Use grep & awk for log analysis
✅ Automate tasks with cron jobs
✅ Master ssh for remote server management
✅ Learn shell scripting (#!/bin/bash) for automation

🚀 Advanced DevOps Linux Skills

✅ Bash Scripting – Automate repetitive tasks
✅ Cron Jobs – Schedule scripts (e.g., backups)
✅ Master ssh for remote server management
✅ SSH Key Management – Password-less logins
✅ Log Analysis – grep, awk, sed
✅ Learn shell scripting (#!/bin/bash) for automation
✅ Containerization – Docker relies on Linux namespaces & cgroups

💡 Test Your Skills! Challenge-1:

Write a Bash script that:
1️⃣ Checks disk space (df -h)
2️⃣ Lists top 5 memory-consuming processes (ps aux --sort=-%mem | head -6)
3️⃣ Saves the output to /var/log/system_check.log with a timestamp

 💡 Test Your Skills! Challenge-2:

Write a Bash script that:
1️⃣ Creates a backup of a directory
2️⃣ Compresses it into a .tar.gz file
3️⃣ Logs the operation with a timestamp

The Original Linux OS Fit on a Floppy Disk:

Linus Torvalds released the first Linux kernel in 1991, small enough to fit on a 1.44MB floppy. Today, it’s the OS of choice for supercomputers, Mars rovers, and your smartphone!
