🚀 Day 5 – Linux Basics for DevOps Headline: If you want to succeed in DevOps, get comfortable with Linux. 🐧 Most servers, cloud systems, and DevOps tools run on Linux. So understanding Linux basics is non-negotiable. 🔹 Why Linux Matters In real-world environments: Applications run on Linux servers Containers are Linux-based Cloud VMs use Linux 👉 You will interact with Linux daily in DevOps. 🔹 What You Should Know First Start with basic commands: 📌 Navigation pwd → current directory ls → list files cd → change directory 📌 File Operations mkdir → create folder rm → delete files cp → copy files mv → move/rename files 📌 Viewing Files cat → view file less → scroll file tail -f → live logs 🔹 Process & System Commands top → view running processes ps → process status df -h → disk usage free -m → memory usage 👉 These are very useful during production issues 🔹 Permissions (Very Important) Linux uses permissions: Read (r) Write (w) Execute (x) Commands: chmod → change permissions chown → change ownership 🔹 Real DevOps Use In real scenarios, you’ll: ✔ Check logs ✔ Restart services ✔ Debug issues ✔ Monitor system health All using Linux commands. 🔹 The DevOps Mindset Don’t just run commands. 👉 Understand what they do and when to use them. 💬 Discussion: Which Linux command do you use the most in your daily work? #DevOps #Linux #TechLearning #CloudEngineering #Beginners #SRE

🚀 Linux Roadmap for DevOps Engineers – From Beginner to Intermediate Sharing a structured visual roadmap covering essential Linux skills every DevOps Engineer should master. This roadmap guides you step-by-step: 🔹 Step 1: Linux Basics (Linux Commands, File Permissions, Viewing Files, System Navigation) 🔹 Step 2: Command Line Skills (Text Processing, Package Management, Process Monitoring, Disk Usage) 🔹 Step 3: Shell Scripting (Bash Scripting, Automation, Loops & Conditions, Deploy Scripts) 🔹 Step 4: System Administration (User Management, SSH & Cron Jobs, Log Monitoring, Server Configuration) 🔹 Step 5: DevOps-Focused Skills (Docker & Networking, File Systems, Security & Permissions, Production Environments) 💡 Practice daily on Linux using VMs or Cloud Servers. Learn → Script → Deploy → Repeat. A strong foundation in Linux is critical for working with CI/CD pipelines, containers, cloud platforms, and production infrastructure. #Linux #DevOps #CloudEngineering #SystemAdmin #Automation #Docker #Learning #Tech

🚀 Mastering Linux Commands: The Backbone of DevOps & System Administration If you're working in DevOps, Cloud, or System Administration, Linux is not optional — it's mandatory. Here are some essential Linux commands every engineer should know 👇 🔹 System Monitoring top / htop / btop → Real-time system processes free -h → Memory usage uptime → System load 🔹 Disk Management df -h → Disk space usage du -sh → Folder size lsblk → Block devices 🔹 Process Management ps aux → Running processes kill -9 PID → Force stop process pkill <name> → Kill by process name 🔹 Networking netstat -tulnp → Open ports ss -tulnp → Modern netstat ping <host> → Connectivity check curl <url> → Test APIs 🔹 File & Directory ls -la → List files cd → Change directory cp, mv, rm → Manage files find / -name file.txt → Search files 🔹 Permissions chmod 755 file → Change permissions chown user:group file → Change ownership 🔹 Package Management (Ubuntu) apt update && apt upgrade apt install <package> 💡 Pro Tip: Don’t just memorize commands — understand when and why to use them, especially during production issues. 🔥 In real DevOps scenarios, these commands help you: ✔ Debug live servers ✔ Monitor performance ✔ Fix outages quickly ✔ Manage infrastructure efficiently Start practicing daily — Linux is a skill that compounds over time. #Linux #DevOps #SystemAdmin #CloudComputing #Kubernetes #AWS #Docker #ITSkills

This #Linux commands #CheatSheet deserves a repost. Oh, here's a BIG shoutout these Linux distros that ALWAYS provide a rock solid RELIABLE computing EXPERIENCE for their users and #WindowsRefugees abandoning #Windows7, #Windows8, #Windows10 or #Windows11 on the desktop of things: #Debian, #LinuxMint / #LMDE / #LMDE7, #MXLinux, #Kubuntu, #ZorinOS, #Fedora, #UbuntuMATE, #UbuntuBudgie, #OpenSuse. Now, IF you absolutely plan on fleeing #WindowsServer in order to save a boatload of cash on licensing, you will NOT be disappointed with these: #Debian, #AlmaLinux or #RockyLinux (both are drop-in replacements for #RHEL aka #RedHat's #EnterpriseLinux). Note: 🤔 I got BIG RESPECT for Windows on the "server side" though IF you MUST manage a #Windows environment. I have had nothing but great computing experieinces with #WindowsServer2012R2 #WindowsServer2016 & #WindowsServer2019. These editions have NEVER ever let me or my clients down in the past when running #QuickBooksPOS aka #QBPOS aka #QuickBooks #PointOfSale. They just run & run & run without any complaints. 🤔
