Day 17 of #90DaysOfDevOps 💻🔥 Today I dived deeper into Shell Scripting and learned how to make scripts more powerful and practical. ✔ Practiced for & while loops ✔ Worked with command-line arguments ($1, $#, $@) ✔ Built small scripts to automate tasks ✔ Learned basic error handling 💡 Biggest learning: Using arguments makes scripts reusable and dynamic — not just static commands. ⚡ Real-world DevOps use: Shell scripts are used daily for automation, deployments, monitoring, and backups. Consistency is building confidence 🚀 #DevOps #Linux #ShellScripting #Automation #90DaysOfDevOps

:::writing{variant=“social_post” id=“48321”} Ever run ls and feel like everything is under control… until ls -a exposes the chaos? 😅 That’s DevOps in a nutshell. What looks clean on the surface often hides: • Hidden configs • Environment variables • Secrets & keys • Dependency overloads The real work starts when you go deeper. 💡 Lesson: Don’t just trust what’s visible. Great engineers explore the hidden layers — that’s where the real problems (and solutions) live. #DevOps #Linux #EngineeringLife #Debugging #TechHumor #Learning :::

Day 28 of learning and practicing DevOps 🔁   Revision day — no new concepts, just strengthening everything learned so far till day 27 Worked on: • Revising Linux fundamentals (processes, permissions, systemd, networking) • Practicing shell scripting concepts and real-world scripts • Reviewing Git workflows (merge, rebase, stash, cherry-pick) • Understanding Git branching strategies (GitFlow, GitHub Flow, Trunk-Based) • Rechecking GitHub CLI and overall workflow   I also identified a few gaps: • LVM needs more hands-on • Branching strategies needed deeper clarity   Here are my notes: https://lnkd.in/gJt7eVeJ 📍   #DevOps #Linux #Git #ShellScripting #Revision #LearningInPublic #90DaysOfDevOps #TrainWithShubham

🚀 Day 21/90 – DevOps Learning Journey Today I created my own Shell Scripting Cheat Sheet after completing multiple hands-on scripting tasks. 🔹 What I covered • Bash basics, variables, arguments • If-else, loops, functions • File checks and logical operators • Powerful tools: grep, awk, sed, sort, uniq • Real-world one-liners for log analysis • Error handling using set -euo pipefail 💡 Key Learning Writing a cheat sheet forced me to organize concepts clearly — Now I can quickly debug scripts without searching documentation every time. This will be my go-to reference during real DevOps tasks 🚀 Consistency is building confidence day by day 💪 #90DaysOfDevOps #DevOpsKaJosh #TrainWithShubham #ShellScripting #Linux #Automation

YAML drift is the silent killer of config hygiene. Your services run, but you lose track of what changed. 🔥 `find . -type f -name '*.yaml' -mtime -1` Find starts at ., recurses; -type f keeps files; -name '*.yaml' filters YAMLs; -mtime -1 means last 24h. You're debugging a deploy and need to know which YAMLs changed in the last day. Capture the list and compare against commits or CI manifests. Small wins compound into reliability. This tiny one-liner keeps config drift honest.

📘 Leveling Up My Linux & Shell Scripting Skills 🚀 I’ve been diving deep into advanced Linux concepts and shell scripting, and it’s been an amazing learning journey so far! 🔹 Understanding how the shell works as a command interpreter 🔹 Writing efficient shell scripts to automate repetitive tasks 🔹 Exploring powerful tools like sed and awk 🔹 Learning about cron jobs for task automation 🔹 Strengthening system administration fundamentals One key takeaway: 💡 Automation is the backbone of efficiency in DevOps and system administration. This learning is helping me improve my problem-solving approach and work smarter with Linux systems. Excited to apply these concepts in real-world projects! 💻 #Linux #ShellScripting #DevOps #Automation #LearningJourney #SystemAdministration #TechSkills #CareerGrowth #FrontLineMedia #Frontlinsmedia #flm

🚀 Day 17 — Shell Scripting Today was all about making scripts smarter, reusable, and production-ready 🔹 What I worked on: Used for loops to iterate Built a while loop countdown script Learned command-line arguments ($1, $#, $@, $0) Created scripts to install packages automatically (nginx, curl, wget) Added error handling using set -e and || for safer execution Checked root privileges before running critical scripts 🔹 My favorite part: Building an auto-install script that checks if a package exists and installs only if needed — feels like real DevOps work! ⚙️ Checkout my work: https://lnkd.in/gjHHr-DS #90DaysOfDevOps #DevOpsKaJosh #TrainWithShubham #ShellScripting #Linux #Automation #DevOpsJourney #LearningInPublic #CloudComputing #Scripting #BeginnerToPro #TechGrowth

It’s been a while since my last update on my DevOps journey with CoderCo — but I’ve been putting in the work behind the scenes. Since completing Linux Fundamentals, I’ve been diving into Bash scripting, and things are starting to click. Some of what I’ve been learning: - Writing Bash scripts to automate simple tasks - Using tools like "awk" and "grep" to process data - Understanding exit codes and error handling - Working with "set -e" and "set -u" to make scripts safer and more reliable It’s a different feeling now — less “copying commands” and more actually understanding what’s happening. Still a long way to go, but definitely seeing progress. Next focus: building small scripts and applying this in real scenarios. If anyone has beginner-friendly scripting projects or tips, I’d appreciate it. #DevOps #Linux #Bash #Automation #LearningJourney

Revisiting Linux concepts is always valuable, and the BashBlaze – 7 Days of Bash Scripting Challenge is a great way to do just that. It introduces the fundamentals of Bash scripting while helping you build and refine your skills through a fast-paced, engaging approach. Whether you're just starting out or already have experience and want to strengthen your scripting abilities, this challenge offers daily exercises and practical examples to boost your understanding and confidence in Bash.
