🚀 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

⚡ Day 16 – Shell Scripting Fundamentals in DevOps Today’s focus was on making my scripts more interactive and reliable. I worked through: 🔹 User input with read — capturing numbers, strings, and service names directly from the terminal. 🔹 Conditional logic (if-else) — comparing numbers, checking strings, and handling multiple cases with elif. 🔹 File checks (-f) — writing a script that asks for a filename and confirms if it exists. 🔹 Service checks (systemctl) — building a script that asks for a service name and reports if it’s active or not. 🔹 Troubleshooting syntax errors — learning why spaces around [ ] and using the right operators (= for strings, -eq for numbers) are critical in Bash. 💡 Key takeaway: Shell scripting is unforgiving about syntax, but that’s what makes it powerful. Every space, operator, and quote matters — and mastering these details builds the foundation for automation in DevOps. #90DaysOfDevOps #Day15 #DevOpsKaJosh #TrainWithShubham #Linux #ShellScripting #LearnInPublic

Day 18 of #90DaysOfDevOps 💻🔥 Today I leveled up my Shell Scripting skills by learning how to write cleaner and reusable scripts. ✔ Created and used functions ✔ Worked with return values & local variables ✔ Learned strict mode (set -euo pipefail) for safer scripts ✔ Built intermediate scripts for real scenarios 💡 Biggest learning: Using strict mode helps catch errors early and makes scripts production-ready. ⚡ Real-world DevOps use: Functions + strict scripting are used in automation scripts, CI/CD pipelines, and system monitoring tools. Slowly moving from basic commands to real automation 🚀 #DevOps #Linux #ShellScripting #Automation #90DaysOfDevOps

Day 19 of #90DaysOfDevOps 💻🔥 Today I built my first real-world automation scripts using Shell Scripting. ✔ Created a log rotation script (cleanup + compression) ✔ Built a server backup script using .tar.gz ✔ Automated tasks using crontab scheduling 💡 Biggest learning: Automation isn’t just writing scripts — it’s about making systems run without manual effort. ⚡ Real-world DevOps use: These concepts are used in log management, server backups, and scheduled maintenance in production systems. From learning → to building → to automating 🚀 #DevOps #Linux #ShellScripting #Automation #Crontab #90DaysOfDevOps

🚀 Day 20 – Log Analyzer and Report Generator Today I built a Log Analyzer & Report Generator using Bash scripting 💻 🔍 What it does: ✔️ Validates input log file ✔️ Counts total ERROR / Failed logs ✔️ Extracts CRITICAL events with line numbers ✔️ Finds Top 5 most frequent errors ✔️ Generates a clean summary report 📄 ✔️ Archives processed logs automatically 💡 Key Learning: Logs are gold in DevOps — analyzing them properly helps detect issues early and improves system reliability.

#Day10/90 of my DevOps Journey: Mastering Linux File Permissions! Today was all about the power of the command line—from creating and manipulating files with touch, echo, and cat to managing data flow with redirection operators (> vs >>). I dived deep into File Permissions, learning how to transform a simple text file into an executable script using chmod +x and the crucial "Shebang" (#!/bin/bash). Understanding the diffrence between overwriting and appending data is a small step for a dev, but a giant leap for script automation and system safety! https://lnkd.in/eZihHNBU

Day 19 of learning and practicing DevOps 🔁 Today all about building actual automation scripts Worked on: • Log rotation script to compress and clean old logs • Backup script to create timestamped archives • Scheduling jobs using crontab • Combining everything into a maintenance script Important part: Understanding why log rotation and backups matter — without them, logs can fill up disk space and break systems. learning today --> automation + scheduling Instead of manually managing logs and backups, scripts + cron can handle everything in the background. This one is actually used in production environments.

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

💻 Exploring Shell Scripting: Small Commands, Big Impact Another step forward in my DevOps journey 🚀 Shell scripting is more than just writing commands — it’s about: ✔️ Automating repetitive tasks ✔️ Improving efficiency ✔️ Building scalable workflows 🔑 Key areas I worked on: • Bash scripting & execution • Variables and arguments • Control structures (if, for, while) • Automating daily tasks 💡 Why it matters? Because automation is the backbone of DevOps — saving time, reducing errors, and ensuring consistency. “The best way to predict the future is to automate it.” #ShellScripting #DevOps #Automation #Linux #ContinuousLearn

🚀 My 5-Days Journey Learning Shell Scripting | From Basics to Loops Over the past few days, I’ve been building my foundation in Linux shell scripting as part of my journey toward DevOps. Here’s what I covered: 🔹 Day 1: Variables – storing and reusing data 🔹 Day 2: User Input – making scripts interactive 🔹 Day 3: If Conditions – decision-making in scripts 🔹 Day 4: For Loops – automating repetitive tasks 🔹 Day 5: While Loops – continuous execution and monitoring 💡 Key Takeaway: Shell scripting is not just about writing code—it’s about automating real-world tasks and making systems efficient. 🎯 Next step: Applying these concepts to build real-world automation scripts for system monitoring and DevOps tasks. 🔗 GitHub Repository: Check out my scripts and projects here:https://lnkd.in/ggNUmtAF Consistency is key 🔑 — learning something new every day! #ShellScripting #Linux #DevOps #Automation #LearningJourney #CloudComputing
