Strengthening Shell Scripting Expertise with Automation

🚀 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

Until now, I was running Linux commands one by one. Today I started learning how to automate them. That’s what I explored while getting into shell scripting in Linux. Instead of manually executing commands every time, I practiced how to write simple scripts that can run multiple steps automatically. What I practiced today: ✔ Creating a basic shell script (".sh" file) ✔ Understanding the shebang ("#!/bin/bash") ✔ Writing simple commands inside a script ✔ Running scripts using "bash" ✔ Making scripts executable with "chmod +x" What stood out: This felt like a big shift. Instead of repeating the same commands again and again, scripting allows you to automate workflows which is exactly what real DevOps and system administration work depends on. Hands-on progress: ✔ Created my first shell script ✔ Executed multiple commands through a script ✔ Understood how Linux runs scripts ✔ Learned how execution permissions affect scripts Key takeaway 💡 Running commands is useful. Automating them is powerful. This is where Linux starts becoming a real engineering tool. #Linux #DevOps #ShellScripting #Automation #SystemAdministration #Infrastructure #TechLearning

🚀 I created a 10-Day Shell Scripting Challenge for Linux, DevOps & System Engineer enthusiasts Goal → Help you learn shell scripting from scratch and automate repetitive tasks ⚡ 📅 Day 1 – Basics of Shell Scripting 🔹 What you will learn: Bash scripting fundamentals How to write & execute scripts Variables and basic commands 💡 Why this matters? Shell scripting is the backbone of automation in Linux and DevOps environments. 📌 I’ve documented everything step-by-step in a beginner-friendly PDF. Comment “DAY1” and I’ll share it 👇 #DevOps #Linux #ShellScripting #Automation #Learning

Your automation worked fine. Until it ran on a different environment. Suddenly: Scripts failed due to permissions Files were not found Pipelines broke without clear errors Not because your tests were wrong, but because the environment was not understood. That is where most automation efforts struggle. 𝗟𝗶𝗻𝘂𝘅 𝗳𝗼𝗿 𝗧𝗲𝘀𝘁 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻 is designed to close that gap with a hands-on, workflow-driven approach. 𝗜𝗻 𝘁𝗵𝗶𝘀 𝗰𝗼𝘂𝗿𝘀𝗲, 𝘆𝗼𝘂 𝘄𝗶𝗹𝗹 𝗹𝗲𝗮𝗿𝗻 𝘁𝗼: • Work confidently with Linux commands, files, and permissions in real test environments • Automate routine tasks using shell and scripting basics • Set up and run Selenium tests within CI/CD pipelines on Linux The focus is on making Linux a practical part of your testing workflow.

🚀 Most Used Linux Commands Every Developer Should Know Backend, DevOps, AI… Linux isn’t optional anymore. Here’s your daily command-line toolkit 👇 📂 File Handling cd mkdir rm → Navigate, create, delete files & directories 📖 File Viewing cat less head tail → Read logs & inspect files quickly 🔍 Text Processing (Game Changer) grep awk sort find → Search, filter & manipulate data like a pro ⚙️ Process Management ps top kill pkill → Monitor & control running processes 🌐 Networking ssh scp → Connect & transfer files between servers 📊 System Monitoring df du free uname → Check disk, memory & system info 📦 Package Management apt dnf yum → Install & manage software 🔐 Permissions chmod chown → Control access & ownership 💡 Pro Tip: Don’t try to memorize everything. 👉 Think in actions: “I want to find a file” → find 👉 “Search inside files” → grep 💬 Which Linux command do you use the most?

Day ---11 Writing scripts is useful… But scripts become powerful when they can take input and make decisions. That’s what I explored today while learning about variables and conditions in Linux shell scripting. Instead of hardcoding everything, I practised how to make scripts dynamic and responsive. What I practised today: ✔ Creating variables in shell scripts ✔ Taking user input using read ✔ Using conditional statements (if, else) ✔ Comparing values inside scripts ✔ Making scripts behave differently based on input What stood out: This felt like a major upgrade from basic scripting. Now scripts are no longer just a list of commands; they can actually react and make decisions. Hands-on progress: ✔ Created scripts using variables ✔ Took input from the user ✔ Built simple decision-based logic ✔ Understood how conditions control execution flow Key takeaway 💡 Automation becomes powerful when it can adapt. This is where shell scripting starts becoming truly useful in real systems. #Linux #DevOps #ShellScripting #Automation #SystemAdministration #Infrastructure #TechLearning

One small script can save hours of repetitive work ⏳ This week, I’ve been revising Bash scripting to deepen my experience with Linux systems. So far, Linux has been about understanding the terminal: • Navigating files • Managing permissions • Running commands. Bash scripting feels like the point where those commands start working together. Instead of manually repeating the same steps, you can automate them to do tasks such as checking system status, creating files, searching logs, managing users, and much more. What’s cool is that it’s not just about saving time. It’s about building the mindset of automation, repeatability, and reliability - skills that sit right at the heart of DevOps and cloud engineering. Interested to hear from anyone who learnt bash after more typical programming languages 👇🏽 #bash #techcareers #coderco

🚀 Linux Commands Every Developer Should Know Mastering Linux isn’t optional anymore—it’s a core skill for developers, DevOps engineers, and backend builders. Here’s a quick breakdown of essential command categories: • Navigation & Filesystem → move and explore efficiently • File Operations → create, copy, delete with confidence • Permissions → control access like a pro • Process Management → monitor and kill processes • Networking → debug connectivity issues fast • Disk & Storage → manage system resources • Search & Text → powerful data filtering with grep/awk • User Management → handle users and groups securely 💡 Tip: Don’t just memorize—practice daily in your terminal. If you're building scalable systems, Linux is your foundation. #Linux #DevOps #BackendDevelopment #Programming #SoftwareEngineering #SysAdmin #TechSkills
