Shell Scripting

Killercoda lab progress 0/4 completed

Interactive labs, not module completion

Automating Linux tasks with Bash.

Overview

Shell scripting transforms repetitive manual tasks into reliable automation. This section teaches Bash fundamentals, text processing, and practical scripting patterns used in DevOps and Kubernetes operations.

Modules

#	Module	Description	Time
7.1	Module 7.1: Bash Fundamentals	Variables, conditionals, loops, functions	90–120 min
7.2	Module 7.2: Text Processing	grep, sed, awk, jq for data manipulation	70–100 min
7.3	Module 7.3: Practical Scripts	Common patterns, error handling, logging	90–120 min
7.4	Module 7.4: DevOps Automation	kubectl scripts, CI/CD helpers, operational tools	70–100 min

These are planning estimates copied from the four module headers, not measured learner completion times. Their arithmetic gives an aggregate range of 320–440 minutes (about 5 hours 20 minutes–7 hours 20 minutes); individual setup, reading, and practice time will vary.

Why This Section Matters

DevOps and SRE work involves constant automation:

Operational tasks — Health checks, backups, deployments
Data processing — Log analysis, report generation
Kubernetes management — kubectl wrappers, cluster operations
CI/CD pipelines — Build scripts, deployment automation

The shell is the universal interface to Linux systems.

Prerequisites

System Essentials — Basic Linux commands
Troubleshooting — Commands you’ll want to automate
