Module 8: Basic Shell Scripting & Automation
Shell scripting is where administration stops being manual. This module teaches practical bash scripting for real system administration tasks — not theoretical programming. You’ll start with script structure, variable handling, and debugging, then move into control structures: conditionals, loops, and functions.
The emphasis throughout is on scripts that handle errors gracefully and give useful feedback. Text processing gets a full section — combining grep, sed, and awk within scripts to analyse logs, process configuration files, and generate reports.
The hands-on development component focuses on creating practical automation solutions for common system administration tasks. You’ll build backup scripts, log analysis tools, system health checkers, and maintenance automation. Security considerations receive appropriate attention as poorly written scripts can create significant security vulnerabilities. Advanced automation concepts prepare you for infrastructure-as-code approaches increasingly common in modern IT environments.
