Advanced Text Processing and System Management

Overview

This lab focuses on advanced text-processing and system-management techniques using Linux command-line utilities like grep, sed, and awk. Participants will also learn process-management commands (ps, pgrep, kill) and Bash scripting to automate service monitoring, log analysis, and directory backups. Designed for individuals with basic Linux experience, this lab empowers learners to streamline text and system administration tasks efficiently.

Inside this Lab

Through hands-on exercises, you will:

Learn pattern matching and filtering through the grep command.
Perform text transformations with sed and conditional text extraction using awk.
Manage system processes using ps, pgrep, kill, and pkill commands.
Create Bash scripts for service monitoring and log file analysis.
Automate directory backups with tar using shell scripting.
Combine commands with pipelines to solve real-world log analysis and error detection tasks.

By completing the lab, participants will gain practical DevOps skills with Linux tools, including how to automate repetitive tasks and ensure system reliability.
