Master Bash, Regex, and Automation to build real-world monitoring tools, data pipelines, and log analysis scripts.

What you’ll learn
– Process, filter, and transform text data from files and command outputs using essential tools like grep, awk, and sed.
– Master Regular Expressions (Regex) to perform precise pattern matching for advanced data extraction and validation, such as finding specific log entries or IP a
– Build a real-world, continuous monitoring script that checks system resources (like RAM), generates reports, and triggers alerts based on custom thresholds.
– Handle signals (Ctrl+C, kill) within a script using trap to perform graceful shutdowns and ensure critical cleanup operations are always completed.
– Automate the execution of scripts by scheduling them as recurring tasks with cron, the standard Linux job scheduler.
– Create simple, multi-system networking pipelines using netcat to build custom ETL (Extract, Transform, Load) and data masking tools.
– Programmatically check for the success or failure of any command by analyzing its exit code ($?), enabling robust error handling in your scripts.

Requirements
– No prior programming or scripting experience is required; all concepts are taught from the ground up.

Description
You will learn to think like a scriptwriter, breaking down complex problems into a sequence of commands. We dive deep into the tools that power all serious scripting: grep, awk, and sed, paired with the incredible precision of Regular Expressions (Regex) to slice, dice, and transform any text data you encounter. Instead of just learning what a for loop is, you’ll use one to read a system log file line-by-line to find security threats. Instead of just defining a function, you’ll use one with the trap command to ensure your script shuts down gracefully and securely, even when interrupted.

Through hands-on projects, you will:

Build a complete system memory monitor that runs continuously, logs usage to a report, and sounds an alarm when it crosses a critical threshold.

Write a log analysis tool that hunts for failed login attempts and other security events in system logs.

Construct a simple, multi-machine ETL pipeline using netcat to filter and even mask sensitive data as it flows across a network.

By the end of this course, you won’t just "know" shell scripting; you will have the practical skills and the problem-solving mindset to automate your workflow, build your own tools, and tackle complex system administration tasks with confidence.

Who this course is for:
– IT Professionals and System Administrators who want to automate repetitive tasks like monitoring, user management, and log analysis.
– DevOps Engineers who need to master shell scripting as a foundational skill for building CI/CD pipelines and automating infrastructure.
– Aspiring Cybersecurity Analysts and Pentesters who need to understand how to parse logs, search for security events, and write custom tools.
– Developers (Python, Java, etc.) who want to expand their skill set to include the command-line automation necessary for their development and deployment workflows.
– Data Engineers and Analysts who need to perform initial data filtering, transformation, and processing at the command-line level.
– Computer Science students looking for a practical, hands-on course to supplement theoretical knowledge with real-world scripting projects.
– Anyone who works with a command line and wants to become dramatically more efficient and powerful in their day-to-day work.
