Mastering Shell Scripting From Basics to Automation

Master Bash, Regex, and Automation to build real-world monitoring tools, data pipelines, and log analysis scripts.
What you'll learn
Write powerful shell scripts using core Bash syntax, including variables, loops (for, while), and conditional logic (if-else).
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
Have you ever wanted to move beyond just typing commands and start telling your computer exactly what to do, automatically? This course is your hands-on journey to mastering shell scripting, transforming you from a command-line user into a powerful automator. We will build your skills from the ground up, starting with the absolute basics of variables and logic and progressing to building sophisticated, real-world projects that solve genuine IT challenges. This is not a dry, theoretical course; you will be writing practical scripts from the very first sections.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
