Sed and Awk Foundations with Regular Expressions

In the world of data processing and system administration, the ability to parse, filter, and transform text efficiently is an invaluable superpower. This text-based course guides you from the fundamental concepts of text manipulation to writing confident command-line scripts. You will start by mastering the syntax of regular expressions, the essential building blocks for pattern matching, before diving into the practical mechanics of Sed and Awk. Through clear explanations and structured exercises, you will transition from manual text editing to automated, stream-based processing. You will learn to handle file transformations, extract specific data fields, and write clean, maintainable scripts for daily tasks. What you'll learn: - Understand the core principles of regular expressions and how to construct pattern-matching rules - Apply Sed commands for efficient line-by-line text editing, substitution, and filtering - Use Awk to parse structured data files, generate reports, and perform calculations - Combine regular expressions with command-line tools to automate complex search-and-replace workflows - Write clean, readable scripts and integrate modern shell scripting best practices - Debug and optimize your text-processing pipelines for speed and reliability This course begins with essential terminology, regular expression syntax, and foundational stream concepts. It then moves into hands-on examples of Sed and Awk in action, demonstrating how to solve real-world text manipulation challenges. This course is designed for beginners, system administrators, developers, and data enthusiasts who want to automate their text workflows. No prior experience with Sed, Awk, or regular expressions is required. Start your journey to command-line efficiency and master text processing today.
