W9_L1: AWK programming part 1

Welcome to Week 9 Lecture 1 of the course "Introduction to the Linux Shell" by Gandham Phanikumar. Full Course: https://study.iitm.ac.in/es/course_pages/CS1102.html Video Overview In this lecture, you will unlock the power of the AWK programming language for text processing and data manipulation. The session provides a practical introduction to AWK, demonstrating how it can efficiently extract, transform, and analyze data directly from text files. You will learn about AWK’s record and field structure, its pattern–action execution model, and how to use built-in variables, operators, and functions for data processing. The lecture also highlights an example of data analysis that traditional spreadsheet software cannot perform, showing why AWK remains an essential tool for Linux and Unix users. By the end of this lecture, you will have the foundational skills to write your own AWK scripts and integrate them effectively into your command-line workflows.
