W9_L2: AWK programming part 2

Welcome to Week 9 Lecture 2 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 explore the power and flexibility of arrays and loops in the awk programming language. The session focuses on associative arrays (hashes), explaining how to assign values, iterate through indices, and delete elements efficiently. You will also learn about different types of loops in awk, including index-based and C-style for loops, if statements, and while loops, along with their practical uses. The lecture demonstrates how to apply these concepts in real-world scenarios such as processing complex text files, analyzing web server logs to identify suspicious activity, and generating usage statistics. Finally, you will see how to combine awk with other command-line tools to perform powerful text analysis and automation tasks, enhancing your Linux scripting toolkit.
