W7_L1: Bash scripts - part 2a

Welcome to Week 7 Lecture 1 Part 2a 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 dive deeper into bash scripting and learn advanced techniques to enhance your shell programming skills. The session begins with debugging methods using the -x option to trace script execution and continues with combining test conditions in loops using logical operators like && and ||. You will explore different approaches for performing arithmetic operations, including integer math and floating-point calculations with the bc command. The lecture also introduces “here docs” for handling multi-line input efficiently and demonstrates how to inspect and modify the PATH environment variable for better command accessibility. Practical examples throughout the session will help you apply these concepts, modify existing code, and adapt them to your own Linux projects.
