[eYRC 2026-27]: Introduction to Linux

Ever wondered why almost every server, supercomputer, cloud platform, and embedded device runs Linux? What makes a simple black terminal so powerful that developers, system administrators, and cybersecurity professionals rely on it every day? This session takes you on an engaging journey into the world of Linux—exploring how the operating system is structured, how the file system keeps everything organized, and how the Bash shell serves as the powerful interface between users and the operating system. You’ll discover how a few simple Bash commands can navigate entire file systems, manipulate files with ease, and automate repetitive tasks through shell scripting. We’ll also uncover how tools like cron quietly schedule and execute critical jobs that keep production systems running behind the scenes. Through real-world examples and live demonstrations, you’ll see why Linux and Bash form the backbone of modern software development, DevOps, cloud computing, cybersecurity, and embedded systems. No prior experience is required—just curiosity to discover what happens behind the scenes every time you open a terminal. By the end of the session, you’ll not only understand the core concepts of Linux but also gain a new appreciation for the command line as one of the most powerful interfaces in modern computing.
