Operating System Fundamentals with Bash Scripting

Have you ever wondered what actually happens behind the scenes when your code runs, or how software communicates with your computer's hardware? Understanding the core mechanics of operating systems is the key to writing efficient, secure, and highly optimized applications. This course bridges the gap between system concepts and practical automation, giving you a clear mental model of computing architecture. You will gain a deep understanding of process management, memory allocation, and file systems, and immediately apply this knowledge by writing robust Bash scripts to automate daily tasks. What you will learn: - Understand core operating system architectures, kernel space, and user space. - Manage system processes, job control, and signal handling via the command line. - Navigate and manipulate the hierarchical file system and permissions model. - Write automated Bash scripts using variables, loops, conditional logic, and modern error-handling techniques. - Monitor system resources, memory usage, and CPU performance using terminal tools. - Practice safe script development with robust input validation and clean exit codes. We begin with foundational definitions, demystifying the kernel, system calls, and physical resource management. From there, you will transition into the terminal, learning how to command the system and automate workflows step-by-step through clear, text-based explanations and practical scripting exercises. This course is designed specifically for beginners, software developers, and aspiring system administrators with no prior operating system or command-line experience.
