📚 Course Title: Understanding The Internals Of The Unix Kernel Architecture

Headline: Mastering the Unix Operating System

Course Description:

Embark on a deep dive into the world of Unix Operating Systems with our comprehensive online course, "Understanding the Internals of Unix Kernel Architecture". This course is meticulously crafted by Satish Venkatesh, a seasoned software engineer who has conquered interviews across 16 software giants.

Why This Course?

Life's unpredictability often demands immediate action. In such critical moments, it's crucial to have the knowledge and skills to take control. Remember, we all leave this world with only our experiences and memories. Let's ensure those are ones that make us proud and fill us with a sense of accomplishment, even years down the line.

This course is designed to equip you with a robust understanding of the Unix kernel, specifically focusing on its three major subsystems:

1. 📁 The File Management Subsystem

   • Internal file representation and management

2. 🚀 The Process Management Subsystem

   • Process structure and control calls

3. 💬 Inter-process Communication (IPC)

   • Signals, pipes, message queues, and shared memory

Course Highlights:

• In-depth Algorithm Explanation: We demystify the algorithms behind crucial system calls within the Unix operating system.
• Hands-on Learning: With a strong belief in learning by doing, this course offers a series of practical assignments that will solidify your understanding of the kernel's internals.
• Real-world Applications: You'll apply your knowledge by writing your own C programs to replicate various Unix commands and utilities, such as ls, cp, stat, and many more.

Assignments:

Throughout the course, you will complete assignments that cover a range of practical applications, including but not limited to:

• Memory Management: Implement your own malloc, free, and realloc library functions in C.
• File System Commands: Develop programs for ls, cp, stat, tee, size, and touch commands, as well as custom file operations like fopen, fread, fwrite calls.
• System Utilities: Create sample state machines, implement a shell, demonstrate the functionality of daemons, and more.
• Inter-process Communication: Write programs using FIFOs, pipes, message queues with semaphores, shared memory with semaphores, and client-server models.

Course Structure:

• Comprehensive Course Overview: This course focuses on the internals of Unix OS, specifically the algorithms driving its system calls. We will not be covering the command-line usage of Unix/Linux OS but will provide sample code flows to illustrate the system call algorithms.

Who Should Take This Course?

This course is perfect for:

• Aspiring software engineers and developers looking to deepen their understanding of operating systems, particularly Unix.
• IT professionals aiming to expand their knowledge base and improve their system programming skills.
• Anyone curious about the inner workings of Unix and how it influences Linux and other contemporary operating systems.

Enrollment Details:

If you're ready to embark on this journey of understanding the Unix kernel architecture, please enroll in the course. Dive into the world of system programming and master the algorithms that make Unix such a robust and reliable operating system.

👩‍💻 Note: This course is not about learning command-line operations in Unix/Linux. Instead, it provides an in-depth exploration of the kernel's internals by mapping out the flow of code for system call algorithms.
