Unix Performance, Signals, and System Internals

This course provides a structured and practice-oriented journey into the internal workings and performance dynamics of the Unix operating system. Through two comprehensive modules, learners will explore and analyze key system components including CPU time states, signal handling, logging mechanisms, interrupts, traps, and environment variables. They will also configure and manipulate file systems, directories, and essential Unix utilities for effective system operation. Beginning with foundational performance analysis and process signaling, students will interpret system behaviors, configure runtime environments, and control process interaction. The second module advances into practical command-line operations where learners apply skills to manage files, schedule tasks, and profile system activities. The course culminates with a complete review that synthesizes all prior learning into actionable, real-world system administration capabilities. Designed with Bloom’s Taxonomy in mind, learners will identify, differentiate, configure, analyze, and ultimately apply Unix system principles to manage and troubleshoot real-time Unix environments with confidence
