This course equips learners with the essential skills to analyze, configure, and apply Unix file permission models and shell environment settings with confidence. Starting from foundational concepts like symbolic and numeric permission representations, learners will explore user and group ownership management, special permission bits such as SUID, SGID, and Sticky Bit, and their impact on system security and accessibility. The course then transitions into Unix environment configuration, where learners will learn to define, export, and manage environment variables and startup profiles across both user and system levels.

By the end of this course, learners will be able to interpret complex permission strings, modify access controls appropriately, and optimize the Unix environment for streamlined command execution and secure multi-user interactions. The course is ideal for aspiring system administrators, developers, and IT professionals seeking practical Unix competency for real-world applications.

This course equips learners with the essential skills to apply, analyze, and configure Unix-based file utilities and command-line operations. Designed for beginners and intermediate users, it delves into practical system tasks such as printing, piping, filtering, mailing, navigating directories, and managing environment variables. Through structured lessons, learners will explore core Unix tools (pr, lpr, mail, grep, more, etc.), understand absolute vs. relative path handling, and modify permissions using symbolic and numeric modes. Each module fosters command proficiency through interactive learning objectives rooted in Bloom’s Taxonomy—culminating in the ability to execute real-world Unix operations confidently and effectively.

This course provides an in-depth exploration of networking fundamentals, network protocols, and file management within Unix-based systems. Designed for learners aiming to gain a thorough understanding of how Unix systems communicate over networks, this course covers key topics such as IP addressing, various networking protocols (TCP/IP, HTTP, FTP, DNS), network troubleshooting, and security. Students will learn how to configure network settings, use command-line tools to troubleshoot network issues, and apply knowledge of network layers and protocols. The course will enable learners to define, explain, analyze, and compare networking concepts, while gaining practical skills necessary to navigate and manage Unix-based networks efficiently.

The course uses Bloom's Taxonomy to help learners move from foundational knowledge to higher-level thinking, ensuring mastery of both theoretical concepts and practical applications in networking and protocols. Through a mix of theory, demonstrations, and hands-on practice, learners will be equipped to address real-world networking challenges in Unix environments.

This course is a comprehensive introduction to shell programming and Unix automation, designed for learners who want to build a strong foundation in system-level scripting. Using the Bash shell as the primary environment, the course guides learners through the step-by-step progression from basic command-line interactions to advanced scripting constructs.

Through carefully structured modules and practical assessments, students will identify key Unix and shell programming concepts, demonstrate scripting techniques, and construct effective automation solutions. Emphasis is placed on applying, analyzing, and evaluating shell commands, scripting syntax, variable management, control flow logic, file testing, and I/O redirection to real-world use cases. By the end of the course, learners will be able to develop full-featured shell scripts that streamline system tasks, perform condition-based logic, handle user inputs and arguments, and operate across diverse Unix-based environments with confidence and clarity.

This hands-on course is designed to enable learners to apply, analyze, and optimize Unix shell techniques for effective command-line operations. Through structured modules and real-world scripting examples, participants will explore command chaining, variable handling, and stream manipulation using core tools like xargs, grep, and awk.

Learners will also gain the ability to navigate built-in Unix help systems and construct modular, reusable shell functions for advanced task automation. Whether creating efficient pipelines or debugging scripts, students will develop the confidence and technical proficiency to evaluate and synthesize Unix command strategies for professional and automation use cases. This course is ideal for developers, data engineers, system administrators, and anyone seeking to deepen their practical Unix command-line skills with a focus on clarity, efficiency, and best practices.
