Build a strong foundation in Unix input/output, file management, and system administration with this hands-on course focused on essential operating system concepts and command-line workflows. You will learn how Unix handles input and output, work with file streams and redirection, and use sed and regular expressions to manipulate text efficiently.

As you progress, you will explore the Unix filesystem hierarchy, navigate directory structures, perform device mounting and unmounting operations, and manage users, groups, and file permissions. Through practical command-line activities, real-world scenarios, and graded assessments, you will strengthen your understanding of both core Unix concepts and system administration tasks. This course is ideal for learners who want to develop practical Unix administration skills or deepen their understanding of operating system fundamentals. By the end of the course, you will be able to analyze Unix input/output behavior, implement file and text management techniques, navigate and maintain Unix file systems, and administer user access and permissions with confidence. What makes this course unique is its progression from foundational input/output concepts to essential system administration practices, helping you connect core Unix principles with practical administrative operations in a structured learning experience.
