Input Output, Expression Handling, and System Management

Build practical Unix skills by mastering input/output, file management, and core system administration through a structured command-line learning experience. Designed for learners seeking Unix administration skills or a deeper understanding of operating system fundamentals, this course connects essential concepts with practical administrative tasks. You’ll examine how Unix handles standard input, output, and error through file streams and redirection. You’ll use sed and regular expressions to manipulate and substitute text, explore the Unix filesystem hierarchy, and navigate standard directories. You’ll also execute commands to mount, unmount, and inspect storage devices and file systems, then manage users, groups, file permissions, and system access. By the end of the course, you’ll be able to analyze Unix input/output behavior, implement file and text management techniques, maintain Unix file systems, and administer access permissions. What makes this course distinctive is its focused progression from foundational I/O concepts to system-level administration, supported by practical command-line activities, real-world scenarios, and graded assessments. Enroll to develop an organized, applicable foundation in Unix command-line workflows and operating system administration.
