UNIX File Systems and Persistent Storage Management

Managing data reliably is at the heart of system administration and software development. To build stable applications or maintain secure servers, you must understand how UNIX structures, stores, and protects data on disk. This course provides a clear, conceptual foundation of UNIX file systems, moving from basic terminal navigation to advanced storage management concepts. You will start by learning essential terminology, directory hierarchies, and core storage principles before diving into practical configuration. What you will learn: Understand UNIX file system architecture, including inodes, blocks, and metadata structures; Manage file permissions, ownership, and access control lists to secure sensitive data; Execute system calls and command-line utilities for efficient file manipulation; Configure persistent storage, mount points, and partition tables; Apply modern storage concepts, including logical volume management and virtual file systems; Troubleshoot common disk space, permission, and file corruption issues. The curriculum is structured to guide you from foundational definitions to practical command-line scenarios, ensuring you build confidence with real-world administration tasks. This course is designed specifically for beginners, system administrators, and developers looking to solidify their infrastructure knowledge, with no prior UNIX experience required.
