Module 2: File System Management
File system management forms the backbone of Linux system administration. This module provides you with coverage of navigation, organization, and file manipulation skills essential for daily system administration tasks. You’ll begin with the Filesystem Hierarchy Standard (FHS) and learn the logic behind Linux’s directory structure. This knowledge proves invaluable for troubleshooting since you must locate configuration files, logs, or executables quickly.
The module progresses through essential file operations and teaches you to work efficiently with files and directories. You’ll master pattern matching with glob expressions, recursive operations, and the powerful find command. These efficiency techniques help you develop the speed and confidence needed for daily system administration tasks while avoiding common mistakes that can impact system reliability.
Permission management receives extensive coverage as this concept is fundamental to Linux security and system organization. You’ll learn both numeric and symbolic permission notation, practice with special permissions like setuid and sticky bit, and understand how ownership relates to access control. Real-world scenarios help you apply permission concepts to practical situations including shared directories and security troubleshooting.
Text processing skills are introduced as essential tools for system administrators who regularly analyze log files and process configuration data. You’ll learn grep for pattern matching, sed for basic text manipulation, and awk for structured data processing. These skills prove fundamental for log analysis and system monitoring tasks that you’ll encounter in production environments.
The module concludes with file archiving and compression techniques for backup management and file transfers. You’ll master tar command operations, understand different compression formats (gzip, bzip2, xz), and practice creating automated archiving solutions. These skills support backup procedures, system migrations, and file distribution tasks essential for maintaining production systems.
