It builds solid knowledge of Linux fundamentals, the most important commands, and initial system administration experience — with hands-on exercises on real STACKIT Linux VMs rather than a purely theoretical rundown. Across seven modules it moves from Linux's origins and distributions through CLI basics (navigation, file management, editors), users and permissions, everyday system administration (processes, monitoring, packages), networking and security concepts, and finally troubleshooting: log analysis, backups, and error diagnosis. ### What You'll Learn - Explain the basic concepts and origins of Linux - Confidently work with the most important Linux commands for navigation, file management, and user management - Understand and use the Linux filesystem structure - Apply basic network commands and system administration processes - Practice on a STACKIT Linux VM to apply the knowledge in a real environment - Perform troubleshooting and basic maintenance on a Linux system ### Modules - Introduction - Distros & VMs - CLI Basics - Users & Permissions - System Administration - Networking & Security - Troubleshooting
