Linux System Fundamentals Training in Greece

Many organizations are increasingly integrating Linux systems into their existing IT infrastructure. This may be to provide developers with their preferred platform, introduce alternative network server solutions, or enhance overall security architecture.

Linux and Unix systems are also widely used within virtualized environments such as VMware, Xen, KVM, or VPC. These technologies enable multiple operating systems to run on a single workstation or server.

This course is designed to give participants a strong foundation in Linux and Unix environments. It combines both user-level and administrative tasks, allowing learners to understand how Linux systems operate while gaining practical experience with command-line tools and system management tasks.

The training introduces key Linux concepts including filesystem navigation, Bash shell usage, process management, and basic system administration.

No prior Linux knowledge is required. However, participants should ideally have:

• Basic understanding of modern operating systems

• Familiarity with command-line interfaces

• General IT or computing experience

After completing this course, participants will be able to:

• Work effectively with the Linux Bash shell

• Navigate the Linux filesystem and manage files and directories

• Understand the client-server architecture of the X Window System

• Edit files using vi, vim, or graphical editors

• Process data using filter tools
