Algemeen :

The Linux/UNIX Fundamentals training is the ideal starting point for anyone who wants to get hands-on with Linux-based systems. Developed by the open-source experts at AT Computing and exclusively available via Vijfhart, this course provides a practical introduction to the world of Linux. GNU/Linux is a powerful and versatile operating system that forms the foundation of servers, cloud environments, and modern technologies worldwide. A large part of the internet runs on Linux, and your smart vacuum cleaner, Android device, or even your car probably can’t do without it. As open-source software, Linux is continuously improved by a global community of developers, making it reliable, secure, and efficient. Step by step, you learn how this powerful system works and why it is so well-suited for servers, automation, containers, cloud environments, and modern applications.



The course begins with an introduction to Linux and UNIX, their history, variations, and the role of the kernel. You learn how the terminal and different shells work and start practicing with basic commands such as echo, date, and who. From there, you move on to essential and advanced file management—creating, viewing, copying, renaming, deleting, and organizing files and directories. You also work with regular expressions and grep, study filename expansion, and learn how to use the vi editor to edit text files.



The course also covers I/O redirection and pipes, showing how to combine commands into powerful workflows. You explore process management (ps, top, kill, nice), shell variables, and simple scripts. You also look into filesystem management, disk usage, search commands, and working with links. Filters such as sort, uniq, cut, wc, and tr are covered, as well as file comparison tools like diff and cmp. Finally, you focus on permissions, user management, and essential networking tools such as remote login (ssh), secure copy (scp), and rsync. Step by step, you build a solid foundation in Linux and UNIX.



Throughout the course, you complete hands-on exercises in a practical lab environment. You practice using commands in the shell and write your first scripts, immediately putting theory into practice. You learn how to combine commands efficiently, manage user permissions, and use networking tools effectively. This way, you develop directly applicable skills that are valuable for system administration and workflow automation on Linux-based systems.



This course is guaranteed to run.

Doel :

By the end of the course, you can work confidently with the command line, manage files, set permissions, and install software. You have mastered the fundamentals of Linux and UNIX, giving you a strong foundation to grow further toward system administration, cloud engineering, or security.
