Linux/UNIX – Basic course

Linux/UNIX – Basic course

Course Summary

In this course, you will learn how Linux is structured and how it works from a user perspective. The course describes Linux in general, and is suitable regardless of which Linux variant you use.
The course briefly covers the historical connection between Linux and UNIX.
Many comparisons are made to how it works in Windows and MacOS.  

  • What a Linux system is and how to use it
  • Linux architecture and underlying processes
  • The differences between different Linux distributions and UNIX.
  • Use the basic commands found in Linux systems.

The training is aimed at people who want a quick and clear introduction to the Linux operating system. This includes anyone who is generally interested in Linux, who is going to use Linux or as a first step for those who will administer Linux systems. The focus is on learning how to manage Linux systems via the command line

The course assumes that you have used Windows or MacOS before taking the course. You do not need to have used the command line, written scripts or worked with Linux before. However, the course also works well for those who already have some experience of Linux and programming – you will then be able to deepen your knowledge.

This course has no certification.
