Linux in a nutshell

This course gives a general introduction to Linux, a first acquaintance with the possibilities of the system, and some basic commands to start with.

The course only treats the user aspects of the operating system, not the system aspects. A description of the file system, the processes and the shell, should prepare the user for using the basic Linux command set. Part of the course is dedicated to discussion of the most important security aspects.


Il n'y a pas de sessions publiques à ce moment. Nous organisons volontiers un cours en entreprise ou une session publique supplémentaire (en cas d'un nombre suffisant de participants). Intéressé? Veuillez contacter ABIS.
