Linux/UNIX fundamentals

This course gives a general introduction to UNIX and to Linux. It applies to all UNIX variants (AIX, Solaris, HP-UX, ...) and all Linux distributions (Red Hat, Fedora, Debian, Ubuntu, zLinux, ...).

The course mainly treats the user aspects of the operating system, not so much the system aspects. In addition to basic topics like the file system and the shell, and conceptual similarities and differences with other operating systems, it mainly focuses on the basic UNIX command set. Part of the course is dedicated to a sufficiently in-depth treatment of the vi editor. An important amount of time is spent on practical exercises.


No public sessions are currently scheduled. We will be pleased to set up an on-site course or to schedule an extra public session (in case of a sufficient number of candidates). Interested? Please contact ABIS.

Intended for

All potential users of UNIX or Linux, whether end-user, analyst, application developer or administrator.


Some general knowledge of computing principles is required. No UNIX or Linux background is necessary. Knowledge of a different operating system or of a programming language could be an advantage but is not needed.

Eén van de betere cursussen die ik gevolgd heb.

Voldeed aan verwachtingen aangezien reeds summiere kennis van Linux. Deze cursus zorgde voor de nodige verklaring& diepgang van fundamentele begrippen, werking,commando's... etc. Resultaat:veel beter begrip,begrijpen wat men heeft gekopieerd of gegoogled

Very good, the documentation is clear and the instructor is very knowledgeable

Very well instructed, only remark to make is to include just a bit more practical examples

  (, )

It was a very good course with a lot of additional nuggets of knowledge provided by our teacher

  (, )

Good, 7 hours of Linux is a lot for 5 days in a row but content was certainly qualitative
