There are certification courses for Unix

Why Linux

In the meantime there is hardly an area in which Linux is not found: Be it on the cell phone or in home automation, in medical devices or supercomputers from search engine operators and weather researchers.

Linux is just everywhere. And there are good reasons for this:

  • excellent stability
  • no / low cost
  • open source
  • adaptability
  • an almost infinite range of software

to name just a few.

History of Linux

Linux has its roots far back. In 1969 Ken Thompson and Dennis Ritchie developed the forerunner Unix. Unix was soon the dominant basis for mainframe systems and workstations. However, the commercial Unix had one major disadvantage:

  • it was not freely available (free in the sense of free) and very expensive to buy.

Annoyed by this circumstance, the then 21 year old Linus Torvalds set out to develop a free Unix in 1991: Linux was born! Together with Richard Stallman's existing software collection of the GNU project, it was now possible to install a Unix compatible operating system on IBM compatible computers.


Initially ridiculed and ignored, later hated and fought. Nowadays it runs on at least 90% of all home electronics devices, PCs and servers. If you are reading these lines, you are reading the text that our web server delivered to you. And that runs on Linux too.


Linux isn't just for nerds. There is a huge range of software for every imaginable use case. In order not to get lost in the sheer oversupply and to master the most important basics, we have made it our task to optimally prepare you for Linux.

Linux course modules

Our course modules are self-contained learning content. This means: we have done our best to ensure that you can complete the courses in the order you want. However, some courses require a certain basic knowledge. We have noted this information for each module.

After each module you can optionally take an exam. There is a bilcom course module certificate for this.

We would be happy to advise you on the selection of modules in order to optimally design your course for you.

Help, that's too complicated for me, or: Linux Complete

If the compilation of the modules seems too complex to you, we have a solution for you:

  • We have combined modules that go particularly well together into courses.
  • We have made a selection of modules to give you a simple overview.


Due to our wien-cert certification, there are numerous opportunities to receive funding for a bilcom course. We have summarized the most important things:

We would be happy to advise you personally.

Loan devices

You want to deepen your knowledge at home but your notebook is too old? No problem: we have sufficient rental equipment available that we can make available to you during your course at bilcom.

Are there any requirements for the courses?

We recommend basic computer knowledge for all courses. Our “EDV for Beginners” course provides an ideal basis for this. If you are unsure how good you are already: We would be happy to check your knowledge in a joint conversation.

I would like more information on Linux

With pleasure. Here is a small, entertaining list of additional information:

Module - Linux Practice: Security, Tele-Banking, Spam and Viruses

Vulnerabilities, spam and total cost billions of euros each year. Our practical seminar shows you how you can carry out sensitive tasks on a secure system.

  • Checking the hardware for changes and abnormalities (keyloggers, dongles, cameras, microphones)
  • Verifying the Linux sources
  • Linux installation on a USB stick
  • Check network security (WiFi encryption, https)
  • Keep passwords safe across multiple devices using encryption and the cloud
  • Detect and avoid phishing and spam effectively
  • Viruses, worms and trojans

Module - Linux: History, Dates, Facts & Curiosities

  • What is Linux anyway? what is a kernel? And what does all of this have to do with particle accelerators, Android and rockets?
  • Unexpected and surprising areas of application (kitchen machines, cars, nuclear power plants, milking machines)
  • What is open source and why is it important? (gpl / agpl / 2/3, cc, mit, gnu)
  • Large (deliberate) security gaps and fraud in the closed source (Microsoft, Cisco, Intel)
  • Definition of free: free speech and free beer
  • Distributions and their differences & use cases (Debian / Ubuntu / Linux mint, Suse / Opensuse, Redhat / Fedora, Arch)

Module - Linux practice: the right installation

  • Installation (using the example of Linux mint, in VMware)
  • Network basics (what is an IP? What is a Mac? My IP internal / external)
  • Software installation and deinstallation via the graphical user interface (package manager)
  • Configure in the graphical user interface
  • Desktop systems, similarities and differences between gnome, kde and lxce

Module - Linux practice: selected user programs

  • Office solutions for documents, presentations and spreadsheets (Open Office, Libre Office, gnu)
  • Safe in the www with the web browser (Firefox, Chrome)
  • View and edit images with Nautilus and Gimp
  • Manage, listen to and edit sounds and music
  • View, convert, edit and trim videos
  • Text editors (gedit, kate, vsc)

A bonus with this mini Linux course: Free USB stick with the finished Linux on it for at home
