Linux basics session 1
We've set up the sandboxed environment (Virtual Machine) with Ubuntu Linux on our computer. We will use this for the rest of the course.
Recap:
- Overview of IT landscape in context of Linux OS
- Linux terminology
- Installation of VirtualBox - www.virtualbox.org (differs for Linux, Mac and Windows - see official instructions)
- Create a VM (name "testvm", type Linux - Ubuntu 64bit, 2GB RAM, 10 GB disk)
- Boot Ubuntu Desktop 20.04 Focal Fossa .iso image - ubuntu-20.04.1-desktop-amd64.iso from ftp.cvut.cz
- Install Ubuntu (language: english, machine name "testvm", username - your first name, password - something you can share with others, you may put your first name again for simplicity)
- Reboot VM and get to your very own testing Linux desktop environment.
- Finish start up wizard (we don't want anything extra)
- Install updates and reboot when asked
- Change screen resolution to fit your physical screen (right click on the desktop - display settings)
- Switch off testvm (from inside using the menu on top right)
Notes on issues we've encountered:
- some PC needs enabling virtualization in BIOS - superuser.com answer
- Mac with Catalina 10.15.6 needs to have audio disabled in the VM for .iso boot process to start - stackexchange.com answer
Self-study until the next session:
- Start your VM and log in
- Open a web browser and find a page with some text (~100 lines to copy)
- Open application called "text editor", paste text and save into a file
- Stretch goal: Open application called "terminal" and type following command (please spend time to learn how to write each character on your keyboard - this will become essential; hint: the strange looking apostrophe is a "back tick" - wikipedia).
