Technical requirements

For these recipes, we're going to use two Linux machines – in our case, it's going to be two VMware virtual machines with Ubuntu (20.04 Focal Fossa). Let's call them cli1 and gui1, and as the book progresses, we're going to add some more, as our topics grow in complexity. So, all in all, we need the following:

• VMware Player, Workstation, Fusion, or ESXi
• Ubuntu 20.04 Focal Fossa installation ISO file
• A bit of time to install these two virtual machines without the GUI (the cli1 machine) and with the GUI (gui1)

After the installation process is finished, we're going to start with shell basics – our very next topic.
