Learn Linux basics & practise right away
Anyone who wants to master Linux starts at the command line. Instead of memorising theory, you practise directly on a real cloud VM here: you type the commands, see the result immediately and get automatic feedback on whether it's right.
Navigate the file system
pwd shows where you are, ls lists a directory's contents, and cd changes folders. These three commands are the foundation – almost every task starts with orienting yourself in the system.
Create files and directories
Use mkdir for folders, touch for empty files, cp and mv to copy and move, rm to delete. On a real VM you also learn the consequences – nothing is more dangerous and instructive than a real terminal.
Install packages
You install software via the package manager (e.g. apt). Understanding how packages, updates and dependencies fit together is the basis for everything else – from web server to hardening.
