Everything on Linux — every server you'll harden, every container you'll ship, every log you'll read — sits on top of a handful of fundamentals. This is where you build them. The Basics track is a deliberate ladder: understand how the shell reads a command, learn to identify the disks under your mounts, see exactly what hardware the kernel exposes, and capture what's on screen without reaching for a mouse. No hand-waving, no "just trust me" — every command comes with the output you should expect and the reasoning behind it. Start here and the rest of Linuxier stops feeling like magic and starts feeling like muscle memory.
Start at the prompt: the essential navigation commands, reading file listings and permissions, and the small customizations that make the terminal feel like home.
