Linux Master

Linux Master — Learn the Command Line, Properly

41 lessons across 10 modules take you from your first shell prompt to real
system administration — permissions, processes, package management,
networking, scripting, storage, and troubleshooting. No Linux machine
required: everything is explained, quizzed and practiced right in the app.

WHAT'S INSIDE
• Shell Fundamentals — navigating, editing, and the shell itself
• Files, Permissions & Ownership — chmod, chown, sudo, special bits
• Processes, Jobs & Services — what's running, signals, background jobs
• Package Management — apt, dnf/rpm, repositories and broken states
• Networking from the Command Line — interfaces, DNS, ports, SSH
• Storage & Filesystems
• Text Processing & Pipes
• Shell Scripting
• Troubleshooting & Performance
• Users, Groups & Hardening

HANDS-ON LABS
7 guided labs walk you through real tasks on your own Linux system —
described step by step, with the reasoning behind each command explained,
not just the syntax to memorize.

COMMAND REFERENCE
A searchable reference for the commands covered, for when you just need a
quick reminder mid-task.

QUIZZES & PROGRESS
Every lesson ends with a quiz. Track your progress with XP, levels, a daily
streak, and badges — all stored on your device.

100% OFFLINE
Every lesson, lab and quiz is bundled with the app. No internet connection
needed once installed, and nothing about your learning is ever uploaded.
