Linux Command Master

◆ Learn Linux by "Typing" Commands: A Linux Learning RPG ◆

Linux Command Master is a retro RPG-style learning app where you progress through stages by actually typing Linux commands.

Instead of just passively viewing information, this game allows you to repeatedly answer questions by typing commands as if you were using a real machine. This helps you not only acquire LINUC/LPIC certifications but also learn the operations necessary for real-world work through hands-on practice on your smartphone.

■ Recommended for:
・Those aiming to acquire LINUC/LPIC certifications
・Engineers who want to learn Linux commands in a practical way
・Those who want to learn steadily in their spare time
・Those interested in Linux servers but who can't learn from books

■ App Features
【Answer by Actually Typing Commands】
Instead of multiple-choice questions, you freely input commands just like on a real machine.
The judgment engine handles differences in option order and long/short notation, so you'll get the correct answer if you type as you've learned.

【Stage Progression in a Sugoroku Format】
Each stage consists of 20 squares, and your avatar moves one step at a time. There are regular squares, bonus squares (double XP), review squares, and boss squares, ensuring you can enjoy the game without getting bored.


[Automatic Review of Incorrect Answers]
Incorrect answers are recorded in the history and prioritized for re-presentation in review squares.

The fixed question format allows you to identify "that question in that square," enabling you to pinpoint and overcome your weak points.


[Step-by-Step Hints & Explanations]
Hints are revealed step-by-step if you don't understand. There are no penalties, so you can use them with confidence. Explanations are also displayed after correct/incorrect answers.


[Maintain Motivation with XP and Levels]
Earn XP by correctly answering commands. Correct answers without hints earn bonus XP.

As your level increases, stages are unlocked and characters change.


[Fully Offline Compatible]
All question data is included in the app. You can learn anytime, anywhere, even without an internet connection, on the train or at home.


[Original Pixel Art Design]
An original pixel art world reminiscent of retro 16-bit RPGs. As the difficulty level increases, the stage themes change from grassland to forest to cave to castle to demon lord's castle.

■ Contents
Includes a wide range of major commands, from Linux basics to the equivalent of LINUC/LPIC Levels 1-3.

It's like a game, but the content is serious.
