⣿ ZOTHOS × 1NC0GN30 // SOVEREIGN LINUX DOJO v3.4
Master Linux from Kernel to Production in 30 Digestible Days.
Built for rapid student comprehension and muscle memory. Every day is broken into three bite-sized sessions—🍳 Breakfast (Core Syntax), 🥪 Lunch (Operational Flags), and 🍽️ Dinner (Hardening & Pipelines)—available in both the native C TUI (./control-panel) and this interactive Web Mission Terminal .
$ git clone https://github.com/1nc0gn30/30-days-of-Linux-Fundamentals.git && cd 30-days-of-Linux-Fundamentals && ./control-panel Copy TUI
Progress-aware resume syncs automatically as you complete drills.

🍳 Breakfast (Morning Syntax) : Build foundational muscle memory on 6–10 core commands with instant hints.🥪 Lunch (Midday Workflows) : Combine flags, pipes, and process/disk/network diagnostics.🍽️ Dinner (Evening Hardening) : Apply security permissions, firewall rules, systemd units, and shell automation.📖 Built-In Visual Study Guides : Every session opens with a 60-Second Mental Model diagram and cheat-sheet table. HANDS-ON VISUAL MENTAL MODELS
Interactive Linux Architecture Labs Stop memorizing numbers blindly—interact with Linux permissions, the filesystem hierarchy, and stream pipelines right here.
VISUAL LAB 01 · PERMISSIONS
Interactive chmod Octal & Bitwise Matrix 755 Script 644 Config 600 SSH Key 750 Team
Toggle Read (4), Write (2), and Execute (1) bits to see how octal numbers map to ls -l permission strings.
Octal Mode 755
Symbolic Mode -rwxr-xr-x
Terminal Command chmod 755 deploy.sh && ls -l deploy.sh
Standard mode for executable scripts and public directories: Owner has full control (7), Group and Others can read and execute (5).
VISUAL LAB 02 · FILESYSTEM HIERARCHY (FHS)
Interactive Linux Root (/) Directory Explorer Click any directory in the Linux Filesystem Hierarchy Standard to inspect what lives there and which commands query it.
/etc /var /proc /bin /home /dev /tmp /usr
/etc — Host-Specific System Configuration Days 01, 11, 12, 15, 21
Contains static plain-text configuration files for the operating system and installed daemons. Zero binaries live here—only declarative configuration.
VISUAL LAB 03 · UNIX PHILOSOPHY & STREAMS
Interactive Linux Pipe (|) & Log Triage Simulator Stage 1: cat Stage 2: | grep Stage 3: | awk Stage 4: | sort | uniq -c
Click each stage to watch how raw security logs flow through stdout (FD 1) into stdin (FD 0) of the next tool to isolate an attacker IP.
