Systemctl Command Learning Simulator

📘 Overview

The Systemctl Command Learning Simulator is a web-based educational tool designed to help users safely learn and practice Linux systemctl commands.
It mimics the real command-line environment, letting learners execute simulated systemctl commands (like start, stop, enable, status) without touching an actual Linux system.

This project is especially useful for beginners and cyber security trainees who want to master Linux service management safely.

---

🧩 Problem Statement

Practicing systemctl commands on live Linux systems can be risky for new learners.
Mistakes might lead to service disruption or system instability, and setting up safe virtual machines is time-consuming.

The simulator provides a controlled, browser-based environment that allows users to safely experiment with systemctl commands — complete with realistic feedback and tutorials.

🎯 Project Objectives

• ✅ Provide a safe, web-based environment for systemctl command practice
• ✅ Simulate realistic systemd service responses
• ✅ Offer guided tutorials and instant feedback
• ✅ Enable learning without requiring a Linux installation
• ✅ Help users build confidence in Linux service management

---

🚀 Features

• 🖥️ Interactive terminal interface for entering real systemctl commands
• ⚙️ Simulation of services like nginx, sshd, and docker
• 📘 Step-by-step tutorials and command examples
• 🧭 Feedback and hints for incorrect commands
• 🧑‍💻 Browser-based, no installation or Linux setup required
• 🌐 Responsive design for all devices
