**LinuxMenu** is a lightweight, terminal-based system administration utility engineered in pure ANSI C for Linux and Unix-like environments. Designed for developers, sysadmins, and power users, it provides an intuitive, menu-driven interface for accessing essential system tools, configuration utilities, and diagnostic commands without memorizing complex syntax. The application features a hierarchical text-based UI with ANSI color-coded rendering, organizing over 100+ tools into logical categories: System Monitoring, Network Diagnostics, File Management, Process Control, Security, and Package Management. Built with a static `ToolEntry` struct array and stack allocation, LinuxMenu ensures zero external dependencies, deterministic performance, and minimal memory footprint (~40 KB binary). Key capabilities include dynamic command execution via `system()` or `execvp()` with user confirmation, real-time system telemetry display (CPU, memory, disk usage), and keyword search for rapid tool discovery. Its modular architecture separates UI rendering, command dispatch, and platform-specific logic, enabling straightforward extension. Strict input validation, buffer-safe string handling, and portable compilation flags ensure robustness across diverse distributions. Ideal for rapid troubleshooting, educational exploration, or workflow acceleration, LinuxMenu transforms scattered CLI knowledge into a unified, keyboard-driven reference. With MIT licensing and transparent source code, the project invites customization for personalized toolsets or integration into larger automation pipelines—empowering users with reliable, offline-capable system management while exemplifying disciplined native C programming. 🔧🐧💻
