File System Explorer

A lightweight C-based file system exploration tool that demonstrates low-level system programming through direct system calls and POSIX APIs. Built to understand the fundamentals of file I/O, directory traversal, and process management in Linux.

Features

• Dual File Access - Compare standard library functions vs. raw system calls
• Directory Navigation - Browse and explore filesystem with detailed metadata
• Process Management - View process information and execute shell commands
• Interactive CLI - Clean menu-driven interface for exploration
• Signal Handling - Graceful shutdown with SIGINT handling

🚀 Quick Start

# Build
make

# Run
./fsexplorer

# Clean
make clean

Tech Stack

• Language: C (C99)
• Build System: Make
• System APIs: POSIX system calls, Linux file APIs
• Features: Signal handling, process management, file I/O

What I Learned

• Direct vs. buffered I/O operations
• File descriptor management and system call efficiency
• POSIX directory APIs and metadata extraction
• Process spawning and signal handling in C
