🌳 Building `ctree`: A Lightweight Unix `tree` Clone in C

When I started learning low-level programming, I wanted to build something practical — not just theory. So I decided to recreate a simplified version of the Unix tree command using C. This project, called ctree , helped me deeply understand filesystem traversal, recursion, and how real CLI tools work under the hood. 🔗 Source Code 👉 Check out the full project on GitHub: farhadrahimiklie / ctree 🚀 What is ctree ? ctree is a lightweight command-line tool that prints directory structures in a tree-like format — just like the Unix tree utility. But instead of using an existing tool, I built it from scratch using pure C and POSIX APIs. 🧠 What I Learned This project was more than just printing directories. It taught me: How to use opendir() and readdir() to read directories How to use stat() to detect files vs directories Recursive directory traversal Memory management with strdup() and free() Sorting using qsort() Building CLI tools with argument parsing Designing modular C projects (header
