🌀 Flux — A Minimal Shell in C

Flux is a minimal, dependency-light shell written in C for Unix-like operating systems (Linux, BSD, and others).
It is designed to be small, educational, and portable.

---

✨ Features

• Flexible and customizable shell prompt (~/.flux.conf)
• You can navigate between directories using the built-in cd command
• Persistent command history (~/.flux_history)
• Lightweight — depends only on standard C and POSIX system calls
• Simple command execution via execvp
• Perfect for learning how shells work internally

---

🧩 Build & Run

git clone https://github.com/mateo-rfz/flux.git
cd flux/
make
./build/flux

Or compile manually:

cd flux/
gcc -o flux src/flux.c  src/parser.c  src/shell_prompt.c  src/string_utils.c  src/utilities.c

---

⚙️ Configuration

Flux reads your prompt style from:

~/.flux.conf

Example:

%U@%H:%P$ -> usernmae@hostname:/home/username$  

Command history is automatically saved to:

~/.flux_history

---

🧠 Why Flux?

Flux is intentionally minimal — not a full-featured shell,
but a tool to learn how shells work under the hood: command parsing, forking, exec calls, and I/O redirection.

---

🗺️ Roadmap / TODO

• Add command auto-completion
• Add colored prompt support
• Improve history navigation (arrow keys)
• Add basic I/O redirection
