This project was an awesome deep dive into the heart of how Unix shells work! I built a fully functional miniature shell in C, mimicking the core features you see in Bash. The challenge? Doing it all from scratch, without relying on high-level libraries. It was all about understanding the raw power of system calls and low-level programming.
- Command Parsing & Execution: Taking your typed commands and figuring out what to do with them. Think of it as the shell's brain deciphering your instructions.
- Pipes (|) and Redirection (>, <, >>): Making data flow! Connecting the output of one command to the input of another, and shuffling data to and from files.
- Signal Handling (Ctrl+C, Ctrl+\): Learning how to gracefully respond to interruptions like
SIGINTandSIGQUIT. No crashing allowed! - Environment Variable Management: Handling those
$PATHand$HOMEvariables that make your system work. - Process Management (fork(), execve()): The magic of creating new processes to run your commands and then executing them.
- No High-Level Libraries: This was the real challenge! Everything was built using fundamental C functions and system calls.

Clone the repository:
git clone https://github.com/AKL001/MiniShell.git cd minishell -
Compile the project: Just run
makein the project directory:make
-
Run the shell: Once compiled, execute the
minishellbinary:./minishell
-
Exit the shell: Simply type
exitand press Enter.
- C Compiler (gcc): You'll need a C compiler to build the project.
- Linux or macOS Environment: This project relies on specific system calls and signal handling mechanisms common in these environments.
This project was a fantastic journey into systems programming, and I'm excited to build upon this foundation! 🚀
