MyShell

Linux



C System Calls System Programming

MyShell is an educational Linux mini shell written in C.

The goal of this project is to learn Linux system calls, POSIX APIs, and C system programming by building a simple shell from scratch.

The shell currently supports several basic Unix commands implemented for learning purposes.

Whenever possible, this project uses low-level Linux system calls instead of higher-level library functions to better understand how Unix shells work internally.

This project is still under development, and more features will be added over time to make the shell closer to a real Unix shell.
