Creating a command line shell is a fundamental exercise for understanding operating systems and system programming. I embarked on this project to develop a Unix-like command line shell in C, aiming to implement core features such as boolean operations, pipes, and file redirection.
Development and Features
The shell I developed supports complex command structures through efficient CLI tokenization. By constructing a tree data structure, the shell can parse and execute commands effectively. This structure allows for advanced functionalities such as boolean operations and piping, essential for robust command line interfaces.
Optimization with Makefile
To ensure the build process is optimized, I created a comprehensive Makefile. This file includes clear dependency rules that expedite compilation, making the development process smoother and more efficient.
Conclusion
Developing a Unix-like command line shell in C was an enlightening experience that deepened my understanding of system-level programming. This project highlights the importance of efficient parsing and execution mechanisms, providing a solid foundation for further exploration in operating systems and system software.
