The article details a personal project to build a toy shell from scratch in C, covering the REPL loop, basic command execution, and features like pipes and tab completion. It's a technical walkthrough aimed at understanding shell internals rather than introducing new technology. The project serves as an educational exploration of low-level systems programming concepts.
Background
Shells are command-line interpreters that provide a user interface to access operating system services, commonly used in Unix-like systems. Building one from scratch is a classic educational exercise in systems programming to understand process management, I/O, and parsing.
