Overview
A POSIX-compliant UNIX command shell built in C featuring REPL execution, command parsing, process management, and built-in commands.
A lightweight, POSIX-compliant UNIX shell implemented in C from first principles. Built to master low-level process management, command string tokenization, and system execution. Features built-in utility commands (cd, pwd, echo, type, exit), file redirection, and binary lookup across the system PATH environment variable.
Key Features & Technical Architecture
