The Simple C Shell is a command-line shell program developed in C to explore the essential workings of shell environments. It supports several built-in commands, including $cd for changing directories, $help for displaying command information, $exit to terminate the session, and $history to review previously executed commands in the current session. Additionally, this shell allows for executing external commands available within the system's PATH, such as $ls, $pwd, and $echo.
This project is based on Stephen Brennan's lsh and serves as an educational tool to demonstrate the primary loop in a shell program, which involves reading, parsing, and executing commands. The shell emphasizes fundamental shell operations and provides insights into how command-line interfaces function at a basic level.
