A custom Unix shell implementation with basic functionality inspired by bash
Minishell is a Unix shell implementation that recreates essential functionalities of a command-line interpreter. This project focuses on parsing command syntax, implementing built-in commands, managing processes, and handling signals. It's developed as part of the 42 school curriculum to deepen understanding of process creation and control.
