Minishell: A Bash Shell Implementation

Overview

The Minishell project is a simplified implementation of a UNIX shell written in C. It replicates basic shell behavior such as executing commands, handling redirections, and managing processes. The project helps understand how shells work under the hood, including parsing, process management, and file descriptors. 🐚⚙️🖥️

Features

• Command execution with execve.

• Built-in commands:

  • echo (with -n option)
  • cd (with relative/absolute paths and ~)
  • pwd
  • export
  • unset
  • env
  • exit

• Pipes (|) for inter-process communication.

• Input/output redirections (<, >, >>, <<).

• Environment variable expansion ($VAR).

• Signal handling (Ctrl-C, Ctrl-\, Ctrl-D) similar to bash.

• Robust error handling and exit codes matching bash behavior.
