🥥 bukoshell

As beautiful as a coconut shell — and twice as hard to crack! (probably)

This project is a small Bash-like shell that can parse and execute user commands, handle built-in functions, manage environment variables, run external programs, and support pipes, redirections, and proper signal handling.

Features

• Command parsing with single/double quotes, $ variable expansion, and $? exit status
• Built-in functions: echo (-n), cd, pwd, export, unset, env, exit
• Environment variable management (from environ, dynamic updates)
• External program execution via PATH lookup and execve
• Pipes (|) with multi-stage chaining
• Redirections: <, >, >>, << (heredoc with delimiter expansion control)
• Signal handling: SIGINT (Ctrl+C), SIGQUIT (Ctrl+) — parent ignores, children behave like Bash
• Robust error handling and exit codes (126, 127, syntax errors)

Bonus Features (as per 42 subject)

These are optional and not required for the base project:

• Wildcard expansion — supports * (matches any sequence in filenames)
• Logical operators — && (and), || (or) with short-circuit evaluation
• Subshells — (cmd1 && cmd2) (Proper environment isolation WIP)
