UVash Final Release

Final Release of UVash

This release marks the completion of the core architecture for the custom Unix shell, demonstrating low-level system programming and POSIX standard compliance.

Key Features Implemented

• Command Execution: Robust handling of external binaries via execvp() with dynamic path resolution.
• Concurrent Processing (&): Parallel execution of multiple commands with strict parent-child synchronization using fork() and waitpid().
• I/O Redirection (>): Output routing to custom files utilizing file descriptor manipulation and dup2().
• Built-in Commands: Native implementation of cd for directory traversal and exit for safe process termination.
• Memory Safety: Optimized pointer arithmetic for zero-copy string parsing and strict memory deallocation to prevent leaks.
