Features

• Modular Command Structure: Organized and maintainable code.
• Comprehensive Command Support: Includes core shell commands such as echo, pwd, ls, cd, mkdir, rmdir, rm, cp, mv, chmod, chown, find, grep, head, tail, wc, ps, and kill.
• Extensible Design: Easy to add new commands.
• Error Handling: Clear and consistent error messages.
• Help Command: Lists all available commands and their usage.
