Shell (CLI) - Implementation from Scratch

I developed a custom shell implementation using Java, which simulates the basic functionality of a command-line interface. The project includes core features like handling user commands, executing processes, managing built-in commands (like cd, exit, and pwd), and managing user input/output. Additionally, I implemented features for handling pipes, redirection, and background processes.

Command Execution: Supports the execution of system commands with arguments.

Built-in Commands: Implemented essential shell commands such as cd, pwd, and exit.

Pipes and Redirection: Enabled piping between commands and output redirection to files.

Background Processes: Allows for executing commands in the background using &.

Error Handling: Includes error handling for invalid commands and improper syntax.

Java-based: The shell is built using Java, demonstrating a strong understanding of the language and system-level programming concepts.
