psh - Python Shell (POSIX Compliant Implementation)

For this project, I developed a POSIX-compliant shell capable of interpreting and executing shell commands. The shell supports both external programs and built-in commands such as cd, pwd, echo, and more. Throughout this project, I gained expertise in shell command parsing, Read-Eval-Print Loop (REPL) design, and the implementation of built-in commands.

Key Features:

• Command Parsing: Handles various shell commands and arguments.
• REPL Implementation: Continuously reads and executes user inputs.
• Built-in Commands: Includes cd, pwd, echo, and type.

Usage:

Run the psh script to start the shell. Use commands like echo, pwd, cd, and type.

Future Enhancements:

• Command History: Navigate through previously entered commands.
• Advanced Parsing: Support for piping and redirection.
• Custom Prompt: Customizable shell prompt.
• Configuration File: User-specific settings and startup commands.
