Basic Shell

A simplified shell that offers a foundational command-line experience.

Key Functionalities

• User-Friendly Prompt: Displays a clear prompt and patiently awaits user input.
• One-Line Commands: Accepts straightforward commands, each ending with a newline. No semicolons, pipes, redirections, or other intricate features are necessary.
• Single-Line Execution: Processes commands exclusively within a single line, without passing arguments to programs.
• Error Handling: Gracefully manages scenarios where executables are not found, printing informative error messages and returning the prompt.
• End-of-File Mastery: Seamlessly handles "End of file" conditions (Ctrl+D).

Current Limitations

• PATH Independence: Operates without reliance on the PATH environment variable.
• No Built-Ins: Does not implement built-in commands.
• Special Character Avoidance: Refrains from handling special characters such as ", ', `, , *, &, and #.
• Cursor Stationarity: Maintains a steady cursor position.
• Argument-Free Operation: Executes commands without the complexity of arguments.

Usage

To use the Basic Shell, simply type in a command and press Enter. The command line will always end with a newline. For example, to run the ls command, you would type the following:

The Basic Shell will then display a list of files in the current directory.

To exit the Basic Shell, press Ctrl+D.
