Simple Shell in Rust

This Rust application is a simple shell that accepts basic commands like cd, pwd, ls, and exit. It's designed to demonstrate how to interact with the system's environment, file system, and processes in Rust.

Features

• Change Directory (cd): Changes the current working directory of the shell.
• Print Working Directory (pwd): Prints the current working directory.
• List (ls): Lists the contents of the current directory.
• Exit (exit): Exits the shell.

How to Run

1. Ensure you have Rust installed on your system. If not, you can install it from the official website.
2. Clone this repository or copy the source code into a .rs file.
3. Navigate to the directory containing the source code in your terminal.
4. Compile the code with rustc <filename>.rs.
5. Run the compiled executable with ./<filename> on Unix/Linux/macOS or <filename>.exe on Windows.

Usage

After running the application, you will be presented with a prompt (>). You can type any of the supported commands (cd, pwd, ls, exit) followed by Enter.

Example:

pwd 
/Users/username/projects/rust-shell 

Limitations

• The ls command currently prints raw metadata about directory entries, which might be less readable compared to the standard ls command output.
• Error handling is minimal, primarily using unwrap() for simplicity, which may cause the program to panic on errors instead of handling them gracefully.
