Systems Programming: Building a Unix-like Shell in Rust

Edit page

Objective

This guide walks you through creating Mini-Shell, a Unix-like shell in Rust, covering command execution, piping, I/O redirection, built-in commands, background processes, and signal handling.

Step 1: Environment Setup

Suggested File Structure

mini-shell/
├── src/
│   ├── main.rs
│   ├── parser.rs
│   ├── executor.rs
│   └── utils.rs
├── tests/
├── Cargo.toml
└── README.md

Step 2: Implementing the Shell Loop

Step 3: Executing External Commands

Step 4: Built-in Commands (cd, exit)

Step 5: I/O Redirection (<, >)

Step 6: Command Piping (|)

Step 7: Background Execution (&)

Step 8: Signal Handling

Step 9: Testing and Automation
