Build Your Own Shell (Rust)

This is my implementation of the "Build Your Own Shell" Challenge provided by CodeCrafters, written in Rust.

It is a POSIX-compliant shell capable of interpreting shell commands, running built-in commands, and executing external programs.

Features

• Interactive REPL: Built with rustyline to support command history and auto-completion.
• Built-in Commands: Supports standard built-ins including cd, pwd, echo, exit, type, and history.
• Program Execution: Resolves and executes external programs found in the system's $PATH.
• Output Redirection: Supports standard output and standard error redirection (e.g., >, >>, 1>, 2>).
• Pipelining: Can chain multiple commands together using pipes (|), allowing concurrent execution of external commands.
• Path Auto-completion: Tab-completion for file and directory arguments, supporting partial matches.

Usage

You can build and run the shell locally using the provided script:

# Clone the repository
git clone <your-repo-url>
cd codecrafters-shell-rust

# Run the shell
./your_program.sh

Alternatively, you can use Cargo directly:

cargo run --release
