grrs - A Rust CLI Search Tool

This is a learning project based on the Command Line Applications in Rust tutorial. The project implements a simple grep-like command-line tool that searches for a pattern in a file.

Project Overview

grrs (pronounced "grass") is a simple CLI tool that:

• Takes a pattern and a file path as command-line arguments
• Searches for the pattern in the specified file
• Prints each line that contains the pattern

This project demonstrates:

• Command-line argument parsing with clap
• File I/O operations in Rust
• Error handling with the Result type
• Structuring a Rust CLI application
