minigrep

A simple command-line tool written in Rust for searching for a query string in a file. Inspired by the classic grep utility, minigrep is a lightweight alternative for basic search needs.

Features

• Search for a string in a text file
• Case-sensitive and case-insensitive search modes
• Simple and easy-to-understand codebase

Usage

cargo run -- <QUERY> <FILENAME>

• <QUERY>: The string to search for.
• <FILENAME>: The path to the file to search in.

Example:

cargo run -- to poem.txt

To run in case-insensitive mode, set the CASE_INSENSITIVE environment variable:

CASE_INSENSITIVE=1 cargo run -- to poem.txt

Building

To build the project, ensure you have Rust installed, then run:

cargo build
