About the project:

# 🕵️‍♂️ minigrep

**minigrep** is a simple command-line tool written in **Rust** that lets you search for substrings in a file — inspired by the classic `grep`.

## 📦 Features

- 🔍 Search for any substring in a file
- ⚡ Fast and lightweight (thanks to Rust!)
- 📁 Read from files passed via command line
- 🧵 Case-insensitive search (via env var)

Example:

cargo run -- body poem.txt > output.txt 

This will print all lines in poem.txt that contain the word "body".

---

Case-Insensitive Search

To enable case-insensitive search, set the environment variable:

IGNORE_CASE=1 cargo run -- BODY poem.txt > output.txt  

---

2. Clone the repo:
