Crate simple_grep

SimpleGrep 🕵️‍♂️📄

simple_grep is a simple command-line tool written in Rust to search for lines that contain a specific query string in a given text file, similar to Unix grep.

It supports both case-sensitive and case-insensitive search based on the IGNORE_CASE environment variable.

Example

cargo run -- <query> <file_path>

Case-insensitive search:

IGNORE_CASE=1 cargo run -- <query> <file_path>
