Basic Grep CLI in Rust

This is a basic Grep CLI implementation in Rust. It matches the main Regex expressions. This is a small research project.

How to run

  1. Ensure you have cargo (1.76) installed locally
  2. In the terminal run echo "sentence" | ./your_grep.sh -E "regex" where regex is the pattern to match

Example

Run echo "grep 101" | ./your_grep.sh -E "(\w+ \d\d\d)". The exit code will be the result.

Here you can find the Regex cheatsheet.

How to test

Run cargo test to run the tests
