# MilliGrep
`Custom simplified implementation of grep`
## What is `grep`?
Classic command line tool `grep` (**g**lobally search a **r**egular **e**xpression and **p**rint).
## What is `milligrep`?
In the simplest use case, `milligrep` searches a specified file for a specified string. To do so, `milligrep` takes as its arguments a filename and a string. Then it reads the file, finds lines in that file that contain the string argument, and prints those lines.
`This project is built with Rust and uses Cargo as it's package manager.`

```bash
CASE_INSENSITIVE=1 cargo run 'search_string' 'path/filename.txt'
```
