What is grep?

Classic command line tool grep (globally search a regular expression and print).

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.

Usage

cargo run 'search_string' 'path/filename.txt'

Default behavior is case-sensitive search, provide 'CASE_INSENSITIVE' environment variable with any value for case-insensitive searches.

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

Test

cargo test
