# minigrep This is a very useful program that lets you search for lines that contain a specific string within a file. # Example usage I do not know how to compile to an executable right now, so that's an issue. Search for lines containing "frog": ``` cargo run -- frog poem.txt # Outputs "How public, like a frog" ``` Search for lines containing "you know": ``` cargo run -- "you know" poem.txt # Outputs "They'd banish us, you know." ``` Search for lines containing "to", but case insensitive: ``` IGNORE_CASE=1 cargo run -- "to" poem.txt # Outputs Are you nobody, too? How dreary to be somebody! To tell your name the livelong day To an admiring bog! ```
