minigrep

A simple implementation of the grep command-line tool, written in Rust.

Usage

minigrep <query> <file_path>

• <query>: The string to search for.
• <file_path>: The path to the file to search in.

Examples

Basic Search

To search for the word "nobody" in a file named poem.txt:

$ cat poem.txt
I'm nobody! Who are you?
Are you nobody, too?
Then there's a pair of us - don't tell!
They'd banish us, you know.

How dreary to be somebody!
How public, like a frog
To tell your name the livelong day
To an admiring bog!

$ minigrep nobody poem.txt
Found I'm nobody! Who are you?
Found Are you nobody, too?

Case-Insensitive Search

To perform a case-insensitive search, set the CASE_MODE environment variable to insensitive.

$ export CASE_MODE=insensitive
$ minigrep rUsT poem.txt
