minigrepf

minigrepf is a tiny command line tool built as an exercise from the book "The Rust Programming Language," chapter 12.

Usage

$ ls
poem.txt minigrepf

$ 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!

$ ./minigrepf to poem.txt
Are you nobody, too?
How dreary to be somebody!

$ IGNORE_CASE=1 ./minigrepf to poem.txt
Are you nobody, too?
How dreary to be somebody!
To tell your name the livelong day
To an admiring bog!
