Looking for a small boring rust project to help my learning.

I am new to Rust, but I already see why people like it so much. I have done some very small personal projects, but now I want to do something more community oriented.

Is there a small non web project that anyone could use a hand with? Re-writing a simple Linux tool. Updating an existing project. Boring and tedious is fine, as I want to get in the habit of doing daily Rust work.

My background is in Java server side with some UI work.
