Command Line Rust

This repo is to deepen my understanding of how to program in Rust from the book Command Line Rust; which challenges you to implement common bash commands. https://www.amazon.com/Command-Line-Rust-Project-Based-Primer-Writing/dp/1098109430

Notes / Things I Learned

• bash command, echo $? will print the result of the last program run in bash
• using {:#?} in a println! will pretty print output
• match can take a guard, after the pattern match, ie:

    Ok(n) if n > 0 => Ok(n),
    _ => Err(From::from(val)),
}
