Using Coreutils in Rust

Rust is a systems programming language that aims to provide memory safety, concurrency, and performance. It is an excellent choice for building command-line tools and utilities, making it a natural fit for implementing coreutils, the collection of basic file, shell, and text manipulation tools found on Unix-like systems.

In this article, we will explore how to create coreutils in Rust, focusing on a few examples to demonstrate the power and flexibility of the language.

Coreutils is a package that contains many essential Unix command-line utilities, such as ls, cat, rm, cp, and mv. These utilities are fundamental to working with Unix-like systems and help users perform simple tasks like listing directories, concatenating files, and deleting files.

In this article, we will implement three coreutils in Rust:

Let’s start by implementing the cat utility, which reads files and outputs their content to the console. We will use the std::fs::File and std::io::Read modules from the Rust standard library to read files.
