This Rust project aims to create command-line utilities that mimic some basic functionalities of popular Unix utilities. The purpose of this project is to provide a hands-on experience in learning Rust by building simple yet useful tools. Rewriting existing tools in Rust can be an excellent way to grasp the language's syntax, data structures, and standard library.

The project will consist of the following utilities:

• echo: Repeats input
• cat: Concatenates files
• ls: Lists directories
• find: Locates files or directories
• grep: Matches text in files

Apart from the standard Rust libraries, no additional crates or dependencies are required for these utilities.
