rls

A Rust implementation of the classic Unix ls command.

Project Overview

rls aims to recreate the functionality of the ls command using Rust. This project serves as a learning exercise.

Note: This is a project for personal studies on how the file system API in rust functions.

Features

The goal is to implement the following ls options:

• rls: List all non-hidden files and directories in the current directory
• rls -a: List all files and directories, including hidden ones
• rls -A: List all files and directories except . and ..
• rls -l: Use long listing format
• rls -h: Print sizes in human-readable format (e.g., 1K, 234M, 2G)
• rls -R: List subdirectories recursively
• rls -d: List directories themselves, not their contents
• rls -r: Reverse order while sorting
• rls -S: Sort by file size, largest first
• rls -t: Sort by modification time, newest first
• rls -X: Sort alphabetically by entry extension

The implementation supports argument chaining. So you can use the command

rls -a -h -X

to list all files and directories sorted alphabetically and in a human readible format.
