本文介绍用Rust重新实现GNU coreutils的开源项目Rust coreutils，该项目已成为兼容多数Linux发行版的直接替代品，为关键软件的替代开发提供了见解，也凸显现代编程特性对遗留软件包开发的吸引力。
AI 中文摘要
GNU核心工具集（coreutils）是现代UNIX系统中的关键软件包，包含约100个基础命令，如ls、cp和cat，每天在数百万台计算机上运行。不过，GNU coreutils是遗留软件，其C代码库可追溯至20世纪90年代初，且功能已基本完善。若要重新实现这一重要软件包，该如何高效完成，原因何在？本文介绍Rust coreutils的开发过程，它是用Rust编程语言对GNU coreutils进行的当代开源重新实现，目前已成为GNU coreutils的直接替代品，兼容大多数Linux发行版。通过将Rust coreutils与其前身对比，本文为创建关键软件的可靠替代品提供了见解，并强调现代编程特性如何吸引对遗留软件包的开发兴趣。
英文摘要
GNU core utilities (coreutils) is a crucial package in modern UNIX systems. It comprises around 100 fundamental commands---like ls, cp, and cat---which run every day on millions of computers. However, GNU coreutils is also legacy software, with its C codebase dating back to the early 1990s and arguably feature-complete. If one were to consider reimplementing this essential package, how would they do so effectively, and why? This paper recounts the development of Rust coreutils, a contemporary open source reimplementation of GNU coreutils in the Rust programming language, which has reached the status of a drop-in replacement for GNU coreutils, compatible with most Linux distributions. By comparing Rust coreutils with its ancestor, we offer insights into creating a reliable substitute for critical software and highlight how modern programming features can attract development interest in legacy packages.
