## What it is
uutils coreutils is a cross-platform reimplementation of the GNU coreutils command-line utilities written in Rust, aiming to be a drop-in replacement with identical output and exit codes. It ships by default on Ubuntu 25.10+ and runs on Linux, macOS, BSD, Windows, WASI, and other platforms.

## Use cases
- replace GNU coreutils with a memory-safe Rust implementation
- run the same shell utilities on Windows, macOS, and Linux
- port shell scripts between operating systems without platform-specific tools
- get better error messages from standard command-line utilities
- use coreutils in WebAssembly or embedded environments
- improve performance of common command-line operations

## When to choose
- you want a memory-safe, modern replacement for GNU coreutils
- you need identical coreutils behavior across Linux, macOS, Windows, and BSD
- you are building cross-platform scripts that rely on GNU-compatible utilities
- you want faster performance and better error messages than GNU coreutils

## When to avoid
- you depend on exact GNU coreutils behavior for every option, since some options may be missing or differ
- you need a battle-tested, decades-proven toolchain for critical production systems
- your environment requires strict GNU licensing or packaging policies

## Facets
- artifact type: cli-tool
- maturity: active
- function: cli, developer-tools, file-system, internationalization
- domain: developer-tools, cross-platform, operating-systems
- platform: windows, bsd, rust, cli, cross-platform, wasm
- tags: coreutils, gnu-coreutils, busybox, drop-in-replacement, memory-safety, unix-utilities, command-line, linux, macos
