Rust Coreutils 0.1 Released with Big Performance Gains – Matches or Exceeds GNU

With Ubuntu 25.10 planning to ship the Rust-based Coreutils "uutils" by default, it's a big year ahead for this alternative to GNU Coreutils. In furthering along the project's goals, today marks the Rust Coreutils v0.1 release.

Succeeding the Rust Coreutils 0.0.30 release from two months ago is now Rust Coreutils 0.1. The version bump to the v0.1 milestone comes with this version delivering "major performance gains" as well as SELinux support and improved GNU Coreutils compatibility.

On the performance front, commands like wc, ls, cat, tail, seq and other Coreutils are now matching or exceeding the performance delivered by GNU Coreutils. This makes Rust Coreutils all the more compelling in that beyond being written in Rust for memory safety is also able to begin outperforming the C-based GNU Coreutils.

Rust Coreutils 0.1 adds SELinux integration for cp, mkdir, ls, install, and other common commands.

Rust Coreutils 0.1 is passing 522 tests from the GNU Test Suite, up from 507 with the prior version.
