An article details a personal experiment where standard Linux coreutils were replaced with versions written in Rust. The author reports that these alternatives performed surprisingly faster. The piece was published on February 20, 2026.
The article, titled "I replaced my standard Linux coreutils with Rust versions and it’s surprisingly faster," explores the potential benefits of using Rust implementations for essential Linux command-line tools. Coreutils, which include fundamental utilities like ls, cp, and mv, are typically written in C for most Linux distributions.
In the experiment, the author substituted these standard tools with Rust-based equivalents, such as those from projects like uutils or similar Rust rewrites. The results indicated improved speed, challenging the notion that core commands might not be keeping pace with modern hardware demands, as hinted in the description: "What if your core commands aren’t keeping up?"
This hands-on test highlights ongoing efforts in the open-source community to reimplement Unix tools in safer, potentially more efficient languages like Rust. While the article focuses on performance gains, it does not specify exact benchmarks or hardware used, emphasizing the subjective surprise at the speedup.
Published on February 20, 2026, the piece encourages readers interested in system optimization to consider such alternatives for their setups.
