As we all know, file copying on Linux has long relied on the classic cp command, which remains reliable but offers little feedback and limited control over long or complex operations.
To address this, a promising new Rust-based command-line tool called cpx emerge, designed as an alternative rather than a replacement, that approaches the same task with a focus on performance, visibility, and configurability.
It targets scenarios where large directory trees, interrupted transfers, or the need for detailed progress reporting make standard tools less convenient to use. The project is currently Linux-only and leverages modern kernel features to improve copy throughput and reliability.
I’ve had cp aliased to rsync with my flags for years. It seems like a lot of newcomers try to “fix” stuff before they really understand what’s available. Or they just like to play around with different programming languages. Which is fine, but usually it’s not really interesting to me.
you seem to have added a condescending comment before you understood the goals. 2-5x speedup over rsync (their benchmarks, but still) seems significant on its own, and an interface that doesn’t require aliasing to be useful is also nice
Nope, thanks for projecting though. I just didn’t mention the multi-threaded because, again, it doesn’t speed up anything. Transfer speed has always been the bottleneck, unless you’re talking about heavy data-center type use. Like I said, if it’s interesting to you, go for it. I don’t see a need to reinvent the wheel on core utilities.
wym doesn’t speed anything up? they have a very thorough page of benchmarks
