cpx Introduced as a Faster, Modern Replacement for Linux cp (linuxiac.com)

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.

It's a damn pain to remember all the flags. How many flags can a program friggin have? I'm always afraid that some flag I enter will reverse the sync and delete everything in the source folder because the target is empty.

I use rsync only when all params have been reseasrched and tested. cpx presumably just requires cpx - r source target instead of 5 rsync flags.

The only one you need is -a. -avx if you want verbose and compression.

I just looked it up and - x means one filesystem. But does - v give you a progress bar or just a lost of stuff copied?

IIRC rsync also treats the trailing slash in a special manner that I always have to look up.

The trailing slash is just following cp's own special treatment


# before
dir/
    file1
target/
    orig.txt



# no trailing slash - copy *dir* to target
cp -r /path/to/some/dir /my/target

# after
target/
    orig.txt
    dir/            # dir copied to target
        file1



# with trailing slash - copy *contents* of dir to target
cp -r /path/to/some/dir/ /my/target

# after
target/
    orig.txt
    file1            # contents of dir

--progress=info2 could be a bit shorter imo

What 5 flags did rsync need? I always just do -av and go about my day. And the -v is kinda optional.

How do you get the progress bar?
