    Correct me if I'm wrong, but isn't it around 800 lines [1]?

  • Ubuntu 25.10 Replaces GNU Coreutils with Rust Uutils
    2 projects | news.ycombinator.com | 24 Apr 2025
    If this rewrite is indicative of other rewrites, we'll see a license change from GPL [1] to MIT.

    "Differences with GNU are treated as bugs." - https://github.com/uutils/coreutils#goals

    Wouldn't it be annoying though, to have to keep things bug-for-bug compatible on a green-field project? That priority may be the first compromise, and divergence is inevitable.

    Thinking of what if coreutils were ported to C#; what would folks think then? If the reaction would be the same, different, or ambivalent.

  • Rewriting essential Linux packages in Rust

    I can't find an official list of supported targets, but

    https://github.com/coreutils/coreutils/blob/master/README-in...

    contains notes on compiling for IRIX, HPUX, AIX, and OSF/1. So no, I would bet that it very much does run anywhere Linux runs, and a lot of places it doesn't.

    Yeah, the thing is that `yes` isn't a stand alone project, it is usually part of a bigger project such as coreutils (https://github.com/coreutils/coreutils/).

    For the comparison to be valid you would have to split up coreutils into roughly 100 individual repositories and replace many of the implementations with ones that are trivial, buggy, and/or unmaintained that pose a supply chain attack risk because it gets hard to keep track of what's maintained, by whom and how. Coreutils is close to 100kLOC and its programs aren't packaged individually. It is far, far from the random mess that are microlibraries in NPM.

    less (17kLOC), awk (43kLOC) and grep (4kLOC) are separate projects, but some of those require a bit more insight than much application code these days, so it makes sense that they are individual projects.

    >There is no such thing as a small legacy codebase

    Very true. As a followup, I think it's worth pointing out that command line applications in particular can cram a lot of functionality into very few LOC.

    Last night, I read through the source code for `cat` (yes, that `cat`) and it was only about 800 lines of fairly breezy C: https://github.com/coreutils/coreutils/blob/master/src/cat.c

    And a tiny CLI tool I use every day, several times a day, for learning Finnish, is about 200 lines of Python: https://github.com/hiAndrewQuinn/finstem

    AFAIK, the remote applications simply do an isatty() check on the stdout and that's it; a proper terminal is then apparently expected to correctly skip and quietly ignore any OSC sequence it does not understand. See the source of ls [0], for example.
