Those who do not understand Unix are condemned to reinvent it, poorly. -- Henry Spencer Yay! Non-portable Unix tools! Just what everyone wants.

What's not portable about it? Rust is reasonably portable, no? Also they are claiming to be generally (but not strictly) POSIX-compatible.

Except, UNIX wasn't the first OS with a shell. There was at least 10 years of shell history before UNIX came to be.

This isn't reinventing Unix, this is a (cut down part of) Unix. (Unix the family, not the original Bell Labs OS, of course). And "non-portable" because it's only portable to Unix? That's... Approximately everything. Linux family and Darwin naively, NT via WSL/cygwin/etc., BSDs obviously, Android sorta-natively or via Termux, Chrome OS via Termux, crouton, or crostani(sp?). What is Unix not portable to?

  It's probably the usual complaint of Rust not being able to run on an obscure 1965-era calculator.

    I can't run C on a 8-bit calculator either. At least not using GCC or Clang or any other mainstream compiler. Sure, I could use some toy compiler for that, but then 99% of the libraries I'd like to use won't work there anyways, due to a variety of issues.

      I was about to object, but actually it looks like you're right; tigcc appears to only target the TI-89 et al. which run on the 16-bit Motorola 68000 series. A quick search doesn't give me any C compiler for the TI-84 after all. Your actual point, of course, is valid regardless:) EDIT: Oops, actually https://en.wikipedia.org/wiki/Small_Device_C_Compiler https://en.wikipedia.org/wiki/Small_Device_C_Compiler ... but then you're right about getting pretty obscure.

> Those who do not understand Unix are condemned to reinvent it, poorly. -- Henry Spencer I absolutely abhor this quote, I think it's taken out of context. First of all, it denotes hubris, which I hate. Secondly, it's totally anti-scientific, it assumes that Unix is some paragon of OS design, the zenith of Computer Science. I like Unix as much as the next IT guy, but let's cut it out with the cliché quotes. There's plenty of things Unix doesn't do that well (everything is a file, until it isn't; filenames are basically binary blobs, etc.: https://dwheeler.com/essays/fixing-unix-linux-filenames.html https://dwheeler.com/essays/fixing-unix-linux-filenames.html). Plus your comment is just silly, whoever implemented this obviously knew about Unix shells... It takes knowledge of Unix shells to implement another Unix-y shell.
