A curated list of command-line utilities written in Rust

Note: I have moved this list to a proper repository. I'll leave this gist up, but it won't be updated. To submit an idea, open a PR on the repo.

Note that I have not tried all of these personally, and cannot and do not vouch for all of the tools listed here. In most cases, the descriptions here are copied directly from their code repos. Some may have been abandoned. Investigate before installing/using.

The ones I use regularly include: bat, dust, fd, fend, hyperfine, miniserve, ripgrep, just, cargo-audit and cargo-wipe.

Win zip()

I don't often use zip(), but by coincidence this week I ran into it a few times, using both Python and JavaScript. In the former, it's a built-in, but in the latter it's typically provided by a library like D3. And it struck me as kind of a fun warm-up challenge. How would you write this function in modern JavaScript?

Well, let's see how D3 does it. Oh, it's a wrapper around transpose(), here we go...

import min from "./min.js";

function length(d) {
