    use std::process::Command;

fn main() {
    Command::new("sh")
        .arg("-c")
        .arg("echo Hello World!")
        .spawn()
        .unwrap();
}

    Like this?

      No, more like

      use std::process::Command; fn main() { Command::new("sh").arg("-c").arg("echo Hello World!").spawn().unwrap(); }

      .
      Just a little bit shorter, as it seems /s

          I did too. Multiple times in fact, I had to look at the other Rust code!

          Yes and no. While coreutils does provide an echo binary, shells also have a built-in for optimisation purposes.

          At first I had the code calling the binary directly, but then changed it to spawning a shell (and so using the builtin). It’s very cursed either way.
