Personally,

echo Hello World!
[-] pranaless@beehaw.org 30 points 2 years ago 
use std::process::Command;

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

Like this?

[-] 30p87@feddit.de 10 points 2 years ago

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

Isn't echo a shell builtin?

[-] pranaless@beehaw.org 1 points 2 years ago

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.
