Personally,
echo Hello World!-
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 just fucking threw up

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

Isn't echo a shell builtin?
-
Yes and no. While coreutils does provide an
echobinary, 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.
