echo Hello World!

• pranaless@beehaw.org ⁨1⁩ ⁨year⁩ ago

  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!

      Isn’t echo a shell builtin?

      source

      • pranaless@beehaw.org ⁨1⁩ ⁨year⁩ 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.
