minus-square30p87 ( 30p87@feddit.de ) linkfedilinkarrow-up10·3 年前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

minus-squareTadoTheRustacean ( TadoTheRustacean@programming.dev ) OPlinkfedilinkarrow-up2·3 年前Isn’t echo a shell builtin?
minus-squarefable (she/they) ( pranaless@beehaw.org ) linkfedilinkarrow-up1·3 年前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.
