minus-square30p87@feddit.delinkfedilinkarrow-up10·1 year agoNo, 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-square30p87@feddit.delinkfedilinkarrow-up6·1 year agoI did too. Multiple times in fact, I had to look at the other Rust code!
minus-squarepranaless@beehaw.orglinkfedilinkarrow-up1·1 year agoYes 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.

Isn’t echo a shell builtin?
