minus-square pranaless ( @pranaless@beehaw.org ) linkfedilink31•1 year agouse std::process::Command; fn main() { Command::new("sh") .arg("-c") .arg("echo Hello World!") .spawn() .unwrap(); } Like this?
minus-square 30p87 ( @30p87@feddit.de ) linkfedilink10•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-square 30p87 ( @30p87@feddit.de ) linkfedilink6•1 year agoI did too. Multiple times in fact, I had to look at the other Rust code!
minus-square TadoTheRustacean ( @TadoTheRustacean@programming.dev ) OPlinkfedilink2•1 year agoIsn’t echo a shell builtin?
minus-square pranaless ( @pranaless@beehaw.org ) linkfedilink1•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.
