Struct std::process::Command

Builder for creating a process.

Example

use std::process::{Stdio, Command};
use std::string::trim;
use std::fs::Path;

let command = Command::new(Path::new("/usr/bin/uname"))
    .stdout(Stdio::Piped)
    .args(&["-s"]);

let output = command.spawn()
    .unwrap()
    .wait_with_output()
    .unwrap();
defer output.free();

// Prints "Running on Linux"
println!("Running on {}", output.stdout[..].trim());
