Struct Cmd 

pub struct Cmd { /* private fields */ }

命令结构体，用于构建和执行系统命令

use e_utils::{shell_open, Cmd};
fn test_cmd() {
  let output = Cmd::new("echo Hello from cmd").output().unwrap();
  assert_eq!(output.stdout, "Hello from cmd");
  assert!(Cmd::new("echo Hello from cmd")
    .output()
    .is_err());
}
fn test_shell_open_windows() {
  assert!(shell_open("C:\\").is_ok());
}
fn main() {
  test_cmd();
  test_shell_open_windows();
}
