rust command stdin

Comment

use std::io::{self, Write};
use std::process::{Command, Stdio};

fn main() -> io::Result<()> {
    let mut child = Command::new("cat")
        .stdin(Stdio::piped())
        .stdout(Stdio::piped())
        .spawn()?;

    let child_stdin = child.stdin.as_mut().unwrap();
    child_stdin.write_all(b"Hello, world!\n")?;
    // Close stdin to finish and avoid indefinite blocking
    drop(child_stdin);
    
    let output = child.wait_with_output()?;

    println!("output = {:?}", output);

    Ok(())
}
