Bash Terminal Gateway in Rust

main.rs

// Code written by Mr.Ender for educational purposes only, version 2

use std::{process::Command, io};

fn main() {
    let host_name = Command::new("sh")
        .arg("-c")
        .arg("hostname")
        .output()
        .expect("failed to get host name");
    
    let host_name_string = String::from_utf8(host_name.stdout).unwrap();
    let terminal_prompt = format!("{}@Ubuntu:~$ ", &host_name_string[0..host_name_string.len() - 1]);
    
    println!("{}", terminal_prompt);

    loop {
        let mut buffer = String::new();
        let _ = io::stdin().read_line(&mut buffer);
        
        let output = Command::new("sh")
            .arg("-c")
            .arg(buffer.clone())
            .output()
            .expect("failed to execute process");
        
        println!("{}{}", terminal_prompt, buffer);
        println!("{}", String::from_utf8(output.stdout).unwrap())
    }
}

I updated the code to fix the bash prompt thingy to show the commands you entered
