Execute system commands in Rust using std::process::Command to spawn processes and capture their output.

Use std::process::Command to spawn external processes, configure arguments, and capture output.

use std::process::Command;

fn main() {
    let output = Command::new("ls")
        .arg("-l")
        .output()
        .expect("Failed to execute command");

    println!("stdout: {}", String::from_utf8_lossy(&output.stdout));
}
