linux用java创建进程

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class ProcessExample {
    public static void main(String[] args) {
        ProcessBuilder processBuilder = new ProcessBuilder("ls", "-l");
        processBuilder.redirectErrorStream(true); // 将错误流合并到标准输出流

        try {
            Process process = processBuilder.start();

            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }

            int exitCode = process.waitFor();
            System.out.println("Process exited with code " + exitCode);
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}
