*    1. 修改/etc/sudoers文件，在其中添加一行：
     *          username  ALL=(ALL) NOPASSWD:ALL
     *       其中，"username"是需要运行这个程序的用户名。

/bin/bash -c echo password |sudo -S command

Shell（JSCH）工具类：

执行代码：

public static void main(String[] args) {
            Shell shell = new Shell("192.168.161.152","root","linbinbhs7");
            shell.execute("/bin/bash -c echo linbinbhs7 |sudo -S ls");
            ArrayList<String> graphicsCardNames = shell.getStandardOutput();
            graphicsCardNames.forEach(e->{
                System.out.println(e);
            });
        }

**删除指定时间的文件**

public class TestShell {
        public static void main(String[] args) {
            Shell shell = new Shell("192.168.96.136","developer","de183!!!");
            shell.execute("/bin/bash -c echo de183!!! |sudo -S find /home/developer/temp -type f -mmin +1 -exec rm -rfv {} \\; > /home/developer/temp/nohup.out;");
            ArrayList<String> graphicsCardNames = shell.getStandardOutput();
            graphicsCardNames.forEach(System.out::println);
        }
    }
