在java中执行sudo 命令

 *    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：

package cn.bywin.cbvsp.common.utils;

import cn.bywin.cbvsp.DAL.BO.po.MyUserInfo;
import com.jcraft.jsch.*;

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

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 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 graphicsCardNames = shell.getStandardOutput();
        graphicsCardNames.forEach(System.out::println);
    }
