如何在 Java 中以 sudo 权限执行 bash 命令?

问题描述

我正在使用 ProcessBuilder 来执行 bash 命令:

I'm using ProcessBuilder to execute bash commands:

import java.io.IOException;

public class Main {
    public static void main(String[] args) {
        try {
            Process pb = new ProcessBuilder("gedit").start();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

但我想做这样的事情:

Process pb = new ProcessBuilder("sudo", "gedit").start();

如何将超级用户密码传递给 bash?

How to pass superuser password to bash?

("gksudo", "gedit") 不会成功，因为它从 Ubuntu 13.04 开始就被删除了，我需要使用默认可用的命令来做到这一点.

("gksudo", "gedit") will not do the trick, because it was deleted since Ubuntu 13.04 and I need to do this with available by default commands.

编辑

gksudo 在上次更新时回到了 Ubuntu 13.04.

gksudo came back to Ubuntu 13.04 with the last update.

推荐答案

我认为你可以使用这个，但我有点犹豫要不要发布它.所以我只想说:

I think you can use this, but I'm a bit hesitant to post it. So I'll just say:

使用它需要您自担风险，不推荐，不要起诉我等...

public static void main(String[] args) throws IOException {

    String[] cmd = {"/bin/bash","-c","echo password| sudo -S ls"};
    Process pb = Runtime.getRuntime().exec(cmd);

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