关于android 调用外部命令的问题（Runtime.getRuntime().exec参数）

android 调用外部命令的问题（Runtime.getRuntime().exec参数）
调用ls还有cat命名是没问题的，但是有些命令用不了，例如ll，打印显示环境有问题，不知道怎么解？

代码：
private String ssss() {
String TAG2 = "CMD";
try {

    String  cmd="ls";
    Process process =Runtime.getRuntime().exec(cmd);
    InputStream in1 = process.getInputStream();
    BufferedReader reader1 = new BufferedReader(new InputStreamReader(in1));
    String line1;
    Log.i(TAG2, "返回结果" + reader1.readLine());
    while ((line1 = reader1.readLine()) != null) {

        Log.i(TAG2, "返回结果=" + line1);
    }
    in1.close();
} catch (IOException ex) {
    ex.printStackTrace();
    //  result2 = "N/A";
}
return null;

}

String cmd="ls"打印结果：

android 里面没有ll这个命令，用ls -l

和权限有关系吧就像windows 需要管理员权限一样

我装了一个ethtool工具（装在/system/bin下） $ethtool eth0 可以查看以太网信息

写了个apk，调用这个命令，然后返回打印信息

用2不同的Cubieboard开发板一个能用一个不能用，，，但是直接在板子上adb shell（执行ethtool eth0）是可以用的

下面是打印信息：
