推荐答案

最好的方法是使用 sudo，但既然你不想要最好的解决方案，你可以使用script 代替:

The best way of doing this is with sudo, but since you don't want the best solution, you can you can use script instead:

{ sleep 3; echo "yourpassword"; } | script -q -c 'su -c whoami' /dev/null

这将打印 root，whoami 的输出.

This will print root, the output of whoami.

在尝试调整它以运行您自己的命令之前，请确保逐字尝试此命令(替换密码)，因为调整它很困难且容易出错.

Please make sure to try this command verbatim (with password replaced) before trying to adapt it to run your own commands, since adapting it is difficult and error prone.
