The most widely spread Chinese Blog posts on the Internet about this operation are very evil. For example ......

In fact, the idea is the same, mainly to edit/etc/sudoers:

$ Sudo multiple do

Add a line in the table. If you want to enable a user sudo without entering a password, it will start with the user name. If you want a group to have this privilege, it will start with % group name. For example:

Gnuhpc all = nopasswd: All
Indicates that gnuhpc does not need to perform sudo operations under any command.

% SysAdmin all = nopasswd:/usr/bin/apt-Get,/usr/bin/Aptitude

This indicates that the SysAdmin group does not need to perform sudo operations for apt-Get and aptitude.

Modify this to change the sudo timeout time: Defaults env_reset, timestamp_timeout = x
