In linux, some ordinary users are temporarily allowed to execute certain commands as other users (including root), which is realized by sudo

Sudo's rules on which users to manage are stored in the / etc/sudoers file, or in the / etc/sudoers.d/ directory, you can generate the files yourself, but you need to change the permissions of the files to 440.

When editing a file, using the visudo command will automatically edit the / etc/sudoers file. Add the-f parameter to write the file in the / etc/sudoers.d directory, and have the function of syntax checking. The default is to use vi to write the file. In order to easily manage the color, you need to add it to the / etc/profiles file.

Export EDITOR=vim and make it effective.

Visudo-c: automatically checks the format of these files
