The /etc/sudoers file is the configuration files for sudo. These is the file where the users and groups with root priviledges are stored.
Do not edit the /etc/sudoers by hand, use sudo visudo instead. visudo opens the /etc/sudoers file in the default text editor and gives a warning if you type something wrong in the file:
>>> /etc/sudoers: syntax error near line 21 <<<
What now?
Options are:
(e)dit sudoers file again
e(x)it without saving changes to sudoers file
(Q)uit and save changes to sudoers file (DANGER!)
What now?
