The sudoers file can provide detailed control over user privileges but, with very little effort, you can still get a lot of benefit from sudo. In this post, we’re going to look at some simple ways to get a lot of value out of the sudo command.
Trick #1: Nearly effortless sudo usage
The default file on most Linux distributions makes it very simple to give select users the ability to run commands as root. In fact, you don’t even have to edit the /etc/sudoers file in any way to get started. Instead, you just add the users to the sudo or admin group on the system and you’re done.
Adding users to the sudo or admin group in the /etc/group file gives them permission to run commands using sudo.
