Today we'll be expanding on the subject of groups (user groups) in Linux. The aim is to provide you with better intuition on how they work, and how we can use them in particular situations. We'll also briefly discuss the relationship between groups and file permissions and how we might limit their privileges. In addition we'll be covering some of the technicalities, such as creating new groups and adding users to them. But, we'll mainly focus on improving our understanding of groups in general.
