I like to know meaning of groups in Linux
After 1 year & few months of being Linuxer on Fedora, I feel myself ready now to go more deep in Linux. A step in this road, is the knowledge of meaning of groups already existing on Linux Fedora. I mean the following:
Go to system setting, under administration select "Users & Groups". In "Group" tab, there are many groups ... I need to know what each of them mean? & what the result of adding user to each of them or removing it from any of them?
Is there a document or link explain them?
