Linux - Group Management (addgroup, delgroup, adduser, deluser)

Managing Groups in Linux is relatively simple. It’s important to realize Linux users, groups and permissions are much simpler than in Windows Server.

Group Configuration File

sudo vim /etc/group – opens Group configuration file in read only mode (:q to quit)
Add Group

sudo addgroup GROUPNAME – adds group
Delete Group

sudo delgroup GROUPNAME – deletes group
Add Users to Group

sudo adduser USERNAME GROUPNAME – adds user to group
Delete Users from Group

sudo deluser USERNAME GROUPNAME – deletes user from group

Lm tell you something. You are one of the most important people on the YouTube when it comes to IT.
What's also really important is that you actually know stuff and provide knowledge without any bullshit and give way more realistic views than anyone else. I have been watching your videos for a very long time and it does not matter how old they are, they still provide the best/easiest/appropriate knowledge even today. I am super glad you started this Linux tutorials.
I don't really have nothing to offer except good wine and vodka my family makes haha. If there is any way I can send them to you, I would be super glad.
I dont know if you see this but, thank you a lot, because soon I will get a job by these videos.

These Linux videos are great, thanks :-) Not sure about VIM though, I've gotten used to nano. Maybe I'll give VIM another go when I get some moments to spare. I do enjoy the command line/terminal, especially when I'm trying out an unfamiliar distro and can't find something in the GUI.

Nice videos as always. Is there a way to continue this series and make an equivalent of Windows AD, or go with the extra features Zentyal has but you install them one by one in your server?
Thank you.

Hi Eli, thanks for the video, I have question that, what if Group file does not exist, then how can we add sudo to groups?

[tejasgoyal]

Hello! Do we need to make the users account first before adding or adduser can automatically create an instance of the user? Thanks

You've been around a long time Eli. I'm suprised you didn't touch up on this yet.
