About the Video:
Learn how to create new users on Linux (and how to remove Linux users). This video gives you a quick rundown of basic Linux commands like useradd, userdel, and usermod.
As a bonus, you’ll learn what actually happens behind the scenes when a new user is created in Linux. We’ll look at /etc/passwd, /etc/shadow, /etc/group, and a bunch of other things you might have been too scared to look at until now.

April 30, 2020How do I reset my sudo password on Linux? I'm trying to teach myself Linux with your videos hoping to learn and land an IT or cybersecurity job.

April 30, 2020@5:10 …"Get rid of some of these users before you push it online… use containerization… million open doors for bad guys to walk through" Ugh. I guess opening ports on my server BEFORE I finished your tutorials was an especially bad idea. Whoops. Close the blast doors! Close the blast doors!
My already infected network, "open the blast doors! Open the blast doors!"

April 30, 2020Nice example – One thing I find confusing in the example: most users seem to have a group named exactly as the user itself. It can be confusing in my mind, if you really need an own group (as opposed to joining an existing group), I would create group <username>_groupX. If a user has a group with the same name, and nobody else joins that group, it's the perfect example of a totally useless group

April 30, 2020It's funny that /etc/passwd ( the password file ) stores …. well, no passwords. I guess that on a sunny afternoon in 1973, it did store passwords literally in there

Mr. Suhaib

April 30, 2020im missing the need for all this.
Sure we know how to check if a user has a password, and if he doesn't then he cant login…but whats Shadow?whats the difference between that and the passwd folder?
whats the etc folder? why would we want to use the shell to add a user? isn't there an easier way? (or that question implies I should stick to Windows? :P)

Brooks Burris
April 30, 2020I really love these videos! I'm having trouble with the add user command though it doesn't work exactly like it does on yours. It keeps giving me a message back that I don't understand even though I typed it exactly like it was on your computer. I was even in the same pwd as you.
