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.

How 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.
@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!"
It is a great tutorial man!
Thank you a lot!
You are my favourite Linux teacher!! They are actually the geekiest and funniest! Thanks for your informative videos which I thorougly enjoyed.
ty
Good stuff!
Any reason why a black box sometimes appears? Is it related with security?
I can hear your server room in the background ;).
how do I get that bottom bar you have that gives additional stats?
This man is prophete
Finally learned how to run terminal in root mode. Getting prompted for password every time was annoying! Thanks
God this tutorial is so good.
"rm -rf /home/schnerg/"
I too like to live dangerously 😛
Awesome videos!
Nice 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
It'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
I got a lot of good stuff from this video. Thank you.
whats the significance of tailing those three files? which one shows what? shadow shows exclamation marks but passwd doesnt? Then whats the point of checking out etc/group?
Sir your tutorial is great godbless you 🙂
How can I restrict users to access only few things especially for mca students

this guy really understands the concept of open source…….#knowledge is free #knowledge is for everyone
99999 days are 390 years
Great tutorial, thanks 😉 Greetings from PL
Watching your series now.. Appreciate the work you put into these.
im 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)
if root want to give access file to a user.
How do I do that?
Do you have updated vids?
As 'Man useradd' shows there is now an updated command which is 'adduser'?
You are awesome!!! Love the way you explain things. And now I shall continue binge watching the rest of this course ><
I 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.
You make the best linux tutorials i know. Want to see more console windows 😉
