Working With Users and Groups (Linux Zero to Hero 2022)

Users and groups is a very fundamental thing to know how to work with when it comes to Linux. Users and groups are used for a variety of different things in Linux. The files used to configure users and groups can seem daunting at first, but I'll help you through it.

Hope you enjoyed the video!

This was actually happened to me, I commented every sudo user in sudoers file, saved the changed and forgot the root password on my office server :D Wish I would have watched such video 6 months ago :p

This video was amazing! Thanks a million for creating this video as I was able to refer several people. Your structure and flow is fantastic, keep up the amazing work : 💖

What an amazing video, I loved that you went through all the common scenarios which a beginner could face.

There is also adduser...

adduser: add user with full profile and info (pass, quota, permission, etc.)

useradd: add user with his name only (if you want to add a temp user with only a name, other info not required)

I feel like it's a stupid question, but an explanation of what a group actually is would make this better

I don't think I've ever seen you with a hat, you've been hiding some nice lettuce!

Didn't know much about /etc/shadow and managing other users on the system. Great video!

This video is great from my perspective. I've been messing around with UNIX and Linux stuff for many years but it has never been my main focus, so I have to re-learn many things many times. I'm about to switch over to Linux (maybe Pop!_OS) full-time so your non-fluff approach to teaching this topic is very helpful to me. A video on best approach to disabling root, or not, limiting sudo users, wheel, as related to hardening/securing a system, based on what you said in this video, would be helpful. Thanks for your work. You have a great teaching style.

It would've been great if you showed how to use sudoers.d files to give a user nopasswd sudo privileges to some (2-3) commands. That is VERY useful when working with service or power users. Thanks for the great vids! :D

5:43 Why didn't you show the hidden files with 'ls -la'? Especially in the skel dir. You're providing half information here (not just simplified).

[thedomaro]

that was really smooth, thank you dear

[MdShamimRahman]

Why did this series stopped? Maybe not a good question but I was wondering more step by step into advance stuff, securing system, controlling things and making life efficient by awesome commands. Thank you.

[MrTigerstyle]

Great video! I didn’t realize visudo checked syntax. Can this one segue into how / witch users and groups deploy software?

[anselmpeter]

It really helped me to get to know some important directors and some great commands. Thanks your content

[tkdevlop]

Great can you also link that vscode file in the description that would be a great help

Why do so many sophisticated Linux users pipe cat into grep instead of just using grep? @1:34

[DanelonNicolas]

A friend of mine is learning this.. thanks, super clear 👌🏻

[ashketchum]

This was really great and way more informative than anything google provided. I'd love to know more if you're willing.

Try to talk a little bit slower and do not answer questions no one asked.

Many things in this tutorial don't work for me.
First, useradd did not create a password for the user john, so I couldn't switch back to root as simply as you did (with a hotkey? I didn't see you type sudo -i to switch back).

Second, after I simply opened another terminal and went to root to change/create a passed for john and for the root itself, the command"useradd -m john" also didn't work for me at all as it assumes I'm trying to create a home for a new user, but since john as a user already exists then it can't execute this command.

I searched online a bit and learned that if you used useradd, instead of adduser, you can't really create a home directory.
I tried a few workarounds online to fix this:

1- useradd -m $john (didn't work)
2- useradd -m JOHN (created a completely different user and its home folder named JOHN)
3- A different workaround was creating a new dir using "mkdir /home/john" followed by "chown john:john /home/john" to make john the owner of that dir and then "cp -rT /etc/skel /home/john" to populate /home/john with default files and folders
All these solutions never worked.
The command "useradd -d john" still returns invalid home directory, meaning john still does not have a home folder.
