As a Linux Server Administrator, it's your job to keep an eye on your users - and in this video, I'll show you how to add and remove users. Also, I'll show you how to change the password of your users. In addition, we'll go over a quick summary of the /etc/passwd and /etc/shadow files.

Historical note. GECOS is pronounced "GEE-kose" and refers to the General Electric Comprehensive Operating Supervisor, a mainframe OS dating from the 1960s. GE later sold their mainframe business to Honeywell, who dropped the "E" and called the OS GCOS, General Comprehensive Operating Supervisor. I worked on a GCOS system in the late 70s and early 80s. Some early Unix systems at Bell Labs used GECOS machines for print spooling and various other services, so this field was added to carry information on a user's GECOS identity. GCOS was a good OS to work with and had some Unix-like features. Thanks for the fine video, keep up the good work!

I love all the people in the comments attempting to "correct" you and point out there are more efficient ways to run some of these commands. Guys. This is for beginners. Going step by step and walking through each command one at a time. Could he have used cat less? Sure, but then he'd have to explain more commands. Why pollute the explanations with more command explanations when the topic is about user account management.

Any chance of doing a series about using freeipa and smartcards/yubikeys to do standard logins? You are what I am trying to be, but things like the PAM settings are hard to work with and some of us are trying to advocate for more linux, less windows environments. Something like that would go a long way. GREAT content by the way, love everything you do.

And if yes ? How could use it to manage permission for different user on same workstation (limited folder access by example) ??

I've got a question about permissions. Let's say I have Node running on a Linux server and have a CLI that will use Node to run other system app commands like wget or git. If I add a user and allow that user to execute the CLI only, would the user also need access to those other app commands? What I want to avoid is letting the user use any other apps other than the one CLI to do anything on the server. Is this possible? I guess I could go and experiment, but I thought I'd be lazy and ask. :-)

Hi, I just started to learn & I follow every vid you release. I tried this proxmox thing and after a few re-installation because of crash/freeze up I wantet to save an image over to my truenas. Proxmox 7 will not let clonezilla copy anything. It fails every time. Have you tried it lately? And hopefully an solution. Cheers

Good example why it is a good idea to explicitly mention all the options is at 22:40. As you can see system user got a shell. Which is not a good idea I think.
