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 am in a path of discovering Linux, and i must say your explanation was tremendously helpful and straight to the point. I have gone to your other videos and concise and straightfoward i found them to be. Thanks a lot.
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.
I was gifted a laptop running mint 20.3 and I have never touched it also been put of the it loop for years. This one video made me feel like I actually can do it and enjoy it again. Unreal mate you rangled my brain and for that you are showered in blessings thank you merry christmas 😂😅😊😊😊😊
THANK YOU VERY MUCH i learn a lot and also i cant wait to share i learn from you from my classmates next month im going to present Configuring Accounts in Linux wish me goodluck
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.
Great video, well explained thank you! I came here because I'm learning about security and figured I need to learn Users. I'm interested in videos on how to protect against vulnerabilities (CVE's) that are being found with scan tools like NMAP. Besides using difficult passwords and updating, I guess there is more to do. Just subscribed!
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.
"...ridiculous large font..." you say. I say "100% adequate for any CLI tutorial" keep it up. Also, when are you going to make a video on setting up ip addresses (static and dynamic) for Ethernet and WIFI? pretty please!
Oh thanks you very much for this vidéo. So i just install Linux MINT Cinnamon 21.1. There is a tool on system parameter window called users and groups. Is it the visual tool assigned to do it ?? And if yes ? How could use it to manage permission for different user on same workstation (limited folder access by example) ??
@Terminalforlife (LL) Cat can also show line number . Like this $ cat -n FILE Or if you want number of lines without the text do this . $ wc -l FILE No need to redirect file to stdin
i deleted user both ways but it still shows up under ls -l /home directory unlike in the tutorial. Cant figure out why? If I issue cat /ets/passwd the account doesnt exist.
Hello! could you help me with a little problem in my ethical hacking learning path when shell user is /usr/bin/php what does it means? expecificly about privilege escalation in this case. thanks for the videos!
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. :-)
I need to check the user behavior on Linux by using scripts on different parameters like user input by using tying. Any one having any script or where i will be able to find that ?
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
lol, this made me laugh. I had the same question in one of his other videos ... but I didn't ask it, instead I replayed that part of the video, over and over ... until I finally realised he said "is proudly sponsored by". Looks like we have the "same ears".
I am a power user and I have to tell your lesson is better than a lot of books out there. Keep it up Sir!

I think this channel is the best channel for learning linux system administration!
This is the best Linux-adviser channeI I have ever seen. Congratulations Keep up with the nice work!

Exactly, starting out as a complete beginner all the irrelevant comments really "helps" alot, not... 😂
I love the comments mocking people for giving their input. Even better if they type a whole paragraph to make a point.

Thanx man , This was a great video about user management in linux
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.
He also got a home directory in /home .
Unlike other system users .

Thanks Jay! Your presentations are clear and concise. This video is fantastic!!!
Thank you for the tutorial, Jay.
Thanks Jay. That's an amazing informational summary video.
Great video! Thanks a lot. Looking forward for the cron video.
Watching this videos again after a month. I fell I keep getting better from practicing what's in these videos.
Thank you for the large font. I like your way of explaining. Please provide Rhce and other certification courses

Thank you for sharing your knowledge and spreading the Linux Love! Great content, great tutor!
Thank you Jay! Awesome as always.
thank you so much for the all detailed explanation!
"...ridiculous large font..." you say.
I say "100% adequate for any CLI tutorial" keep it up.
Also, when are you going to make a video on setting up ip addresses (static and dynamic) for Ethernet and WIFI?
pretty please!
Hello man, welcome to you.
Hate to make the comment count exceed 69, but this was a nice video.
Thank you so much, Jay. Learning quite a bit from this series
aha!, a bonus command out of nowhere, thank you subbed and rewind.
Thanks Jay and yes X-Files was great.
Thank you for this kind of tutorials!!! Very well explained!
Thanks for this video with large font even its readable on my android phone
Great, informative video as always Jay.
I LIKE THIS FONT SIZE
Great, Jay. Thanks for the essentials.
Very informative, thanks
GREAT CONTENT!!!!
You are the best
Thank you for your support
Jay, Do you have a video that explains the difference between adduser and useradd?
Another excellent tutorial! thanks.
Great stuff!!!
Fantastic. Well done.
Oh thanks you very much for this vidéo. So i just install Linux MINT Cinnamon 21.1. There is a tool on system parameter window called users and groups. Is it the visual tool assigned to do it ?? And if yes ? How could use it to manage permission for different user on same workstation (limited folder access by example) ??
You can test it. Create a user ib command line and see if it shows up in the aop
Managing Users - that would be myself 😊
@6:14 I usually just do, grep -n "" /etc/passwd - as it saves the cat and wc steps.
@Terminalforlife (LL)
Cat can also show line number .
Like this
$ cat -n FILE
Or if you want number of lines without the text do this .
$ wc -l FILE
No need to redirect file to stdin
another great video! thank you!
I think I know the answer, but should the system user have it's own password too?
Nice presentation
Hi sir I want to ask what is the difference between useradd and adduser sorry I am a beginner.
The adduser command is actually a script that calls useradd but makes the whole process easier.
@@LearnLinuxTV OK, sir, I understand now, thank you for explaining
i deleted user both ways but it still shows up under ls -l /home directory unlike in the tutorial. Cant figure out why? If I issue cat /ets/passwd the account doesnt exist.
Hello!
could you help me with a little problem in my ethical hacking learning path
when shell user is /usr/bin/php
what does it means?
expecificly about privilege escalation in this case.
thanks for the videos!
this is telling that the user shell is php.
you should be able to run php when logged in this user
(checking my progress)
Thanks sir, 🙂
video start at 2:40 sec
Thank you so much appreciate you
what happens to the files and folders if you delete their owner user account ?
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. :-)
Would you write a book on arcolinux to update commands and distro ????????????
Thanks Jay
Thank you!
greetings and thanks from the "smoker"
what does that x signifies
Everytime i change users i get message of error saying « killed »
Thank you so much!
I need to check the user behavior on Linux by using scripts on different parameters like user input by using tying. Any one having any script or where i will be able to find that ?
30:30 sets the stage for the Y99999 bug
so for sysuser you got a UID of 998 and if its incrementing by one does that mean you only have 2 UIDs left for any other system users ?
It'll keep reducing like 998, 997, 996 ...
what is /bin/false in etc/passwd?
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
Thank you very much
Awesome vdei
thank you
Lol, ah sysuser is now on my home screen 😅
Useradd vs adduser
Edit: Adduser will be best for new users as it creates the skel user environments
Adduser is a script .
A script in perl prolang
Useradd is a program .
Written in c and compiled to machine code.
Here is a difference 🙂.
@@xrafter yes I am fast learning noob.
At the time easier to set --uid parameters and subsequent acls
What do you mean "is probably sponsored"?
lol, this made me laugh.
I had the same question in one of his other videos ... but I didn't ask it, instead I replayed that part of the video, over and over ... until I finally realised he said "is proudly sponsored by".

👍👍
lol you have a bunch of lines with the etc passwd i have 1
Wait so I can keep my brother from deleting my files without having to slap him in the face?
Yes
ummm... interesting thumbnail
x-files was on friday nights

Pfff.... Extremely un-user-friendly. 🙄
