This guy is amazing. I learned a lot from Eli before I started my journey in the IT industry back in 2017. I have been jobless for about three years now, but I’m about to apply again for an IT staff position. Several companies require qualifications for a better understanding of Linux or more advanced knowledge. It took me about 4-5 hours to finish all of his 9 video tutorials to wakeup and refresh the learnings i had before. Even though the videos are old, they are still very effective. Thanks Eli! the best!
I salute you. Two things, its different when you know something and you are able to pass the same knowledge to others. your teaching is exceptional. My instructors in school makes it much more complicated and hard. But watching your video Eli has made life much easier for me . thank you once again.
#respect to your teaching skills. Some teacher make subject complicated and hard to understand but some teachers make complicated subject soo easy to understand you are one of them
Dear Eli, this is the best RUclips video. I refer to this video almost every month :) I cannot memorize the commands, that is why I use this as a reference ... Many thanks for posting this.
Why cant I find a teacher like you at my school? Your amazing, your knowledgeable, but also know how to translate the knowledge to those hoping to aspire to greater heights. I am very grateful I found your channel, simply amazing!
Eli I have watched almost all your videos but this is the first one I am commenting on. YOU ARE AMAZING. REALLY!! Thank you so much for these very informational and easy to understand videos. All the people disliking your video are crazy. Keep up the amazing work!!
Eli, this video is very helpful. I have been promoted to backend administrator on a Minecraft multiplayer server about a year ago. That server runs Linux. Before I was promoted, I had never used Linux before. Since then, I have found this video, and have checked it several times again during the year. Thank you for making this video!
I found the explanation by Douglas Rumbough very simple. linux permissions are in sets of 3, USER|GROUP|EVERYONE so to give a test.txt permissions you just remember the following: R =4 w=2 x =1 NONE = 0 you want USER(owner) to have all permissions 4+2+1 = 7 you want GROUP to have read+write 4+2 = 6 you want EVERYONE ele to have no permissions 0+0+0 = 0 so your permissions for the test.txt would be 760
I am switching to Ubuntu from Windows. I love it. File Permissinos were a little confusing at first. Eli, in this video alone, you have made it VERY clear to me. Thanks!
Thank you Eli. I'm also based in Maryland, and currently taking a Linux System Engineering class and this video really helped me understand user and group management and user/group permissions. Thank you.
Thank you SO MUCH! I've been dealing with this issue for years (no exaggeration) because (now I see) I'd started with wrong asumptions. Superb explanation! Thx again!
Thanks for your videos. I am just an IT hobbyist (I am my family's IT guy), but I am learning a great deal from you. You also should continue to explain how you make money. I now make sure to let all of your ads run through so that you can get the add revenue from them.
Dear Eli Thanks for these wonderful clips I'd like to come into the Linux world but highly doubt that,When I found this RUclips Channel It was a miracle for me.Thank u
I agree with you Eli, Linux "IS" really simple. Most Windows users freak out when they hear Linux, and the number one reason...THE COMMAND LINE !! You are demonstrating that the CLI is NOT the monster that it is made out to be. Fantastic Work on your part. One suggestion though. Please get a better writing utensil and move at least to the center of the writing board. Its frustrating watching you run out of room.
just as a little flavor for anyone that might be wondering why adduser defies the naming convention of thing+action, adduser is basically an overlay that sits on top of another command (drumroll): useradd. in some scenarios it's really just a perl script and not an independent command. makes the process a little easier though, so it is pretty common. the important takeaway being that adduser isn't on every installation image (especially minimal varieties), in case you're trying to invoke it and it isn't working. Most official repos contain the package though, so all you have to do is install it with whatever package manager you're distro uses.
The stickybit on a directory prevent users from deleting each others files. Example chmod 1777 /tmp means that if you create a file in /tmp , only you can delete it. To clarify, the permission of a file allow or prevent others to read execute or edit the file, but the permission of the directory allow or prevent creation, rename and delete of a file.
From ELi's lessons learnt from 2010: don't buy a huge whiteboard size 2 meter on 4 meter on which you write everything 30 cms from right side, OR, buy a longer power cord for your camera :-)
Great video ! The pronunciation, info , & capture is great. Instead of crudely drawn cmds, your newer videos could start out with the cmds already typed out or drawn out. Then roll into the over view of what the video is about. This is a basic video but for someone looking for specific info, if they didnt see a cmd in the 1st 5 seconds they could move on to your next video faster. Once again, great video, just 50% less face time
You can set multiple groups or users to a file if you use ACL's. The command is setfacl and the syntax is a bit hard for beginners, but you don't use the command line to do this in windows either, you use a file manager, and you do the same in GNU/linux to make it simple.
God love's you and will bless you for using the talent He gave to you to bless others. The topic is well explained by you and you give all details of everything topic you pick on. You are a Linux genius.
press esc and type :q and enter to quit vim, or :wq for save'n'exit, or :q! to force exit and loose changes. In old vi, and sometimes in vim, it doesn't really show up, so just type that and it should work. Alternative for quitting vim is ctrl+zz (hold ctrl, press Z twice).
Your speech and articulation are great. I like the way you teach. I'm just a little curious. Did you film this inside of a bomb shelter from the old Soviet Union?
@thebigbigdaddy I don't touch tape drives with a ten foot pole.... They were a pain in the ass even when they were the best option... I find Hard Drive backups are the way to go...
Found it really nice, even though things work a little differently in CentOS which I am trying to learn. For example, the adduser command simply adds a user without asking for their password or full name as it does here (6:40).
this video is probably the most useful video on the entire internet. Thanks
we're in 2020 and this video is still the most useful!
@@yazidproduction haha! Thanks for the reply. I forgot about this. Gonna give it a rewatch.
Very true thanks
and we're now in 2024 and this video is still the most useful ! 😂
Best investment of 37 mins I could of made.. Thanks for taking the time !

Extraordinary experience. Your straight-forward style made all the difference. Thank you
Thanks Eli, this stuff's amazing. Can't begin to express how thankful I am for making this both free and public.

YOU ARE AMAZING. REALLY!!
Thank you so much for these very informational and easy to understand videos. All the people disliking your video are crazy.
Keep up the amazing work!!
As always you take something that professors make sound complicated and show how simple it is. Great job I would be lost without these videos.
Linux isn't my domain of working. I want to learn it. So, I'm a beginner and you explain this it well! Congrats
Amazing video, after 7 years in Linux I finally understand user, group, and permissions :)))) Thanks a lot, man!
Eli, this video is very helpful. I have been promoted to backend administrator on a Minecraft multiplayer server about a year ago. That server runs Linux. Before I was promoted, I had never used Linux before. Since then, I have found this video, and have checked it several times again during the year.
Thank you for making this video!
Still rocking, one of the clearest guides to user management and basics of Access control.
I found the explanation by Douglas Rumbough very simple. linux permissions are in sets of 3, USER|GROUP|EVERYONE so to give a test.txt permissions you just remember the following:
R =4
w=2
x =1
NONE = 0
you want USER(owner) to have all permissions 4+2+1 = 7
you want GROUP to have read+write 4+2 = 6
you want EVERYONE ele to have no permissions 0+0+0 = 0
so your permissions for the test.txt would be 760
my nigga...
Omg you guys! Ha
this is exactly what eli said in the video tho?
I am switching to Ubuntu from Windows. I love it. File Permissinos were a little confusing at first. Eli, in this video alone, you have made it VERY clear to me. Thanks!
Thank you Eli. I'm also based in Maryland, and currently taking a Linux System Engineering class and this video really helped me understand user and group management and user/group permissions. Thank you.
Linux may be "simple" if you know the codes. But it is NOT intuitive. These classes are very helpful.
Thank you SO MUCH! I've been dealing with this issue for years (no exaggeration) because (now I see) I'd started with wrong asumptions. Superb explanation! Thx again!
You are doing a great job Eli, you're a good teacher and a lot of IT folks don't have the patience for it. Thanks for what you do.
I had no clue what the permission does in Linux, but thanks to Eli now the concepts are clear :)
Thanks for your videos. I am just an IT hobbyist (I am my family's IT guy), but I am learning a great deal from you. You also should continue to explain how you make money. I now make sure to let all of your ads run through so that you can get the add revenue from them.
Dear Eli
Thanks for these wonderful clips
I'd like to come into the Linux world but highly doubt that,When I found this RUclips Channel It was a miracle for me.Thank u
Amazing. You are one of the very best teachers online. God bless you real good.
You are the man! By far the easiest video tutorials for Linux admin to follow.

The Best tut on users groups and permissions on youtube. Thank You Eli !

Got here after filtering like 5 videos and many documentations, you got me broo. i was able to do it..
Thanksss :)) :))
Eli - Helping me get ready for interviews since 2011.
I agree with you Eli, Linux "IS" really simple. Most Windows users freak out when they hear Linux, and the number one reason...THE COMMAND LINE !! You are demonstrating that the CLI is NOT the monster that it is made out to be. Fantastic Work on your part. One suggestion though.

I have learned more from you than my professor. Thank you for being so descriptive.

You're totally an awesome teacher. I've learned a lot from you
Nothing more than enough in the explanation!10x dude!
I just want to say that I am finding your videos an AMAZING resource! You are appreciated. Thank you.
Most best best, amazing tutorial about linux permissions ever exist, Thank you alot!
Much better explanation than the Ubuntu server book!
The stickybit on a directory prevent users from deleting each others files.
Example chmod 1777 /tmp means that if you create a file in /tmp , only you can delete it. To clarify, the permission of a file allow or prevent others to read execute or edit the file, but the permission of the directory allow or prevent creation, rename and delete of a file.
Best teacher ever. Thanks so much Eli
excellent!!! love the white board, thank you so much. The best tutorial video I have seeing!!!
Awesome Video..This guy is know how to teach people...!!!!!!!Hats off to you...
From ELi's lessons learnt from 2010: don't buy a huge whiteboard size 2 meter on 4 meter on which you write everything 30 cms from right side, OR, buy a longer power cord for your camera
:-)
Simple and easy to understand. @Eli i must learn teaching skills from you... Thanks a lot.
Guy is the best teacher ever.
Thank you sir ! You have no idea how helpful this was for me !
This is one of the best instructional videos I have come across, thank you very much.
Hey this was a great vid. The 4-2-1 permissions thing was easily explained. Most books can't do it as well.
Could not be explained easier than this. Awesome.
Great video ! The pronunciation, info , & capture is great. Instead of crudely drawn cmds, your newer videos could start out with the cmds already typed out or drawn out. Then roll into the over view of what the video is about. This is a basic video but for someone looking for specific info, if they didnt see a cmd in the 1st 5 seconds they could move on to your next video faster. Once again, great video, just 50% less face time
Eli, thanks. I installed Linux years ago; however, I always used the graphical interface. It is great to be learning the terminal command lines.
You are good dude, your explanation is very easy to grasp. thanks eli
Wow! I just stumbled onto this video while I was configuring my first server. Thank you! Extremely helpful.
You can set multiple groups or users to a file if you use ACL's.
The command is setfacl and the syntax is a bit hard for beginners, but you don't use the command line to do this in windows either, you use a file manager, and you do the same in GNU/linux to make it simple.
Eli is a great instructor/teacher, like from me!
U r EXPLAINATIONS ARE VERY CLEAR SIR
THANK YOU FOR AMAZING LECTURES
much better than what i learned in college , thank
Great Job man ya spot on with it all, great to see someone teaching new Linux users the rope's
Great video explained brilliantly! Hats off to that guy!
I love how he feels the need to keep saying how 'simple' things are. As if just by saying so, that's somehow going to magically make it so.
God love's you and will bless you for using the talent He gave to you to bless others.
The topic is well explained by you and you give all details of everything topic you pick on. You are a Linux genius.
such a lovely teacher..hats off..
Nicely explained, liked a way of explanation👍👍👍👍👍
i really like the way you explain all the concepts.
Amazing instructor, let me know if your ever in London, would like to buy you a drink for all your support. Keep it up.
Thanks man, cleared a lot of crap my teacher told me in my head
press esc and type :q and enter to quit vim, or :wq for save'n'exit, or :q! to force exit and loose changes. In old vi, and sometimes in vim, it doesn't really show up, so just type that and it should work. Alternative for quitting vim is ctrl+zz (hold ctrl, press Z twice).
Hi ELi thanks for all your videos,,i follow al your videos and is really very helpful throughout. Thank you very much
Very good presentation skills.....keep you the good work and try come up with more complicated topic so it's easy to understand from you. :)
Your speech and articulation are great. I like the way you teach. I'm just a little curious. Did you film this inside of a bomb shelter from the old Soviet Union?
Simple and clear, you did a good job.
Awsome and very simple to understand User , Group and permission...
Thanks for all the information, you make this very easy to understand.
@thebigbigdaddy I don't touch tape drives with a ten foot pole.... They were a pain in the ass even when they were the best option... I find Hard Drive backups are the way to go...
very useful, Eli. I am learning from your videos to prepare an interview :-) Thanks!
Its an excellent tutorial series i have come across
Great explanation, you are really an excellent teacher
Just noticed the amount of videos on your channel is giving everyone full permissions (777)
Thank you for the clear explanation! Your videos are incredibly helpful!
You are a VERY good teacher! :)
Thank you so much Eli it was great, I was so confused but with this video, penny dropped 😅😅😅

Great video! Easy and well explained. Thanks!
I love your videos. You are very clear explaining. Thank you.
Found it really nice, even though things work a little differently in CentOS which I am trying to learn. For example, the adduser command simply adds a user without asking for their password or full name as it does here (6:40).
Thank you very much for such an informative video. Nicely done sir.
