I’ve been using Linux for quite a while. Nothing too extensive - just home use for a media server and file share server. I’ve seen a lot of videos. This is one of the best I’ve seen. To-the-point, clear explanation and informative. Great job.
Hands down one of the best explanations on file permissions I've found on TH-cam 👐🏾. I initially had a problem with using the octal notation to change file permissions but your explanation made everything so clear. Thanks a lot for this great learning resource 👏🏾
I LOVE your videos... you make it UNDERSTANDABLE-- no fluff, no muss, no BS. just the facts- and no Um - ah- well maybe- or normal chatter-- PERFECT videos!!! THANK YOU.
I just logged into my yt account to say this is a masterly class! perfectly understood for a beginner of linux like me, i can only say im very thankful to you!
As someone who has been learning linux trying to understand the linux filesystem has been hard especially coming from a windows background. Network chuck just dropped a video on this very subject and now you, awesome 👌
I was trying to explain linux file permissions to somebody at work and left them stumped. So now i'll just link them to your video. You did 1000x better job of explaining.
I am very impressed by the way you teach these topics. would be also interesting to learn more about attributes / capabilities, as far as I understand, devs are held to replace the usage of the setuid permission and to switch to capabilities instead.
man you;r amazing. Im done wrong school and now im little bit busy, working etc and have fmily so i can't go to school but on this channel is everything what i need. This channel is more practice not only distro hoppings reviews. This is what i wanted and thats why i subscribe ur channel. You and ef-tech linux made simple are the best channels for ppl who wnt to learn linux and deep dive :)
I have been using Linux for two decades now. I still like watching your videos in case I have omitted something in my education. Lo and behold at the very end of this video, you taught me about chown $USER: I never knew I could have a naked colon and it would use the user's default group. Thank you for all of your videos.
Amazing video as always Jay but I think you should have included about SGID,SUID and Stickybit permissions too as they are often asked and not a lot of videos cover them
Just discovered your channel and I absolutely love it! Love your presentation and approach to each topic. I'm picky when it comes to instructors and you definitely have my stamp of approval!
19:05 but what about if user (jay) has no execute permissions, but group (jay) has execute permission? Why is it "permission denied", if the user "jay" is in group "jay" (which has the execute permission)?
Hay JaY! I struggle with this all the time so I keep a cheat sheet with some of this printed out. Although I have watched others explain this topic I will say you did a better way for me to understand it a bit better... :-) So thank for that. Did know about the -R for files but did not know you could use on a directory like that... :-D Cool! So Thanks for the video! LLAP
Is there an actual use case for those odd permissions (like being able to write but not read)? It seems to me like permissions should be hierarchical. Like, being able to write to a file should necessarily mean you can also read it. Or being able to read the contents of a directory implies being able to access it. Are counterintuitive permissions just a quirk of how chmod was written that can't be changed now, or do they exist for a reason?
Wanted to learn this specific stuff because www-data was causing having on docker. added my other users to www-data and www-data:root was the answer to anyone looking to mount a partition inside docker container which has access denied.
While chmod does not have an -r option, many other commands do. So commands always use -R for recursive, to be consistent with general practice, and to avoid mishaps.
I have one question - What if you make a group including the user1 and user2, and make a file with chown user1:group that_file. (the permission is -rwxrwx---) Now, can user2 access that file directly? Or is there any procedure to invoke the usage of the 'group' Identity?
In the TV show Mr. Robot, the main character runs the command "chmod -R ER280652 600". (There may have been more to the command but it cut away.) What does it mean?
This series doesn't feel like a crash course. It feels like the real effing deal. Thanks

Learned more in this half hour video then my professor taught me in a 3 hour lecture. Thank you very much. Liked and subscribed.
I LOVE your videos... you make it UNDERSTANDABLE-- no fluff, no muss, no BS. just the facts- and no Um - ah- well maybe- or normal chatter-- PERFECT videos!!! THANK YOU.
The best video on Linux permissions available online. Period.
Jay! You explain Linux better than anyone on the internet. I appreciate your service to the community : )

All of your tutorials are clear and easy to understand and also very informative. we need more people like you in the world. thank you
Wow, finally I won't have to blindly add sudo when I get "Permission denied". Thanks so much this is pretty clear!
your tutorials are so real and straight forward ,thanks for the good job
you are a absolute great teacher
going through a yellowtail-tech course for RHEL and this series has been a massive help on the side outside of class
“Permissions can be a BIT tricky...” lol I see what you did there
Love your content, btw. Even regular Linux users can pick something up from your videos.
🤓

And I don't :(
OK Reddit
Awesome Linux tutorial video! really appreciated!!! spent hours learning and love your clear teaching method! shared this with mates and family!
Amazing Jay, your series connects to the real world. Thank you❤️
All of your tutorials are clear and easy to understand and also very informative.
Amazing. You just handed me exactly what i needed to hear to understand how permission works. Thanks
Best Linux channel
Wow!
The way you explain concepts is amazing and easy to understand.
I am very impressed by the way you teach these topics.
would be also interesting to learn more about attributes / capabilities, as far as I understand, devs are held to replace the usage of the setuid permission and to switch to capabilities instead.
Thank you so much, Jay. Fantastic video.Would like to see more about the SGID and SUID permissions and umask and maybe a sticky bit as well.
Very good video. I'm on Chap 17 of the Linux OS Essentials course and this one helped me a lot in understanding some of the concepts.
super helpful! instead on going through the linux command book i borrowed from uni lib, im going through these videos instead! thanks!
Learning more here then being slammed with textbook information. Thank you!
man you;r amazing. Im done wrong school and now im little bit busy, working etc and have fmily so i can't go to school but on this channel is everything what i need.

Thank you for all your help to the Linux community!!
Just loved your video and the way you explain the subjects
Glad you liked it!
love the pacing and the way you explained that !
I'm a linux beginner. I love your explanation
As always, awesome video. Thank you Jay and greetings from Germany :)
Glad I could just search up this video and refresh my memory on what the output of `ls -l` is . Totally forgot what each symbol stood for.
Very nicely explained, specially that -R one that was the hook point to be understood respect and regards from India.
Thanks!
I have been using Linux for two decades now. I still like watching your videos in case I have omitted something in my education. Lo and behold at the very end of this video, you taught me about chown $USER:
I never knew I could have a naked colon and it would use the user's default group. Thank you for all of your videos.
😊 🙏 😊
thanks for sharing this. great refresher.
Great stuff Jay!
Amazing video as always Jay but I think you should have included about SGID,SUID and Stickybit permissions too as they are often asked and not a lot of videos cover them

Great job, your teaching skills are excellent.
Just discovered your channel and I absolutely love it! Love your presentation and approach to each topic. I'm picky when it comes to instructors and you definitely have my stamp of approval!
This is a very esay to understand video. very detailed and simplified.
What about sticky bits? What about sharing files and folders to many groups at once?
It seemed to a difficult task before but the video has made it more simple
Perhaps a follow on video covering mkdir --mode, umask, SGID bit, sticky bits?
Thank you so much for your great video! I've been enjoying watching it, and learned a lot. Now I have more questions about Unix permissions)
Exactly what I need now. Thank you!
You did an outstanding job on this tutorial
Thanks a lot Jay, greetings from Madrid.
Great videos; they've been a great help. Thanks for all you do and keep up the good work!
Thank you jay! You explain all the concepts so easily!
Great video Jay, more Linux tutorials please 👍
Just what I needed. Excellent
So, what permissions are best for the home directory? 700?
Ubuntu has switched to 750 for the home directory
Nice tutorial Jay very easy to follow and understand. Thank you
Numerical value for chmod makes sense if you know about "Bitwise flags"
thank you sir this is so helpful and i found it fun to watch this video lot of support
Superb explanation Jay. Thanks very much!
Great lesson!! Bravo
easy to understand explanation 💙
Great because exhaustive and well organized video, thanks for that.
Thank you, Jay.
Now I get it, Jay!
Excellent Explanation Jay.Thank you so much.
Permissions gives me issues from time to time. Eg groups like backup. Thanks Jay
Top job on explaining it mate! thanks for the informative vid
awesome explanation jay, love your videos--keep 'em coming please
Amazing video you demystified and made it very clear
You are real cool man!!! Very clever! Thanks!
Outstandingly presented.
19:05 but what about if user (jay) has no execute permissions, but group (jay) has execute permission? Why is it "permission denied", if the user "jay" is in group "jay" (which has the execute permission)?
My guess is it's basically carving out an exception. Users in this group can all execute, except for this specific user.
This video is awesome, am definitely recommending this. ❤️
Awesome video. I'm loving Linux.
Video is next level thanks jay
Hay JaY! I struggle with this all the time so I keep a cheat sheet with some of this printed out. Although I have watched others explain this topic I will say you did a better way for me to understand it a bit better... :-)
So thank for that. Did know about the -R for files but did not know you could use on a directory like that... :-D Cool!
So Thanks for the video!

How about setting different permissions and ownership for multiple hard links to the same file?
Very good informative video Thanks you very much for this, Looking forward for more videos like this
Nice 👍🏻 thanks for sharing useful information. Subscribed 👍🏻✌🏻🇨🇦
You are my best teacher 😍
what are the 1;2;3 before the jays?
Love your content and thank you so much for allowing us to learn more about linux =)

Are counterintuitive permissions just a quirk of how chmod was written that can't be changed now, or do they exist for a reason?
You are a great teacher, thank you so much.
Any chance you could explain how to edit permissions for /usr/share ?
what owner:group should I set my lampp(apache and mysql) folder, so a non sudoer user can execute it without sudo command?
Wanted to learn this specific stuff because www-data was causing having on docker. added my other users to www-data and www-data:root was the answer to anyone looking to mount a partition inside docker container which has access denied.
Hey Is there a difference between chown : to change a group and the command chgrp
I looked at the man page for chmod. Why is recursive option -R and not -r?
was wondering the same thing
While chmod does not have an -r option, many other commands do. So commands always use -R for recursive, to be consistent with general practice, and to avoid mishaps.
I have one question -
What if you make a group including the user1 and user2, and make a file with chown user1:group that_file. (the permission is -rwxrwx---)
Now, can user2 access that file directly? Or is there any procedure to invoke the usage of the 'group' Identity?
Another really great tutorial! Many thanks!
In the TV show Mr. Robot, the main character runs the command "chmod -R ER280652 600". (There may have been more to the command but it cut away.) What does it mean?
indeed linux permissions can be bit tricky. Finally I get the reference lol
How do you get different permissions for different users on the same directory?
Hi Jay, After changing the owner and user to batman, how "jay" user can still see Downloads contents with sudo?
sudo chown -R batman:batman Downloads
Loved it :)
Very informative as always.
Thank you very much for the tutorial.
Note: You cannot execute a file unless you can read permissions enabled. So, x on all files shall be accompanied with r.
Love u, this was awesome video ❤ thank you so much 🎉
