Hands down one of the best explanations on file permissions I've found on UA-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’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.
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.
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 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!
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 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.
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 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.
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!
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
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
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)?
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?
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?
This series doesn't feel like a crash course. It feels like the real effing deal. Thanks

Amazing Jay, your series connects to the real 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!

Love your content, btw. Even regular Linux users can pick something up from your videos.

And I don't :(
OK Reddit
Amazing. You just handed me exactly what i needed to hear to understand how permission works. Thanks
you are a absolute great teacher
As always, awesome video. Thank you Jay and greetings from Germany :)
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.
Wow!
The way you explain concepts is amazing and easy to understand.
going through a yellowtail-tech course for RHEL and this series has been a massive help on the side outside of class
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.
Thank you for all your help to the Linux community!!
All of your tutorials are clear and easy to understand and also very informative.
super helpful! instead on going through the linux command book i borrowed from uni lib, im going through these videos instead! thanks!
Great job, your teaching skills are excellent.
Very nicely explained, specially that -R one that was the hook point to be understood respect and regards from India.
Just loved your video and the way you explain the subjects
Glad you liked it!
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.
Learning more here then being slammed with textbook information. Thank you!
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)
Thanks!
love the pacing and the way you explained that !
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!
Great videos; they've been a great help. Thanks for all you do and keep up the good work!

I'm a linux beginner. I love your explanation
Best Linux channel
Thanks a lot Jay, greetings from Madrid.
This is a very esay to understand video. very detailed and simplified.
😊 🙏 😊
thanks for sharing this. great refresher.
Exactly what I need now. Thank you!
Great video Jay, more Linux tutorials please 👍
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.
Thank you jay! You explain all the concepts so easily!
Great stuff Jay!
awesome explanation jay, love your videos--keep 'em coming please
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!

Nice tutorial Jay very easy to follow and understand. Thank you
Superb explanation Jay. Thanks very much!
Great because exhaustive and well organized video, thanks for that.
Excellent Explanation Jay.Thank you so much.
Top job on explaining it mate! thanks for the informative vid
thank you sir this is so helpful and i found it fun to watch this video lot of support
You did an outstanding job on this tutorial
This video is awesome, am definitely recommending this. ❤️
Just what I needed. Excellent
Love your content and thank you so much for allowing us to learn more about linux =)
Very good informative video Thanks you very much for this, Looking forward for more videos like this
Thank you so much for this video Jay. This is amazing and easily understandable.
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.
Awesome video. I'm loving Linux.
Perhaps a follow on video covering mkdir --mode, umask, SGID bit, sticky bits?
Nice 👍🏻 thanks for sharing useful information. Subscribed 👍🏻✌🏻🇨🇦
Great lesson!! Bravo
Amazing video you demystified and made it very clear
easy to understand explanation 💙
Outstandingly presented.
Thank you, Jay.
Video is next level thanks jay
It seemed to a difficult task before but the video has made it more simple
You are my best teacher 😍
Another really great tutorial! Many thanks!
You are a great teacher, thank you so much.
What about sticky bits? What about sharing files and folders to many groups at once?
You are real cool man!!! Very clever! Thanks!
Very informative as always.
Love u, this was awesome video ❤ thank you so much 🎉
Now I get it, Jay!
Numerical value for chmod makes sense if you know about "Bitwise flags"
This was very helpful, thank you.
Awesome explanations
A useful and very well done video thank you sir!
Thank you very much for the tutorial.
this is amazing. THANKS!
Thanks - great vid - nice and clear.
I didnt go to class, watched this video, smoked weed, went for the test and got an A. :) easy life. thank you
Loved it :)
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?
Thank you Jay!
Thank you; it's very educational.
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?
Permissions gives me issues from time to time. Eg groups like backup. Thanks Jay
Great video 🙌🙏
love this video, thanks
Thanks Jay
So, what permissions are best for the home directory? 700?
Ubuntu has switched to 750 for the home directory
