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.

Hands down one of the best explanations on file permissions I've found on YouTube 👐🏾. 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 👏🏾

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’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.

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.

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 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.
