Honestly, I found little tricky to understand the file system in the beginning but when you came up with that hotel example, it helped me to understand the entire concept of file system hierarchy in the wink of an eye with the help of such beautiful slides.

I had some hands on Linux commands prior watching it but literally -p command, I found it new for me and very useful to create parent directories along with sub directories in one go without getting an error. Amazing!

I don't how long I will last or tuned with this exclusive series but I confess that I enjoyed learning through your videos like never before in my life. And, yes, I strongly believe that the quality of your content and the interest of me in it will keep me bounded with the series till last.

Thank you, Kartik!
