Thank You ! Am glad that you liked it.

Your understanding is correct. But there is a very thin difference between 600 and 700 . Please visit the stackoverflow link that I have pasted. It will help!

Hi Shivaraj thanks for your attention to details. Your understanding is correct however, it is the right permission. 600 means only the owner of the file has full access not others. Please refer to this: https://stackoverflow.com/questions/50735833/what-is-the-difference-between-chmod-go-rwx-and-chmod-700#:~:text=It%20will%20not%20change%20permissions,no%20matter%20the%20previous%20permissions.

Thanks !
