Real-World DevOps Project From Start to Finish - Linux File Permissions

The video tutorial explains Linux file permissions, focusing on the text and numerical methods for setting them. It begins with an introduction to file permissions, detailing how to identify directories and files. The text method is explained with examples, followed by the numerical method, which assigns numbers to permissions. The tutorial concludes with a warning against using 777 permissions, which allow unrestricted access.

What does the numerical method for file permissions represent, and how is it calculated?

Why is setting permissions to 777 discouraged in Linux?
