Lesson 19. Configuring Permissions in Unix

In this lesson, you will learn about how to configure and manage user permissions in Unix.

Wow, we have just worked through 18 lessons on how to configure Unix and we are still going strong. In the last part of this book, I will attempt to fill in some gaps in the material we just covered. For example, we talked about how the ls command when used with the l option would provide a long listing of the files in your current directory. We briefly touched on how to read the output from the ls l command and how it had shown the set of permissions associated with each file or directory. Now, in this lesson, we will learn more about those permissions and how to configure and manage them.
