Question

The write permission for a directory determines that ____________

(a) we can write to a directory file

(b) we can read the directory file

(c) we can execute the directory file

(d) we can add or remove files to it

I got this question in homework.

My enquiry is from File Ownership and Permissions in chapter Basic File Attributes of Unix

Answer 1

Correct option is (d) we can add or remove files to it

The explanation is: The write permission of a directory does not imply that we can write to the directory. Only kernel is allowed to do that. It simply means that we can create or remove files from the directory.
