Hello,
The permission of the "/home" directory is as below:
Code:

$ ls -l /home/
total 0
drwx------. 3 jason apache 170 Sep  8 20:33 jason

And below files exist in the home directory:
Code:

$ ll
total 304020
-rw-r--r--. 1 root  root          0 Sep  8 19:16 access_log
-rw-r--r--. 1 root  root    5970706 Sep  8 19:17 wordpress_access.log

"jason" can remove these files. is it because of that "jason" has permission on the "home" directory?
How can I understand a permission is "-R" ?

Thank you.
