Date: 2012jun11 OS: Linux Distro: RedHat/Fedora/CentOS Q. What's that extra dot in my "ls -l" listing? A. It means there's a SELinux context on the file. For example:

ls -ld /tmp

on my Fedora box gives:

drwxrwxrwt. 33 root root 50176 Jun 11 10:37 /tmp/ ^ Special SELinux stuff is present

A plus (+) in that position indicates an ACL (Access Control List)
