Issue

• Why does ls output come up with a dot following the file permissions in Red Hat Enterprise Linux 6?

  $ ls -ld test
  drwxr-xr-x. 2 root root 4096 Feb 14 18:14 test
  

• Why do some files not have the dot (.) whilst some others have it?

  [root@localhost ~]# ls -l
  total 64
  -rw-------. 1 root root  2636 Feb 17 02:46 anaconda-ks.cfg
  -rw-r--r--. 1 root root 41179 Feb 17 02:46 install.log
  -rw-r--r--. 1 root root  9154 Feb 17 02:44 install.log.syslog
