how to get only hidden files in UNIX?



In unix/Linux hidden files typically starts with a period  i.e. namely dot ('.')

In order to get hidden files we need to use the " -a " option with -d as well  and with regular expression ".*" .

If you want only files starts with dot (".")i.e. we have to use grep command as  grep "^-" as below.
Hidden Files and directories:

 [root@www ~]# ls -lad .*
