How to show hidden files on OSX

Sometime it is convenient to use  Finder instead of Terminal to copy files. 

The default Finder behavior is not to show hidden ( dot files ). 

To change this behavior, open your Terminal::

  defaults write com.apple.Finder AppleShowAllFiles YES

Then restart the Finder.

How to restart the Finder ?? ::

Hold down the 'Option' key then click on the 'Finder' icon on the Dock, Then click 'relaunch'.

*#* Warning :: CAUTIONS with the DOT files you see. DO NOT DELETE/MODIFY UNLESS YOU KNOW WHAT YOU ARE DOING !!!
