OS X : How to see the hidden folders using Finder

We all know that OS X is based on FreeBSD i.e. a flavour of Unix. So you can use command line along with GUI to browse folders. But you can notice that the folders that you can see using Finder are not exactly the same as those you can see using the command line or Terminal.

When you open the Finder window, you see the options to view iDisk, HD of your machine, the Home folder for the current user, Application etc. If you open Terminal and type pwd, you are in the home folder of current user under the Users folder. If you go to the root folder you can see many more folders than you can see using your Finder. Thus using the Terminal, you can see bin, dec, etc, sbin i.e. the Unix folder structure.

So what would you do if you want to see these Unix folders using your Finder. The answers is rather simple.
1. Open the Finder window.
2. Open te Go menu.
3. Select Go to Folder
4. Type in the name of folder you want to see in the Finder such as /usr or /bin.
Now there is a catch. You cannot directly see the root folder by typing '/'. But you can see any folder under root, which is a good news right?
