Seams like you´re not very firm on using unix command line.

A Tip for Windows users....

Maybe you want to try WinSCP http://winscp.net/eng/download.php. It´s a Windows Programm that allow you to connect to Unix PCs via SSH and browse and edit the file in a grafical enviroment.
Just walk through the directorys by mouseclick and open a file with doubleclick, to edit it.

This is much easier for Windows Users. I think there are also Programms like that for Mac Users.
