Greetings all!  I am new to the list so I apologize if this question is out of place because it is too basic.  I am taking a class at college on Linux.  We are completing a lab, and one of the questions was to determine how many hidden files there are in the /etc directory.  I found the answer using:
ls -a 
I am just wondering if there is a way to just display the hidden files.  I tried using:
ls -a | grep .*
but it seemed to ignore the . and just display everything.  I tried several other things as well, but everything seemed to just ignore the ".".  So, does anyone know a way to just display the hidden files in the /etc directory?  Thanks for the help.
