Quick note here, the pattern match you mention below is not considered a 
Regular expression but instead a "glob expression". 

The primary difference is that in a glob * means match any number of any 
characters, while in a regular expression it would be ".*" in other words 
having a period before the *. This is because regular expressions use all 
punctuation to mean something special 

The period is used to match any character.
The star means zero or more of the immediately preceding pattern (in this case 
. or any character).

Generally in UNIX like systems which terminal brings you to a bSD UNIX 
environment, most places where you are requesting a matching of file names u   
are using a glob pattern and not a regular expression. 
                Best wishes,
