Scripting Question

[Patton Echols]

I have a fairly massive flat file, comma delimited, that I want to 
extract info from.  Specifically, I want to extract the first and last 
name and email addresses for those who have them to a new file with just 
that info. (The windows database program that this comes from simply 
will not do it)  I can grep the file for the @ symbol to at least 
exclude the lines without an email address (or the @ symbol in the notes 
field)  But if I can figure this out, I can also adapt what I learn for 
the next time.  Can anyone point me in the right direction for my "light 
reading?"

By the way, I used 'head' to get the first line, with the field names.  
This is the first of about 2300 records, the reason not to do it by hand.
