Hi All,

Quick question:

I have CSV file containing account information. Each line contains has a unique account number and other information.

I need to parse the file for the last line for each unique account number. Sample data: 
account numbers=abc123 and xyz123

20080618,adfadf,adfadf,abc123,ljlkjll,
20080618,jfjfjf,bmbmbm,abc123,zzzdddd,
20080618,343434,959595,abc123,fjadfaf, <==parse
20080618,adfadf,adfadf,xyz123,ljlkjll,
20080618,adxxxf,gggsss,xyz123,ggaaddf,
20080618,dddfff,dfdfdd,xyz123,xxxxxd, <==parse

So what I need is a way to iterate through each line of the file and for each unique account number print out the last line containing the unique account number.

So for accont xyz123, I would want to the last line for that account. 
20080618,adfadf,adfadf,xyz123,ljlkjll,
20080618,adxxxf,gggsss,xyz123,ggaaddf,
20080618,dddfff,dfdfdd,xyz123,xxxxxd, <==parse

Any suggestion or idea on how to accomplish this, will be appreciated
