I know this is for CentOS stuff, but I'm at a loss on how to build a 
script that does what I need it to do.  It's probably really logically 
simple, I'm just not seeing it.  Hopefully someone will take pity on me 
and at least give me a big hint.

I have a file with two columns 'email' and 'total' like this:

me at example.com 20
me at example.com 40
you at domain.com 100
you at domain.com 30

I need to get the total number of messages for each email address.  This 
type of code has always been the hardest for me for whatever reason, and 
honestly, I don't write many scripts these days. I'm struggling to get 
psuedocode that works, much less a working script. I know this is off 
topic, and if it gets modded out, that's fine.  I just can't wrap my 
brain around it.
