symbol count in a text file [iptables log]

[M.W. Chang]

I could figure this one out. but how to list all possible combinations 
of DPT=9999 in a text file? There should be an existing shell util that 
will do something like this:

select distinct DPT=* from textfile

then I need to direct each combination into a file and apply wc on it to 
produce a distribution

> grep DPT=9999 /var/log/messages | wc
