[newbie] How to search for greatest # of incidences?

[Ronald J. Hall]

If I had a text file that contained the winning Powerball numbers in our state 
for the last 10 years, what would be the easiest way to search it for the 
numbers that occurred the most often. Hopefully output to a text file, in 
descending order by rank?

Can I do that from bash?

Thanks!
