Subject: Struggling with array searches/queries

I am reading delimited lines of data stored in array eg

123   name     address      date       product

I perform an array.each and then run an if statement based on the ID
(123). What I wish to do now is say

if you find ID 123
read the entries in name and count unique names

eg the entries bob bob mike sue
Would report 2      bob
             1      mike
             1      sue

I was thinking something like this

if id==123
  namelist.push name
  counts = Hash.new(0)
  if namelist.find {|n| (counts[n]) +=1}
    puts counts + name

Obviously the coding is not correct, but can anyone comment or expand
further on this?

Many thanks
