Distribution aggregation

I needed to plot distribution of timed events today and ended up with the following Ruby script to prepare the csv data:

data = {}

while gets() do
  $_.split().each do |item|
    inum = item.to_i
    if data[inum]; then data[inum] += 1; else data[inum] = 1 end
  end
end

data.keys().sort().each do |key|
  puts "#{key}, #{data[key]}"
end

Here is the usage example when this script saved as distr executable:

$ echo "1 4 235 3 2 3 1 4 2 3 4 1 2 45 6 3 2" | distr
1, 3
2, 4
3, 4
4, 3
6, 1
45, 1
235, 1
$

As with any gets-based script, it takes filenames as parameters as well.
