Subject: Re: Using 'uniq' question

Aha, thanks for #find, Joel. So the that would be:

-----

records = '100827   1000  1516
100792   1000  1698
100792   1000  1698'

record_lines = records.split "\n"

unique_records = []
record_lines.select do |line|
   first_n = line.split()[0]
   unless unique_records.find {|el| el.split()[0] == first_n}
     unique_records.push line
   end
end

sorted_records = unique_records.sort do |a,b|
   a.split()[0].to_i <=> b.split()[0].to_i
end

puts sorted_records

# 100792   1000  1698
# 100827   1000  1516

How to write that much more elegantly (more expressive and concise)?
