Hi,

i'm new to ruby.
How  could i read a tab-delimted textfile  with two columns + header
row
and count the distinct values from the 2.column?


## my first experiments missed because i have  to elimnate the header
row!?#######

filename = gets.chomp
text = String.new
File.open(filename) { |f|  text = f.read }
values = text.split(/\t/)
freqs = Hash.new(0)
values.each { |values| freqs[values] += 1 }
freqs = freqs.sort_by {|x,y| y }
freqs.each {|values, freq| puts values+' '+freq.to_s}


Many thanks for a starting point.
regards, christian
