Here's a Ruby script. You will need to apt-get install ruby to use it if
Ruby is not already installed. (I did it in awk as well, but the Ruby
solution is much easier to read.)
#!/usr/bin/env ruby
dataset = ARGF.inject([]) do |arr,line|
arr << line.scan(/\w/).inject([]) do |row,word|
row << word
end
end
print dataset.transpose.map! { |row| row.join("\t") }.join("\n")
puts ""
} thanks,
