Doesn't quite work...looping question

It parses, it opens, but it doesn’t write to the outFile. So I am
guessing I am not looping through the array properly.

#!/usr/bin/ruby -w

populate the array

kw = [ “adult”, “teen” ]

create a file to append data found from the input file

inFile = File.open(ARGV[0], “r”)
outFile = File.new(ARGV[1], “w+”)

search for a word and print the entire line

inFile.each_line { |line|
for kw in line # keywords to search for
print line # let the lines print to console
outFile.write line # also print to file
end
}

close the files

inFile.close
outFile.close

visual clue script is done

puts “Finished processing file…”

THis overwrites your kw array with ‘line’

Try something like (untested)

 for word in kw
   if line.include?(word)
print line	  # let the lines print to console
outFile.write line	# also print to file
  end
 end
