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..."
