Subject: Directory searching againist a text file

I am in the middle of writing a quick program which will scan the
contents of a given file path recursively for a list of keywords stored
in a file. My code so far is below, but before moving ahead I have two
questions.

First: I am passing in a text file called "terms.txt" to search for each
keyword in the file I assume the best way to to do so is as follows:

terms.each do |term|
if line =~ term
  puts ""
end

My second question is: This program works well for searching text files
but what about word docs and spreadsheets? Do i need some Windows API in
there??


Many thanks


require 'find'

class ESearch

  #method which is passed file path from cmd line
  def scanFiles(path)
    terms  = "C:\Documents and Settings\user\Desktop\terms.txt"
    #process each file under the passed file path
    Find.find(path) do |curPath|
      next unless File.file?(curPath)
      #process the contens of each file line by line counting line
nmbers
      File.open(curPath) do |file|
        file.each do |line|
          #check if a line in the file matches term and output the path
and line number
          if line =~ terms
            puts "#{curPath}"
          end
        end
      end
    end
  end
end

#run of cmd line pass in file path, this will ask for a file path if one
is not passed
if __FILE__ == $0
  if ARGV.size != 1
    puts "Use: #{$0} [path]"
    exit
  end

  esearch = ESearch.new()
  esearch.scanFiles(ARGV[0])
end
