Thanks, Park. I'll give this code a try.

I'm a newbie, but its clear I need to get a more advanced Ruby guide before I can do this level of coding (even though I'm sure its elementary) on my own.

Question: I've seen the "for line in file" in program samples like the one below. What's there a reason why this line-stepping technique would not have worked in my application?


    # Count the words in a file     #  1
                                    #  2
    filename = ARGV.shift           #  3
    words = 0                       #  4
    file = open(filename)           #  5
    for line in file                #  6
      words += line.split.length    #  7
    end                             #  8
    file.close                      #  9
                                    # 10
    puts "Word Count: #{words}"     # 11

I appreciate your help!

-Kurt

I think you want this code, don't you?

content = File.new("FileA").read
IO.foreach("FileB") { |x|
  field = x.chop.split(':')
  content2 = content
  # modify content2 here
  File.new(field[0],"w+").write(content2)
}
