Subject: Read and modify logs

I'm trying to read the entries in a logfile so I can enter its contents
in a database, the lines are results I want to record, but in order to
be sure that I don't have duplicates I'd like to be able to remove
entries that I have read.  Is there an easy way to do this in Ruby so I
can remove read lines from a file that is open once they've been
captured?

I'm not as worried about the conn_to_db.print line, that is something I
have working ok, so if it looks funny please ignore it.

What I have so far, and its untested as of yet as I am trying to get the
form right, until I am sure its working .

Example:
while running
  sleep 10
  # read file into an array
  f = file.open("mylogfile.log")
  saved = File.open("archive.log", "a")
  results = f.readlines
  # Is there a way to remove everything that's been read here?
  f.close
  results.each_line do |sending|
    conn_to_db.print("data #{sending}")
    # Make sure we keep a backup
    saved.puts("#{sending}")    s.flush
  end
  # Close the archive file
  saved.close
end

Thanks for any help!
