Subject: Re: Open file, get first line, delete first line close file


I've set it up with a rake task and a cron job, that re-runs every 5hrs 
(my timeout window)

i this is the code that i've already uploaded, and is currently 
running...

namespace :chinese do

desc "adds all chinese files to database"
task :create => :environment do

active_dictionary = 
File.readlines("public/languages/chinese/practice.txt")
      count = 0
      for @element in active_dictionary
             count += 1
             process_chinese
               open('public/languages/chinese/practice.txt', 'w') do 
|file|
                   file.puts 
active_dictionary[count,active_dictionary.size]
               end

       end

end

end

where process_chinese contains all my proprietary code, i played around 
with only writing to the file every time i've processed ten entries, but 
it only cut my process time down by a trivial amount of time, so i just 
let it write over the file after every line. As we've seen here, there 
are quite a few ways this can be accomplished, this ended up 
working...and didn't kill my processor (the writes to the DB are 
infinitely more expensive than opening and writing to this file).

Thanks for the help!!
Richard
