Subject: Help:  very simple script problem

Hi,

After reading up on Ruby I thought it sounded good and
decided to learn it so I can manipulate my files on my
linux server such as log, csv, conf etc.  Anyway, i'm
a beginner when it comes to programming, so bear with
me.

I use the Asterisk PBX and came across this script
here which reads a csv file and puts each record into
an html table:
http://rubyforge.org/snippet/detail.php?type=snippet&id=76


Anyway, I thought I would then apply this basic
concept to a log file, but I cannot get it to display
through a web browser.   Here is my script:


===========
#!/usr/bin/ruby

My_Title = "Testing Log Read"
Log_File = "/var/log/apache2/error.log"

require 'cgi'

cgi = CGI.new
printf cgi.header("Content-type" => "text/html\n\n")


printf "<html>\n<head>\n"
printf "<title>#{My_Title}</title>\n"
printf "</head>\n<body bgcolor=\"#efefef\">\n"
printf "<table width=\"80%\">\n<tr><td>Call
records</td></tr>\n"
if File.exists? Log_File
    lines = File.open(Log_File).readlines
    lines.each_with_index do |line, index|
      printf "     <tr%s>\n      <td>%d</td>",
    index % 2 == 0 ? ' bgcolor="#dddddd"' : '
bgcolor="#cccccc"', index + 1 
      entries = line.chop.split(/\n/)
      entries.each_with_index do |field, index|
        printf "<td>%s</td>", entries
      end
     printf "\n</tr>\n"
    end
else
    printf "No File Found\n"
end
printf "</body>\n</html>"
===========


If I comment out all the printf commands related to
web and cgi, and run it through the shell, it seems to
be taking each line and putting it into <tr><td>
brackets, but I can't get it to display through a
browser, it stops at the third printf command.


I have tried heaps of different things, but feel like
i'm running around in circles now.

Any advise with this one?


Cheers.
Tristan
