Subject: [ruby-talk:20547] CGI in Ruby with Apache and Exec

Hello, 

I am a newbie to the Ruby programming language. I have have found it
to be very absolutly brilliant for everything I wish to do with two
big exceptions.

1: I can't seem to run my Ruby CGI scripts through my apache web
server (under windows). My Perl scripts run fine.

I am having great trouble with this CGI in Ruby business. I have the
pragmatic programmers book on Ruby and well phenomenal for other
aspects of ruby programming (it has been a good friend to me during
the past few weeks).

As regards CGI in ruby......I still can't make the books basic
examples work.

My task: I am trying to pick up parameters from a form written in HTML
and then pass out the processed data in HTML. I have had a good old go
but I keep getting '500 Internal server error'. Does anyone have have
links  to a good tutorial for absolute monkeys like me!

2: I can't seem to manage to get  'exec' up and running. Here is my
code where am I going wrong.

Function: The parent passes 3 variables to multiple child processes.
Each child is given the same regexpression but a differrent file to
parse and a different file to write the matches into.

The parent calls process.wait as many times as there are children.
(Next part not shown) The parent then scoops up the results in an
array for output in CGI format.

bert=["c:\\westd\\westdb1.txt","c:\\westd\\westdb2.txt","c:\\westd\\westdb4.txt","c:\\westd\\westdb5.txt","c:\\westd\\westdb6.txt","c:\\westd\\westdb7.txt"]
ernie=["c:\\westd\\resregmatch1.txt","c:\\westd\\resregmatch2.txt","c:\\westd\\resregmatch3.txt","c:\\westd\\resregmatch4.txt","c:\\westd\\resregmatch5.txt","c:\\westd\\resregmatch6.txt,""c:\\westd\\resregmatch7.txt"]
re_str="((at[ct])|(act))"


	(0...bert.length).each  {|i| 
         exec ("c:\\westd\\cherub3.rb","#{re_str}", "#{bert[i]}",
"#{ernie[i]}")
	 if fork==nil}

        (0...bert.length).each{|i| i=i-1	 
         Process.wait
	}

I would appreciate any guidence that can be offerred.

Regard.
