Subject: Re: Error Exception if script doesn't run

That really helps clear things up..thanks.

I am almost there but have been struggling to get my e.message into my 
sendmail statement.

This code works perfectly but does not contain the value of e in my 
email:

rescue Exception => e
   #puts e.message ->prints out correctly
   #puts e.backtrace.first -> prints out correctly
      if e
        `echo "Subject:Error Message\n" | /usr/sbin/sendmail -f 
my_server\@server.com john.smith\@email.com`
      end
end

When I try to add the value of e into my email message, it won't send:

`echo "Subject:Error Message\n #{e.message}" | /usr/sbin/sendmail -f 
my_server\@server.com john.smith\@email.com`

I think it has something to do with the ` and " characters but I have 
tried every possible combination and I can't figure out why doesn't 
work?

thanks

jack
