I have a script in ruby that build a software for me once per day and  
when the code is wrong and a error, I don’t if the error has ocurred and  
I don’t know what happened.

I wanna know how I can saw the error, I want that this script tell me  
what happenend by email.

Thanks,

Ivan

Search for the docs on Net::SMTP in the ruby standard library.

How are you running it daily? If running from cron, then cron should  
capture  
your script’s output and mail it to the cron user’s uid.

Otherwise you could do something like  
IO.popen(“sendmail removed\_email\_address@domain.invalid”,“w”) do |io|  
io \<\< EOM  
From: system@yourhost  
To: removed\_email\_address@domain.invalid

Something nasty has happened!  
EOM  
end

YMMV (you didn’t say if this was Windows or Linux/Unix or something  
else)
