Make sure that you use exec to execute your ruby script. The pid of  
the bash script will then be the pid of the ruby program. Also make  
sure _not_ to use '&' at the end when starting the ruby program as  
this will fork and start a new process so the pid is wrong, which  
seems to be   the case with your script. Maybe we can have a look at  
your bash script if this does not work out?
