All,

I have to get the process id for a specified ruby program.  
(e.x) $0 returns the current process name Process.pid returns the  
current  
process id.So how can i get the specified program’s pid.

So you want something like “lookup some other ruby program’s PID”?  
-r

Presumably, in which case you want sys-proctable.

gem install sys-proctable
