Subject: Re: Calling Shell Scripts from Ruby ?

Hi Edwin,

Thanks for your reply.  When you say output = `Unix command`, i did not 
get about how exactly to use it, is it possible to give a simple sample 
examples if you have with you which calls a script ??

Oh..so u mean from shell script we can't get the return values to ruby. 
My requirement is that from "Rails" through the web i will call some 
shell script and  finally the script should return me a "String" value. 
is that not possible from ruby?


Thank You
Dinesh
