You know that the whole point of the exec command is that it replaces the current process with what you tell it to run? You may be more interested in ``, system or things like IO.popen

Thanks Fred, As far as i know system is for windows, and Currently my application is deployed on linux.

That's not true

Can you tell me more about IO.popen ?

Got the solution, exec starts a new process so don't use it..

just use the shell command in ruby like this

`sh /home/abc.sh`

in the controller..

It runs fine

Thanks Every body
