Shell Programming and Scripting

Hi all,

I've been pulling my hair out with this problem for 3 days now without success any help would be massively appreciated.

Basically the script is used to shutdown a rails server so a new IP address can be assigned, the shutdown part is taken care of in function_one using the "pkill master" command. Once the server has been shutdown function_two is supposed to run and restart the server.

The problem is the when "pkill master" is run and the processes are killed the script is broken by the terminated message and function two never gets called. I understand that the terminated message is not coming from STDOUT or STDERR and that it is being generated by the shell's job control mechanism so I cant redirect to /dev/null or use 2>/dev/null to redirect the message.

I'm at my wits end I can not find a way to "pkill master" or "killall -q -r master" without generating the terminated message. Thanks in advance.

Code:

#!/bin/bash

function_one(){
if pgrep ruby > /dev/null | pgrep master
  then
      pkill master
      sleep 5
      function_two  
     
  else
       function_two  
    fi
}

function_two(){
    Do Stuff
}
function_one

Execution should not affect with the messages.
What are the Messages?

Sorry I should have included it
