Ok , I am planning to go with system command , will send the command to background and also redirect the the output to log like shown below.

This way , I am able to send it to background and it does seems to be running. I am planning to use ps -ef | grep myoutput.log to grep the pid and then search for the pid at regular interval to trace its status. Can someone out there let me know if this sounds logical or possibly suggest me a better way please.
