daemonise an executable namely "process2" with sleep interval of 30 seconds and in 5 parallel instances . Also pass parameters stored in daemon.cfg file
./daemoniserGen.sh -p process2 -a START -s 30 -c daemon.cfg -n 5
Stopping above daemon of process2
./daemoniserGen.sh -p process2 -a STOP -c daemon.cfg
