Automated Script for Process killing
Hello all,

I'm in need of a Script which needs to wait for all the child process to end and then kill the main process.

I have a process called
Code:
mainpp

which runs for different instances like
Code:
evpn, nge, gmn etc

so when i query for
Code:
mainpp

process it looks like below.

Code:
bash-3.2$ ps -eaf | grep -i mainpp
   mainpp 14474 13672   0   mrt 08 ?          14:17 /opt/mainpp/bin/mon /opt/mainpp/etc/emtn-gsm.conf
   mainpp 14535 13672   0   mrt 08 ?          17:25 /opt/mainpp/bin/mon /opt/mainpp/etc/gmnjuniper.conf
   mainpp 14627 13672   0   mrt 08 ?           6:28 /opt/mainpp/bin/mon /opt/mainpp/etc/pwifi.conf
   mainpp 14636 13672   0   mrt 08 ?        1109:43 /opt/mainpp/bin/mon /opt/mainpp/etc/wwp.conf
   mainpp 14546 13672   0   mrt 08 ?          31:07 /opt/mainpp/bin/mon /opt/mainpp/etc/gmnwwp.conf
   mainpp 14440 13672   0   mrt 08 ?        1741:35 /opt/mainpp/bin/mon /opt/mainpp/etc/alcatel.conf
   mainpp 14447 13672   0   mrt 08 ?          13:18 /opt/mainpp/bin/mon /opt/mainpp/etc/asr9001.conf

the child process gets invoked for every 5 mins, and looks like below

Code:
bash-3.2$ ps -eaf | grep -i mainpp | grep -i rtr
   mainpp 17628 13672   0 11:10:08 ?           0:00 /opt/mainpp/bin/rtr poll.5 /opt/mainpp/etc/alcatel.conf

Code:
rtr

process gets ended on its own depends of work stack it has in its list, once the
Code:
rtr

is ended then i would like to kill
Code:
mainpp

i need a script which will wait for the
Code:
rtr

process to end and then kill the
Code:
mainpp
