Kill all child processes on trap
hi

OS: Sun Solaris

I have a scenario that when someone presses ctrl-c while executing a shell script, it should not just exit. it should kill all the child processes started by the running shell script only.

I am executing many other scripts parallely which in turn fork off more processes.

I tried
Code:
ps -ef | grep <processname> | awk '{print $2}' | xargs kill -9

but it will kill not only the processes started by the running script but also the other processes.

please help me out.

Thank you.

kill

KILL(1) 						      General Commands Manual							   KILL(1)

NAME

       kill, broke - print commands to kill processes

SYNOPSIS

       kill name

       broke

DESCRIPTION

       Kill  prints  commands  that  will cause all processes called name and owned by the current user to be terminated.  Use the send command of
       81/2(1), or pipe the output of kill into rc(1) to execute the commands.

       Kill suggests sending a kill note to the process; the same message delivered to the process's ctl file (see proc(3)) is a surer,  if  heavy
       handed, kill, but is necessary if the offending process is ignoring notes.

       Broke  prints  commands	that  will  cause all processes in the Broken state and owned by the current user to go away.  When a process dies
       because of an error caught by the system, it may linger in the Broken state to allow examination with a debugger.  Executing  the  commands
       printed by broke lets the system reclaim the resources used by the broken processes.

SOURCE

       /rc/bin/kill
       /rc/bin/broke
