Need Help??

Two points about OS:

To send a signal to a process group, you have to be a super user;
Most of OS's, if not all, does not let you capture SIGTERM for ordinary users. That's for a good reason, if some processes (intentionally or by mistake - bugs) decide to be alive forever, that will really be a nightmare.

This program doesn't work when run as root either.
I believe you're thinking of SIGKILL. SIGTERM is a perfectly normal signal. If I change the kill command to just send a normal signal to $kidpid, then the child process prints the TERM message, but not the grandchildren. Similarly, if you make the sleeps a little longer, you can send TERM signals by hand to individual grandchildren, and they print the message.
