How to propagate a signal through a collection of scripts?

Question

I have an collection of scripts which are controlled by a main one. I want to trap the signal ctrl+c in the main script and propagate it to the others.

Have you tried to : 1) Setup your traps in every script (master / childs) where you need them 2) Send to the master a kill with it's PID negated, to kill the whole process group, I mean :

kill -15 -$PID

man kill | grep -C1 Negative
