how to force bash to deliver a signal to another process?

view story

http://stackoverflow.com – I have two processes. I am spawning the first process from the console(bash). And the first process is intern spawning the second process. The second process is reading from a file till it gets a SIGINT or SIGTERM signal from the user. But when I am pressing ctrl+c, bash program is delivering the signal to the first process, so it's getting killed and my application goes down, because I did not handle it there. so my question is how can I force bash program to deliver the signal to the second process ?? Thanks. (HowTos)
