Signal Processing in unix

I've read the man page of singal(3) but I still can't quite understand what is the difference between SIGINT, SIGALRM and SIGTERM.

Can someone tell me what is the behavioral difference among these 3 signals in kill command?

Thanks!

SIGINT = Stop now !
SIGALRM = Hey !
SIGTERM = Would you mind commit suicide please ...

That keeps things easy to remember.. great! :slight_smile:
