NAME
kill.d - snoop process signals as they occur. Uses DTrace.
SYNOPSIS
kill.d
DESCRIPTION
kill.d is a simple DTrace program to print details of process signals as they are sent, such as the PID source and destination, signal number and result.
This program can be used to determine which process is sending signals to which other process.
Since this uses DTrace, only users with root privileges can run this command.
