lastwords(1m) USER COMMANDS lastwords(1m)
lastwords - print syscalls before exit. Uses DTrace.
This prints the last few system calls for processes matching the given
name, when they exit. This makes use of a ring buffer so that the impact
on the system is minimised.
Since this uses DTrace, only users with root privileges can run this
