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 command.

See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
bose descriptions explaining the output.
lastwords will sample until a command with that name exits.
