1N/AThe following is a demonstration of the fddist command,
1N/AHere fddist is run for a few seconds on an idle workstation,
1N/A Tracing reads and writes... Hit Ctrl-C to end.

1N/AThe above displays the usage pattern for process file descriptors.
1N/AWe can see the Xorg process (PID 1532) has made 57 reads or writes to
1N/Ait's file descriptor 23.
1N/AThe pfiles(1) command can be used to help determine what file
