   4      uuidgen  command-line utility to generate UUID's
   5 
   6 SYNOPSIS
   7      uuidgen [-r | -t] [-o filename]
   8 
   9 DESCRIPTION
  10      The uuidgen command generates and prints a Universally Unique IDentifier
  11      (UUID). By default uuidgen creates a new UUID based on high-quality
  12      randomness from arc4random(3C) (DCE version 4). If the -t option is
  13      provided then a time-based (DCE version 1) UUID will be generated.
  14 
  15 OPTIONS
  16      -r      Generate a UUID using uuid_generate_random() instead of
  17              uuid_generate().  This derives the new UUID from random data.
  18 
  19      -t      Generate a UUID using uuid_generate_time() instead of
  20              uuid_generate().  This uses the current time and either the
  21              Ethernet address (if available) or system node ID.
  22 
  23      -o      Redirect output to filename instead of stdout.
  24 
  25 EXIT STATUS
  26      0       Successful completion.
