uuidgen
—
command-line utility to generate UUID's
uuidgen [-r | -t] [-o filename] |

command generates and prints a
Universally Unique IDentifier (UUID). By default

creates a new UUID based on high-quality
randomness from arc4random(3C) (DCE version 4). If the -t option is
provided then a time-based (DCE version 1) UUID will be generated.

instead
of uuid_generate()
. This uses the current time and
either the Ethernet address (if available) or system node ID.-o
uuid_generate(3uuid), uuid_generate_random(3uuid), uuid_generate_time(3uuid)
