10 uuidgen \- command\-line utility to create a new UUID value
21 program creates (and prints)
22 a new universally unique identifier (UUID) using the
24 library. The new UUID can reasonably be considered unique among
25 all UUIDs created on the local system,
26 and among UUIDs created on other systems in the past
29 There are two types of UUID's which
31 can generate: time-based UUID's and random-based UUID's. By
34 will generate a random-based UUID if a high-quality random number
35 generator is present. Otherwise, it will chose a time-based UUID. It
36 is possible to force the generation of one of these two
37 UUID types by using the
45 Generate a random-based UUID. This method creates a UUID consisting mostly
46 of random bits. It requires that the operating system have a high
47 quality random number generator, such as
51 Generate a time-based UUID. This method creates a UUID based on the system
52 clock plus the system's ethernet hardware address, if present.
