PROGRAM:

NAME


uuidgen - create a new UUID value

SYNOPSIS


uuidgen [options]

DESCRIPTION


The uuidgen program creates (and prints) a new universally unique identifier (UUID) using
the libuuid(3) library. The new UUID can reasonably be considered unique among all UUIDs
created on the local system, and among UUIDs created on other systems in the past and in
the future.

There are two types of UUIDs which uuidgen can generate: time-based UUIDs and random-based
UUIDs. By default uuidgen will generate a random-based UUID if a high-quality random
number generator is present. Otherwise, it will choose a time-based UUID. It is possible
to force the generation of one of these two UUID types by using the -r or -t options.

OPTIONS


-r, --random
Generate a random-based UUID. This method creates a UUID consisting mostly of
random bits. It requires that the operating system have a high quality random
number generator, such as /dev/random.

-t, --time
Generate a time-based UUID. This method creates a UUID based on the system clock
plus the system's ethernet hardware address, if present.

-h, --help
Display help text and exit.

-V, --version
Display version information and exit.
