NAME

       uuidgen - a universally unique identifier (UUID) generator for XPLC

SYNOPSIS

       uuidgen [ OPTION ] ...
       uuidcdef [ OPTION ] ...

DESCRIPTION

       uuidgen	generates  a  new universally unique identifier (UUID).  This UUID can be assumed to be unique to any other UUIDs generated on the
       local system, as well as those created on any other systems, at any time in the past or future.

       By default, uuidgen will try to generate a UUID with as much randomness as possible.  It  tries	to  pick  out  a  high-quality	randomness
       source.	If it cannot find one, it will fall back on using a time-based algorithm.

OPTIONS

       -c, --cdef
	      Print the UUID as an initializer for a C structure, compatible with the type used by XPLC.

	      This is the default mode for uuidcdef.

       -r, --random
	      Demand  that  the  random-based  algorithm be used to generate the UUID.	This will prefer a high-quality randomness source, but may
	      fall back on a low-entropy one.

       -t, --time
	      Demand that the time-based algorithm be used to generate the UUID.

       -u, --uuid
	      Print the UUID like: "26175a27-c35d-4615-8dfb-1509eab28ef8".  This is the printf(3) format: "%08x-%04x-%04x-%04x-%012x".

	      This is the default mode for uuidgen.

NAME

       uuidgen - command-line utility to create a new UUID value

SYNOPSIS

       uuidgen [-r|-t]

DESCRIPTION

       The uuidgen program creates (and prints) a new universally unique identifier (UUID) using the libuuid(3) library.  The new UUID can reason-
       ably 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 UUID's which uuidgen can generate: time-based UUID's and random-based UUID's.	By default uuidgen will generate a
       random-based UUID if a high-quality random number generator is present.	Otherwise, it will chose 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     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     Generate a time-based UUID.  This method creates a UUID based on the system clock plus the system's ethernet  hardware  address,	if
	      present.
