NAME

     uuidgen -- generate universally unique identifiers

SYNOPSIS

     uuidgen [-1s] [-n count] [-o filename]

DESCRIPTION

     The uuidgen utility by default generates a single universally unique identifier (UUID), also known as a globally unique identifier (GUID).
     By default, uuidgen generates a single UUID and outputs it in the standard string representation to stdout.  The following options can be
     used to change the behavior of uuidgen:

	   -1		  This option only has effect if multiple identifiers are to be generated and instructs uuidgen to not generate them in
			  batch, but one at a time.

	   -n count	  This option controls the number of identifiers generated.  By default, multiple identifiers are generated in batch.

	   -o filename	  Redirect output to filename instead of stdout.

	   -s		  Output UUIDs as initialized C structures, rather than in the standard string format.

     Batched generation yields a dense set of identifiers in such a way that there is no identifier that is larger than the smallest identifier in
     the set and smaller than the largest identifier in the set and that is not already in the set.

     When generating the identifiers one at a time, the identifiers will be close to each other, but operating system latency and processing time
     will be reflected in the distance between two successive identifiers.

DIAGNOSTICS

     The uuidgen utility exits 0 on success, and >0 if an error occurs.

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.
