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
       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 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.
