uuidgen(1)


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.
