NAME

       uuidd - UUID generation daemon

SYNOPSIS

       uuidd [options]

DESCRIPTION

       The  uuidd  daemon  is used by the UUID library to generate universally unique identifiers
       (UUIDs), especially time-based UUIDs, in a secure and guaranteed-unique fashion,  even  in
       the face of large numbers of threads running on different CPUs trying to grab UUIDs.

OPTIONS

       -d     Run uuidd in debugging mode.  This prevents uuidd from running as a daemon.

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

       -k, --kill
              If currently a uuidd daemon is running, kill it.

       -n, --uuids number
              When  issuing  a test request to a running uuidd, request a bulk response of number
              UUIDs.

       -p, --pid path
              Specify the pathname where the pid file should be written.   By  default,  the  pid
              file is written to /var/run/uuidd/uuidd.pid.

       -q     Suppress some failure messages.

       -r, --random
              Test  uuidd by trying to connect to a running uuidd daemon and request it to return
              a random-based UUID.

       -s, --socket path
              Specify the pathname used for the unix-domain socket used by  uuidd.   By  default,
              the  pathname  used  is  /var/run/uuidd/request.   This  is primarily for debugging
              purposes, since the pathname is hard-coded in the libuuid library.

       -T, --timeout timeout
              Specify a timeout for uuidd.  If specified, then  uuidd  will  exit  after  timeout
              seconds of inactivity.

       -t, --time
              Test  uuidd by trying to connect to a running uuidd daemon and request it to return
              a time-based UUID.

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

EXAMPLE

       Start up a daemon, print 42 random keys, and then stop the daemon.

              uuidd -p /tmp/uuidd.pid -s /tmp/uuidd.socket
              uuidd -d -r -n 42 -s /tmp/uuidd.socket
              uuidd -d -k -s /tmp/uuidd.socket
