uuidd

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

       -F, --no-fork
              Do not daemonize using a double-fork.

       -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, --no-pid
              Do not create a pid file.

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

       -q, --quiet
              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-activation
              Do not create a socket but instead expect it to be  provided  by
              the calling process.  This implies --no-fork and --no-pid.  This
              option is intended to be used only with systemd(1).  It needs to
              be enabled with a configure option.

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

       -T, --timeout number
              Make uuidd exit after number seconds of inactivity.

       -t, --time
              Test uuidd by trying to connect to a running  uuidd  daemon  and
              uuidd -d -r -n 42 -s /tmp/uuidd.socket
              uuidd -d -k -s /tmp/uuidd.socket
