uuidd


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.
