This prevents uuidd from running as a daemon. +.TP +.BR \-F , " \-\-no-fork" +Do not daemonize using a double-fork. +.TP +.BR \-k , " \-\-kill" +If currently a uuidd daemon is running, kill it. +.TP +.BR \-n , " \-\-uuids " \fInumber\fR +When issuing a test request to a running uuidd, request a bulk response +of +.I number +UUIDs. +.TP +.BR \-P , " \-\-no-pid" +Do not create a pid file. +.TP +.BR \-p , " \-\-pid " \fIpath\fR +Specify the pathname where the pid file should be written. By default, +the pid file is written to @runstatedir@/uuidd/uuidd.pid. +.TP +.BR \-q , " \-\-quiet" +Suppress some failure messages. +.TP +.BR \-r , " \-\-random" +Test uuidd by trying to connect to a running uuidd daemon and +request it to return a random-based UUID. +.TP +.BR \-S , " \-\-socket-activation" +Do not create a socket but instead expect it to be provided by the calling +process. This implies \fB\-\-no-fork\fR and \fB\-\-no-pid\fR. This option is +intended to be used only with \fBsystemd\fR(1). It needs to be enabled with +a configure option. +.TP +.BR \-s , " \-\-socket " \fIpath\fR +Make uuidd use this pathname for the unix-domain socket. By default, the +pathname used is @runstatedir@/uuidd/request. This option is primarily +for debugging purposes, since the pathname is hard-coded in the libuuid +library. +.TP +.BR \-T , " \-\-timeout " \fInumber\fR +Make uuidd exit after \fInumber\fR seconds of inactivity. +.TP +.BR \-t , " \-\-time" +Test uuidd by trying to connect to a running uuidd daemon and +request it to return a time-based UUID. +.TP +.BR \-V , " \-\-version" +Output version information and exit. +.TP +.BR \-h , " \-\-help" +Display help screen and exit. +.SH EXAMPLE +Start up a daemon, print 42 random keys, and then stop the daemon: +.PP +.RS +.nf +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 +.fi +.RE +.SH AUTHOR +The +.B uuidd +daemon was written by Theodore Ts'o <tytso@mit.edu>. +.SH "SEE ALSO" +.BR uuid (3), +.BR uuidgen (1) +.SH AVAILABILITY +The uuidd daemon is part of the util-linux package and is available from the +.UR https://\:www.kernel.org\:/pub\:/linux\:/utils\:/util-linux/ +Linux Kernel Archive +.UE . |
