The optional argument can be used to set a value for the max_clock_offset. This gurantees, that a clock value of a UUID will always be within the range of the max_clock_offset. ++ +The option '-C' or '--cont-clock' enables the feature with a default max_clock_offset of 2 hours. ++ +The option '-C[hd]' or '--cont-clock=[hd]' enables the feature with a max_clock_offset of NUM seconds. In case of an appended h or d, the NUM value is read in hours or days. The minimum value is 60 seconds, the maximum value is 365 days. + +*-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 _{runstatedir}/uuidd/uuidd.pid_. +// TRANSLATORS: Don't translate _{runstatedir}_. + +*-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 _{runstatedir}/uuidd/request_. This option is primarily for debugging purposes, since the pathname is hard-coded in the *libuuid* library. +// TRANSLATORS: Don't translate _{runstatedir}_. + +*-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 request it to return a time-based UUID. + +include::man-common/help-version.adoc[] + +== 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 +.... + +== AUTHOR + +The *uuidd* daemon was written by mailto:tytso@mit.edu[Theodore Ts'o]. + +== SEE ALSO + +*uuid*(3), +*uuidgen*(1) + +include::man-common/bugreports.adoc[] + +include::man-common/footer.adoc[] + +ifdef::translation[] +include::man-common/translation.adoc[] +endif::[] -- cgit v1.2.3
