UUIDD 8 "@E2FSPROGS_MONTH@ @E2FSPROGS_YEAR@" "E2fsprogs version @E2FSPROGS_VERSION@"
NAME
uuidd - UUID generation daemon
SYNOPSIS
uuidd [ -d ] [ -p pidfile ] [ -s socketpath ] [ -T timeout ] uuidd [ -r | -t ] [ -n number ] [ -s socketpath ] uuidd -k
DESCRIPTION
The uuidd daemon is used by the UUID library to generate universally unique identifiers (UUIDs), especially time-based UUID's in a secure and guaranteed-unique fashion, even in the face of large numbers of threads trying to grab UUID's running on different CPU's.
OPTIONS

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

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

-n " number" When issuing a test request to a running uuidd, request a bulk response of number UUID's.

-p " pidfile" Specify the pathname where the pid file should be written. By default, the pid file is written to /var/lib/libuuid/uuidd.pid.

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

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

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

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