uuidd
UUID generation daemon service
TLDR
Generate random UUID
$ uuidd -r
Generate bulk random UUIDs$ uuidd -r -n [number_of_uuids]
Generate time-based UUID$ uuidd -t
SYNOPSIS
uuidd [OPTIONS]
DESCRIPTION
uuidd is a daemon for generating UUIDs (Universally Unique Identifiers). It provides a central service for generating UUIDs to ensure uniqueness across multiple processes and prevent clock issues with time-based UUIDs.
The daemon can generate both random (version 4) and time-based (version 1) UUIDs.
PARAMETERS
-r, --random
Generate random-based UUID-t, --time
Generate time-based UUID-n, --uuids N
Generate N UUIDs in bulk-d, --daemon
Run as a daemon-p, --pid FILE
Write PID to file
CAVEATS
Time-based UUIDs expose MAC address. Running as daemon requires appropriate permissions. Part of util-linux package.
