Request bulk
uuidd -r -n [number_of_uuids]
Request
uuidd -t
Kill
uuidd -k
Run
uuidd -d -T [seconds]
说明
uuidd is a daemon used by the UUID library to generate universally unique identifiers (UUIDs), especially time-based UUIDs, in a secure and guaranteed-unique fashion even when many threads on different CPUs request UUIDs simultaneously. The daemon can generate both random (version 4) and time-based (version 1) UUIDs. Part of the util-linux package.
