> Generate and decode Universally Unique Identifiers (UUID).

|
|
|
- Generate a UUIDv1 (based on time and system's hardware address, if present):
|
|
|
|
`uuid`
|
|
|
|
- Generate a UUIDv4 (based on random data):
|
|
|
|
`uuid -v {{4}}`
|
|
|
|
- Generate multiple UUIDv4 identifiers at once:
|
|
|
|
`uuid -v {{4}} -n {{number_of_uuids}}`
|
|
|
|
- Generate a UUIDv4 and specify the output format:
|
|
|
|
`uuid -v {{4}} -F {{BIN|STR|SIV}}`
|
|
|
|
- Generate a UUIDv4 and write the output to a file:
|
|
|
|
`uuid -v {{4}} -o {{path/to/file}}`
|
|
|
|
- Generate a UUIDv5 (based on the supplied object name) with a specified namespace prefix:
|
|
|
|
`uuid -v {{5}} ns:{{DNS|URL|OID|X500}} {{object_name}}`
|
|
|
|
- Decode a given UUID:
|
|
|
|
`uuid -d {{uuid}}`
