Hello,
The file “/proc/sys/kernel/random/uuid” provides a bit of useful data.
The formal definition of the string representation for universally unique
identifiers requires the use of four dashes for the concatenation of fields.
https://tools.ietf.org/html/rfc4122#page-4
https://stackoverflow.com/questions/24481801/is-uuid-without-dashes-hyphens-valid#answer-24484051
Now I am looking again for possibilities to generate reasonably unique
identifiers also without these dashes.
Can any data processing benefit from the avoidance of such extra characters?
Regards,
Markus
