Generating identifiers similar to UUIDs but without dashes

[Markus Elfring]

Hello,

The file â/proc/sys/kernel/random/uuidâ 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.

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
