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
