Generate a Unique ID (UUID/GUID)
Syntax uuidgen [-hdr] Key -hdr Emit CoreFoundation CFUUID-based source code for using the uuid in a header.
The UUID is printed to standard output as a hyphen-punctuated ASCII string of the form:
(in printf(3) format "%08X-%04X-%04X-%04X-%012X"),
unless the -hdr option is given, in which case a fragment of source code is output.
