UIDGEN(1)                BSD General Commands Manual               UIDGEN(1)

NAME
     uuidgen -- command-line utility to generate a new UID value

SYNOPSIS
     uuidgen

DESCRIPTION
     The uuidgen command generates a Universally Unique Identifier (UID), a
     128-bit value guaranteed to be unique. A UID is made unique over both
     space and time by combining a value unique to the computer on which it
     was generated--usually the Ethernet hardware address--and a value repre-
     senting the number of 100-nanosecond intervals since October 15, 1582 at
     00:00:00.

RETURN VALUE
     The UID is returned to standard output as a hyphen-punctuated ASCI
     string of the form: 68753A44-4D6F-1226-9C60-0050E4C00067 (in printf(3)
     format "%08x-%04x-%04x-%04x-%012x").
