uuidgen(1)uuidgen(1)NAMEuuidgen - Generates a Universal Unique Identifier (UUID)
SYNOPSISuuidgen [argument] ...
Arguments
Allows you to supply an existing UUID that uuidgen then outputs in the
format you specify. This option is especially useful in combination
with the -s option for converting an existing UUID into a C structure.
You must specify the -c option at the end of the uuidgen command line;
all options that follow -c are ignored. Produces an Interface Defini‐
tion Language (IDL) file template and includes the generated UUID
string in the template. Redirects the generated UUID string to the
file you specify. Generates a UUID string as an initialized C struc‐
ture. Displays the version number of the UUID generator, but does not
generate a UUID. Displays information about the uuidgen command argu‐
ments. The arguments -h and -? can be used interchangeably. Displays
information about the uuidgen command arguments. The arguments -? and
-h can be used interchangeably. Generates a specified number of UUID
strings. Generates UUID using the hardware address of specified lan
card instance ,In case of multiple lan interfaces for a host.You can
use lanscan to get the card instance of the lancards.
DESCRIPTION
The uuidgen command creates a UUID string that you assign to an object
to uniquely identify it. One such use is in the UUID interface
attribute of an IDL interface definition. The format for representing
a UUID string consists of eight hexadecimal digits followed by a dash,
followed by three groups of four hexadecimal digits separated by
dashes, followed by a dash and twelve hexadecimal digits:
01234567-89ab-cdef-0123-456789abcdef
FILES
The locations of files have the following pathnames: Generator Genera‐

EXAMPLES
Generate a UUID string: $ uuidgen 23c67e00-71b6-11c9-9dfc-08002b0ecef1
Generate a partial template, containing a generated UUID string, to be
used to develop an interface definition: $ uuidgen-i [
uuid(828bf780-71b6-11c9-b5a8-08002b0ecef1), version (1.0) ] interface
INTERFACENAME {
} Convert a UUID string from the old-style format to the new format: $
uuidgen-t 34DC23469EAF.AB.A2.01.7C.5F.2C.ED.A3
34dc2346-9eaf-0000-aba2-017c5f2ceda3 Generate four UUID strings: $
uuidgen-n 4 612c0b00-71b8-11c9-973a-08002b0ecef1
612c0b01-71b8-11c9-973a-08002b0ecef1
612c0b02-71b8-11c9-973a-08002b0ecef1
612c0b03-71b8-11c9-973a-08002b0ecef1 Convert a UUID into a C structure:
$ uuidgen-s-c 1251ace6-93al-11cd-95ad-0800097086e4 = { /*
1251ace6-93al-11cd-95ad-0800097086e4 */ 0x1251ace6,
0x93al, 0x11cd, 0x95, 0xad
{0x08, 0x00, 0x09, 0x70, 0x86, 0xe4} }; To generate UUID
using the hardware address of lancard, whose instance number is 1 . $
uuidgen-l 1 5f393fde-a9db-11d1-9caf-080009306cc2
uuidgen(1)
