.IX Header "DESCRIPTION"
\&\fB\s-1OSSP\s0 uuid\fR is a \s-1ISO\-C:1999\s0 application programming interface (\s-1API\s0) and
corresponding command line interface (\s-1CLI\s0) for the generation of \s-1DCE\s0
1.1, \s-1ISO/IEC\s0 11578:1996 and \s-1IETF\s0 \s-1RFC\-4122\s0 compliant \fIUniversally Unique
Identifier\fR (\s-1UUID\s0). It supports \s-1DCE\s0 1.1 variant UUIDs of version 1 (time
and node based), version 3 (name based, \s-1MD5\s0), version 4 (random number
based) and version 5 (name based, \s-1SHA\-1\s0). Additional \s-1API\s0 bindings are
provided for the languages \s-1ISO\-\*(C+:1998\s0, Perl:5 and \s-1PHP:4/5\s0. Optional
backward compatibility exists for the ISO-C \s-1DCE\-1\s0.1 and Perl Data::UUID
APIs.
.PP
UUIDs are 128 bit numbers which are intended to have a high likelihood
of uniqueness over space and time and are computationally difficult
to guess. They are globally unique identifiers which can be locally
generated without contacting a global registration authority. UUIDs
are intended as unique identifiers for both mass tagging objects
with an extremely short lifetime and to reliably identifying very
persistent objects across a network.
.PP
This is the command line interface (\s-1CLI\s0) of \fB\s-1OSSP\s0 uuid\fR. For a
detailed description of UUIDs see the documentation of the application
programming interface (\s-1API\s0) in \fIuuid\fR\|(3).
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-v\fR \fIversion\fR" 3
.IX Item "-v version"
Sets the version of the generated \s-1DCE\s0 1.1 variant \s-1UUID\s0. Supported
are \fIversion\fR "\f(CW1\fR\*(L", \*(R"\f(CW3\fR\*(L", \*(R"\f(CW4\fR\*(L" and \*(R"\f(CW5\fR\*(L". The default is \*(R"\f(CW1\fR".
.Sp
For version 3 and version 5 UUIDs the additional command line arguments
\&\fInamespace\fR and \fIname\fR have to be given. The \fInamespace\fR is either
a \s-1UUID\s0 in string representation or an identifier for internally
pre-defined namespace UUIDs (currently known are "\f(CW\*(C`ns:DNS\*(C'\fR\*(L",
\&\*(R"\f(CW\*(C`ns:URL\*(C'\fR\*(L", \*(R"\f(CW\*(C`ns:OID\*(C'\fR\*(L", and \*(R"\f(CW\*(C`ns:X500\*(C'\fR"). The \fIname\fR is a string of
arbitrary length.
.IP "\fB\-m\fR" 3
.IX Item "-m"
Forces the use of a random multi-cast \s-1MAC\s0 address when generating
version 1 UUIDs. By default the real physical \s-1MAC\s0 address of the system
is used.
.IP "\fB\-n\fR \fIcount\fR" 3
.IX Item "-n count"
Generate \fIcount\fR UUIDs instead of just a single one (the default).
.IP "\fB\-1\fR" 3
.IX Item "-1"
If option \fB\-n\fR is used with a \fIcount\fR greater than \f(CW1\fR, then this
option can enforce the reset the \s-1UUID\s0 context for each generated \s-1UUID\s0.
This makes no difference for \fIversion\fR \f(CW3\fR, \f(CW4\fR and \f(CW5\fR UUIDs. But
version \f(CW1\fR UUIDs are based on the previously generated \s-1UUID\s0 which is
remembered in the \s-1UUID\s0 context of the \s-1API\s0. Option \fB\-1\fR deletes the
remembered \s-1UUID\s0 on each iteration.
.IP "\fB\-F\fR \fIformat\fR" 3
.IX Item "-F format"
Representation format for importing or exporting an \s-1UUID\s0. The
following (case insensitive) format identifiers are currently recognized:
.RS 3
.ie n .IP "\*(C`BIN\*(C' (binary representation)" 4
.el .IP "\f(CW\*(C`BIN\*(C'\fR (binary representation)" 4
.IX Item "BIN (binary representation)"
This is the raw 128 bit network byte order binary representation of a
\&\s-1UUID\s0. Example is the octet stream \f(CW\*(C`0xF8 0x1D 0x4F 0xAE 0x7D 0xEC 0x11
0xD0 0xA7 0x65 0x00 0xA0 0xC9 0x1E 0x6B 0xF6\*(C'\fR.
.ie n .IP "\*(C`STR\*(C' (string representation)" 4
.el .IP "\f(CW\*(C`STR\*(C'\fR (string representation)" 4
.IX Item "STR (string representation)"
This is the 36 character hexadecimal \s-1ASCII\s0 string representation of a
\&\s-1UUID\s0. Example is the string "\f(CW\*(C`f81d4fae\-7dec\-11d0\-a765\-00a0c91e6bf6\*(C'\fR".
.ie n .IP "\*(C`SIV\*(C' (single integer value representation)" 4
.el .IP "\f(CW\*(C`SIV\*(C'\fR (single integer value representation)" 4
.IX Item "SIV (single integer value representation)"
This is the maximum 39 character long single integer
value representation of a \s-1UUID\s0. Example is the string
"\f(CW329800735698586629295641978511506172918\fR".
.RE

.RE
.IP "\fB\-o\fR \fIfilename\fR" 3
.IX Item "-o filename"
Write output to \fIfilename\fR instead of to \fIstdout\fR.
.IP "\fB\-d\fR" 3
.IX Item "-d"
Decode a given \s-1UUID\s0 (given as a command line argument or if the command
line argument is "\f(CW\*(C`\-\*(C'\fR" the \s-1UUID\s0 is read from \fIstdin\fR) and dump textual
information about the \s-1UUID\s0.
