.Dt UUIDGEN 1
|
||||
.Os
|
||||
.Sh NAME
|
||||
.Nm uuidgen
|
||||
.Nd generate universally unique identifiers
|
||||
.Sh SYNOPSIS
|
||||
.Nm
|
||||
.Op Fl 1s
|
||||
.Op Fl n Ar count
|
||||
.Op Fl o Ar filename
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
utility by default generates a single universally unique identifier (UUID),
|
||||
also known as a globally unique identifier (GUID).
|
||||
By default,
|
||||
.Nm
|
||||
generates a single UUID and outputs it in the standard string representation
|
||||
to stdout.
|
||||
The following options can be used to change the behavior of
|
||||
.Nm :
|
||||
.Bl -tag -offset indent -width XoXfilenameXX
|
||||
.It Fl 1
|
||||
This option only has effect if multiple identifiers are to be generated and
|
||||
instructs
|
||||
.Nm
|
||||
to not generate them in batch, but one at a time.
|
||||
.It Fl n Ar count
|
||||
This option controls the number of identifiers generated.
|
||||
By default, multiple identifiers are generated in batch.
|
||||
.It Fl o Ar filename
|
||||
Redirect output to
|
||||
.Ar filename
|
||||
instead of stdout.
|
||||
.It Fl s
|
||||
Output UUIDs as initialized C structures, rather than in the standard
|
||||
string format.
|
||||
.El
|
||||
.Pp
|
||||
Batched generation yields a dense set of identifiers in such a way that there
|
||||
is no identifier that is larger than the smallest identifier in the set and
|
||||
smaller than the largest identifier in the set and that is not already in the
|
||||
set.
|
||||
.Pp
|
||||
When generating the identifiers one at a time, the identifiers will be close
|
||||
to each other, but operating system latency and processing time will be
|
||||
reflected in the distance between two successive identifiers.
