.Sh NAME | ||
.Nm uuidgen | ||
.Nd command-line utility to generate UUID's | ||
.Sh SYNOPSIS | ||
.Nm uuidgen [-r | -t] [-o filename] | ||
.Sh DESCRIPTION | ||
The | ||
.Nm | ||
command generates and prints a Universally Unique | ||
IDentifier (UUID). By default | ||
.Nm | ||
creates a new UUID based on high-quality randomness from | ||
arc4random(3C) (DCE version 4). If the \fB-t\fR option is | ||
provided then a time-based (DCE version 1) UUID will be | ||
generated. | ||
.Sh OPTIONS | ||
.Bl -tag -width indent | ||
.It Fl r | ||
Generate a UUID using | ||
.Nm uuid_generate_random() | ||
instead of | ||
.Nm uuid_generate() . | ||
This derives the new UUID from random data. | ||
.It Fl t | ||
Generate a UUID using | ||
.Nm uuid_generate_time() | ||
instead of | ||
.Nm uuid_generate() . | ||
This uses the current time and either the | ||
Ethernet address (if available) or system node ID. | ||
.It Fl o | ||
Redirect output to | ||
.Ar filename | ||
instead of stdout. | ||
.El | ||
.Sh EXIT STATUS | ||
.Bl -tag -width Ds | ||
.It Dv 0 | ||
Successful completion. | ||
.It Dv >0 | ||
Failure. | ||
