UUIDGEN(1) User Commands UUIDGEN(1)

NAME

uuidgen - command-line utility to generate UUID's

SYNOPSIS

uuidgen [-r | -t] [-o filename]

DESCRIPTION

The uuidgen command generates and prints a Universally Unique
IDentifier (UUID). By default uuidgen creates a new UUID based on high-
quality randomness from arc4random(3C) (DCE version 4). If the -t
option is provided then a time-based (DCE version 1) UUID will be
generated.

OPTIONS

-r Generate a UUID using uuid_generate_random() instead of
uuid_generate(). This derives the new UUID from random data.

-t Generate a UUID using uuid_generate_time() instead of
uuid_generate(). This uses the current time and either the
Ethernet address (if available) or system node ID.

-o Redirect output to filename instead of stdout.

EXIT STATUS

0 Successful completion.

>0 Failure.

INTERFACE STABILITY

Uncommitted.
