NAME

uuidgen — command-line utility to generate UUID's

SYNOPSIS

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.
