NAME
uuidgen - create a new UUID value SYNOPSIS
uuidgen [options] DESCRIPTION
The uuidgen program creates (and prints) a new universally unique identifier (UUID) using the libuuid(3) library. The new UUID can reason- ably be considered unique among all UUIDs created on the local system, and among UUIDs created on other systems in the past and in the future. There are two types of UUIDs which uuidgen can generate: time-based UUIDs and random-based UUIDs. By default uuidgen will generate a ran- dom-based UUID if a high-quality random number generator is present. Otherwise, it will choose a time-based UUID. It is possible to force the generation of one of these two UUID types by using the -r or -t options. OPTIONS
-r, --random Generate a random-based UUID. This method creates a UUID consisting mostly of random bits. It requires that the operating system have a high quality random number generator, such as /dev/random. -t, --time Generate a time-based UUID. This method creates a UUID based on the system clock plus the system's ethernet hardware address, if present. -h, --help Display help text and exit. -V, --version Display version information and exit.
