Generate a UUID in Bash

The uuidgen command ships on most Unix systems; Linux also exposes a UUID via the kernel.

Bash example

Bash

uuidgen
# Linux box without uuidgen:
cat /proc/sys/kernel/random/uuid

Here's a fresh version 4 UUID generated right now — copy it, or call the API from any language.
