uuidd

UUIDD is a command-line tool that stands for "Universally Unique Identifier (UUID) Daemon." It is primarily used to generate and manage UUIDs on a Linux system. UUIDs are 128-bit unique identifiers that can be used to uniquely identify objects, files, or even devices. The uuidd daemon helps prevent UUID collisions by maintaining a central pool of available UUIDs. This tool is commonly used in various contexts, such as distributed systems, file systems, and databases, where unique identifiers are crucial. uuidd typically runs as a daemon process in the background and communicates with applications through sockets. It provides a reliable and efficient way to generate and manage UUIDs on Linux systems, ensuring that uniqueness is maintained across various components and applications.
