uuidgen: Generate a UUID string.
$ uuidgen
try on your machine
The command "uuidgen" is used to generate a universally unique identifier (UUID). UUID is a 128-bit value that is unique across all devices and all time. It is often used to uniquely identify resources in computer systems, such as files or database records.
When you execute the "uuidgen" command, it generates a new random UUID and displays it as output. The generated UUID is a combination of alphanumeric characters separated by hyphens, following a specific format defined by the UUID standards.
The generated UUID can be used for various purposes, such as creating unique identifiers for objects or entities in programming, generating unique filenames, ensuring uniqueness in distributed systems, or as a random identifier in general.
