uuidgen

UUIDgen is a command line tool that generates unique identifiers known as Universally Unique Identifiers (UUIDs). UUIDs are 128-bit values, typically represented in hexadecimal format and are used to uniquely identify entities in the computing world. This tool is commonly found in Unix-like operating systems, including Linux and macOS. The generated UUIDs are based on a combination of the machine's network MAC address, the current timestamp, and a random value. UUIDgen uses a standard algorithm to ensure uniqueness across different machines and time periods. The UUIDs produced by this tool have a specific format that includes a combination of alphanumeric characters and hyphens to enhance readability. UUIDgen is often utilized in diverse scenarios, such as database records, distributed systems, messaging systems, and file systems, to provide a reliable way to generate unique identifiers.
