1/8/2024 0 Comments A uuid generatorNext time you’re in need of a UUID, save yourself the search for “online UUID generator” and use your system’s uuidgen command. Combined with some light shell scripting on the command-line interface, you’re able to generate useful data, without needing to load up your favorite programming language’s package repository. Their uniqueness makes them quite powerful. Universally unique identifiers are more robust than a random number. Their uniqueness does not depend on a central registration. When generated according to the standard methods, UUIDs are, for practical purposes, unique. The term globally unique identifier is also used. This time you’ll see output like can use the same approach to save any of the other examples in this tutorial to files. Universally Unique Identifier: A universally unique identifier is a 128-bit label used for information in computer systems. You’ll see output similar to the following, although your UUID will be aren’t real email addresses that you can validate, but you can tweak the output one more time, and swap the second uuidgen for a disposable email address domain, like ( ], you will not only have a list of realistic-looking data, but it will be a list email addresses you could actually use or monitor in tests. Out of the box, uuidgen will generate a random UUID each time it runs.Įxecute the following command in your terminal: To generate a single UUID, run the uuidgen command without any arguments. Next install the uuid-runtime package using the apt package manager: On Ubuntu and Debian systems, install the uuid-runtime package.įirst, update your system’s list of available packages using the apt update command: If it’s not, you can install it through your package manager. The uuidgen command is often already installed on Unix-like operating systems like Linux and macOS. In this tutorial you’ll use uuidgen and some shell scripting to generate UUIDs and some sample data. To generate universally unique identifiers from the command-line interface, you can use the uuidgen utility, Need a bunch of random string? UUIDs will be unique, making them easy to track down as they move through a system. Because of their uniqueness, they come in handy in situations where an auto incremented primary key can fall short.īecause of their uniqueness, UUIDs are well suited for generating test data. Universally unique identifiers (UUIDs) are 128-bit numbers that are accepted as being unique on the local system they are created on as well as among the UUIDs created on other systems in the past as well as the future.
