Debian <\/strong>is an operating system that provides multiple packages such as \u201cdbus-bin\u201d, \u201cuuid-runtime\u201d, etc. to perform different tasks. UUID <\/strong>is an abbreviation for Universally Unique Identifiers. UUIDs are quite powerful and can be used to create useful data on the command line interface with shell scripting.<\/p>\n

This article will demonstrate the installation and usage of UUIDgen in Debian 12.<\/p>\n

What is UUIDgen? <\/strong><\/h2>\n

To create Universally Unique Identifiers, we use a tool known as UUIDgen<\/strong>. UUIDgen is a convenient tool for programmers and administrators. It helps to identify our resources uniquely. The UUIDgen tool generates a new universally unique identifier with the help of the \u201clibuuid library\u201d.<\/p>\n

How to Install UUIDgen in Debian 12?<\/strong><\/h2>\n

To install the UUID runtime package, simply use the command given below:<\/p>\n

$ <\/span>sudo<\/span> apt install<\/span> uuid-runtime<\/div><\/div>\n

<\/strong><\/p>\n

After installing the \u201cuuid-runtime\u201d package, a single UUID user can be generated using the following command:<\/p>\n

$ <\/span>uuidgen<\/span><\/div><\/div>\n

The following output will be displayed with a different UUID:<\/p>\n

<\/strong><\/p>\n

To create time-based UUIDs, use the \u201cuuidgen -t\u201d command as shown below:<\/p>\n

$ <\/span>uuidgen<\/span> -t<\/span><\/div><\/div>\n

<\/strong><\/p>\n

To generate a random UUID use \u201c-r<\/strong>\u201d along with \u201cuuidgen\u201d using the command:<\/p>\n

$ <\/span>uuidgen<\/span> -r<\/span><\/div><\/div>\n

<\/strong><\/p>\n

How to Generate Multiple UUIDs?<\/strong><\/h2>\n

To create a list of UUIDs at once, we will shell scripting using a for loop. To retrieve a list of 10 UUIDs use the command:<\/p>\n

$ <\/span>for<\/span> i in<\/span> {<\/span>1<\/span>..10<\/span>}<\/span>; do<\/span> uuidgen<\/span>; done<\/span><\/div><\/div>\n

We can see that 10 UUIDs are displayed on the screen as shown below:<\/p>\n

<\/strong><\/p>\n

How to Use UUIDs in Test Data?<\/strong><\/h2>\n

To display a list of comma-separated values (CSV) along with Two UUIDs per line, we use the echo command with a \u201cfor loop\u201d. Execute the command shown below:<\/p>\n

$ <\/span>for<\/span> i in<\/span> {<\/span>1<\/span>..10<\/span>}<\/span>; do<\/span> echo<\/span> `<\/span>uuidgen<\/span>`<\/span>,`<\/span>uuidgen<\/span>`<\/span>; done<\/span><\/div><\/div>\n

This will create a CSV with two UUIDs per line:<\/p>\n

<\/strong><\/p>\n

Similarly, we can create data with email addresses by using the following command:<\/p>\n

$ <\/span>for<\/span> i in<\/span> {<\/span>1<\/span>..10<\/span>}<\/span>; do<\/span> echo<\/span> `<\/span>uuidgen<\/span>`@`<\/span>uuidgen<\/span>`<\/span>.com; done<\/span><\/div><\/div>\n

<\/strong><\/p>\n

These aren\u2019t real email addresses, but we can change the above command a bit and replace the second uuidgen with an email address domain like \u201cjunkfilter.com\u201d as shown below:<\/p>\n

<\/p>\n

 <\/p>\n

Conclusion<\/strong><\/h2>\n

UUIDs are quite powerful. To install UUID in Debian 12, use the \u201csudo apt install uuid-runtime<\/strong>\u201d command. To generate a single user use the \u201cUUIDgen<\/strong>\u201d command. We can create hash-based and time-based UUIDs using the \u201cuuidgen -t\u201d and \u201cuuidgen -r\u201d commands. We can also create data like email addresses using the \u201cfor i in {1..10}; do echo `uuidgen`, `uuidgen`; done<\/strong>\u201d command.
