uuid: Generate multiple UUIDv4 identifiers at once.

uuid

$ uuid -v ${4} -n ${number_of_uuids}

try on your machine

The command you provided:

uuid -v ${4} -n ${number_of_uuids}

In this command, uuid is a command-line tool used to generate Universally Unique Identifiers (UUIDs).

The command has two arguments:

-v ${4}: This argument specifies the version number of the UUID to generate. ${4} is a placeholder that indicates the value is taken from the fourth argument passed to the command when executing the script or command.

For example, if you run the command as uuid -v 1, it will generate version 1 UUIDs. The specific behavior and structure of each UUID version may vary.
-n ${number_of_uuids}: This argument specifies the number of UUIDs to generate. ${number_of_uuids} is another placeholder that represents the value of the variable number_of_uuids. The actual value of number_of_uuids is set outside of this command and can be any valid positive integer.

For instance, if you run the command as uuid -v 4 -n 5, it will generate 5 UUIDs of version 4.

In summary, the command invokes the uuid tool and generates a specified number of UUIDs with a specified version. The specific version and number of UUIDs are determined by the values provided for ${4} and ${number_of_uuids} respectively.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
