The command "cradle sql populate ${package_name}" is using a tool or script called "cradle" to populate a SQL database.

Here is an explanation of the different parts of the command:

• "cradle" is the name of the tool or script that is used to interact with the database and perform various operations.
• "sql" is specifying that the operation to be performed is related to SQL, which is a relational database management system.
• "populate" is the specific action to be taken by the tool or script. In this case, it means that the database will be filled with data.
• "${package_name}" is a placeholder or variable that should be replaced with the actual name of a package or dataset. It specifies which specific data package or set of information should be used for populating the database. The actual value for this variable should be provided in the command.

By executing this command, the "cradle" tool or script will connect to a SQL database and populate it with data from the specified package or dataset. The purpose of this command could be to initialize a newly created database with some initial data or to update and refresh the data in an existing database.
