cloud-init: Query cached instance metadata for data.
$ cloud-init query ${dot_delimited_variable_path}
try on your machine

The command "cloud-init query ${dot_delimited_variable_path}" is used in cloud-init, a widely used multi-distribution package for bringing up a virtual machine in a cloud environment. It allows you to retrieve specific configuration values or metadata information from the cloud-init metadata source.

The command takes an argument, "${dot_delimited_variable_path}", which represents a path to a specific variable or metadata value. The path is given in a dot-delimited format, similar to a file system path. It allows you to traverse the metadata object structure and access specific values.

For example, if you wanted to retrieve the value of a variable named "my_variable" nested inside an object called "my_object", the command would be:

cloud-init query my_object.my_variable

By executing this command, cloud-init will fetch the value associated with the specified variable path and display it as the output of the command.
