The command "parquet-tools dump ${path-to-parquet}" is used to display the content of a Parquet file in a human-readable format on the command line.

Here's an explanation of each component of the command:

• "parquet-tools" refers to the Parquet command-line tools, which are a set of utilities provided by the Parquet project for handling Parquet files.
• "dump" is a specific command within the parquet-tools utility that allows you to inspect the contents of a Parquet file.
• "${path-to-parquet}" should be replaced with the actual file path (including the file name and extension) for the Parquet file you want to examine. The "${}" notation is often used in command-line instructions to represent a placeholder that should be replaced with a specific value.

By running this command with the appropriate path to a Parquet file, you will be able to see the metadata, schema, and a sample of the data stored within the Parquet file.
