Terminal command for size of a database

Hi guys.
Is there any command to know the size of a database on disk (columnstore) and RAM (rowstore)? I saw that memsql studio provides this information, but would there be a terminal command for it?

This information is available in the information_schema database in the mv_columnstore_files, table_statistics, and columnar_segments tables. For example, this query will give you how much columnstore and rowstore data you have for each of your databases:

SELECT rowsegs.database_name,
       rowstore_in_gb,
       columnstore_in_gb
FROM   (SELECT database_name,
               Round(Sum(memory_use / 1024 / 1024 / 1024), 3) AS rowstore_in_gb
        FROM   information_schema.table_statistics
        GROUP  BY database_name) rowsegs
       LEFT JOIN (SELECT database_name,
                         Round(Sum(compressed_size) / 1024 / 1024 / 1024, 3) AS
                                                           columnstore_in_gb
                  FROM   information_schema.columnar_segments
                  GROUP  BY database_name) colsegs
              ON rowsegs.database_name = colsegs.database_name;
