The command you provided is a syntax for the fselect tool, which is a command-line utility used for querying and parsing file system directories. Let's break down the command and understand its components:

fselect: This is the command to run the fselect tool.
"${MIN(size), MAX(size), AVG(size), SUM(size), COUNT(*)} from ${path-to-directory}": This is the query enclosed in double quotes and consists of two parts.
- ${MIN(size), MAX(size), AVG(size), SUM(size), COUNT(*)}: This section specifies the calculations to be performed on the "size" attribute of the files. It includes the minimum size (MIN), maximum size (MAX), average size (AVG), total size (SUM), and count of files (COUNT(*)). These are aggregate functions used to compute different statistics on the size attribute.
- from ${path-to-directory}: This section specifies the directory path from which the files should be queried.

Overall, the command executes the fselect tool with a query that retrieves various statistics on the size attribute of files in the specified directory. The tool will provide the minimum, maximum, average, total size, and count of files in the directory.
