The command "xsv count ${filename-csv}" is a command-line instruction to count the number of rows in a CSV file using a tool called xsv.

Here's the breakdown of the command:

• "xsv" is the name of the command-line tool used for working with CSV files.

• "count" is the specific action or subcommand of xsv that we want to execute. In this case, we want to count the rows.

• "${filename-csv}" is a placeholder for the actual filename of the CSV file you want to count the rows of. The "${filename-csv}" part should be replaced with the actual filename, including the file extension ".csv".

So, when you execute this command by replacing "${filename-csv}" with the name of a CSV file, xsv will count the number of rows in that file and display the result.
