The command "csvstat -c ${2,4} ${data-csv}" is used to analyze and display specific columns in a CSV (Comma Separated Values) file.
Here is a breakdown of the command:
-
"csvstat": It is a command-line utility or program that is designed to provide statistical analysis and summary of CSV files.
-
"-c": This option specifies that we want to display specific columns from the CSV file.
-
"${2,4}": This is a parameter or argument passed to the "-c" option. It indicates the range of columns to be displayed. In this case, columns 2 and 4 are selected.
-
"${data-csv}": This is another parameter passed to the command. It specifies the CSV file name or its path/location. "data-csv" is just a placeholder and should be replaced with the actual name or path of the CSV file you want to analyze.
Overall, the command will extract and display columns 2 and 4 from a CSV file specified by the "data-csv" parameter. The output will provide statistical analysis and summary of the data in those columns.
