The xsvutils tool provides subcommands for filtering, sorting, and joining CSV data. Some subcommands include cut to select columns, where to filter rows, sort to sort rows, and join to merge files. Multiple subcommands can be combined, such as joining two files and then filtering the columns of the output.
