NAME

LRpt::CSVDiff - A module for comparing 2 sets of csv files

SYNOPSIS

  lcsvdiff.pl --all --keys_file=rkeys.txt --chunk_size=num before_dir after_dir 

DESCRIPTION

This module is a part of LRpt (LReport) library. It is used to compare 2 sets of csv files and report found differences. You should not use LRpt::CSVDiff module directly in your code. Instead you should use lcsvdiff.pl tool, which is a simple wrapper around the module. lcsvdiff.pl looks like this:

  use LRpt::CSVDiff;
  use strict;
  
  diff( @ARGV );
  

COMMAND LINE OPTIONS
